Soft Cover Catalogs
The milled paperback, also known as a cutter or glue, is one of the most used bindings for the creation of catalogs, magazines, magazines and books.
It is called this because the block of signatures (ie the sheets of the publication folded into quarters, eighths, sixteenths, thirty-second ones, etc.) is cut on the back with a cutter to facilitate the penetration of the glue.
