Like GP2R, GP5W combines paper and an open-weave fabric. The fabric reinforces the book block and the paper caps the spine, combining a two-step process into one. Because this material is extremely strong, it is recommended for use on book blocks larger than 1.5" wide. It also reinforces the spine from head to tail and can be applied prior to rounding and backing, creating a very sturdy book block.
