Other forms: lithographs; lithographed; lithographing
A lithograph is a print that's made using a stone or metal plate. Lithographs are etched into the plate using a chemical reaction.
To make a lithograph, an artist draws a design or on the stone plate with a waxy crayon or oil-based ink. After treating the plate with several layers of material, including rosin, talc, and an acidic solution, the lithographer applies ink with a roller. The oily ink only sticks to the waxy image, not the area around it; the resulting lithograph is a crisp reverse image on paper. The Greek roots of lithograph mean "stone" and "to draw."
