The Descreen tool lets you remove moiré patterns in the scan process. Moirés
occur when you scan a screened original (mostly reflective materials, such as
pictures from a newspaper or magazine), and these patterns appear to the naked
eye like a series of cross-hatching lines, as shown in the example below.
Note: To find the exact line screen or lpi, you can also purchase a halftone
screen finder at a professional print shop.
