CristalRaster
A process which Agfa have developed to generate a halftone which is free from moiré patterns. The CristalRaster screen, when used with correctly prepared plates and multi-coloured presses, produces printed images which appear to have a continuous tone or photographic quality. A CristalRaster screen can be printed onto film at a bureau and used in the double exposure of pad printing plates. A CristalRaster has a random dot structure while others screens have a pattern in the dot structure.
