Perfect Bound Book Block - 1 of 2

This is a way to make a strong binding of sheets of paper. The spine gets sawn-in cords and is lacerated to give more surface for the glue to grab onto. It is important for the bound edge to be running parallel with the grain of the paper. If your planned book has the grain running the wrong way through the printer, you could buy larger paper and cut it with the grain running correctly before printing. If the book is large and the paper is light weight the grain may not be as important. It is more important when the book is smaller. Books always open easier and are more usable when the grain is running parallel to the spine.
