What is stone lithography?
Stone lithography is a printing method that is based on the principle that oil and water do not mix. Using a greasy substance, an image is drawn or painted on to a flat stone. Next, the stone is moistened and the surface is then coated with an oil-based ink. Paper is pressed to the stone and the ink transfers the image onto the paper. The application of each color is printed separately through a careful alignment process called registration. The popularity of this process grew because thousands of replicas could be made which closely matched the color and graphic imagery of the original art.
