Aquatint A process where the plate is etched through a porous ground of powdered and melted resin, so as to produce a texture when printed. The surface of the plate is worked by rocking a serrated tool, which forces the metal to sit on the surface of the plate. When inked the surface prints a rich black. In carborundum printmaking, the areas in the plate which are to print black are covered with a mixture of carborundum, an industrially produced substance, and a binding agent. When dry that area retains ink just as in any other intaglio process.
Carborundum printing gives a rich velvety surface.
The plate is covered with glue, and drawn into with any implement. When dry, it is inked, wiped and printed.
