You should upload your inside pages as individual, single-page files — not as spreads.
What’s a spread? A spread is when two pages appear side-by-side, like when you're looking at a book opened to pages 4 and 5. Some design programs show spreads by default, but we need each page saved separately.
Why we need single pages:
Spreads can shift during binding
Important content might be cut off or misaligned
Pages are easier to prep and print when uploaded one at a time
How to name your files:
Use simple names like
page1.pdf,page2.pdf,page3.pdf, and so on
Important exception: The cover should be submitted as a spread — this means:
Page 1: Full outside cover (includes the back cover, spine, and front cover as one file)
Page 2: Full inside cover (includes inside back, inside spine, and inside front)
This format ensures the spine and wrap-around design lines up correctly during binding.
