- Confirm full-wrap width includes back, spine, front, and bleed
- Inspect barcode and safe zones
Repair
- Resize the cover canvas from the current template
- Reposition spine text and safe-zone content
- Re-export without printer marks
Escalate: Escalate when page count is still changing or the original layered cover file is unavailable.
