I call this technique Silk Collagraph. (I have seen others call it “silk mezzotint”.) The plate is made of mat board – a leftover piece cut out when framing another piece. Silk screen fabric was glued to the surface and sealed with acrylic gesso. in a series of layers painted with the gesso, the mesh of the fabric was filled until it produced a variety of tones, depending on the amount of mesh still available to hold ink. Think of it this way – areas with no layers of acrylic print a rich black. Areas with a lot of acrylic wipe clean and print white. Plate is inked and printed in the same manner as an etching.
