Latest Patents

Hirsch holds a patent for an electrophotographic method of generating electrostatic images on two sides of a transparent, highly insulating foil. This method involves generating electrostatic charge images of identical shape but opposite sign on both sides of the foil. Subsequently, pigment is deposited on both sides using oppositely charged developers. This technique enhances the optical density of an electrophotographic image on a transparent insulating foil, achieving greater density for a given surface charge density by establishing a charge exchange between one side of the foil and an electrode. The electrode and the foil are separated prior to development, allowing for improved image quality.
