A work produced through photographic reproduction. Offset lithography can be a complex process. Using four or more color separations, the best facsimile of the artist's original is produced.
The inked image is set off from the stone or plate on to an intermediate rubber covered transfer cylinder before being printed. In photo offset lithography the image is photographic in nature and then transfered onto specially sensitized plates and processed before printing.
The most widely used method of printing during which a photomechanical reproduction is created by the separation of colours in the original and then the recombining of those colours on a printing press.
