In screen printing, a mesh screen is used to transfer ink (or dye or mustard!) onto a substrate, often paper or fabric in the case of books. A stencil is used to block areas where ink is not desired, and a squeegee is used to pull the ink across the screen. Stencils can be made from different materials such as freezer paper, contact paper, or photo emulsion. Painterly monoprints can be achieved through this process too!
