Paperback Print File Preflight
What It Means
Paperback print preflight is a structured QA process used to verify that final PDFs are ready for submission to a print platform. It checks geometry, embedded resources, and export consistency before upload.
Why It Matters
Preflight reduces the chance of avoidable upload failures by catching trim, bleed, margin, font, and image problems before preview. It also gives teams one repeatable checkpoint at the end of production.
Step 1 — Verify Page Geometry
Check:
- trim size
- bleed
- margins
Step 2 — Verify Resources
Check:
- fonts embedded
- images 300 DPI
Step 3 — Final Upload Validation
Run a full preflight check before submission.
Example
Assume a paperback interior and cover are both finalized after late proofreading changes. Running preflight confirms that page size, bleed, fonts, and image resolution still match the latest exported files before upload.
Common Mistakes
- Running preflight before exports are final.
- Checking only one file instead of both interior and cover.
- Skipping image and font verification.
- Not recording which file version passed checks.

FAQ
Should preflight happen before or after preview?
Before preview. It helps catch file-level problems early.
Does preflight include both cover and interior?
Yes. Both files should be checked together.
Is preflight only for KDP?
No. The same workflow is useful across paperback print platforms.
