LITHOGRAPHY
Li *thog "ra *phy, n. Etym: [Cf. F. lithographie. ]
Defn: The art or process of putting designs or writing, with a greasy material, on stone, and of producing printed impressions therefrom. The process depends, in the main, upon the antipathy between grease and water, which prevents a printing ink containing oil from adhering to wetted parts of the stone not covered by the design. See Lithographic limestone, under Lithographic.

The earliest forms of lithography used greasy ink to form an image on a piece of limestone that was then etched with acid and treated with gum arabic. In a modern press, rollers transfer ink to a thin aluminum plate wrapped around a cylinder. In offset lithography the image is transferred to an intermediate rubber-covered cylinder before being printed.
