Is Your Project in a Bind?
Today’s multifunction printers can do may things, including binding printed items into a finished item. While there are multiple ways to bind your documents into a finished product, including spiral or wire-o binding, the two most common are saddle stitching and perfect binding. Undoubtedly, you’ve encountered both of them before.
Saddle stitching is a binding method that holds folded sheets of paper together with wire staples passed through the crease. Each sheet is printed at twice the width of the finished product and is printed with one page on the left and one on the right and (presumably) on the front and back. If the finished product is to be 8.5 inches by 11 inches, then each printed page will be 11 inches by 17 inches before it is folded and stapled.
Once printed, the collated sheets are draped over a piece of equipment that resembles a saddle (hence the term “saddle stitching”), and the staples are passed from the outer spine and fastened at the book or brochure’s center. This is the most common type of bindery used for small booklets, catalogs, or magazines. Larger items won’t lie flat across the saddle and may also be too thick to staple.
One drawback to saddle stitching is that the more pages you add, the more you’ll notice that the inside (or middle) pages stick out further than the outside pages after stitching. This is commonly called creep and happens because the paper along the folded edge takes up space and “pushes out” the inside pages. The finished booklet will then need to be trimmed in order for it to look decent.
Perfect binding is what we see used most often to bind larger items such as books together. Instead of staples, the pages are glued together at the spine, and the cover is wrapped around them.
Perfect binding is often a slower and more expensive process than saddle stitching, but it results in a very professional-looking finished piece with a spine that can also be printed with text and/or graphics. This type of bindery is durable, and it allows even very thick publications to lie flat when closed (unlike saddle stitching).
Regardless of which type of binding you decide to use for your finished product, it’s important to consider this during the design phase. Saddle stitching, especially, will require you to design around the fold that happens as part of the stitching process. You don’t want to end up with any print buried too deep in the fold of the booklet’s spine or too near an edge that may be trimmed. Perfect binding does not require as much space around the inside edge, and therefor is less of a design constraint.
