摘要： A technique for profiling a color printing device employs a modified Neugebauer color mixing model. The modeling technique makes use of a variable dot gain value and 'n factor.' The variable dot gain adjustment value may vary according to the particular tristimulus channel under evaluation. In addition, the variable dot gain value may vary according to the particular Neugebauer primary over which a halftone dot is printed. Accordingly, the technique may rely on an array of different dot gain values and n factors that correspond to different combinations of color channels and overprint conditions. As a further feature, the techniques may rely on a dot gain formula that relates halftone dot variation, i.e., fringe thickness, to the size of the halftone dot. This relationship tends to produce a dot gain model that more closely resembles the actual dot gain behavior on a printing press.

摘要： Infrared absorbing compounds are disclosed. The compounds are co-polymers that comprise covalently attached ammonium, sulfonium, phosphonium, and/or iodonium cations, and infrared absorbing cyanine anions that have two to four sulfonate groups and /or sulfate groups, and/or infrared absorbing oxonol anions. The infrared absorbing compounds can be used in aqueous developable lithographic printing plate precursors.

摘要： A thermal lithographic printing plate, which can be imaged by thermal energy typically by imagewise exposure with an infrared emitting laser, a thermal printing head, etc., is made up of a hydrophilic substrate, and a composite layer structure composed of two layer coatings. Preferably, the first layer of the composite is composed of an aqueous developable polymer mixture containing a photothermal conversion material which is contiguous to the hydrophilic substrate. The second layer of the composite is composed of one or more non-aqueous soluble polymers which are soluble or dispersible in a solvent which does not dissolve the first layer. The plate is exposed with an infrared laser or a thermal print head, and upon aqueous development of the imaged plate, the exposed portions are removed exposing hydrophilic substrate surfaces receptive to conventional aqueous fountain solutions. The unexposed portions contain the ink-receptive image areas. The second layer may also contain a photothermal conversion material. Alternatively, the composite layer may be free of photothermal conversion material when thermal imaging is carried out using a thermal printing head.

摘要： Techniques for providing accurate output measurement and calibration in soft proofing systems incorporate one or more features to promote controlled viewing conditions. For example, a soft proofing system is described in which an administator can control the proofing process by limiting or restricting the ability to view an image until acceptable viewing conditions have been met. For example, the ability to view the image can be restricted until the viewing station has been calibrated using a calibration device known to support calibration of the viewing station to less than or equal to a maximum of error. With controlled viewing conditions and, more particularly, controlled calibration conditions, the soft proof reviewers obtain more uniform output. In this manner, the system can provide safeguards to ensure that the images viewed at the viewing station have acceptable color accuracy.

摘要： The present invention provides a system for developing printing plate precursors. In one embodiment, the system includes a developer unit (115) adapted to apply developer to printing plate precursors, a replenisher unit (150) for controllably delivering replenisher to the developer unit (115) and a regenerator unit (165) for controllably delivering regenerator to the developer unit (115). The system may controllably deliver sufficient amounts of the replenisher and/or regenerator to maintain the volume and/or activity of the developer in the developer unit.

摘要： A method includes obtaining a chromatic correction for a display device based on a device-dependent display profile. The method may ensure that images that appear on a display device in a soft proofing environment will be visually equivalent to images that appear on print media.

摘要： Thermally imageable elements useful as on-press developable lithographic printing plate precursors are disclosed. The elements comprise a substrate and a layer of an imageable composition over the substrate. The imageable composition comprises a photothermal conversion material, particles of a polyurethane polymer, and, optionally, a water soluble polymer. The polyurethane polymer comprises urethane.linkages in the main chain, but does not comprise side chain urethane groups.
