All of these prints are unique and created individually by Schaller. Each color is individually applied by pulling the ink through a stenciled screen.
The print editions are small because of the this timely process. Silkscreen was derived from a stencil process and has been used by sign painters since 1938 for labeling, posters, bottles and fabrics. A nylon mesh (screen) is stretched over a wooden frame, coated with a photographic emulsion and an image is burned into the light-sensitive emulsion. The framed screen is place on the surface to be printed, an ink is pressed through the framed screen with a rubber squeegee. This process requires separate screens for each color. The image can then be duplicated using the various screens.
