DCS stands for Desktop Colour Separation. It is a file format that is based on the EPS file format. In fact, you could regard DCS files as a collection of EPS files. DCS files are mainly used to exchange bitmap images between pre-press applications. There are two types of DCS file; v1.0 and v2.0:
A DCS 1 file is composed of 5 separate files. The main file has the extension .eps while the 4 other files have an extension that marks the colour data they contain. The main file does not contain any actual image data but only a preview image and pointers to the other 4 corresponding high resolution colour files.
DCS 2 files add the option to create single files. These are not composite files, simply the same collection of file data merged into one larger file. In addition, DCS 2 creates the ability to specify further plate colours in addition to CMYK. This makes DCS 2 the ideal format for hexachrome images that contain six colours.
