Collagraphy is an engraving process introduced in 1955 by Glen Alps in which materials are applied to a rigid substrate (such as cardboard or wood).

The word is derived from the Greek word koll or kolla, meaning glue, and graphic, meaning the activity of drawing. The plate can be inked with a roller or a brush or a combination of these. Ink or pigment is applied to the resulting collage, and the board is used to print onto paper or other material using a printing press or various hand tools. The resulting print is called a collagraph.

Substances such as carborundum, acrylic texture mediums, sand papers, textiles, bubble wrap, twine or other fibers, die-cut card, leaves and grass can all be used to create the collagraphy plate. In some cases, the sheets can be usedModelage as a source of pigment by rubbing them against the surface of the plate. Subscribe to Collagraphie
