Online PDF prepress tools for print-ready proofs
Short answer
Online PDF prepress tools should help a print file move from a screen preview to a file a printer can inspect. Trim Proof focuses on the core production checks: CMYK-oriented output, bleed and trim geometry, crop marks, embedded vector text, image DPI, PDF/X status, and a visible preflight report.
Use this page when you need one place to understand the print-production checks behind a PDF before sending it to a printer or client.

- 5Run preflight and review the report before export
Why prepress tools matter
A PDF can look finished on screen and still be risky for print. Prepress checks make the hidden file structure visible: page boxes, font embedding, output intent, image resolution, and mark placement.
Where Trim Proof fits
Trim Proof is built for generated print proofs, not arbitrary repair of every existing PDF. The product creates a structured proof from a brief, then checks the output before the paid production download.

Common questions
Is Trim Proof a full replacement for every prepress tool?
No. Trim Proof focuses on generated proof workflows for starter print products. It is useful when you need deterministic print geometry and preflight evidence around a new proof.
Can online prepress checks guarantee printer acceptance?
No. Printers can have vendor-specific requirements. Preflight reduces avoidable file problems, but final acceptance depends on the printer's specifications.
