Introduction

Overview
The main purpose of the Wizard 8.2 is to create new scheme calibrations. Those are used by
neoStampa 8.2 to print under the same conditions on the desired media. Following through the Wizard
8.2 you can print different kind of test charts, in order to control and set ink amounts, linearization
curves and maximum ink limits, as well as printing a ICC target and create a ICC printer profile.
The most important difference from neoStampa 7 calibration wizard is that this new version offers a
better control of the ink limit -and therefore better dark and light transitions-, and in some cases larger
gamut. This Wizard 8.2 also offers the option to check existing calibrations, without having to go
through the whole process of measurements.
In this User Manual you will find descriptions of the options that the Calibration Wizard offers, and
extensive explanations as of various processes and aspects involved in this process.

New Features
- Fluorescent Inks support
- ICC Profiler parameters selection (presets)
- Scheme grouping
- LAB color charts
- Create ColorChart from spot color replacement window

Enhancements
- Option to enable/disable log organisation per day
- Added 400% ink limit test and defaulted ink limit to 400%
- Enhanced i1Pro device calibration system
- Color picker auto-selects object
- EPS HiResBoundingBox detection
- Crop rectangle mark is movable using bleed value
- Object information text, possibility to follow/unfollow object mirroring
- Possibility to set 2-step color replacement (Spot->Lab->Lab)

Calibration Wizard 8.2.0 Introduction – 6/58

Get Started with Calibration Wizard

Before starting
We recommend to follow the next notes to avoid calibration mistakes during the calibration process.
• Pay attention in nozzle print quality in your digital machine. Make sure to do the nozzle check
before you start a new calibration.

Before nozzle check: After nozzle check:

• Full calibration process must be printed UNI - directional (ink limit, linearisation, target, test
chart) . The same step is to follow for print samples when they want to be matched with other
printed samples. In the later production the directional can be switched to BI-directional.
• Printing always in same direction (horizontal OR vertical) to secure the same printing
environment during the calibration process and making an average in neoStampa 8.2, which
means reading two target charts.
• Using one and the same spectrophotometer device, calendar, steamer or dryer for every each
printout during the calibration process.

Calibration Wizard 8.2.0 Get Started with Calibration Wizard – 7/58

Start the Wizard
Calibration Wizard is embedded in neoStampa installation and can be started after neoStampa is
installed on your computer. Check your license and make sure that your license allows calibrations.

 Refer to neoStampa User Manual to read about the installations and activations.

Access the Calibration Wizard 8.2. from the Printer Scheme Manager in neoStampa's 8 upper bar on the
main window with button .

The Calibration wizard button is at the bottom left

corner of the Printer scheme manager.
Or else, start the wizard with the shortcut on the
PC desktop.

The program opens at clicking on the Wizard button.

Calibration Wizard 8.2.0 Get Started with Calibration Wizard – 8/58

Calibration Options
In the first window of the Wizard you are required to introduce the most basic information for the
calibration. The buttons at the bottom (apart from Configure) allow to move through the different
windows of the Wizard, and to Exit the Calibration, whether saving it or not.

Calibration Wizard 8.2.0 Calibration Options – 9/58

Printer Selection
In the upper part of the window are the settings
of the printer you want to make the calibration
with.

Hitting the tab-down button with three dots will

allow to add a printer to the list of printers that
you already have. In the opened window, the
Add and Remove buttons allow you to introduce
the printers you require in the list of installed
printers.

 Refer to neoStampa User Manual to read more about Printer Configuration.

Actions Selection
There are three options in the Action selection field. The two first ones are described following.

Start a new calibration

The first is to Start a new calibration, in which you
need to fill in the information as for Media name,
Ink type and Quality. Inèdit recommends to
include all this information, as your scheme will
be easily identified. Anyway, the name of the
scheme can be changed later on.

You have the possibility to group the schemes. All

you need to do is to add "@" in the name, where
the name should be split to use the information
as sub group.

Calibration Wizard 8.2.0 Calibration Options – 10/58

 When the scheme is completed, later in
neoStampa you will see the scheme group when
load and open printer scheme.

Legacy mode, when activated, will use the older profiling engine of neoStampa 7, and therefore a
different process.

Continue an existing calibration

The second option is to Continue an existing
calibration. Just open the drop-down list and
choose the one you need. Clicking on the
checkbox to load the already completed
calibrations or duplicated selected schemes.

If you want to load grouped scheme load the

scheme and select the group.

Check printer and/or profile consistency

This is a very useful tool to check if the profiles
that you have already generated still keep the
same quality. However, if you need to change
inks, or media, this re-profiling is not the tool to
do as you should make a whole new
calibration. Refer to its own chapter Printer
consistency test in this document to learn how to
use the option.

Calibration Wizard 8.2.0 Calibration Options – 11/58

Configuration of Spectrophotometer
At the bottom of the window, as we have seen,
there is the Configure button, which will open the
window to set the device you are going to use for
measurements.
Depending on the device you use, the options for
Transparency, Zebra ruler or UV filter will be
activated or not.
The Illumination and the Observer can be
selected for the measurements.
The Color management option in this window
allows to select whether to work with the new
neoStampa 8.2 profiler, -set as recommended-or
the old neoStampa 7 one.

 Refer to neoStampa's supported spectrophotometer User Guides in Support Materials: http://

Calibration Wizard 8.2.0 Calibration Options – 12/58

Print Configurations
Print configuration establishes color specifications such as for Color mode, Print quality and Dithering
in the second window of the Wizard.

Quality
The content of this window is driver specific. Quality is usually printer dependent and is provided by the
driver specifications of each printer.
In the Advanced… button next to it, you can see and change if necessary printer specific parameters,
such as single or bi-directional printing, number of passes, etc.

