  • METHOD FOR PRODUCING AN OPTICALLY VARIABLE IMAGE CARRYING SHIM
    Publication number: 20110033664
    Abstract: The present invention relates to a method for producing a duplicated shim and the duplicated shim obtainable by the method. The duplicated (UV-cured) shim, independent of any carrying device (like a cylinder or belt), can be applied directly to the surface of the transfer roller (and impart the surface OVD structure into a clear lacquer) in a similar way to conventional nickel shims.
