Reply To: Not printing bleed for a spiral bound book

Anything that goes beyond the page edge will bleed. Problem is the Page Tool only separates them visually not techincally – to my understanding. So in reality you've moved the page but the program thinks they are still in contact, and I think it's still treating it as a normal spread.

For spiral bound work you need facing pages, but you also need to Break Pages From Spine

And Harbs posted a link in the comments to a Script that will do this automagically.
