摘要：
A relief printing form is prepared from a photosensitive element in an environment having controlled oxygen concentration during exposure to actinic radiation. An in situ mask is formed on a 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 190,000 and 100 ppm, and the exposed element is treated to form the relief printing form having a pattern of raised surface areas.
