The card print process is a technique pioneered by Sheila Robinson as recently as the 1960's. A form of collagraph using thick mountboard, it involves cutting into the board as with a linocut, but you can also tear the top layer of the card away to create fuzzy textures alongside more solid areas of colour, created by the uncut areas of card. The card itself only survives a few prints before it starts to fall apart, so editions are small. This can be extend by applying glue or shellac to them and being used in other works.
