LITHOGRAPHY

lithography. Lithography, n. the act of ingraving upon stone

---

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.
