摘要： The present invention provides a thermally sensitive composition that may be coated as a water-borne material onto a substrate to yield a printing plate precursor having an imageable coating. The thermally sensitive composition comprises a sulfated phenolic resin. The sulfated phenolic resin may be a sulfated novolak resin or a sulfated resole resin, for example. The thermally sensitive composition may include a water-soluble binder, such as polyvinyl pyrrolidone, and a radiation-absorbing component. The invention also provides a printing plate precursor that is developed in water after imaging. The precursor does not require chemical development with a developing solution containing organic solvents or inorganic additives. The imaged precursor is on-press-developable when used with a fountain solution. Methods for making and using the precursor are also provided.

摘要： A method of patterning a perforated screen printing screen (9) having a lacquer coating filling its perforations (10), using a laser engraving device, includes the steps of locating the position of the locus of aligned perforations (10), aligning an engraving head (7) of the laser engraving device with the locus of the perforations (10) and then selectively actuating the laser to remove the lacquer individually from those perforations (10) which it is required to unblock. The laser engraving device includes a scanner (1,2) for scanning the laser engraving head (7) over the surface of the screen (9), a detector (8) for detecting the locus of the perforations (10) extending in the scanning direction of the laser engraving head (7) and the location of each perforation (10) in the scanning direction, alignment devices (4, 5, 6) responsive to the output of the detector (8) to align the laser engraving head (7) with the locus of the perforations (10) detected by the detector (8), and a laser actuation control (20, 21, 24) to enable the laser to be actuated only when it is aligned with the individual perforations (10).

摘要： A roto-gravure printing base cylinder is made by providing a cylindrical body (1), for example of steel, and applying thereover a cover layer (2) by thermal spraying, for example plasma-spraying, or arc-spraying. The cover layer is made of a material which is inert with respect to electrolytes used in applying a further copper layer over the cover layer to form a finished roto-gravure cylinder for optical engraving, for example an electrochemical valve metal, preferably tantalum, niobium or, most desirably, titanium oxide, forming a matrix in which, before application of the material as a layer on the steel cylinder, electrochemically active materials are applied made of a metal, preferably of the platinum group or other noble metal, and uniformly distributed over the surface, settled on the matrix material.
