After the glue sets, the book is trimmed. Strong thermal glue is applied along the spine and the book cover is wrapped around the block pages to adhere to the glue along the spine. The spine side is trimmed to get rid of the folded edges and made more rough to expose the paper fibers and increase the bonding of the glue.

“Perfect binding” refers to the pages that have been cut out to be the same size allowing them to stack perfectly. The pages are held together using a strong adhesive. The printing method forms a flat printable spine, allowing for a title or information on the spine and the cover is usually made from a heavier weight cardstock paper that is coated or laminated to protect the ink on the cover. It was introduced in the 1920’s and enabled the mass production of inexpensive magazines, directories and paperback books. For this reason, it is also known as softcover binding.

As such and because of the fact that binding decisions are typically based on practical considerations such as page count, number of critical crossovers, bulk and weight of stock, shipping, distribution method and printing quality, it is one of the most overlooked design options – in reality, a binding method can become an integral part of the editorial content of the print product.īefore we have a look at the most common binding techniques, here are some useful definitions to have in mind.
However, within these limitations, there is scope for a variety of design possibilities. The binding method is usually dependent on a book’s physical size and thickness, its functionality and cost.
