Prints, Planographic

Planographic printing, one of the four main printing processes, is by pressing smooth paper across a smooth surface, or plane; hence the word "planographic." The surface carries the image, inked with an ink roller that leaves ink only on what the artist has intended to print. The most common planographic printing process is lithography in various forms such as stone litho, plate litho and vitreography. The image above is a lithograph printed from a stone drawn and printed by Ritchie, his "Target Heart I" from 1973.
