Muriel Jackson (1901 − )
Muriel Jackson was born in London and studied at the Central School of Arts and Crafts. She was a painter and wood engraver (a member of the Society of wood-gravers). She was awarded the Logan Medal at the International Exhibition of lithography and wood engraving held at the Arts Institute of Chicago in 1939. She exhibited with the New English Art and the Red Rose Guild of art-workers.
An intaglio process whereby lines are cut into a metal or wood plate using an engraving tool (a burin), which is pushed in front of the hand to achieve a sharp controlled incision capable of great delicacy. This technique requires a great deal of control and is not suited to spontaneous mark-making.
Lithography means, literally, stone drawing. In addition to fine grain lithographic stones, metal plates can also be used for lithography. The method relies on the fact that grease repels water. An image is drawn in a greasy medium onto the stone or plate, which is then dampened with water. Greasy printing ink rolled onto that surface will adhere to the design but be repelled by the damp area. The inked image is transferred to the paper via a press. For large editions, the grease is chemically fixed to the stone, and gum arabic, which repels any further grease marks but does not repel water, is applied to the rest of the surface. For colour lithography the artist uses a separate stone or plate for each colour required.
