Saving files in Photoshop DCS format (Photoshop)

DCS (Desktop Color Separations) format is a version of EPS that lets you save color separations of CMYK or multichannel files. For more information about the Photoshop DCS format, see Photoshop DCS 1.0 and 2.0 (Photoshop).

To save a file in Photoshop DCS format:

1. Choose File > Save As and choose Photoshop DCS 1.0 or Photoshop DCS 2.0 from the Format menu.
2. In the DCS Format dialog box, select the options you want, and click OK.

The dialog box includes all the options available for Photoshop EPS files. For more information, see Saving files in Photoshop EPS format (Photoshop). Additionally, the DCS menu gives you the option of creating a 72-ppi composite file that can be placed in a page layout application or used to proof the image:

• DCS 1.0 format creates one file for each color channel in the CMYK image. You can also create a fifth file: a grayscale or color composite. To view the composite file, you must keep all five files in the same folder.
• DCS 2.0 format retains spot-color channels in the image. You can save the color channels as multiple files (as for DCS 1.0) or as a single file. The single-file option saves disk space. You can also include a grayscale or color composite.
