Clean EPUB for IngramSpark

Job ID: 39808862

Budget: $30 – $250 USD

I already have a text-heavy manuscript that I converted from .odt to EPUB in Calibre. KDP accepted it without complaint, but IngramSpark throws a series of validation errors that I don’t know how to resolve in Calibre’s editor. The file does include embedded fonts, so those need to remain intact and properly referenced while still passing Ingram’s EPUBCheck standards.

What I need from you is a rock-solid EPUB that clears every IngramSpark hurdle—no formatting glitches, no stray CSS warnings, no metadata flags—so I can upload and go live on the first try. Please run your preferred validation tools (EPUBCheck, FlightDeck, etc.), fix whatever is tripping the errors, and return a final file plus the clean validation report.

Deliverables
• Error-free EPUB, fully compatible with IngramSpark
• Brief validation report confirming the pass status

If you’ve uploaded EPub to IngramSpark, successfully, I need your help.
