Plate - Piece of paper, metal, plastic or rubber carrying an image to be reproduced using a printing press.

Platemaker - (1) In quick printing, a process camera that makes plates automatically from mechanicals. (2) In commercial lithography, a machine with a vacuum frame used to expose plates through film.

Plate-ready Film - Stripped negatives or positives fully prepared for platemaking.

Pleasing Color - Color that the customer considers satisfactory even though it may not precisely match original samples, scenes or objects.

PMS - Obsolete reference to Pantone Matching System. The correct trade name of the colors in the Pantone Matching System is Pantone colors, not PMS Colors.
