    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.

    摘要： The present invention relates to IR-sensitive compositions suitable for the manufacture of printing plates developable on-press. The IR-sensitive compositions comprise:(a) a first polymeric binder which does not comprise acidic groups having a pKa value less than or equal to 8;(b) a second polymeric binder comprising polyether groups(c) an initiator system comprising(i) at least one compound capable of absorbing IR radiation selected from triarylamine dyes, thiazolium dyes, indolium dyes, oxazolium dyes, cyanine dyes, polyanifne dyes, polypyrrole dyes, polythiophene dyes and phthalocyanine pigments;(ii) at least one compound capable of producing radicals selected from polyhaloalkyl-substituted compounds; and(iii) at least one polycarboxylic acid represented by the following formula IR4-(CR5R6)r - Y - CH2COOH (I) wherein Y is selected from the group consisting of O, S and NR7,each of R4, R5 and R6 is independently selected from the group consisting of hydrogen, C1-C4 alkyl, substituted or unsubstituted aryl, -COOH and NR8CH2COOH,R7 is selected from the group consisting of hydrogen, C1-C6 alkyl, -CH2CH2OH, and C1-C5 alkyl substituted with -COOH,R8 is selected from the group consisting of -CH2COOH, -CH2OH and -(CH2)2N(CH2COOH)2 and r is 0, l, 2 or 3, with the proviso that at least one of R4, R5, R6, R7 and R8 comprises a -COOH group or salts thereof, and(d) a free radical polymerizable system comprising at least one member selected from unsaturated free radical polymerizable monomers, oligomers which are free radical polymerizable and polymers containing C=C bonds in the back bone and/or in the side chain groups,wherein the following inequality is met:oxi

    摘要： The invention is directed to various calibration techniques for calibrating an imagining device such as a display device, a printer, or a scanner. The techniques may involve characterizing the imaging device with a device model such that an average error between expected outputs determined from the device model and measured outputs of the imaging device is on the order of an expected error, and adjusting image rendering on the imaging device to achieve a target behavior. The invention can achieve a balance between analytical behavior of the imaging device and measured output. In this manner, adjustments to image rendering may be more likely to improve color accuracy and less likely to overcompensate for errors that are expected.

    摘要： In general, the invention provides scaling tools for compensating for scaling variations between two printing systems, such as an analog printing system and a digital printing system. An operator designates one of the systems as the reference printing system and the other printing system as the scalable printing system. The operator constructs a reference grid (10) with the reference printing system and a scaling grid (30) with the scalable printing system. By comparing the reference grid and the scaling grid, the operator finds one or more scaling factors (52, 66), which the operator may use to set the scale of the scalable printing system. The operator may print an image using the reference printing system and the scalable printing system, and the scalable printing system prints to the same scale as the reference printing system.
