Raster method, e.g. for multicolor printing, involves analyzing print image in color separations for printing colors, and using amplitude modulated rastering for one separation and frequency modulated rastering for other separations

摘要

The method involves analyzing a print image to be printed in color separations, such as cyan, magenta and yellow, for printing colors involved in printing, and allowing each of the color separations to undergo a rastering. An amplitude modulated rastering is used for one of the color separations of the print image, and a frequency modulated rastering is used for other color separations.
