Book / Offset Printing
Book:
A book is a medium for recording information in the form of writing or images, typically composed of many pages. Usually made of paper bound together and protected by a cover.
Perfect Bound
An adhesive form of binding. Signatures that are folded will have a section of spine cut off with the back edge rougheed, glue will then be applied and the cover attached.
Thread Sewn
A paper or board book cover that is attached to a sewn book block by gluing the spine and then trimmed to final size. In producing the sewn book block, after gathering of signatures, the sewing machine inserts threads through the spine of each section and then uses further thread to join the sections to each other to form the book block.
