  • Digitally exposable flexographic printing element and method for producing flexographic printing plates
    Patent number: 9789679
    Abstract: Digitally imagable flexographic printing elements for producing flexographic printing plates, which comprise an organically soluble relief-forming layer, a water-soluble barrier layer for oxygen, and a water-soluble laser-ablatable mask layer. A method for producing flexographic printing plates using such flexographic printing elements, which comprises a two-stage washout procedure using aqueous and organic washout media.
    Type: Grant
    Filed: September 18, 2014
    Date of Patent: October 17, 2017
    Assignee: Flint Group Germany GmbH
    Inventors: Uwe Stebani, Armin Becker, Matthias Beyer, Denis Riewe, Andreas Reifschneider
  • Flexographic printing element which can be digitally imaged and has a polar, ultra-thin barrier layer
    Patent number: 9671696
    Abstract: Digital imageable flexographic printing elements for producing flexographic printing plates, which are developable using hydrocarbon-comprising washout media and which, between the photopolymerizable layer and the digital imageable layer, have a polar, ultrathin, oxygen-blocking barrier layer. Methods for producing flexographic printing plates using such digital imageable flexographic printing elements, by imaging, exposing, washing out, drying, and post-treating, the washout being formed by means of hydrocarbon-comprising washout media.
