Lithography is best described as a planographic process; this is nothing more than a process for printing from a smooth surface, called a plate, to a substrate, generally paper. Marks from a hand-pulled lithograph will show a random dot pattern created by the tooth of the original surface. Offset lithography was an extended technology of lithography from stone.
