I am scanning a photobook, I have unbinded the book and scanning the pages one by one to my Epson Perfection v600. The problem I ran into is that the pages couldn’t lay completely flat on the bed, the pressure from the cover was not strong enough. It was okay for individual pages as they are not that noticeable but it became a problem when I have pages that needs to be stitch together in Photoshop, I have a hard time aligning them.
I tried putting credit card size cards on top of the paper but they were just way too small to cover the entire page. What other methods can I do?
