摘要： Apparatus and methods for imaging lithographic plates using laser devices that emit in the near-infrared region, and plates suitable for imaging with the apparatus and methods. Laser output either ablates one or more plate layers or physically transforms a surface layer, in either case resulting in an imagewise pattern of features on the plate. The image features exhibit an affinity for ink and/or a fluid to which ink will not adhere that differs from that of unexposed areas.

摘要： Seamless, sleeve-shaped dry and wet lithographic printing members that can be recycled after use are disclosed, along with methods for their manufacture and use. The members include a strong, durable, hollow cylinder or sleeve that is attached to the plate mandrel or cylinder jacket of an offset printing press or platemaking apparatus. Surrounding the sleeve is a layer of a material, preferably polymeric in nature, which is characterized by efficient, ablative absorption of laser radiation, as well as other layers that facilitate imaging and subsequent printing. A layer disposed beneath the ablatable layer reflects unabsorbed imaging radiation back into the ablatable layer.

摘要： A method of and apparatus for imaging a lithographic plate having a printing surface by exposing the printing surface to plasma jet discharges between the plate and a plasma jet nozzle spaced close to the printing surface of the plate. These plasma jet discharges are sufficient to ablate or otherwise transform one or more layers of the printing surface, thereby changing the affinity of the printing surface for ink and/or water at the points thereof exposed to the discharges so as to produce image spots on the plate.

摘要： A method of imaging a lithographic plate having a printing surface comprises exposing the printing surface to plasma jet discharges between the plate and a plasma jet nozzle spaced close to the printing surface of the plate. These plasma jet discharges are sufficient to remove a layer or layers of the plate to thereby change the affinity of the printing surface for ink and/or water at the points thereof exposed to the discharges, thereby producing image spots on the plate.

摘要： A printing member for a press without dampening made by forming on a metal substrate an organic plastic layer having an exposed surface which is highly oleophobic and thermally decomposing the layer surface at selected image points thereon without contacting the surface and without penetrating through the layer so that there is a transformation of the surface structure which renders said surface oleophilic at said image points.

摘要： Techniques for imaging lithographic printing members responsive to the output of laser devices. Laser output passes through at least one discrete layer and ablates one or more underlying layers, resulting in an imagewise pattern of features on the printing member. The image features exhibit an affinity for ink or an ink-abhesive fluid that differs from that of unexposed areas.

摘要： Seamless, sleeve-shaped dry and wet lithographic printing members that can be recycled after use include a strong, durable, hollow cylinder or sleeve that is attached to the plate mandrel or cylinder jacket of an offset printing press or platemaking apparatus. In one version, the sleeve is surrounded by a photopolymer, which is itself surrounded by a mask coating opaque to radiation that is actinic with respect to the photopolymer. Subsequently, the imaged construction is exposed to actinic radiation, and the unexposed photopolymer, along with the overlying mask, is removed by ordinary chemical means. In another version, a thermally transferable material surrounds a cylinder, and is itself surrounded by a withdrawal layer. Exposure of the thermally transferable layer to laser radiation adheres the transferable layer to the cylinder, and the adhered layer exhibits an affinity for fountain solution and/or ink opposite to that exhibited by the cylinder. The withdrawal layer is then peeled away, leaving exposed portions adhered to the cylinder.
