Alternatively, printer’s proofs are reserved for the printer and are inscribed “P.P.”īon à Tirer (B.A.T.): A print that is not included in the edition, but which indicates the standard a printer tried to duplicate for the edition. An artist’s proof can be identified by the inscription “A.P.” found in the lower left-hand margin. Chine is French for “China,” which refers to the thin Asian paper originally used with this technique, and collé means “glued.”Ĭollagraph: A technique of relief printing using any combination of actual elements such as cardboard, fabric, washes, carborundum (an abrasive powder), or found objects, which are adhered to a plate, inked, and printed.Īrtist’s Proof (A.P.): A print reserved for the artist and not included in the numbered edition. Usually the more an area is eaten away, the more ink will transfer during printing, and the darker the tonal area will be.Ĭhine-collé: The process of adhering one piece of paper to another by using a liquid adhesive and running them together through the printing press. Finally, damp paper is laid on the plate, and they are run through a press, transferring ink in the shape of these areas. Once the rosin is removed, the plate is inked, and ink collects in those areas with uneven surfaces. When the plate is submerged in a corrosive bath, tiny areas unprotected by the rosin particles are “eaten away”, creating recesses. Powdered rosin is distributed across a metal plate and adhered through heating. The artist scratches off the resist using a variety of etching tools: these lines are etched into the plate by exposing the bare metal to acid.Īquatint: An etching technique that creates printed tonal areas. Resist: An etching resist (such as hard ground or asphaltum) is applied to the plate in order to prevent an acid solution from corroding the surface. Relief Carving Tools: Tools, such as chisels and knives, used to carve into a matrix of wood or linoleum.
Matrices used in printmaking include blocks of wood, sheets of linoleum, metal plates, sheets of Plexiglass, and slabs of limestone. Most, though not all, matrices are able to print the same image many times. Matrix: A physical surface that can be manipulated to hold ink, which is then transferred to paper. The concentration of this bath is precisely measured, as is the period of a plate’s submersion.īaren: Hand tool used to firmly rub the back of the sheet of paper in order to pick up ink from the matrix.īrayer: A roller used to spread ink on a matrix. Acid: A term sometimes used to refer to the corrosive solution in which a metal plate is etched for intaglio printing.