Calibration Wizard 8.2.0 Print Configurations – 13/58

Color Mode
The Color mode is selected from a drop-down list. The available selection depends on the printer
specifications. For standard plotters from main companies such as Epson, Canon, Hp, etc., some
presets will appear on the list, where inkset and order are set automatically. Press the three dots button
to specify these parameters if the plotter has been modified by any third party, or for direct printing
models.

Inkset Order
Press the three-dots button on the right of Color mode to set the color order for the selected mode.
Apart from that, you can also set other parameters such as multiple inks or fluorescent inks
calibration from the window that pops up.

Set color order : On the left side of the window, set the inks in use according to your machine
specifications or to the previously printed mini chart. There are many inks available and make sure you
select the correct ones. Be careful when selecting Gray and Light Gray, as the latter can only be used if
Gray is present. Gray is sometimes called Light Black by certain ink suppliers, and Light Gray would be
Light Light Black for those too.

Calibration Wizard 8.2.0 Print Configurations – 14/58

Fluorescent inks : Fluorescent inks are indicated as Fluor Cyan, Fluor Magenta, Fluor Yellow and Fluor
Green and must be not handled as Spotcolors anymore.

Print… : In case you are not sure what ink order is loaded in you printer, you can print out a chart
showing a number for each printed base color. Certain printers have a special ink order coming from
the driver documentation (e.g. Epson, Mutoh). It is recommended to print out this chart if you are not
sure of the order or if you encounter strange color effects during the calibration process (e.g. Black
prints Cyan).
Set color order : On the left side of the window, set the inks in use according to your machine
specifications or to the previously printed mini chart. There are many inks available and make sure you
select the correct ones. Be careful when selecting Gray and Light Gray, as the latter can only be used if
Gray is present. Gray is sometimes called Light Black by certain ink suppliers, and Light Gray would be
Light Light Black for those too.
Ink curve : Ink transition curves for single inks. Provides the Coverage (%) function for specific, delicate
inks such as Yellow and Pink.

Calibration Wizard 8.2.0 Print Configurations – 15/58

Double Ink
You can place the same ink into different slots multiple times. If you do so, the Double Ink… button is
activated and lets you specify the behavior of those inks.

Channel : Toggle between the multiple inks. For each ink you can set an individual curve behavior. The
use of multiple inks is basically to make the total color get darker or more saturated. Setting different
behaviours for each channel enables special effects, such as minimizing dithering in lighter areas. A
consideration in this software-based approach of multiple inks lays upon the fact that certain
printheads are more used than others. Finally, the combination of multiple inks, including all the set
parameters, are linearized as one new ink. We recommend that at least one channel should be linear
and that you should NOT change the parameters after you have linearized the combo. Absolute ink
limit calculates the total sum of inks and compares it to the defined maximum value. If this is higher
then lower, all the inks proportionally, except the Black, to keep the shadows. When you have two
blacks in the inkset, you have to decide which one of the two will remain untouched after the ink limit
reduction. Therefor the checkbox Master black becomes available in combination of double black inks
only. Here one of the black inks can be selected and set as the master black ink to keep untouched.

View curve : It presents the behavior of the curve for the selected ink. Make sure that it looks smooth,
if you want to obtain homogeneous results. You can change the Start, Body and End by increasing or
decreasing the values below.
• Start: This value defines where the ink starts. 25 means that the selected channel will not print
below 25% of original coverage.
• Body: This value defines where the ink starts. You can try different values to evaluate which ones
are the most suited to deliver a smooth shape. 75 is a good value if Start s at 25% and End at
100%.
• End: This value should usually be set at 100, since the idea is to get darker color. Note, however,
that in some cases you might have too much ink, and you may have to reduce it in the ink cut
procedure, which will be explained further on in this manual.

Calibration Wizard 8.2.0 Print Configurations – 16/58

Mask
If you have special inks loaded, such as a penetration liquid, dilution ink, mask or white inks, you can set
parameters for this in the Mask channel settings window. The Mask ... button becomes available when
you select one of the following inks: Mask, White (background), Dilution ink.

Get from alpha channel : As the name says, the image to print requires an additional Alpha channel
added to the image, e.g. manually created in Photoshop. The ink then uses the channel information to
print the content. Depending on the printer, the ink will be printed in a separate pass or simultaneously
with the other inks.

Full mask : neoStampa will create a flat color underneath the image whenever a pixel is present (with
Photoshop: always; with Illustrator or CorelDraw: whenever an object contains a color information, such
as white). Note that the full mask generation is only done if the image is in Grayscale, RGB, CMYK or
LAB, but not with multichannel files. So, when printing linearization targets the full mask will not print.

Shadow mask : neoStampa will create an intelligent grayscale mask under the image information
according to its color intensity and color darkness. Usually, this mode is used when printing white ink,
e.g. for T-shirt printing. Note that the Shadow mask generation is only done if the image is in Grayscale,
RGB, CMYK or LAB, but not with multichannel files. So, when printing linearization targets the shadow
mask will not print, but it will be generated when printing the ICC target.

Fill ink : This method is usually used for penetration liquid or for a fill-up ink, such as dilution inks or
similar. The penetration liquid is provided by several ink suppliers with the idea of helping inks in lower
percentages to penetrate through the textile media. The fill ink method needs specifying an Intensity
and Minimal value explained underneath.

