  • Method for preparing a printing form
    Patent number: 8198013
    Abstract: The invention pertains to a method for preparing a printing form from a photosensitive element having a support and a layer of photopolymerizable material adjacent the support. The method includes exposing the photosensitive element through an image mask and through a backside mask, treating the exposed element to form a relief region and to provide an unexposed region of the photopolymerizable material remaining on the support, and removing the unexposed region from the relief region, wherein the relief region remains on the support as the printing form. The method is particularly suited for preparing a composite printing form from the printing form, and in particular for preparing composite printing forms for relief printing of corrugated substrates.
