Abstract: The present invention describes a method for manufacturing rotogravure cylinders with a cylinder base made of aluminum and a single metallic layer on the cylinder surface. The method comprises the construction of the cylinder base, the deposition of the metallic layer on the cylinder surface, the thinning of the cylinder to achieve the required dimensions, the polishing of the cylinder surface and finally the etching of the cylinder with the desired printing pattern. The metallic layer can be any copper alloy that will produce a surface with a Vickers hardness of about 400 HV. The metallic layer is deposited onto the cylinder base using any thermal spraying method. The cylinder surface is then thinned and polished by using any conventional method. Finally, the cylinder is etched to provide a superb cylinder for the printing industry.

Abstract: Banks, as well as a plurality of recess-shaped cells defined by the banks, are provided in an image section formed in a gravure printing plate. A projecting portion is provided in each of the cells so as to protrude from a part of the base surface of that cell. The projecting portions are in positions distanced from the banks. Like the banks, the projecting portions can serve as starting points for the transfer of a printing paste. Accordingly, printing paste that would, in the case where the projecting portions are not provided, remain in the bases of the cells is transferred to the printing target material via the projecting portions, which increases the transfer efficiency. As a result, a paste film that is smooth and has the required thickness can be printed.

Abstract: The present invention relates to a refurbished cylinder roller and a process for refurbishing cylinder rollers for use in printing machines. More particularly, the present invention also relates to a process for refurbishing metallic gravure cylinder rollers by replacing the worn outer plating layers with an extruded and thermally cured electrically conductive polymer material, and thereafter electroplating new outer plating layers thereon, the new plating layers including a new printing image formed therein. The present invention also relates to a refurbished gravure cylinder roller which includes a core member extending along an axial length, an image-carrying layer having a printing image formed therein and arranged circumferentially about the core member, and an electrically conductive intermediate polymer layer arranged between the core member and the image-carrying layer, where the intermediate polymer material has a conductivity selected to permit electro-plating of the image-carrying layer directly thereon.

Abstract: A method of making rollers with a fine pattern has the acts of casting a ceramic layer onto a roller surface, grinding and polishing the roller surface, forming a pattern on the roller surface with laser, and cleaning the roller surface. Therefore, the roller thus made has a pattern with higher precision than the conventional method of mold casting. Since the roller surface has a ceramic layer that has better resistance to erosion than steel, the roller has a longer lifetime.

Abstract: A printing plate for reversed relief offset printing ensures the prevention of the internal omission of a desired pattern without increasing the depths of depressions of the plate. The printing plate comprises a base material having depressions and a non-depressed part on a surface thereof, and ink repellent layers that cover inner surfaces of the depressions, respectively. The depressions of the base material whose inner surfaces are respectively covered with the ink repellent layers have a plan shape that defines a desired pattern. The non-depressed part of the base material is formed in such a way that a part of an ink film corresponding to the non-depressed part can be transferred to the printing plate in a process of reversed relief offset printing. The parts of the ink film corresponding to the depressions are not transferred to the printing plate due to the repelling action of the ink repellent layers.

Abstract: The present invention provides a thermally sensitive composition that may be coated as a water-borne material onto a substrate to yield a printing plate precursor having an imageable coating. The thermally sensitive composition comprises a sulfated phenolic resin. The sulfated phenolic resin may be a sulfated novolak resin or a sulfated resole resin, for example. The thermally sensitive composition may include a water-soluble binder, such as polyvinyl pyrrolidone, and a radiation-absorbing component. The invention also provides a printing plate precursor that is developed in water after imaging. The precursor does not require chemical development with a developing solution containing organic solvents or inorganic additives. The imaged precursor is on-press-developable when used with a fountain solution. Methods for making and using the precursor are also provided.
