Abstract:
1. A method for preparing a relief printing form from a photosensitive element having an exterior surface and comprising a layer of a photopolymerizable composition capable of being partially liquefied, comprising the steps of: (a) heating the exterior surface of the photosensitive element to a temperature sufficient to cause a portion of the layer to liquefy, forming liquefied material; and (b) removing at least a portion of the liquefied material; wherein the heating step is performed using vibrational energy to induce frictional heating, the vibrational energy being generated from a vibrational assembly comprising a vibrating horn coupled to a transducer, the vibrating horn supporting a development medium into contact with the exterior surface of the photosensitive element, and wherein the removing step comprises separating the development medium from the photosensitive element.
