Paint the area to be lifted from the printing plate with melted soy wax on the printing plate. Let the wax air dry completely on the plate and paint over the plate with Lascaux Hard Resist the same way as you would apply it as a hard ground. Let the plate dry at room temperature 10 minutes or until it is touch-dry. Dry it with a hair dryer and the hard resist hardens like any other acrylic etching grounds where it is located directly on the printing plate, while the lift media melts and can be removed with a cloth. The plate is degreased and can now be etched right away creating open bites or sprayed with aquatint before etching.
This Lift-Ground has been developed by my good friend MarnixEveraert, teacher of non-toxic intaglio at Academie vor bildende Kunst in Gent, Belgium
