  • Process for preparing a photopolymerizable printing element
    Patent number: 5653929
    Abstract: A process for preparing a photopolymerizable printing element includes feeding a layer of a photopolymerizable composition, calendering the layer to form a web, applying tension to the web, and cooling the web wherein during cooling, a gripping force is applied at side edges of the web. The application of the gripping force to the web substantially reduces non-uniformities in the thickness of the photopolymerizable layer.
