Perfect book binding is also called adhesive binding or softback binding. The perfect binding machinery applies the paper cover to the glued book-block, squares it off, and trims the three other sides to make the final book. Perfect binding is the process of applying glue to the spine of a book and applying a cover.Note that the most important part of the process is the "grinding unit"— this makes the difference between a good commercial perfect bind and the POD type binders.
The perfect binding technique is fairly expensive bookbinding, most self-publishers use it, and almost any book binding company is equipped for this technique. Stores like this binding because they can display the book spine-out, saving them valuable shelf space. Perfect binding works best for paperback novels, telephone books, brochures, business reports, etc.—it is effective and considerably inexpensive.
