Pressing and cutting printed sheets

If the prints are processed further and bound to a booklet or magazine, a final trimming is almost always necessary. When spreads are stapled, performing an additional press fitting in a device or cutting machine can be useful. But similar to the folding or grooving steps, sheets can also stain one another during pressing and cutting. If a stack of printed paper is processed by a machine, it is important that the machine’s pressure is not set too high to prevent discolouration. For final trimming it is recommended to use paper areas which are at most slightly wetted with ink, since the heavily printed areas of a paper can soil the cutting machine.
