What this issue means
Front and back covers submitted as separate pages cannot represent the expected back-spine-front geometry. The checker reports page count before evaluating full-wrap size.
What BookPreflight checks
- Cover PDF page count
- Orientation and full-wrap dimensions
- Back, spine and front placement on the single page
How to correct the source file
- 1
Create one artboard at the complete template size.
- 2
Place back cover, spine and front cover from left to right as required.
- 3
Export only that artboard as a one-page PDF.
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.
