Types of bindings used for printed catalogs.

Printed catalogs use one of the six different forms of standard stitching for binding.

Below is a brief description of each type of binding.

Perfect binding: This process glues the outer edge of the signatures, creating a squared off back.
Saddle-stitch binding: This method uses either staples or stitches to bind the catalog at the fold, then attached to a flexible cover.
Side-stitch binding: This method is similar to Saddle-stitch binding in that it uses either staples or stitches. However, with this method, the signatures are bound on the side instead of the fold and attached to a flexible cover.
Case binding: This is when the signatures of the book or catalog are glued or sewn together then the first and last pages are glued to a hard cover.
Plastic Comb binding: This method uses a plastic comb, which is inserted through
pre-punched holes in the paper.
Three-ring binding: This is also referred to as notebook binding, and is when three holes that are spaced apart are punched into the pages, which are then placed into a binder.
