Collagraph
A collagraph is an intaglio technique in which objects (cardboard, fibers, fabrics, organic materials etc) are added to the surface of the plate, usually heavy cardboard, until a low relief is achieved. Front, back and sides of the plate are then sealed with several coats of acrylic matte medium. Once the plate is dry it can be inked, wiped and printed in the same manner as a etched metal plate. Collagraphs can also be printed as relief images, without any ink as a blind embossing. Because the various levels on the plate are so easily achieved, it lends itself beautifully to multicolored and viscosity printing.
