CMYK Colour Space Conversion
This option converts the PDF from RGB colour space to CMYK colour space, which is optimized for professional printing. This process:
- Converts colours to CMYK (Cyan, Magenta, Yellow, Black) colour model used by professional printers
- Optimizes the PDF for print production with prepress settings
- May result in slight colour changes as CMYK has a smaller colour gamut than RGB
