In drypoint, the artist "draws" directly on a copper plate with a sharp stylus. No etching is involved. The point of the stylus creates a "burr" of copper on either side as it is scored through the metal. In the printing process, the burr (if not removed) holds additional ink, providing a velvety richness unique to this method. Artist Gunnar Norrman (1912-2005) worked in drypoint for over 50 years. Because the copper burr wears down from the weight of the press, Norrman kept his print editions small (sometimes as few as four prints in an edition) in order to retain the delicate clarity so characteristic both of Norrman's work and of the drypoint technique itself. Other examples of drypoint can be seen in the works of Hermine David, Jules Pascin, and Paul César Helleu.
