Abstract
The present invention provides a method and apparatus for forming a printing form from a photosensitive element to form a relief pattern. The method and apparatus thermally develop the photosensitive element by heating a composition layer of the element to cause a portion of the layer to liquefy and providing a development medium to the element to remove the liquefied composition. A conformable layer is disposed between the photosensitive element and a base support, which improves the compressibility and the contact between the photosensitive element and the development medium. The method and apparatus improve the efficiency of the removal of liquefied portions from the photosensitive element and the uniformity of the relief pattern formed.
