A printing technology that dates back to 1798 when Alois Senenfelder developed a method of imaging limestone from which a print was produced. Based on the principle that oil and water do not mix, an aluminum or plastic plate is coated with a photopolymer film that is exposed to light through a photographic mask. The exposed areas are chemically "hardened," and the unexposed areas are dissolved when the plate is put through a chemical process, which is the next stage. When printing a page, the plate is dampened, and the water adheres only to the unexposed, non-image areas, which repell the greasy ink that is applied to the plate immediately thereafter.The most common lithographic printing uses the offset method, in which the ink is "offset" onto a rubber-coated cylinder that is pressed against the paper.
