Abstract: The present invention relates to the manipulation of differential gloss as may be inherent in halftoned images. By selectively applying halftones with anisotropic structure characteristics which are significantly different in orientation while remaining identical in density, a gloss image may be superimposed within an image without the need for special toners or paper. Conventional copier systems will not typically be able to copy such a superimposed gloss image.

Abstract: The present invention relates to protecting printed items intended for public exchange having important informational indicia provided therein. The print items are protected from tampering by providing an informational indicia image as a glossmark. By selectively applying halftones with anisotropic structure characteristics which are significantly different in orientation while remaining identical in density to render information indicia, a glossmark image is produced of the information indicia. Such an information indicia glossmark image when provided in print item image helps protect that print item image from tampering.

Abstract: An imaging system for effecting electrostatic printing of an image, wherein the imaging system includes an electrostatic printing engine operable in a novel fashion upon a copy substrate, for imaging and development of an electrostatic latent image representative of the image, and subsequently transfers the developed image to the copy substrate. A quantity of low solids content liquid developing material is subject to compression in a process nip such that the concentration of marking particles therein increases and the concentration of carrier fluid decreases. A toner cake layer is thereby formed in the process nip, and is used for development of the electrostatic latent image in a development zone situated in the process nip.
