Abstract
The invention provides a method for preparing a relief printing form from a photosensitive element. The method includes forming an in-situ mask disposed above a photopolymerizable layer of the photosensitive element, exposing the element to actinic radiation through the in-situ mask in an environment having an inert gas and a concentration of oxygen between about 50,000 ppm and about 2000 ppm to form at least a polymerized portion and an unpolymerized portion of the layer, and treating by heating the exposed element to a temperature sufficient to cause the unpolymerized portion to melt, soften, or flow.
