Prepress checklist for print-ready PDFs
Short answer
A prepress checklist helps confirm a PDF is ready for print by checking trim and bleed boxes, crop marks, embedded fonts, CMYK-oriented output, image DPI, safe-area placement, PDF/X status, and a preflight report. Trim Proof turns supported starter-product briefs into checked PDF/X proofs, but printer-specific requirements should still be reviewed before production.

What to check before sending a PDF to print
Start with the printer's own specifications, then verify the file structure. The most common checks are trim size, bleed amount, safe-area placement, crop marks, embedded fonts, color workflow, image resolution, PDF/X status, and the final preflight report.
Where Trim Proof fits in the checklist
Trim Proof is built for supported starter products such as flyers, business cards, postcards, and letterhead. It creates the proof from a structured brief, keeps text in a deterministic composition layer, and checks the PDF before a production download.
What still depends on the printer
No checklist can replace the printer's exact requirements. Bleed, marks, preferred PDF/X version, color profile, stock, finishing, and imposition details can vary by vendor, so the final file should be compared against the printer's instructions.

Common questions
What should be on a prepress checklist?
A practical prepress checklist should include trim size, bleed, crop marks, safe-area placement, embedded fonts, CMYK or output-intent handling, image DPI, PDF/X status, and a preflight report.
Can preflight guarantee printer acceptance?
No. Preflight catches many structural print-file issues, but each printer can set its own requirements for color profiles, marks, finishing, stock, and delivery format.
Can Trim Proof check existing PDFs?
Trim Proof is not a universal repair tool for arbitrary existing PDFs. It creates checked PDF/X proofs from structured briefs for supported starter products, then reports the print checks before production export.
