Electrophotographic color proofing apparatus and method |
摘要 |
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.
