Definitions for "offset printing"
A printing technique in which a lithographic image on an inked metal or stone plate is transferred first to a rubber sheet (usually on a cylinder) before transfer to the paper. Called also offset lithography.
The most common commercial printing technology in use today. Offset printing applies layers of ink on the page. For each layer, a reverse image of the page is placed on a roller in the printing press. Ink is applied to the non-image areas on the roller, so that as the roller presses against paper moving through the press, the proper image is left on the paper.
Printing that uses an intermediary transfer such as a rubber blanket before the paper is printed. There is no reversal of the image in this process.
