Bound to Impress

Bound to Impress Different binding techniques have different advantages—and often different layout requirements. Saddle stitching is fast and inexpensive. In publications with high page counts, the thickness of the paper can result in page creep, which pushes type and images on the inner pages closer to the outer, trimmed edge. Ring, plastic comb, spiral, and double loop wire bindings allow the publication to open flat, but except for ring binding, they cannot be printed on the spines. Inner margins must be wide enough to accommodate the binding, and crossover images will lose much of their impact. Perfect bound publications are held together by a flexible adhesive. They are not as prone to page creep as saddle stitched publications, but text near the gutter can be hard to read. Depending on the weight of the paper, perfect binding requires a minimum of 16 to 20 pages. Screw and post bindings accommodate large numbers of pages or heavy materials, such as wallpaper samples, and allow the contents to be changed easily. Usually found only in hardcover books, sewn case bindings are the most durable and expensive. The use of specialty bindings, including sewn soft cover, side wire stitch and velo bindings, can lengthen production schedules.
