Abstract
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.
