The Influence of Ink Sequence on Color Gamut

A test form was printed on a four-color press in order to examine the influence of two process ink color sequences on the subsequent printed color gamut. It was found that the sequence black, cyan, magenta, yellow produced better trapping of the two-color overlaps. The yellow, magenta, cyan, black sequence produced four-color blacks that were more neutral. A sequence of cyan, magenta, yellow, black is suggested as the normal choice for production work.
