Descreening

The process of removing the screen structure from images. This is done by first scanning screened originals out of focus. The image is then sharpened up using image processing software on the computer. An image can also be directly descreened by processing it with software which specifically filters out the regular screen structure. The two methods serve, among other things, to prevent the moir? effects produced when two screens are overlaid and do not coincide exactly.
