Lithography

Li*thog"ra*phy\, n. [Cf. F. lithographie.] 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.

lithography 
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).
