the art or process of producing a picture, writing, or the like, on a flat, specially prepared stone, with some greasy or oily substance, and of taking ink impressions from this as in ordinary printing.
a similar process in which a substance other than stone, as aluminum or zinc, is used.
1813, from Ger. Lithographie (c.1804), coined from Gk. lithos "stone" + graphein "write." The original printing surfaces were of stone. Process invented 1796 by Alois Senefelder of Munich (1771-1833). Hence, lithograph "a lithographic print," a back-formation first attested 1828. Earlier senses, now obsolete, were "description of stones or rocks" (1708) and "art of engraving on precious stones" (1730).
