Using a variety of techniques, students will learn to compose and produce multicolored, multilayered monotype prints. We will begin by inking plexiglass plates to produce color flats, patterns, shapes and textures to which we will add other imagery, abstract layers, stenciled shapes or impressions of found materials depending on each student’s artistic goals.
Over the course of the class it will be possible to produce a number of finished artworks or just to learn how to use and combine various processes including drypoint etching and linoleum or Speedy-Cut block relief prints. Consider bringing some materials for inspiration such as photographs, sketches, or ideas that you would like to work from or explore.
