Offset printing is the most common technique used where the inked image is transferred (or "offset") from a plate to a rubber blanket, then to the printing surface. It uses the non-mixing quality of oil and water in its lithographic process and employs planar image carrier on which the image to be printed obtains ink from ink rollers, while the non-printing area attracts a film of water, keeping the non-printing areas ink-free. Offset printing can be done on paper and board.
