PDF output settings now support converting RGB colors to CMYK during export. Templates often contain RGB content — photos from a DAM, or colors defined for screen — and this new option brings that content into your print-ready color space, as a complementary step to the CMYK conversion:

  • Enable it in your PDF output setting — switch on Convert RGB colors to CMYK colors in the Color management section. The switch becomes available once the intended and target CMYK profiles are set, since RGB colors convert to the same target CMYK profile — see the PDF output settings guide.
  • Pick an RGB source profile — RGB colors with an embedded profile are converted using that profile; for unmanaged RGB colors, choose the assumed source profile (such as sRGB IEC61966-2.1 or Adobe RGB (1998)) from the dropdown that appears.

For Environment API integrations, postProcessing.colorTransformation accepts two new properties: convertRGBColors (optional, default false) and intendedRGBIccProfile (required when convertRGBColors is true):

{
  "postProcessing": {
    "colorTransformation": {
      "intendedIccProfile": "ISO Coated v2 (ECI)",
      "destinationIccProfile": "Coated GRACoL 2006 (ISO 12647-2:2004)",
      "convertRGBColors": true,
      "intendedRGBIccProfile": "sRGB IEC61966-2.1"
    }
  }
}
