Serigraphy, the printing term for the silk-screen process, is a fine art process in which editions are created by meticulously screening the colors of an image onto the back of an acetate cel or the surface of fine art paper or canvas – one color at a time. The image is separated into its individual colors, then each is transferred onto a stretched screen of silk which acts like a stencil. Inks are forced through the stretched screen onto a cel, fine art paper or canvas, one color at a time. When all of the individual colors are screened onto the cel or paper, together they form the complete image. Silk-screened cels – called sericels – are typically modest in price since their edition sizes are open or large, and are not hand-signed. Limited edition serigraphs on paper or canvas are typically hand-signed by the artist indicating their personal approval of each work of art, then individually numbered to identify each work of art as a part of the total edition.
