Electrophotographic color proof generating apparatus includes a charger station, an exposure station, and a development station. Starting with color half-tone separations of artwork, the apparatus, using a unique method, electronically controls the exposure and potentials at the charger and development stations to generate a proof. The apparatus is designed to generate proofs which match the dot gain or loss and density of press sheets printed by a great variety of commercial presses starting with the same separations as are used to form the proofs. The separations are then modified until the apparatus generates a proof which is an acceptable reproduction of the artwork. The modified separations are then used to generate a press sheet on the commercial press which will be an acceptable reproduction of the artwork.

An electrophotographic imaging method is described that uses an element comprising a photoconductive layer on an electrically conducting substrate capable of transmitting actinic radiation to which the photoconductive layer is responsive, and a dielectric support, releasably adhered to the substrate, comprising the photoconductive layer or an overcoat thereof forming a surface of the element capable of holding an applied electrostatic charge. To use the element, the surface of the dielectric support is charged, and the photoconductive layer is imagewise-exposed to actinic radiation, thereby forming a developable electrostatic image on the dielectric surface. The electrostatic image, in turn, is developed with toner to form a first color image. A composite color image is formed on the element by repeating the sequence one or more times with imagewise exposure of the photoconductive layer to actinic radiation transmitted through the substrate, and developing over each preceding image with a different color toner. The composite toner image is transferred with the dielectric support to a receiving element to form a color copy such as a three-color filter array or a color proof closely simulating the color print expected from a full press run.
10 Color proofing method and article US838486 1986-03-11 US4657831A 1987-04-14 Joseph H. Ambro; Lawrence E. Contois
Electrophotographic color proofs of half-tone dot pattern images are made which closely simulate the dot gain of prints made with lithographic plates and liquid inks. In forming the color proof, a thin transparent plastic sheet having on one side an electrophotographic toner dot pattern image is laminated to a reflective support with the toner image side in contact with the support. A thicker transparent plastic sheet is laminated to the other side of the thin sheet. The resulting color proof comprising a toner dot pattern on a reflective support and covered by a thin transparent layer and a thicker transparent layer has an apparent increase in dot size which simulates that of a press print.
