How does a lithograph differ from other fine art prints?
Lithographs differ from etchings, engravings, serigraphs and woodcuts in materials and process. For example, etchings and engravings are printed from a metal plate with incised lines while a lithograph is made from a chemically treated, flat surface. A serigraph is a silkscreen print, and woodcuts are printed from blocks of wood carved in relief. In each case, what distinguishes the print as original is that the artist participates directly in the creation of the image and approves all impressions by signing and numbering each print.
