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 to a temperature sufficient to cause a portion of the layer to liquefy and form liquefied material; and (b) contacting the photosensitive element with a development medium to allow the liquefied material to be removed by the development medium; wherein the heating step is performed using a jet of heated fluid emitting from a nozzle assembly at a velocity of 10 to 35 meter/second and temperature of 110° C. to 350° C., and impinging the exterior surface at a heat flux greater than or equal to 10 kiloWatts/m
