PERfection offers seven filter functions which con-
tribute dramatically to increased productivity in the
digital workflow:
• AutoClean
• DotClean
• Dot Correction

• Registration
• Rotation

4.2    AutoClean
AutoClean works as a filter which automatically re-
moves dust and scratches from areas with non-
screened areas, e.g. text areas.
AutoClean example :
1. Open the image (and pick a selection tool, if
   you wish to focus on a specific area).
The sample image shows a typical line scan con-            Provided you have balanced the parameters correctly,
sisting of text, spots and speckles.                       AutoClean will clean up your image to perfection.

                                 active when at least two successive bytes are identical.
                                 For drawings it can result in compression ratios as high as 10:1, in text 3:1 to 5:1, whereas
                                 it is useless for pre-screened originals. PackBits requires very little computing power.
                                 PackBits should only be used for drawings and text - not for prescreened originals.
