Adobe InDesign CMYK work flow

 

Who should use this work flow?

A pre-separated CMYK work flow is recommended for those who want the confidence of making CMYK separations for a known printing process and media type. Scanners and digital cameras typically deliver color to the computer in RGB (red, green, blue) format. Converting that original color into the colors needed for a printing process requires knowledge of the specific device and its media type, as CMYK conversion are printer-paper specific.

If you know the printing device, its colorants and media type, it is safe to convert files to CMYK early in production using either an ICC output (printer) profile, or another means (Photoshop separation tables, for example) to get CMYK from the original color files.

See Converting RGB to CMYK in Adobe Photoshop for more information.
