LAMINATE AND METHOD FOR PRODUCING PRINTING PLATE
A method for producing a laminate. The method includes providing a support, a printing original plate, and a protection film to form the laminate. A photosensitive resin is cured through an entire surface exposure on a surface of the printing original plate facing the protection film to form a cured resin of the printing original plate. The surface of the printing original plate is laser engraved with an ultrashort pulsed laser beam to form an indented pattern on the surface of the printing original plate. The printing original plate has a storage modulus G of 5.00?10.sup.4 Pa or more and 1.00?10.sup.6 Pa or less at 140? C.

PRINTING PLATE, SUBSTRATE, AND PRINTING METHOD
A printing plate having a recessed area to be filled with a print material to be transferred to a substrate includes at least one step situated in at least part of the recessed area and having a different depth than a bottom face of the recessed area.
Method for producing decorative prints having identical quality independently of the printing method used and a device for performing said method
A method for producing decorative prints having identical quality on at least two carrier materials includes the following steps: providing at least one print motif; converting the at least one print motif into at least one high resolution electronic data set; reducing the resolution of the at least one high resolution electronic data set; creating at least one first print decor on at least one first carrier material by means of the at least one resolution reduced electronic data set; creating at least one print cylinder for a gravure printing process by using at least one resolution reduced electronic data set, with the resolution reduced electronic data set identical to or different from the resolution reduced electronic data set used for the digital printing; and creating at least one second print decor on at least one second carrier material by using the at least one print cylinder.
FLEXOGRAPHIC PRINTING PLATE
An object of the present invention is to provide a flexographic printing plate having excellent ink transferability in a solid portion and the like and having good printing quality in a halftone portion. The flexographic printing plate of the present invention is a flexographic printing plate having a relief layer including a non-image area and an image area, in which the image area has a halftone dot portion having a halftone dot area ratio of more than 0% and less than 100%, and a solid portion having a halftone dot area ratio of 100%, small dots in the halftone dot portion and the solid portion or small dots in the halftone dot portion have two or more recessed portions having different depths according to a halftone dot area ratio, and the two or more recessed portions having different depths are recessed portions whose depth becomes deeper as the halftone dot area ratio increases.

LASER-ENGRAVABLE PAD PRINTING PLATE
A laser-engravable pad printing plate comprising at least (a) a metal support, (b) an adhesion layer, (c) a laser-engravable recording layer having a layer thickness of 20 ?m to 200 ?m, (d) a cover film,
characterized in that the laser-engravable recording layer (c) comprises (c1) 40 to 95 wt % of a polyvinyl alcohol, (c2) 5 to 50 wt % of an IR absorber, (c3) 0 to 30 wt % of an inorganic filler, (c4) 0 to 20 wt % of a crosslinker, and (c5) 0 to 10 wt % of further additives.

POLYMERIC GRAVURE PRINTING FORM AND PROCESS FOR PREPARING THE SAME WITH CURABLE COMPOSITION HAVING A MULTIFUNCTIONAL URETHANE
The invention pertains to a printing form and a process for preparing a polymeric printing form from a curable composition that includes a multifunctional urethane in a specified reactive group equivalent weight range, and an initiator. The process includes coating the curable composition onto a supporting substrate, such as a print cylinder, to form a layer, curing the layer with heat or by exposure to actinic radiation, and engraving the resulting cured layer to form at least one printing cell in the cured layer. The process prepares novel polymeric printing forms, particularly novel polymeric gravure printing forms, having a cured polymer-based composition layer that is engravable, resistant to solvent inks, and capable of printing gravure-quality images. The present invention shortens the time to prepare gravure printing cylinders and removes the need for and disposal of toxic heavy metals such as copper and chrome associated with conventional gravure print cylinder preparation.
