In the comic book print world, binding is the process of physically assembling a comic book from an ordered stack of paper sheets that are folded together into sections or sometimes left as a stack of individual sheets. The stack is then bound together along one edge by either staples or a layer of flexible adhesive.
When staples are used for binding a comic book, this is known as saddle stitch binding. A saddle stitched bound comic book is assemble by folding several sheets of paper in half and then binding with staples along one edge of the book.
Perfect binding is a different process. Comic book pages are individual sheets that are then glued into a heavier paper stock to bind the pages to the cover.
The most cost effective way to bind your comic books is saddle stitching. It generally falls within the typical process flow of printing and assembling comic books which means less labor time and a savings on total cost. Perfect binding on the other hand requires an additional step to assembling a comic book and therefore leads to a higher unit cost. The comic book pages are printed and cut as individual pages and then are transferred to secondary process of where the pages are glued into the spine of the cover. This leads to more labor time and therefore more cost to the customer.
There are limitations to saddle stitch binding however. Since staples are a set length, there is a maximum number of pages you can include in a comic book before the staples are no longer feasible to appropriately bind the pages together. At this point, perfect binding for a comic book is required.
