Abstract
A relief printing form is prepared from a photosensitive element. An in-situ mask is formed and disposed above a photopolymerizable layer of the photosensitive element, the element is exposed to actinic radiation through the in-situ mask in an environment having an inert gas and a concentration of oxygen between about 30,000 ppm and about 7500 ppm to form at least a polymerized portion and an unpolymerized portion of the layer, and the exposed element is processed by treating with at least one washout solution selected from solvent solution, aqueous solution, semi-aqueous solution, or water.