Put ink in white pixels : Usually white pixels do not require a penetration liquid or dilution ink-since
the area is not printed anyway- , which results in ink savings. In certain printing environments (e.g.
carpet printing using Zimmer ChromoJET800) this check-box helps to create a blocking area around the

Calibration Wizard 8.2.0 Print Configurations – 17/58

colored image using dilution ink to prevent colors from bleeding into non-printed areas. Note that
"white pixels" refer to an image information with an object containing no color (with Photoshop: always;
with Illustrator or CorelDraw: whenever an object is found containing a white color).
Intensity : The Fill ink method will fill up with dilution ink, whenever this specified value is not reached
by the absolute amount of other inks in the ink set. So, when you print 10%
Cyan+25%Magenta+30%Gray, the absolute amount of ink will be 65%. In this case, neoStampa will
automatically add a 35% of dilution ink for better penetration.
Minimum value : Specifying a minimum value for the Fill ink method adds a certain amount to an
absolute ink amount in any case. Scenario: If you set intensity to 100% and the Minimum value to 10%
and the absolute amount of ink of 25% Cyan+35% Magenta+ 75% Gray exceeds the 100% of specified
Intensity, then neoStampa will add another 10% on top of it. This will help the ink to penetrate even
more, but can also cause a certain amount of bleeding if applied too much. This value should be used
with care.

Calibration Wizard 8.2.0 Print Configurations – 18/58

Dithering
neoStampa 8.2 provides different raster methods. Two of them are the most common to use: Smooth
Stochastic (default) and Diffusion v2.

Smooth Stochastic (by default)

This raster is a matrix-based method, which places the dot matrix in the most homogenous way and is
recommended for all types of inkjet printers. It is however also a complicated method since, especially
with n-level printheads (e.g. 2bit, 3 levels, "grayscale" printheads), the nozzle can suffer from stress. The
new Smooth Stochastic method is a complete re-development from very scratch based on the original,
previous Smooth Stochastic halftoning. It provides many options to control individual drop levels, drop
coverage as well as activating or deactivating single drops. This explanation should give you an overview
on the many settings and combinations that can be done mainly to prevent specific printing issues or
linearity behavior.

Settings

Select the raster method from the drop-down menu.

 The following settings are available only when the printer driver
supports 2 bpp (bits per pixel). Otherwise it uses the standard
settings as is explained for diffusion and other dithering.

The button with three dots on the right of the list

allows to set drop configuration for the full ink set
in coverage (%) and drop weight. By default the
values are 100.00 % coverage and 1.00 to 3.00
drop weight. DropRelaxer® relieves the heads
using averaged % value. Also the configuration
can be done per ink when checking Customize per
ink.

Calibration Wizard 8.2.0 Print Configurations – 19/58

 The button Legacy… opens the dialog to set extra halftone settings in
dot gain compensation.

Diffusion v2 (for variable dot printheads only)

This raster is based on a Smooth Stochastic matrix, but adds some error diffusion to the final raster.
This method puts holes into the regular matrix in order to give the nozzle time for relaxation. The aim is
to prevent banding occurring from the previously mentioned stress factor. The raster method is
homogenous as well, but since certain dots are removed it might be that the dot placement does not
look as "perfect" as with Smooth Stochastic. You can set the Diffusion v2 amount of error in the three
dots placed next to the drop down list (explained later in this tutorial). Available color modes depend on
the printer specifications.

Settings

Select the raster method from the drop-down menu.

The button with three dots on the right of the list allows to set different
types of dots, which we explain following.

Disable large dot : If you have a delicate media that cannot pick up a lot of ink, disabling the largest dot
(available with 2bit / 3 or more level printheads only!) can help. It can also help if the printhead has
problems firing the large dot, but this is quite a rare scenario. As the name says, the largest dot will not
be produced during rastering. We recommend however not to use this function as reducing ink in the
per-channel ink cut provides more control.
Disable small dot : In some printing environment using certain printheads, the small dot never reaches
the media since a combination of a small dot with high printing carrier movement speed, and/or

Calibration Wizard 8.2.0 Print Configurations – 20/58

electrostatic charge (e.g. using polyester fibre), deviates the dot so much that it is literally blown away.
This can cause a lot of residual ink in the environment ,and the dust is placed anywhere, an effect that
is certainly not wanted. Using this function switches off the usage of the smallest dots (available with
2bit/3 or more level printheads only ! ).
Only for black ink : If this box is selected in combination with "Disable small dot", then the smallest
dot is only omitted in the Black channel(s).
Smoothness : This value becomes available when working with Diffusion v2 raster method in
combination with an n-Bit / n-Level printhead. The smoothness defines the amount of error introduced
to the matrix raster to avoid stress from the nozzles when firing full-time (mentioned in Dithering Part
1). A smoothness of 10 means that Diffusion v2 does not have any error diffusion (=Smooth Stochastic).
By decreasing this value, dots are removed from the regular matrix and the n-Levels of variable drop
technology are diffused into each other. A value of 6-9 delivers a good balance between quality and
stress-reduction to printheads with variable dot technology. If you go lower than this value, there can
be too much noise in the result and the print-out will go grainy. We recommend a value of 7 if you
encounter such a firing stress problem. Note that changing to Diffusion v2 or changing the amount of
Smoothness requires re-linearizing the printing conditions.

Dot multiplier : This value must be left at "1". Note: We recommend NOT to change it.

Ordered Halftoning
Select the raster method from the drop-down menu.

It is possible to establish for each ink the angle of

the screen the frequency (l/in, l/cm) and the dot
shape, although the most common procedure is
to use the same one for all the channels. To select
the dot shape, select the list of supporting shapes
for printers.

Calibration Wizard 8.2.0 Print Configurations – 21/58

 The frequency of the dither can be introduced in
lines per inch or centimeter. Based on the
resolution of the printer, the software calculates
the frequency and angles that best approximates
what has been introduced.

Depending on the value of the selected "Super Cell", the adaptations of angles and frequencies will
differ.
• The value 1x1 is the one which best defines the shape of the dot, calculating the angles and
frequency which best matches with the resolution of the printer. However, it can sometimes lose
gradations of grey tones.
• The value 4x4 will not define with such precision the shape of the dot, but it generates more
gradations of grey tones.

