Assembly pressure
The assembly or material printing is one of the high pressure processes . Wire, pieces of sheet metal, metal nets, stones, cords, nails are mounted on the printing plate, riveted or soldered and then printed on mostly particularly soft paper.
In the case of direct printing , the materials (colored or uncolored) form the printing block. With indirect printing , a roller is passed over the object (either the roller is strongly colored and the object is not colored or vice versa) and then printed on paper. Occasionally, as with Jean Dubuffet, the result is printed on stone and then peeled off on the stone after further work.
