limited edition lithographs
Lithography (from Ancient Greek lithos meaning 'stone', and graphein meaning 'to write') is a method of printing originally based on the immiscibility of oil and water. The printing is from a stone (lithographic limestone) or a metal plate with a ball grained surface. It was invented in 1796 by German author and actor Alois Senefelder as a cheap method of publishing theatrical works. Lithography can be used to print text or artwork onto paper or other suitable material.
In modern lithography, the image is made of a polymer coating applied to a flexible plastic or metal plate. The image can be printed directly from the plate (the orientation of the image is reversed), or it can be offset, by transferring the image onto a flexible sheet (rubber) for printing and publication.
In printmaking, limited edition is a fixed number of impressions produced on the understanding that no further impressions (copies) will be produced later. Most imited editions is normally signed by the artist in pencil, and numbered as say 67/100 to show the unique number of that impression and the total edition size.
