Perfect Binding and Burst Binding

Perfect binding is the process of glueing the inner pages edges into a combined spine within the cover. It is suitable for light usage, and has the disadvantage that single pages may fall out with a long time with heavy use. It's cost effective and suitable for most book print jobs. Burst binding, on the other hand, has notches or perforations in the spine which allows better penetration by the glue. Another significant advantage is that the spine edge is not milled like the above perfect binding, leaving the signatures intact and reducing the possibility of pages tearing out. That means burst bound book have better strength and durability than perfect bound book.
Perfect binding and burst binding both present well, but are not suitable for heavy wear usages. They are useful for quality periodicals, school yearbooks, light use catalogues and other types of general usage publications. They are normally used for publications of 64 pages or more.
