DCS File

Desktop Color Separations (DCS) is the enhanced EPS file format introduced by Quark, Inc. DCS files stores CMYK (Cyan, Magenta, Yellow, Black) image separated into 5 sub-files: main CMYK image and four files corresponding to individual color channels. DCS files are used in publishing to save images in a ready for printing format. When printing on a postscript printer DCS files channels could be loaded into a printer without additional processing on a printer side. DCS file format was quite useful when CPUs and printer postscript processing were slow and color separation took significant amount of time. But at this moment color separation could happen really quickly on any professional workstation which makes DCS files mostly irrelevant.
