The method includes forming an in-situ mask having a line screen resolution equal to or greater than 250 lines per inch on the photosensitive element, exposing the element to actinic radiation through the in-situ mask in an environment having an inert gas and a concentration of oxygen between 190,000 and 100 ppm, and treating the exposed element to form a relief structure having a plurality of raised surfaces with a line screen resolution equal to or greater than 250 lines per inch. Printing is accomplished by applying an imaging material to the plurality of raised surfaces and contacting to transfer the imaging material to the substrate. The method is suitable for printing high resolution graphic images, as well as for forming a uniform layer of imaging material on the substrate.

  • Patent number: 8857332
    Abstract: The invention relates to an aluminum alloy strip for the production of printing plate carriers comprising water-based coatings, wherein the aluminum alloy strip has a thickness of at most 0.5 mm. The object is to propose an aluminum alloy strip for the production of printing plate carriers comprising at least one water-based coating so that punctiform coating faults are prevented. The object is achieved for an aluminum alloy strip in that the aluminum alloy strip, in a longitudinal polished section prepared using water as a lubricant, has etch figures with a cubic etching, of which the longitudinal extent is at most 15 mm.

  • Publication number: 20140299010
    Abstract: Printing blankets having non-extensible backing plies such as, for example, metalback blankets, are provided which have a construction that is adapted to be mountable onto blanket cylinders having a gap containing a conventional single reel rod lock-up mechanism. The blankets include first and second relief areas positioned such that when the blankets are mounted onto a blanket cylinder, the relief areas substantially align with the point at which the lead and trail ends of the blankets are inserted into a gap in the blanket cylinder to secure the ends in the lock-up mechanism.
