    摘要： This invention relates to a method for thermally developing a photosensitive element to form a relief pattern. The method includes heating a composition layer of the element to cause a portion of the layer to liquefy and providing a development medium under tension to the element to absorb the liquefied composition. The development medium includes an absorbent material and a support, the combination of which minimizes stretch and distortion of the absorbent material and can impede the migration of the liquefied composition through the absorbent material.

    摘要： This invention provides an apparatus and process for forming a printing form from a photosensitive element having an exterior surface and a composition layer capable of being partially liquefied. The apparatus includes a displaceable heater for heating the composition layer, means for removing at least a portion of the composition layer from the element, and means for displacing the displaceable heater to a predetermined distance from the exterior surface. Positioning the displaceable heater at the predetermined distance assures reproducible removal of the liquefied composition from the various types of photosensitive elements that can be thermally treated in the apparatus, resulting in the printing forms having improved relief surface uniformity.

    摘要： The invention provides a method and an apparatus for preparing a relief printing form from a photosensitive element. More specifically, this invention describes a method and an apparatus for preparing a relief form in an environment having controlled oxygen concentration during exposure to actinic radiation. The method includes forming an in-situ mask on a 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 190,000 and 100 ppm, and treating the exposed element to form the relief printing form having a pattern of raised surface areas.
