ABSTRACT:
A hybrid system for digitally screening black and white and/or color images using a number of imaging techniques is disclosed. Cyan, yellow, magenta and black color separation may be processed according to the same or different methods according to gray levels or other factors, in order to optimize output print quality. A hybrid ordered matrix dot rendering system may be employed in part as an optimized screen technique in a variety of circumstances
