What should I do when KDP lists specific PDF pages with errors?
Short answer: When KDP lists specific PDF pages, look for a pattern before editing everything. Even-numbered pages may be backing pages, repeated page numbers may point to inserted blanks, and scattered pages may have source image or bleed issues. Fix the pattern, rebuild the PDF, and check it again in KDP Previewer.
Why this causes KDP problems
KDP error messages often name page numbers instead of explaining the whole workflow mistake. In image-based interiors, those page numbers can reveal what went wrong: every second page may be a backing page, the first few pages may be front matter, and late-page clusters may be images exported from a different source.
Recommended workflow
- Write down every page number KDP reports.
- Check whether the pages are artwork pages, backing pages, blanks, or front matter.
- Confirm whether those pages use the same trim size and bleed mode as the rest of the PDF.
- For bleed interiors, check for white borders and backgrounds that stop at the trim line.
- Rebuild the PDF after fixing the repeated pattern.
- Upload the revised PDF to KDP Previewer before publishing.
Where Book Interior Kit fits
Book Interior Kit helps because it builds artwork pages and optional backing pages from one selected KDP setup. That makes it easier to avoid accidental mixed page sizes and easier to reproduce a corrected PDF.
What to check before publishing
- The reported KDP pages follow a known pattern.
- All inserted pages use the same selected page setup.
- Full-bleed pages extend to the bleed edge.
- Non-bleed content stays safely inside the margins.
- The final PDF is reviewed in KDP Previewer.
