Perfect Binding is the type of binding used on paperback books, catalogs, magazines, and inexpensive products such as manuals and workbooks. The cover utilized for this type of binding is glued to the signatures (large sheets printed with a multiple of four pages, which are then folded to make a book) at the spine. A type of flexible adhesive or hot glue is utilized, and the sides of the papers that are attached to the spine are rough-cut so that they will absorb the glue and stick to the spine. The glue attaches the signatures to the cover of the product, holding the individual pieces in place. The remaining 3 unbound sides of the sheets of papers are face trimmed so that any folds will be removed and the individual pieces of paper, separated. Perfect binding can be used for thicker publications, since it can hold more pages than saddle stitching. We provide perfect binding for our booklets and catalogs with 48 pages or more
Saddle Stitch Binding, also known as stitched binding, is a process in which the signatures (or the sheets with several pages printed on them) are stapled through the spine, or the saddle. Loose sheets of paper are first folded and inserted within each other, and the fold becomes the spine of the product, where it will be binded. The product is then stapled through the spine, holding the sheets of paper in place. Stitched binding is used for little booklets, newsletters, and magazines, and is essentially used for products that do not have a high volumes of pages. We provide saddle stitching for booklets and catalogs for up to 96 pages plus cover.
