Wire-O, spiral and GBC
Wire-O, spiral and GBC are types of mechanical binding in which pages and cover are held together by a metal or plastic coil. Though more expensive than wire stitching, mechanical bindings allow their contents to open wide and lie perfectly flat.
Advantages: Lies flat; pages can be removed without deletion; adaptable to different paper types; offers singe-sheet insertion for flexible page count; bindings come in a wide variety of colors.
Disadvantages: Greater expense; can detract from project aesthetics.
Many annual reports and larger catalogs use this binding method. Here, pages are assembled in groups or signatures, and bound together with flexible adhesive, then covered. Perfect binding accommodates books approximately 1/8-inch to 2-inch in thickness.
Advantages: Accommodates greater number of pages and higher page weights than saddle-stitch; accommodates multiple sheet weights and sizes; allows intermix of stocks; provides clean finished edge.
Disadvantages: After pages are collected into signatures, the binding edge is ground off to improve adhesion. That, along with a three-knife trim, takes approximately 1/8-inch from each side of a document. Does not lie flat; crossover images and type may be partially hidden by the binding edge.
Case or edition binding
Case, or edition binding is the conventional method used in most hardcover books. Sheets are folded into 16- or 32-page signatures, pasted with end leaves and sewn together. This process culminates in a hard cover, which ensures durability for years to come.
Advantages: Provides perfect crossover of images from page to page; archival quality.
Disadvantage: Most expensive binding method.
Saddle wire stitch
The saddle wire stitch allows the book to lie flat for reading ease. It can be bound with either a self-cover, or a separate cover. It is the most economical solution.
Advantages: The saddle wire stitch allows the book to lie flat for reading ease. It can be bound with either a self-cover, or a separate cover. It is the most economical.
Disadvantage: The page count must be divisible by four. This restricts the number of pages. It is the least flexible of all binding options.
