A term describing the most common form of lithography (a printing process in which the image area and the non-image area co-exist on the same plane, rather than from raised or etched type, as in letterpress and gravure printing, respectively; see Lithography) in which a printed image is transferred first to a rubber blanket, and the blanket then transfers (or "offsets") the image to the paper or other surface. Other forms of lithography include ["direct lithography (or di-litho) and waterless lithography.
