Why RGB PDFs cause print surprises
RGB colors are designed for screens. Print workflows need predictable separations and output intent, so colors should be converted with a known CMYK profile such as SWOP, GRACoL, or FOGRA.
PDF to CMYK conversion for print-ready exports
PDF to CMYK conversion should use an ICC-aware print workflow, not a visual-only color filter. Trim Proof targets CMYK output through Ghostscript and validates the final file before download.

How Trim Proof handles color
The system stores print-profile choices in the LayoutSpec and routes final PDF output through the deterministic prepress stage. The default profile is configurable and should match the printer or market.
Common questions
Is CMYK conversion the same for every printer?
No. The best profile depends on the printer, stock, region, and press workflow. Trim Proof keeps the profile explicit.
