Descreen - Canon N1220U User Manual

Descreen

Moiré patterns occasionally appear when items printed at high resolutions are
scanned. To reduce this phenomenon, scan photographs and other high-resolution
prints with the Descreen function enabled. Shut it off to scan lower resolution
items, such as newspapers, books and magazine text. The default setting is "off."
Caution
• The Descreen function cannot be switched on for scanning resolutions
higher than 601 dpi.
• The previous setting is enabled for the Descreen function when Plug-in
Module CS-U is opened by a software application operating in the
windowless mode.
Operating Procedures
Open the [Image] menu and select [Descreen].
A check mark will appear beside the Descreen option in the menu when this function is
set to On. To set it to Off, reselect it. The check mark will disappear.
