Perfect binding
In Perfect binding the signatures are folded individually and stacked along the common fold, which forms the spine
of the booklet.
A signature is a press sheet that is folded to form the pages of a booklet in sequential order. Each signature in a
booklet is folded in the same way. The Perfect binding process is more involved (the spine must be roughened to
flatten before it is glued to the cover) and tends to require a larger gutter. In Perfect booklets, creep is not a factor.
