Lithography

Lithography is a method of printing, that was invented in 1796 by German Alois Senefelder. In the 19th century it was the only printing process, that could produce large print runs in colour. Since 1950 the Lithography was replaced by Offset printing.

The image is drawn on a stone plate (mainly Solnhofen limestone) with wax crayon. The stone is chemically treated, so that the fatty points are colored.
