Descreen
Descreen allows you to remove moiré patterns in images.
A moiré is an undesirable pattern in printing that results from
incorrect screen angles of overprinting halftones. Moirés
usually result when you scan images taken directly from a
magazine (instead of scanning a continuous glossy photo-
graphic original or a transparency).

To use Descreen:
1 Click on the More Options tool in the Settings window.
2 When the More Option screen comes up, click on the
Descreen box and select your descreen option. The
option you select will depend on the dot quality of the
original.
• Choose Newspaper if the original image has a coarse
dot pattern (like images in a newspaper).
• Choose Magazine for images with a finer dot pattern.
• Choose Art Magazine for images with near-photo-
graphic quality with a very tight dot pattern.
• Choose Custom to set your own descreen options.
A check appears next to the descreen option that is
enabled.
Because of the nature of this filter, scans may take longer
if you use the Descreen feature.
