Definitions Serigraph A process where-by designs are stenciled onto a fine mesh fabric that has been stretched on a frame. Liquid ink is poured onto the screen and scraped by a squeegee through the open areas of the screen onto the paper placed beneath the frame. This process is also known as silk-screen printing because originally silk was used for the fabric. This multicolor printmaking technique was developed in America in the late 1930’s.   Soft-ground An Intaglio process that involves the use of a waxy solution applied to the plate for the purpose of drawing a grainy line, imprinting textile patterns or elements from nature such as leaves. The soft-ground usually does not require a varnish to stop out areas that are to be protected from the bite of the acid as the ground itself prevents the acid from etching excepting in the areas where the ground has been imprinted or displaced.   Substrate The surface layer in a two dimensional art work. Paper is most often the substrate for prints and drawings. Canvas is usually the substrate in a painting.   Suite A set of prints related by a common theme or imagery.   Trial Proof An experimental print created during the development of an editioned print. A trial proof may vary in size or color from the editioned print.
