Reply To: Color Conversion from InDesign

Hi Jeffrey, yes, InDesign can do the conversion of RGB to CMYK. By default, CMYK images will be passed through unaffected. Grayscale images that are RGB will be treated as though they were color, so they will convert to a four-color CMYK. Grayscale is trickier… InDesign will normally just pass them through unaffected, which may be what you want.

If you have access to Lynda.com/LinkedIn Learning, I encourage you to take a look at my course “InDesign Color Management” which should give a pretty fast overview of the various factors.
