Lithography - plane surface printing method based upon the antipathy of oil and water. In offset lithography, the image is first picked up by a rubber blanket, which in its turn transfers the design to the paper. In modern photo-lithography the image is printed photographically on to an etched or grained zinc or aluminium foil or plate, which can then be attached to the cylinder of a rotary press.
