What is Perfect Binding

Perfect binding is the familiar square-spine softcover format used for paperbacks, catalogs, workbooks, and other books with flexible cardstock covers. After the pages and cover are assembled, the other three sides are trimmed to create clean, even edges.

There are two common constructions. Glue-only perfect binding holds individual pages at the spine with adhesive. Sewn perfect binding folds pages into signatures and sews them together before the soft cover is attached. Both have the same familiar paperback appearance, but sewn construction is stronger and works better for books that will be opened often. Our current perfect bound softcover uses sewn signatures.

Perfect Binding FAQ

How many pages are required for perfect binding?

Perfect binding typically requires at least 40 pages to ensure enough thickness for the glue to hold properly. Thinner books may not be secure and separation might occurs at the spine.

Is perfect binding good for frequent-use materials?

Standard perfect binding is best for occasional use or lighter handling, as the glue may weaken over time. For frequent-use items, sewn perfect binding provides added durability and longevity.

What types of covers are used with perfect binding?

Covers are usually printed on thick cardstock, often coated or laminated for added strength and a refined look. Gloss, matte, or soft-touch finishes are commonly used depending on the desired styles.
