A unique print, typically painterly in effect, made by applying paint or printing ink to a flat sheet of metal, glass, or plastic. The painted image is transferred to paper either by manually rubbing or using a press. Mediums are applied to the plate using two different methods. In the additive, or “light-field,” technique, ink or paint is applied directly to the plate, often with a brush. In the subtractive, or “dark-field,” technique, the plate is covered with a layer of ink or paint, and the image is formed by manipulating and removing the ink or paint using a variety of tools, including brushes, rags, or the artist’s fingers. Each plate typically yields one monotype, but subsequent pulls (sometimes called “ghost impressions” because of their relative faintness) can be made from the residual mediums on the plate.
