Introduction

Descreen plug-in is used for descreening images that have been scanned from printed sources (such as newspapers, magazines, books, postcards, etc). Descreening prevents moiré patterns.

Unlike most scanners which apply blurring to remove a screen, the plug-in Descreen uses the Fourier transform to automatically find parameters of a screen and precisely removes it. Due to that the plug-in preserves more image details. There is no need to scan images at different angles and to resort to other time-consuming tricks. You need just provide the plug-in with a hi-resolution scan, usually 600...1200 pixels/inch.
