What Trim Proof checks
- Selected print profile
- CMYK-oriented conversion step
- PDF/X-1a subtype
- Embedded fonts
- Raster image DPI
- Preflight report
Short answer
RGB to CMYK PDF preparation should use an explicit print profile and a preflighted export, not a visual-only color change. Trim Proof keeps the print profile visible in the LayoutSpec and converts final proofs through the deterministic prepress pipeline.
Use this page when screen-first artwork needs a print-oriented PDF workflow before production.
RGB artwork is built for lit screens. Commercial print uses ink and paper, so the final PDF needs a print profile and a CMYK-oriented conversion path.
Trim Proof exposes US Web Coated SWOP, GRACoL2013, and FOGRA39 profile choices so the production intent is explicit instead of hidden in a generic export.
No. Some bright screen colors sit outside common CMYK gamuts, so converted print colors may look different.
Use the profile requested by the printer when available. If no profile is specified, choose the profile that matches the region and press workflow.
