摘要： A calibration procedure for an electrophotographic proofing system of the type for generating color proofs during multiple image cycle proofing runs from imaging information representative of half-tone color patterns for each of a set of colors by sequentially, during the imaging cycle for each color of the set, charging a photoconductor as a function of a charge model representative of photoconductor contrast voltages as a function of a charging grid voltage, modulating a laser as a function of the color pattern information to expose the photoconductor, and toning the exposed photoconductor as a function of a development model representative of measured developed toner color densities as a function of development voltage. The calibration procedure generates charge and development models for each color of the set during one proofing run, and includes: i) charging a plurality of first color test patches on the photoconductor, each with a different known grid voltage from a range of grid voltages; ii) exposing the first color test patches on the photoconductor; iii) measuring the contrast voltages of the photoconductor at the first color test patches; iv) toning the first color test patches as a function of known development voltages; v) measuring the of the toner at the first color test patches; vi) repeating steps i-v for each remaining color of the set during one proofing run; vii) generating a charge model, for each color of the set, representative of the measured contrast voltages as a function of the associated grid voltages; and viii) generating a development model, for each color of set, representative of the measured toner densities as a function of the associated development voltages.

摘要： A method for operating an electrophotographic proofing system for generating color proofs from image information during multiple imaging cycle proofing runs. Charge model information, development model information and toner replenishment model information are stored for each component color. Actual photoconductor charge characteristics are measured during the imaging cycles of the proofing runs. Actual toner characteristics from component color test patches developed during the imaging cycles are also measured. The photoconductor is charged during the imaging cycles as a function of the charge characteristics measured during a preceding imaging cycle for the same component color, and a as function of the charge model information for the color. The photoconductor is toned during imaging cycles as a function of toner characteristics measured from test patches during a preceding imaging cycle for the same component color and as a function of the development model information for the color. Working toner is replenished after the imaging cycles as a function of the development parameters used to tone the photoconductor during the imaging cycles for the same component color and as a function of the replenishment model information for the color. Charge model information and the development model information for each component color are updated as a function of measured values after the imaging cycles.

摘要： A liquid color toners handling network for an electrographic printer includes a plurality of developing modules. Each developing module in turn includes a toner handling system having a toner supply reservoir with a toner pump coupled to a reservoir outlet. A T-connector is coupled to the toner pump and is further coupled to a toner supply reservoir inlet. A three-way ball valve is coupled in series with the T-connector and an inlet of the developing module. An additional fluid line couples an outlet of the developing module back to the three-way ball valve. This arrangement allows toner to be trapped between the three-way ball valve and developing module inlet so that toner can be supplied to the developing module in an instant-on manner. The handling network further includes a toner carrier pumping module that can be coupled to any one of the supply reservoirs and a toner concentrate supply container associated with each supply reservoir. This arrangement allows toner carrier and toner concentrate to be mixed within a static mixer associated with the supply reservoirs. A toner/air vacuum separator coupled betwen the developing module outlet and the three-way ball valve is further coupled to a vacuum pumping module. The vacuum pumping module includes a maintenance vacuum separator and a suction cleaning line that can be used to perform routine cleaning maintenance on the developing modules.

摘要： A structured surface is formed with the method of the present invention. The method of making this structured surface includes the steps of applying an ablatable radiation sensitive coating on the major surface of the substrate, and exposing the ablatable radiation sensitive coating to radiation such that exposed portions of the ablatable radiation sensitive coating ablate from the substrate to form a structured surface. The structured surface then includes a substrate and a pattern of structures framed by at least one separation bank. The method may also include the steps of depositing a flowable material on to the structures and the separation bank to form a pattern of flowable material in the structures.

摘要： A mask-forming film has a transparent layer between the imageable layer and the carrier sheet, which transparent layer has a refractive index that is lower (by at least 0.04) than that of the carrier sheet or any immediately adjacent layer between it and the carrier sheet. This lower refractive index layer modifies the path of incident radiation during mask image transfer so as to provide steeper shoulder angles in the relief image solid areas.

摘要： A developing module for depositing liquid toner on an imaging surface of a photoconductive member includes a development electrode. The development electrode is supported by a shroud which includes a toner supply passageway. The supply passageway is coupled to a pump mechanism that delivers liquid toner to the development electrode from a supply sump. Liquid toner flowing across the development electrode is deposited on the imaging surface of the photoconductive member. The shroud further includes a toner return passageway coupled to a vacuum source. The vacuum source removes from the development electrode liquid toner that has not been deposited on the imaging surface of the photoconductive member. In addition, the vacuum source removes air from around the development electrode. A vacuum chamber is mounted to the shroud adjacent the toner return passageway and is further coupled to the vacuum source. The vacuum chamber separates the air drawn off of the development electrode from the undeposited liquid toner.

摘要： An electrical charging system for repeatedly electrically charging a photoconductor layer on an electrical conductor through charging that photoconductor layer, selectively discharging it, providing toner on the layer, and removing the charge image in the photoconductor for each of as many toners as desired for forming a final printed image, followed by using a removal radiation of a shorter wavelength on the photoconductor to avoid long term changes in the photoconductor. A further charging cycle may be used before the next printed image operation begins.
