20090098491 | METHOD AND APPARATUS FOR THERMAL DEVELOPMENT - This invention pertains to a method and an apparatus for thermally developing a photosensitive element, and particularly to a method and apparatus for controlling vapor and condensate created during thermal treating of the photosensitive element. | 04-16-2009 |
20090191482 | DEVICE AND METHOD FOR PREPARING RELIEF PRINTING FORM - 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 lo 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. | 07-30-2009 |
20090191483 | DEVICE AND METHOD FOR PREPARING RELIEF PRINTING FORM - The invention provides a method and an apparatus for preparing a relief printing form from a photosensitive element.

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. | 07-30-2009 |
20090288569 | PROCESS AND APPARATUS HAVING AN ADJUSTABLE HEATER - 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. | 11-26-2009 |
20090297715 | APPARATUS AND METHOD FOR TREATING A CYLINDRICALLY-SHAPED ELEMENT HAVING A CLAMP ASSEMBLY - The invention relates to an apparatus and process for treating a cylindrically-shaped element that includes means for supporting the element by contacting an interior surface of the element, means for providing a treatment medium adjacent an exterior surface of the element opposite the interior surface, and clamping means for biasing the supporting means to a preset position at one end thereof and adapted to open and close around the supporting means, or, clamping means for biasing the providing means to a preset position at one end thereof and adapted to open and close around the supporting means. | 12-03-2009 |
20100062230 | METHOD AND APPARATUS FOR THERMAL DEVELOPMENT WITH SUPPORTING SURFACE FOR A DEVELOPMENT MEDIUM - This invention relates to a method and apparatus for thermally developing a photosensitive element. The thermal development method includes heating the photosensitive element to a temperature sufficient to cause a portion of a composition layer in the element to liquefy, soften, or melt; supporting a development medium with a non-rotating surface to provide contact of the development medium with the heated photosensitive element; and providing relative movement between the development medium and the non-rotating surface. | 03-11-2010 |
