Linocut, also called linoleum cut, type of print made from a sheet of linoleum into which a design has been cut in relief. This process of printmaking is similar to woodcut, but, since linoleum lacks a grain, linocuts can yield a greater variety of effects than woodcuts can.
Collagraphy is a really versatile printing process in which a textured plate is inked up and put through a press. Different textures hold varying amounts. of ink and print different tones.
