Planographic printing

Planographic printing means printing from a flat surface, as opposed to a raised surface (as with relief printing) or incised surface (as with intaglio printing). Lithography and offset lithography are planographic processes that utilize the property that water will not mix with oil. The image is applying a tusche (greasy substance) to a plate or stone. (The term lithography comes from litho, for stone, and -graph to draw.)
