An intaglio technique that does not involve using acid. The surface of the plate is pitted with minute indentations – using a rocker – which hold the ink. Tones are achieved through burnishing the plate.
An intaglio technique in which the surface of the plate is covered with an acid resistant material called ground. The image is drawn into this to expose the metal underneath. The plate is then immersed in an acid bath. Only the exposed parts of the plate are bitten (etched) away by the acid. The depth of the etch is controlled by how long the plate is in the acid and how strong the acid is. The most deeply bitten lines will hold the most ink and be the darkest areas of the print.
A design is impressed into the paper with intaglio or relief printmaking processes but without using any ink. This creates an area of raised relief.
An intaglio technique which does not involve the use of acid. A sharp, round point is used to scratch the image and where the metal is thrown up on either side of the scored line it produces a burr, creating a characteristic soft, rich line. The plate can wear quickly during the printing process.
An intaglio etching process used to create a range of tone. A fine rosin is dusted over the plate and it is then heat fused. Acid is used to etch through the finely grained resist of the rosin dust.
