The process of reproducing full color printed images. The image must be converted to a set of halftone screened negatives which are a series of dots of various sizes. A halftone negative is made for each of the separate color components of the image (cyan, magenta, yellow, black).
These color separations are made into printing plates, one for each color and when printed, the overlapping dots of the color components reproduce a full color image. Also called four-color process printing.
