Artist Proof Those impressions from an edition that are specifically intended for the artist's own use. These impressions are in addition to the numbered edition and are so noted in pencil as artist proof or A/P.

Etching To make an etching, a metal plate is coated with an acid-resistant wax-base substance called a ground. An etching needle, which has an extremely fine point, is used to draw the image on the plate. The surface ground is removed wherever the point of the needle makes contact with the plate. The plate is immersed in a tray containing an acid bath. The acid bites into the plate in the lines exposed by the etching tool; the length of time the plate is exposed to the acid determines the strength of the line.

Giclée The most technologically advanced and accurate method of creating images on fine art paper or canvas. Ink jets smaller than a human hair spray acyrlic inks onto the print medium, which is attached to a rapidly spinning printer drum. A protective UV coating "fixes" the image.

Limited Edition Print Indicates that a finite number of prints may be made of an image. Each print is signed and numbered by the artist. Numbering indicates the size of the edition and the number of each particular print. Therefore, 25/75 means that the print is the 25th impression from an edition of 75. Once the edition is sold out, no additional images may be printed.

Lithograph A printing process in which images are drawn with crayon or a greasy ink on stone or metal and then transferred to paper. Each image is produced individually.

Open Edition Print Prints of an image not limited to a specific number. If an open edition sells out, more prints may be made. Generally considered less valuable than limited edition prints.

Serigraph A fine art stenciling method in which the image is transferred to the paper by forcing ink through a fine mesh in which the background has been blocked. Each image is produced by hand and the process must be repeated for each color used in the image.
