ABSTRACT:
A device for applying pressure to a pressure sensitive duplicating master and a sheet of copy paper positioned on a hard surface includes two rollers of differing hardness. The rollers are used simultaneously with the harder roller applying substantial duplicating pressure while the softer roller conforms to irregularities in the hard surface and prevents these irregularities from causing voids in the duplicated image.
