A lithograph is a type of printing process during which original works of art can be printed and reproduced; the final product is also known as a lithograph, which is an authorized copy of an original work created by an artist or other skilled craftsmen. The printing process for creating lithographs is different from other traditional methods, mainly because it does not require the print-maker to first etch the image into metal plates. Prints can be made of original works of art, first created on the stone table or metal plate, or images from paintings or drawings can be duplicated with this method. If the print quality of a lithograph is excellent and the production numbers are low, it may have significant value in the art world.
