Lithography

Lithography is a type of art that I am just now learning about. According to Digital Visual Culture, Aloys Senefelder discovered lithography "through a wonderful mixture of chemistry and physics with art, craft, skill, and luck, Senefelder made it possible to print multiples of an illustration drawn upon a perfectly flat stone surface" (p.25). Lithography is described as a way to produce multiple prints with a special press as well as with grease and water. According to Brittanica, the "ink is applied to a grease-treated image on the flat printing surface; nonimage (blank) areas, which hold moisture, repel the lithographic ink" which is then used to print more images. http://www.britannica.com/EBchecked/topic/343748/lithography#toc4234

This picture shows how lithography is done. The screen easily prints the image through the process of lithography.