Other Dithering halftones

The other dithering halftone methods are based on diffusion method
using different types of dots and using the same settings as diffusion
method.

Calibration Wizard 8.2.0 Print Configurations – 22/58

Ink Limit and Linearization
Once we have set up the different printing parameters, now it is time to start printing step one of the
calibration process. To complete this window of the Wizard there are three very important steps that
need to be done, and they need to follow an order, always from top to bottom:

Calibration Wizard 8.2.0 Ink Limit and Linearization – 23/58

Step 1 - Ink Limit
We will now start to ink control and linearize our
printing conditions.

You are able to print up to 400% of ink, to find the best absolute ink limit
for your media on the test file. By default 400% are used. The Extra
options allow for a calculation of different inks together.

Print out the absolute ink limit chart. The interpretation and usage is explained later in this document.

Calibration Wizard 8.2.0 Ink Limit and Linearization – 24/58

Print configuration - Ink Limit
Before the actual print, a window opens with a
preview of the charts, where you can adjust
parameters.

Position and orientation : You can set here printing parameters, such as orientation (portrait or
landscape), mirror printing (transfer printing), horizontal and vertical position, copies and scaling. With
spectrophotometer and single ink limit chart as well as linearization chart we recommend to use
portrait printing in combination with 100% scaling.

Page setup : Define the page settings here. The width will present the layout of the placed chart. You
can either set roll media (in nite) or cut sheet media (with a certain length).

Printing parameters : Printer driver specific parameters can be altered here, such as uni- or bi-
directional printing or cut sheet at the end of the print out. Depending on the printer, additional
printing parameters can be adjusted inside the Advanced… window. As explained in the chapter Print
Configurations the advanced window only shows printer specific parameters provided by the driver
documentation of the printer manufacturer. Usually you can set here the amount of passes, overprint,
feed adjustment, etc. But since you've probably set all the parameters in a previous window it is not
required that you change them here.

Layout preview : This part of the window shows how the chart will be printed. Note that neoStampa's
layout is generally 90° rotated counter-clockwise, so from left bottom to left top will be your printer's
media width. If the media width in page setup is smaller than the chart's width, the chart will be cut
automatically.

Channel order : Since the charts in the ink cut, linearization, ink limit and rich black (black addition) are
based on a multichannel file format, the channel order will be considered in such a way that the main
channels K,C,M,Y are automatically re-arranged to the top four positions. We recommend not to re-
arrange the order of the channels here.

Ok / Cancel : Click Ok to print the chart or Cancel to exit the window without printing.

Calibration Wizard 8.2.0 Ink Limit and Linearization – 25/58

Print chart evolution
To evaluate the test chart make sure that the print has dried and - if using textile material - fixated or
steamed and washed.

 For some other medias like paper, cutting inks criteria is different. In those, it should be entered
the maximum percentage of ink before any irregularities-blurred, stripped, matte, wet print-
appear.

Chart Result A

Ink-prelimitting is not required because, neoStampa uses Ink Limit Control with default cut at 400%.

Calibration Wizard 8.2.0 Ink Limit and Linearization – 26/58

Chart Result B

Ink-prelimitting is required, because the linearization strips are bleeding lower than 400%.
If all of the color-mix patches are bleeding you should first try to find out whether the material is not
suited for the inks or the print has been made with a too high resolution. In the image example the
recommended cut would be between 170% and 175%.

After you can try to limit globally entering the

percentage shown below the first patches that
show bleeding in Ink Limit field and reprint the
chart using the Print... button under. It's
recommended to try several ink cuts until you
reach a reasonable printout that does not require
pre-limitting.

Calibration Wizard 8.2.0 Ink Limit and Linearization – 27/58

Step 2 - Single Ink Cut
This step is required only when light inks are in
use. You are able to cut single ink limit. Therefore
you need to print a CMYK plus light inks test
chart, with gradient 0%-100%.

Print out the single ink limit chart.

Once again, before the actual print and measurement, a window opens
with a preview of the chart, where you can adjust parameters (ink
channel, print direction, position, orientation, page setup). When the
above parameters are set, press Ok to print the test file.

Calibration Wizard 8.2.0 Ink Limit and Linearization – 28/58

Measurement - Single Ink Cut
Once the print is ready washed and dried or vaporized proceed with the Measurement. Press the

button and connect the spectrophotometer. Then start reading the lines carefully and
slowly according to given specifications.

Notice that the Calibration Wizard 8.2 offers the

possibility to get 3 measurements for each print.
This is useful when for example the media is
rough, and we want to get much precise results.
The Wizard will produce average values from the
2 or 3 measurements.
Notice also that the data for this measurements
and of each reading can be exported with
Export…, if necessary, they can also be imported
with Import… button.

In case of measurements errors the red squares

around the patches showing possible errors
warnings. With the Error tolerance regulator the
warnings can be filtered looking for higher DeltaE
values.

Pressing right-click mouse on the red square it opens the Spectrum visor
showing the spectral curve of the selected chart patch.

Calibration Wizard 8.2.0 Ink Limit and Linearization – 29/58

Measurement evaluation
When you finish the reading, the Densities and
Ink cut dialog will pop-up. This dialog shows the
measurement results based on LAB
measurements per color. The Wizard will perform
an automatic ink cut, based on the values
obtained. The new values are based on 100% of
ink. The single cut will be measured by the
software. If you toggle through the inks with the
radio- button checked left of to the ink name's
short-cut, you can view each ink density curve.
The data for the measurements can be exported
with Export… or imported with Import… buttons.

Light inks transition

In Light inks transition you can pre-set the best ink transition. It offers some possibilities to increase or
decrease the amount of light ink used in the dark and light calculation. The recommended mode is
"Normal" .

