P-numbers of books and books are generally multiples of 4, so we often need to do one (mainly post) to two (special post) when doing folding. I have seen a wide company make a picture book with more than 100 P. It uses a lot of A4 papers. It is wasteful and unnecessary to fold all the pages.
In normal folding, remember that no matter how you fold, the first page is in the lower right corner. Here are some common folding methods:

Note that the folding is different from the folding method in some cases, and the corresponding method of the specific situation needs to be further updated. The following four common ways of binding are attached for identification.
Binding. Generally divided into saddle stitching, flat bookbinding, rubber binding, glue binding. Our common magazines are used for saddle stitching; line-bound and wire-wrapping are flat-tie stitches; staple-bound glues are often used for large albums, but they are firm, but they are slow to be bound; they are often used for high-end small albums and overbooks. It is easy to degumming after repeated folding.
