Monoprinting on gelatin plates gives a unique result popular with many printmakers. While gelatin plates ultimately deteriorate, Gelli Arts Gel Printing Plates are actual reusable printing surfaces. They look, feel, and react like a gelatin plate, but are made of a unique plastic that contains mineral oil. They do not contain any latex or animal products. Acrylic paint, water-soluble inks and fabric paints work best to create interesting one-of-a-kind monoprints - No printing press needed! Easy cleanup with soap and water.
