What is the difference between a lithograph and an original?

The difference between a lithograph and an original is that one is used to produce the other. An original is the term for the stone upon which an artist paints an image using an oil-based substance, such as a greasy crayon or tusche, a type of oily wash. The lithograph is the print that an artist makes with an original. To create a lithograph, oil-based ink is applied to the wet stone, adhering only to the oily image. The stone is then covered with a sheet of paper and run through a press. On 1stDibs, shop a diverse assortment of lithographs.
