What is perfect binding?

Perfect binding glues stacked pages to a wraparound cover along a flat spine, producing the clean look of a paperback book or a thick catalog. That flat spine can be printed, which is part of its appeal for larger documents.

• How it works: gathered pages are glued to the inside of a wraparound cover at a square, flat spine.
• Printable spine: the flat edge can carry a title, ideal for shelved catalogs and books.
• Page range: works best above roughly 28 pages, where there is enough bulk to bind.
