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 halftone. Moiré usually result when you scan images

taken directly from a magazine (instead of scanning a continuous glossy

photographic original or a transparency).

To use Descreen:

1. Click on the Descreen pop-up menu.

2. When the Descreen menu comes up, select the screen for your needs.

• Choose Newspaper (85 lpi) if the original image has a coarse dot

pattern (like images in a newspaper).

• Choose Magazine (150 lpi) for images with a finer dot pattern.

• Choose Art Magazine (175 lpi) for images with near-photographic

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.

Clicking the “Add to Menu...” brings up a dialog box for your saving

the descreen as a name for future retrieval.
