Description
When the lithograph printing process was developed in 1796, Aloys Senefelder used a flat stone for the drawing and printing surface. A lithograph stone is usually a fine-grain limestone. Limestone is able to take a high polish but still retain enough porosity to accept the drawing lines. An oily liquid (tusche) or a greasy crayon (lithograph crayon) was used to draw the pattern on the stone. The drawn stone is treated with an etching solution of acid in gum arabic. The etch creates distinct greasy and non-greasy regions. Once the etchant is removed, the stone is sponged with water then rolled with an oil-based printing ink. The ink is attracted to the drawn, or greasy, areas while the water is retained in the etched areas. Lithograph paper is placed over the ink image, then rubbed, scraped, or pressed to transfer the image to the paper. Currently, lithographs are made on metallic sheets of zinc (zincograph) or aluminum.