The Advanced… button will take to another window where more

settings can be applied for the light inks. Only very expert technicians
should change any of them.
If you have a very delicate media and encounter light ink excess, such as
with glossy paper, you can toggle to use "Less light ink".
If you need more light ink because your printhead has a low resolution
or because you'd like to have more penetration using more light ink,
then you can toggle to use "More light ink". Be careful with this mode
since you might encounter some light ink excess.

Calibration Wizard 8.2.0 Ink Limit and Linearization – 30/58

Without Light inks

If your calibration is done without Light Inks, then

step 3 can be avoided if none of the inks are cut
at less than 60%.

When the inks are cut at a 60% or more, an option

at the bottom right of the window appears.

Ticking this option, the measurements will be

used and no other test charts will need to be
printed, as the densities performance is already
done.

Calibration Wizard 8.2.0 Ink Limit and Linearization – 31/58

Step 3 - Linearization
In Linearization, you are able to see the
performance of CMYK ink set with light ink set in
post-linearization curves.

Therefore, you need to print a CMYK test chart

with gradient of 0%-100%. Even without using
light inks, you need to measure the
Linearization. If you made ink cut in step 2,
forward to print in step 3. If you made no
changes, simply measure the printout from step
2.
Print out the linearization chart.

Once again, before the actual print and

measurement, a window opens with a preview of
the chart, where you can adjust parameters (ink
channel, print direction, position, orientation,
page setup). When the above parameters are set,
press Ok to print the test file.

Calibration Wizard 8.2.0 Ink Limit and Linearization – 32/58

Measurement - Linearization
After printing the test file, proceed to connect the
spectrophotometer, as you did before. Press the

button and connect the

spectrophotometer. Then start reading the lines
carefully and slowly according to given
specifications.
Also here, the possibility to get 3 measurements
for each print is given. The Wizard will produce
average values from the 2 or 3 measurements.
Same options as shown in Single Ink Cut to import
and export measurements with Export… and

Densities and ink cut

When you finish the reading, the Linearization

performance will pop-up with Densities
dialog. You will see the density values and the
automatic ink cut calculation results. You can view
all the curves together, or one by one. The new
values are based on 100% of ink. The data for the
measurements can be exported with Export…
or imported with Import… buttons.

 Click on Ok to continue with Linearization dialog.
Or else, click on Densities… if you continue with
an existing calibration.

Ink Control

The next windows will pop-up with Ink Control

dialog. It shows the response curves window. We
can make some adjustments so as to improve the
result, if certain tones aren't as expected.
The data for the measurements can be exported
with Export… button.

It is possible to modify graphically any of the color

channels adding new points, by pressing on the
line in a zone where there is no point, or modify
the position of a point by pressing on it and
displacing it onto a new position. Toggle between
the channels to change the view of the
linearization curve to the actual selected ink.

 Only correct a curve if you really think that

a certain point is shifted due to
measurement irregularities as shown in
the example below.

Input and Output values of each curve can also be modified manually, from the fields on the right. The
option Reset Ink erases all the points of the selected curve, which implies that no linearization will be

Calibration Wizard 8.2.0 Ink Limit and Linearization – 34/58

made. It is recommended not to use it. Only works in certain specific conditions, but NOT in usual
cases. The button Copy to all allows copying the reference points of a curve to all the other ones. In
case few points are entered, the option Smooth can be selected so that the resulting curve is smooth
and doesn't have rough changes in tonality adjustments. This function enables a 16bit interpolation
between the dots, which make a gradient much smoother. We recommend to always leave this button
on.

In certain extreme density

conditions, e.g. if your printer
has a strong linearization
correction, it is possible that the
last 1-2 points in the
linearization curves "touch" the
right side of the curve's border.
It's recommended that you
move the last 1-2 patches to left
in order to prevent that the
curve touches the side:

hueman V2 - Black Generation
After hitting "Next" in the ink cut, linearization and ink limit window you will now get to the part to
define the black generation of your printer calibration. This process allows to determine which
combination of inks provide the best black as well as to prevent dithering from black ink in light areas if
you don't have a gray ink in combination.

Calibration Wizard 8.2.0 hueman V2 - Black Generation – 36/58

Method
hueman v2 Black generation provides 3 methods to generate the black ink:

Default (Black Only)

This method is recommended if you have a very
good, strong black ink in your printer and if you
also have a gray ink (light black) that prevents
dithering from the black ink in light areas. In this
case the black generation will be black only.

Black Addition
This method is recommended if a combination of
inks is better than your pure black ink only, and if
you also have a gray ink (=light black) in the
printer to prevent dithering from the black in light
areas. Here, the black generation will add the
defined values of the additional inks to improve
the overall darkness of the result. You can use the
"Print.." button to determine whether a
combination of colors including black is better
than the black ink only.

Gray Component Replacement (GCR)

This method is recommended if a combination of
inks is better than your pure black ink and if you
don't have a gray ink (=light black) in your printer.
With this method CW8 will replace light areas of
black with a combination of CMY inks, to visually
minimize the dithering from the black ink. Be
aware that such a GCR can be critical since the
light fastness of C, M and Y are not always the
same and that after a certain time one of the inks
might fade faster than others resulting in a non-
neutral behavior of gray areas (e.g. outdoor flag
printing).

Calibration Wizard 8.2.0 hueman V2 - Black Generation – 37/58

Patch File
In order to evaluate whether a combination of inks is better than your pure black ink, you can use the
"Print.." button to print out a chart for visual analysis. You can select one of the charts in the list.

 Note that the multichannel file is a special color mode in Photoshop and may not contain CMYK
or RGB color channels on top. Save them in .psd format.

For most printers, the BlackAdd_CMYK.psd (or the smaller A4-sheet-

fitting BlackAdd_cmyk_A4.psd) will be enough.

