Process book formats can take forms such as scrap books, sketchbooks, or binders. They can be perfect bound, spiral bound, saddle stitched or hand bound with Japanese stab or coptic stitch.
Coil binding or spiral binding involves creating holes along the left edge of a booklet’s pages and inserting a metal coil through the holes. This binding allows for a wide variety of sizes and page counts. It also offers the most versatility for the user to lay the pages flat, which is why this is a common binding method for spiral notebooks and journals.
Saddle-stitched binding is the most common and cost-effective form of booklet binding. Booklets bound in this way have folded sheets that are gathered together one inside the other and then stapled through the fold line. This allows the booklet to open up fairly flat, meaning less of your design gets lost in the center binding. However, there is a limitation to this type of binding. Staples can only hold so many pages. Therefore, saddle stitching is best for smaller booklets – if you have more than 32 pages you will have to trim for an even edge. Pages must be added in multiples of 4 due to the fold and size of signature – see imposition placement below.
Perfect binding is widely used in soft- and hard-cover books, and what is you see most often on bookstore shelves. The pages and cover are glued rather than stapled at the spine, and the other three sides of the booklet are then trimmed as needed to give them clean, “perfect” edges. Unlike saddle-stitched booklets, perfect-bound booklets often have heavier covers than interior pages to provide durability and improve appearance. Aside from author novels, perfect binding is widely used by businesses for annual reports, manuals, catalogs and thicker product brochures. Unlike saddle stitching, perfect binding allows for an unlimited number of pages because the spine can be adjusted to fit. If you opt for perfect binding, remember to add a little extra space around your center margins, especially if your booklet has a lot of pages. Perfect binding doesn’t accommodate flat pages, so you’ll lose any text or design you place directly in the center fold.
