Descreen
Moiré patterns occasionally appear when items printed at low resolutions are scanned.
Moiré patterns are dot-like patterns that interfere with processing images for
professional use and are usually caused by poor dithering resulting from scanning
images from newspapers, books, magazines, etc. To reduce this phenomenon, scan
photographs and other low-resolution prints with the descreen activated. Shut it off to
scan higher resolution items. The default setting is “off”.
Caution
• The Descreen cannot be switched on for scanning resolutions higher than 601
dpi.
• The previous setting is enabled for the Descreen when Plug-in Module CS-U is
opened by a software application operating in the windowless mode.
Procedure
Open the [Image] menu and select [Descreen].
