Lithographic printing is a traditional method of printing using plates, inks and water. It differs from digital Giclée printing in that large metal plates and pressured rollers are used to physically transfer the image, with the inks and water being absorbed into the paper itself.
Lithography was first invented by Alois Senefelder in 1796 and over the last 300 years artists including Picasso, Chagall, Henry Moore, David Hockney and Andy Warhol have reproduced copies of their original paintings using these Lithographic printing techniques.