If you have additional process colors, such as Orange, Blue or Red (not
light inks!), you can select the according patch file.
Example: If you have loaded Cyan, Magenta, Yellow, Black, Gray, Orange,
Blue, Red in your printer, chose the BlackAdd_CMYK+3. psd (or
_small.psd). Since Gray is a light ink, do not count it as +1 ink.

With button Add… you can add individual charts to print if you would like to test another set of
combinations. Be aware that the chart MUST be in multichannel format so you can arrange the channel
order in the "Print.." window. We recommend that you put at least 4 spot channels and name then with
Cyan, Magenta, Yellow, and Black, so that CW8 can auto-assign them to the proper ink channel.

Print
Print the selected chart for visual analysis. In
digital textile printing you should steam and wash
the chart since you want to see the final result (as
with all charts except with the ink limit charts in
most scenarios).
The default charts contain different combinations
of black with the other process colors. In the
center of each patch you'll find the 100% pure
black ink. Around the center is 100% black plus
the combination of inks with the values noted
aside. If you really find a black that is better
outside than inside (better=darker and/or more
neutral, etc.) you can use these values to fill them
into the "Rich black" fields.

Calibration Wizard 8.2.0 hueman V2 - Black Generation – 38/58

Rich Black
In the example above, the red circled patch has a
better black outside than in the center. We will
use K100, C60,M60, Y60 for the "Rich black" fields
for either Black Addition or GCR.

 Do not use extreme combinations, such as K100, C90, M90, Y0, since you might encounter other
problems that are not seen in this chart (e.g. light fastness, steaming stability, etc.). We
recommend to use a combination containing all values, such as K100, C60, M60, Y30 or K100,
C30, M30, Y30, for stability purposes.

Of course, only select a "Rich black" if the combination is really better than the black only, since you will
increase the ink amount, leading to higher production costs. Fill the determined values into the fields.
You can only use "Rich black" in combination with Black Addition or Gray Component Replacement
method.

Advanced
The advanced settings of black generation are
provided format experienced users only. Usually,
using the regular black generation window will be
sufficient to get a high-quality profile. Advanced
settings allow to fine-tweak or control certain
printing environments, but it can also lead to
wrong results if not used properly. Proceed with
care and use the default settings, whenever
possible.

• Revision: By default, CW8 will automatically select the latest color separation technology in the
revision list. The latest revision usually delivers the best result for each specific ink combination.
We recommend not to change the revision unless specifically instructed by your distributor or by
Inèdit.

• Profiling mode: The default profiling mode for neoStampa is RGB profiling. The profiler included
in CW8 (optional license) that creates the ICC profile will only work if RGB is selected. In addition

Calibration Wizard 8.2.0 hueman V2 - Black Generation – 39/58

 to this, all configuration parameters in the black generation will only be available with RGB
profiling mode. CMYK profiles can also be generated. However, CMYK profiles are basic because
no parameters of any kind can be selected for their generation- you will notice that most of the
options in this window become inactive when this mode is selected. The black generation using
CMYK profiling is usually defined by an external profiler.

• Balance: The "Balance" parameter allows to increase or decrease individual inks to balance the
black generation combination using Black Addition or GCR. Since the profiling process will correct
irregularities in the balance between inks, the "Balance" option is not really required, and the
values should be left at 1.0 In very rare occasions, a certain ink may be much stronger (or
weaker), in relation to others, and can be corrected here. The resulting curve will be displayed in
the Black generation preview, on the right of the window.

• Black start: The curve control area allows to specify certain conditions on the curve, such as
Black start, Body (light) and Body (dark). The Black start sets the start position of the black ink to
the defined value.
The default value for Black start using Black Addition is 33%. It means that the additional colors
to achieve a richer black will start to enter after 33%, and will reach the specified value at 100%.
Below 33% only black ink (including gray) will be used.
The default value for Black start using GCR is 20%. This means that below 20% of black
generation, no black ink will be present, but instead it will be replaced with a combination of C,
M, and Y inks. This is to prevent dithering of the black ink if no gray ink (=light black inks) is
present in the ink set.

• Body (light): The Body light parameter shapes the curve in the lower area of black generation.
The ideal value is experimental, but should result in a smooth and regular total curve shape,
which can be seen in the Black generation preview. The default value for Body light using Black
Addition is 83. The default value fro Body light using GCR is 33.

• Body (dark): The Body dark parameter shapes the curve in the upper area of black generation.
Also here, the ideal value is experimental and should result in a totally smooth behavior of the
final curve as seen in the Black generation preview. The default value for Body dark using Black
Addition is 100. The default value for Body (dark) using GCR is 66.

• Ink limit method. neoStampa includes two methods for ink limiting:
Smooth: The default method provides an intelligent ink limiting without clipping behavior in
heavy ink load areas. It optimizes the ink amount in extreme areas to provide smoother behavior
of gradients but sacrifices 2-3% of gamut.
Clip: The clip method just cuts down the exceeding ink to the defined value. Although the gamut
might be 2-3% larger in these extreme areas, it is possible that gradients in very dark areas are
not as smooth as with the above method.

• BlackOptimizer ®: This function improves the gamut behavior in colorful areas when moving
towards saturated, dark colors. Since specially in digital textile printing, the regular GCR method
doesn't always directly make a color darker, but turns it duller and sometimes even lighter, an
intelligent analysis of color-to-dark is required, to improve the combination of colors in the black
generation. BlackOptimizer does this analysis based on whether a color is already dark, and
therefore uses less GCR to get darker. It is recommended to leave this button always on. If you
encounter some dithering from color-to-dark (e.g. if the black ink starts too early), it might help
to switch the function off, although it might make the printer gamut less linear.

