Binding methods

A book layout also speciﬁes the means by which sheets are gathered and bound.

Stitching or stapling ﬁnished pages across a common center fold, or spine, is called

saddle stitch binding, and the stitched pages are called a saddle. Multiple folded sheets

can be stitched into the same saddle as a group. Stacking signatures, grinding the

spines off, and then gluing them together is called perfect binding. You can combine

saddle stitch and perfect binding methods by stacking two or more groups one on top

of another on a common fold line and gluing them together; this is called a nested

saddle.

The binding method you use affects the order in which pages are placed on the sheet;

for example, the page ordering used to perfect bind a book must be different from that

used to saddle stitch the same job. Thus, your layout must specify the method by

which the ﬁnished job will be bound.

The choice of a binding method is determined by the job’s size, complexity, and

budget. Saddle stitch binding is very cost-efﬁcient, but is more suitable for small

booklets than for large jobs. (A rule of thumb is that saddle stitch binding works best

for booklets or brochures with a maximum of 88 pages.) Conversely, perfect binding is

more expensive but more suitable for larger jobs.
