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.

A gravure printing roll that enables printing of fine dots with a size close to that of cells and enables printing on a print subject, such as a printing substrate, without changing the appearance of the print subject. The gravure printing roll includes: a gravure printing roll body; and cells formed in a peripheral surface of the gravure printing roll body. Each of the cells has an opening with a ratio between a dimension in a circumferential direction of the gravure printing roll body and a dimension in an axial center direction of the gravure printing roll body (dimension in the circumferential direction/dimension in the axial center direction) being 1.15 to 7, and have an opening area of 3900 m.sup.2 or smaller.

A gravure roll, in which the outside peripheral surface of a metal roll main body has a plurality of oblique line shaped protrusions forming a prescribed angle with the center axis of the roll main body and the coating liquid can be held in a plurality of oblique line shaped recesses formed between each of the plurality of protrusions, is configured such that the roll main body has a diamond-like carbon layer on the entire outer peripheral surface thereof, a head part for each of the plurality of protrusions is cut down, and each of the plurality of protrusions has a trapezoidal cross-sectional shape that becomes gradually narrower in width moving in direction toward the head part. A separator with a uniform weight per unit area can be manufactured wherein the coating liquid is coated onto a base material film using this gravure roll.

Provided are a seamless cylindrical offset printing plate which enables seamless continuous printing to be performed, a manufacturing method therefor, and a reproduction processing method. The seamless cylindrical offset printing plate comprises: a cylindrical plate base material; a hydrophilic satin-like rough surface which is formed on a surface of the cylindrical plate base material; and a hydrophobic resist pattern part which is formed on the satin-like rough surface, wherein an exposed part of the satin-like rough surface serves as a non-printing area and the resist pattern part serves as a printing area.

A method for manufacturing and regenerating a functional surface of an anilox sleeve or anilox roller for a printing machine with a coating protecting against wear and corrosion. The anilox sleeve is preferably made out of a lightweight plastic on which an intermediate layer is applied and has a metal tube located above the intermediate layer. During a first phase, the worn engraving and the old layer are ground off from the cylindrical surface of the anilox sleeve, that is to say from the metal tube, and a coating, a carbidic tungsten carbide-cobalt-chromium layer (WCCoCr) is subsequently applied. This carbidic layer is applied by a high-speed flame spraying (HVOF) process and subsequently functionalized by laser.