Calibration Wizard 8.2.0 hueman V2 - Black Generation – 40/58

 • Shadow dot gain: A dot gain can be added to improve overprinting of colors, also in darker
areas. An insufficient saturation in dark areas is sometimes caused by an intermediate ink limit
behavior, which causes a bump between absolute ink limit (2-mix-colors) and the relative ink limit
set in the RIP (e.g. 240%). A regular dot gain is usually applied to all colors, but from the CIELab
point of view, the linearity is not given anymore. The Shadow dot gain parameter adds a dot gain
only where is it required; in already saturated colors, to counteract the bump effect. The default
value of 15% is a good balance between improving the bump effect and laying down too much
ink, but mainly depends on how heavy the colors have been linearized.
The Early black improves the gradient and linearity from dark-saturated to dark-unsaturated
color, affecting the black ink directly in normal cases, and should be switched on by default.
Switch it off only if you experience strong jumps in dark-unsaturated areas from the black ink or
a rich black combination.

Printer Profiling
This is the step in the calibration process where the ICC profile is generated. After completing the
hueman v2 black generation window, you will get to the printer profiling one, when hitting next.

 Remember that this option is only activated if you have purchased the license to generate ICC
profiles, so, if you don't have it, the Measure and Generated buttons won't be available, and
related options like Smoothing.

Calibration Wizard 8.2.0 Printer Profiling – 42/58

Target File
In order to print a target for your
spectrophotometer, select from the drop-down
list the appropriate target: Small/Medium/Large/
Very large/Custom. For a high-quality profile, you
should print at least 1500 patches for paper
prints, and 2250 for textile prints.

Print
After you have selected the right target, use the
Print… button to print out the target file on your
media. The Page selector opens to select the type
of the target file. Click Ok to continue.

Print configuration dialog opens. Configure the

Print of the target first.

Measurement
You are now ready to measure the target. As with all charts, you have to steam and wash it, or have it
dry for a couple of minutes (paper printing). Make sure you select the same target file that you have
previously printed, and press on the button to open the measurement dialog and to
connect with the spectrophotometer.

Calibration Wizard 8.2.0 Printer Profiling – 43/58

 Then start reading the lines carefully and slowly
according to given specifications. Measure 2
targets to make an average between the
measurement. This will improve the quality in the
profile while remove interruption in the
measurement.

Be sure to read slowly regular the lines, one by

one. When you finish reading the target, hit Ok to
forward.

In case of measurements errors the red squares

around the patches showing possible errors
warnings. With the slider of Error tolerance the
warnings can be filtered.

Pressing right-click mouse on the red square it opens the Spectrum visor
showing the spectral curve of the selected chart patch.

Calibration Wizard 8.2.0 Printer Profiling – 44/58

 When the measurement is completed you will be
asked to generate the profile with internal
application profiler. Gradient Few will be taken by
default when allowing the wizard to generate the
profile after measurements are completed. More
info about other smoothing gradients are
described in next section.

Smoothing
With this option you can specify a certain amount to smooth out error measurements, although much
of it is avoided by choosing to do three measurements of each test file, as the CW8 has newly
incorporated. Broadly speaking, the more you smooth a profile the less precise this will be, so
smoothing should apply only if the global precision of an ICC profile is maintained, and the most
important aim is to achieve smoother gradients in printing. The options for smoothing are, in general
terms:
None : should be used when measurements are good, as with paper
Few : can be selected for stable readings on dense, low-structured textiles
Normal : would apply with unstable measurements on structured textiles
High : is only to be selected for extremely structured textiles, like towels. This gradient is not
recommended to use, as it implies heavy smoothing.

Profiling presets
For the standard ink setup there are 3 presets
available:
• Default RGB profile
• Color matching RGB profile
• Color matching RGB profile (OBA)

Default RGB profile is used in standard print flow, which relates to Perceptual rendering intent. It
compresses the total gamut from one color space into the gamut of color space when one or more
colors in the original image is out of the gamut of the destination color space. This preserves the visual
relationship between colors by shrinking the entire color space and shifting all colors, including those
that were in gamut.

Color matching RGB profile is used in printers workflows, which relates to Saturation rendering intent.
It reproduces the original image color saturation when converting into the target color space. In this
approach, the relative saturation of colors is maintained from gamut to gamut. Color matching RGB
profile (OBA) is built as the Color matching RGB profile but is supported for Optical Brightener Agent
(OBA).

Calibration Wizard 8.2.0 Printer Profiling – 45/58

 Using fluorescent inks setup the corresponding
presets becomes available, with or without OBA.

Generate profile
Before starting generation of profile, you will be
asked to save the icc profile into location of the
printer scheme folder using the same name. It is
recommended to give the same name to the
profile that you gave to the complete calibration,
to avoid confusion. You can also specify where
you'd like to save the generated profile; typically,
in the desktop since you can easily distribute if
from there, or within your profile folder. During
the profile generation the generating process is
visible in the profile log. When 100% of the
process is reached, the icc profile generation was
successful.

Profiles list
Once you have your ICC profile generated, this will
appear on the profile list automatically. Or else
you can select another profiles or import profiles
with the "+" button next to the list. Click on the
button and select the location of the profile (e.g.
Desktop). CW8 will then show a list of profiles that
have been detected in the specified folder and
that are compatible with ICC RGB printer profiles.
Now you can select the profile from the drop-
down list.

Calibration Test Print
We have reached the last window of the Calibration when hitting done after the printer profiling. A test
workflow to verify the quality of the calibration using print parameters and files.

Calibration Wizard 8.2.0 Calibration Test Print – 48/58

Workflow
In the upper part of the window, the Workflow options can be used to define some initial parameters.

Rendering Intent offers two methods: the default

mode, which uses the Perceptual mode and thus
provides more realistic colors, and Saturation,
which uses saturated colors and renders brighter
colors.

