Works created by using a resist material, such as tempera, gouache, waxy crayon, or another material, to create a design on a support, usually heavy watercolor paper. The design is covered with ink, allowed to dry, and the ink is washed off. In areas where the underlying material was omitted or thinly applied, the black ink pervades; in areas where the underlying material was more thickly applied, its color and texture remain. (en)
