Descreen plug-in for Adobe Photoshop

English Русский





















Descreen plug-in filter is used for descreening images that have been scanned from printed sources (such as newspapers, magazines, books, postcards, etc, including halftone films). Descreening prevents moiré patterns and consists of two operations:

  • Screen removing.
  • Reducing a halftone moiré pattern.

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.
