How do I convert the spot or RGB colours in my InDesign or Illustrator file into CMYK?
- Open your artwork in Illustrator or InDesign.
- Open the Swatches panel, which lists all the colours used in your artwork.
- Find for swatches that are set to spot colour: these are marked by a spot in a box to the right of the swatch.
- Double click on the relevant swatches, and choose Process from the drop- down menu, then click CMYK.
