- Carborundum
- is a mineral, often found in powdered form, used as an abrasive. When mixed into a paste with glues it can be easily painted on a flat plate. When dry & hard, the paste will hold inks and can be printed many times in a standard etching press. Inking, wiping & printing of the plate is done the same as standard etching techniques.
- Collagraph
- is a print made from collaged materials, pasted onto the surface of a flat matrix or plate. Plates can be metal, cardboard, plexiglas, etc. Materials can be almost anything that are not so high that they harm the etching press. These include fabrics, papers, flowers, seeds, pasta, coins, feathers, etc. The differentiation between a collagraph and other etching & drypoint (often called intaglio) processes is that the image of a collagraph is formed on top of the plate's surface. Etching & drypoint techniques cut into the plate to create an image below the surface.
- Edition
- is a set of prints of the same image and with all other elements (color, paper, etc.)being the same. In this context the set of prints is of a limited number (also called 'limited edition'), hand printed and each print is signed and numbered by the artist. An example of a number on such a print: 5/20 indicating that it is the fifth print in an edition totalling twenty.
- Etching
- is the method of cutting into metal, often by use of caustic materials (acids), to create an image. The areas not to be etched are protected by acid-resistant grounds. It is also the name of the type of print made by this process and is often used interchangeably with 'intaglio'.
- Mezzotint
- is a centuries-old printing process. A metal plate is pierced by a 'rocker', creating minute holes or dots in the surface. One must rock in many directions until an even ground is achieved. The dots and their resultant burr (particle of metal displaced by the piercing) are what hold the ink, producing a velvety black. The artist then uses a 'burnisher' or 'scraper' to smooth the incised ground creating grays and white due to the holes holding less ink. For more information read "The Mezzotint" by Carol Wax (Abrams).
- Pochoir
- is the French term used for stencil printing.
