Monotypes

Monotyping is a type of printmaking made by drawing or painting on a smooth, non-absorbent surface. Roy uses was a zinc etching plate, as matrix. The image is then transferred onto a sheet of paper by pressing the two together, using a printing-press. Monotypes can also be created by inking an entire surface and then, using brushes or rags, removing ink to create a subtractive image, e.g. creating lights from a field of opaque colour. The inks used may be oil based or water based. With oil based inks, the paper may be dry, in which case the image has more contrast, or the paper may be damp, in which case the image has a 10 percent greater range of tones.
