Paper Plate
A printing plate made of strong and durable paper in the short run offset arena (cost effective with short runs).
Parallel Fold
Method of folding. Two parallel folds to a sheet will produce 6 panels.
Paste-up
To paste copy to mounting boards and, if necessary, to overlays so it is assembled into a camera-ready mechanical. The mechanical produced is often called a paste-up.
Perfect Bind

Perf Marks
On a "dummy" marking where the perforation is to occur.
Perforating
Taking place on a press or a binder machine, creating a line of small dotted wholes for the purpose of tearing-off a part of a printed matter (usually straight lines, vertical or horizontal).
Pica
A unit of measure in the printing industry. A pica is approximately 0.166 in. There are 12 points to a pica.
Picking
Phenomenon of ink pulling bits of coating or fiber away from the surface of paper as it travels through the press, thus leaving unprinted spots in the image area.
Pixel
Short for picture element, a dot made by a computer, scanner or other digital device. Also called pel.
Plate
Piece of paper, metal, plastic or rubber carrying an image to be reproduced using a printing press.
Platemaker
