Wire-O and Spiral Binding

Both of these mechanical bindings hold far fewer pages than comb binding. Wire-O is a series of parallel wire loops attached along a wire, while spiral binding is a metal or plastic continuous loop passing through the punched holes in a spiral from the top to the bottom of the book. Neither binding method will accept as many pages as GBC. Also neither provides a printable spine or allows for pages to be added or removed. However, both binding methods allow the product to lie flat.

Plastic Coil Binding

This is just like spiral binding. However, since wire can be crushed, plastic is a resilient alternative. Also, plastic coil bindings come in multiple colors.

GBC Binding

Also called plastic comb binding, this method is good for technical manuals that have a lot of pages and must lie flat. The stack of pages comprising the book is punched with a series of holes along the binding edge through which a plastic comb is inserted. This comb, which curls into a cylinder along the length of the book can provide a screen-printable spine. It can also accommodate numerous pages, and pages can be added or removed as needed.
