Collagraphs demonstrating both relief and intaglio-inking.
Collagraphy (sometimes spelled collography) is a printmaking process in which materials are glued or sealed to a rigid substrate (such as paperboard or wood) to create a plate.[1] Once inked, the plate becomes a tool for imprinting the design onto paper or another medium. The resulting print is termed a collagraph. The term "collagraph" was coined by Glen Alps in the 1950s, and is derived from the Greek word koll or kolla, meaning glue, and graph, meaning the activity of drawing.[2]
Examples of collagraph plates using a variety of materials.
Artists use a variety of materials in collagraphy, including yarn, fabric, tape, different varieties of cut paper or card, leaves, and acrylic mediums.[3][2] The application of ink onto the collagraph plate is versatile, consisting of intaglio-inking into recesses, brayer or paintbrush inking onto relief surfaces, or a combination of these methods. A print can be made with or without use of a press.[4]