Mirroring is usually used for transfer. In this window you have the option of applying Full page
mirroring, which will obviously change the whole page.

Input defaults displays a new window. By default,

Input ICC profiles is not activated, as changing
them may completely change the colors you will
print. The same goes for Proofing. This consists of
obtaining from our printer the results which
would be obtained using another printing system.
Please refer to point 5.2 of neoStampa's manual
to understand the main rendering intents offered.

Also, beware in the above window if you are going to use the Design orientation and mirroring options,
because if you have already selected Full page mirroring in the previous window, these buttons will now
double the effect. With Color adjustments you can use Brightness/Contrast/Saturation filters to apply to
each job document and its opened images.

 Full page mirroring and Input defaults provide the same setting options given in the Printer
scheme manager, in the Advanced tap.

Calibration Wizard 8.2.0 Calibration Test Print – 49/58

Test print
With the Test print option you are able to choose
a test image and check the profile and print
quality. With the "+" button you will choose the
file you need from your computer. Once selected,
this will be included in the drop-down list.To test
the image you like, just press Print… button.

Comments
An empty area to include Comments belonging to
the calibration is available. Those comments will
be seen when you open the Advanced tap of the
Printer scheme manager.

Finish
The last step of the Calibration Wizard will be to Finish… the calibration by clicking on this button.

You will be prompted to give it a final name to complete the

calibration. You have the possibility to group the schemes. All you need
to do is to add "@" in the name, where the name should be split to use
the information as sub group.

Printer Consistency Test
This function is new in respect to the Calibration wizard 7. This is a very useful tool to check if the
profiles that you have already generated still keep the same quality and the printer consistency is
stabile.
The main purpose of re-profiling with Calibration Wizard 8.2 is to establish a quality control of the
master calibration. Specially after a period of time after the calibration some differences of unseasonal
or other conditions can appear. Also when paper roles of same types are changed or/and inks of the
same types are re-filled in the machine.
Re-profiling is based on the full calibration process and will always match the values back to the
measured values of the master calibration profile, which is the done as the first printer calibration with
its inks and media. The master profile won't be changed and the tool will generate a new profile.

 That following explained action tool is useful to recheck the profile and printer consistency after
some period of time uses. If you need to change inks, or media, this re-profiling is not the tool
to do as you should make a full new calibration. Nevertheless, to reach the best result of your
profile, the absolute recommendation is to start a new calibration. Be aware of DeltaE changes
in the white of the media, which means that some changes appears on the fabric or paper
between re-profiling and the first calibration. The important value is the DeltaE of average,
which is acceptable between 3 and 4 . With extremely high values we recommend to make a
new full calibration.

Before starting
As in the full calibration process, we recommend to pay attention on following points.
1. Pay attention in nozzle print quality in your digital machine. Make sure to do the nozzle check
before you start a new calibration.
2. Re-profiling test chart must be printed UNI - directional, the same condition as done with the first
calibration.
3. Printing always in same direction (horizontal OR vertical) to secure the same printing
environment during the calibration process and making an average in neoStampa 8.2, which
means reading two target charts.

Calibration Wizard 8.2.0 Printer Consistency Test – 52/58

Re-profiling Printer
In the first window of Calibration Wizard the third action is to select. Search for the scheme in the drop-
down list, and hit Next, on the lower bar. You will access the last profiling window of the calibration.

Calibration Wizard 8.2.0 Printer Consistency Test – 53/58

 You will access the last profiling window of the
calibration. This action detects automatically the
reference of profile or type of target which was
used in the full calibration (2250 patches) in the
first master calibration.

Since this process is just a check, the profile that

will be generated is based on 152 patches which
is the calculation for target with 2250 to match
the best recheck values.

Click on Print… to proceed. As in all Prints in the

Wizard, you will be able to configure it before.

Calibration Wizard 8.2.0 Printer Consistency Test – 54/58

 Proceed to print the target and measure it, the
same process of printing and measurement as in
the full calibration process, using 2
measurements to average the values.

When the reading is done, you will get the

compared DeltaE results to the initial calibration
profile .

If you wish to see all the

target comparison results
in values, click on the View
all results … to see where
the colors with high DeltaE
values, with option to
export the results with
Export results … button.

If the DeltaE results are higher than desired, in the

next step you can generate with pressing
Generate… a new profile.

Calibration Wizard 8.2.0 Printer Consistency Test – 55/58

 Calibration Wizard will locate the printer scheme
folder to allow to save the new profile and is
modifying the file name with adding the _ reprof0
to differentiate from the master profile.

The generating of the new ICC will start

automatically until is proceeded to 100% of
generation process.

In the last step of re-profiling your printer, you are

available to embed the new profile into the
printer scheme.

Also creating a new printing scheme using the new profile is given as
possibility. This new scheme will use all necessary embedded files, as
the linearisation curve. It is a copy of the master calibration using the
new profile and new scheme name.

Calibration Wizard 8.2.0 Printer Consistency Test – 56/58

 You have finalized the re-profiling process in
Calibration Wizard 8.2. The printer using the new
profile is ready to use, until the next re-profiling is
pending. Back in neoStampa 8.2, when opening
the printer scheme, you can see the embedded
re-profilied ICC in Color under Color Management.

Calibration Schemes Backup
At the bottom of the Printer Scheme manager there is the Backup button. This is to save any changes
made in the scheme.

Any time you make changes on a finished scheme they will be stored in
a new zip file. This is a very useful function as you may want to use a
previous version of the scheme. The first version is saved as a _zip0. cpz
file, and the following ones will continue numeration.

When you browse through the schemes list in

your computer, you will be able to see all the
versions from a scheme.

Whenever you want to use any of those copies,

press Restore and selected it from the given list.
