Printmaking: Collagraphs/Collage Blocks A Collagraph print is a collage printmaking technique and is a form of Intaglio printing. The collagraph plate is printed in the same way as etchings, but also include the basic principle of relief printing and can be printed either as intaglio or relief. The term collagraph refer to a collage board where the materials are assembled on a flat base or plate (matrix) to form a relief block with different surface levels and textures. Collagraph plates are created by sticking and gluing materials like textured paper or fabric onto the plate and then coat it with varnish or acrylic medium afterwards to protect the materials. The plate can be made from wood plates or cardboard plates that you build up using different materials.
