1. Print this plot in your Substrate & Printmode. Print at max ressolution & Vertically and Scale 1:1.
Patterns to picture for Remote Support
P/N - Printer SN: Printmode Room Temp[C] RH [%]
2. Check Issues first in Primary Patterns (1, 2, 3, 4, 5, 6).
3. Compare patterns and Fix Issues according with User Manual.
4. For Remote Support, picture at high ressolution patterns failed.
1 PH ALIGNMENT color to color PH ALIGNMENT BIDIRECTIONA or SUBSTRATE THICKNESS SUBSTRATE ADVANCE COALESCENCE AND GRAIN
Check PH Alignment between colors: Align Missaligned Colors.
2 Check Round Center Spots & Vertical Lines are narrow & Sharp
3 Check horizontal lines are thin & well defined
4 Check uniform color blocks without severe grain or coalescences. IMAGES for IQ Reference with Real User Images
Also Check PH Alignment, Media THickness, or Media Advance Adjust / Calibrate media advance factor. Adjust ink levels or drying conditions. ALso check PH Alignment and Substrate Advance performance Compare vs Patterns defects to have a real assesment of the Severity

UNIFORMITY
Check Areafill uniformity
(1) Check Vertical Bands along Scan Axis
Color horizontal Bands may require PH recover, Alignment, or adjust special inks levels (Optimizer, Overcoats generates gloss banding, etc). / Vertical banding, or pattern may require adjust media seetings to keep media flat, and avoid waves or wrinkles. / For strange color patterns check also Drying airflows and ink levels.
Line Dimension 500mm
10 SCAN AXIS UNIFORMITY LINES & COLOR
Check Lines Quality Thickness along Scan Axis. (1) Ensure Sustrate flattness (No Curl or Wrinkles) . Adjust Media / Printer Settings. / Check Color Consistency along Scan Axis. In case of difference in colors side to side, (1) check media Curl. (2)Also check PH Health. / Check Drying uniformity along Scan Axis . IF not uniform, check drying elements or material local issus
