KDP error guide
Check where bleed is missing
Find edges where artwork does not extend far enough for the selected bleed mode.
Technically reviewed · September 1, 2026
What this issue means
Bleed is an artwork and page-box relationship, not only an export checkbox. The check distinguishes a no-bleed interior from a full-bleed page and reports the affected edge.
What BookPreflight checks
- BleedBox and trim relationship
- Artwork coverage at outer edges
- Safe placement of text near trim
How to correct the source file
- 1
Extend backgrounds and images beyond trim in the source.
- 2
Keep text and essential details away from the cut edge.
- 3
Export using the same bleed mode selected for the KDP book.
Verify the exported PDF, not the preset name
Keep the editable source and original PDF. Export a new file, run the complete scan again and review every remaining finding. A repair is only labelled safe after loss checks and a full deterministic post-flight.
