Serigraph: (Screenprint, Silkscreen) A stenciling method in which the artist's image is transferred to paper by forcing ink through a fine mesh screen in which the background has been blocked. A separate stensil is required for each color within the print. This method, like the woodcut, involves the artist working on the areas that are not actually printed.

Lithograph: A printing process in which the image to be printed is drawn by the artist on a slab of limestone or a metal plate. This original artwork is then treated to receive ink while any blank areas within and around the image repel the ink. Paper is then laid onto the image under pressure and a print is created.

Etching: (Engraving, Aquatint, Drypoint, Mezzotint) A printing process in which an image is incised or etched into a metal plate using a variety of techniques and tools. Ink is then applied to the recessed areas. The paper, which is dampened, is squeezed thorough a press under enormous pressure and receives ink from the incised marks. Unlike lithography, the finished impression is often raised slightly from the paper surface.

Artist Proof (AP): A print outside of the regular, numbered edition but equal in quality to it. Often, an artist will retain artist proofs for private sale. The number of artist proofs are small in proportion to the regular numbered edition, usually less than ten percent of the regular numbered edition.

Printer Proof (PP): A print, usually in a numbered edition of 10 prints or less, created by the artist during printing for the express purpose of providing prints to the collaborating printmaker as a gift or as partial compensation for his or her services.

Trial Proof (TP): A print, usually a single, unique impression, created by the artist during printing to document image changes or as an experiment with color variations.
