Abstract: An intermediate rotogravure product has a cylindrical case onto which a circumferential copper layer extends, the circumferential copper layer having a characteristic surface roughness Rz and porosity. A copper engraving layer is on the circumferential copper layer. A method for engraving into adds a copper engraving layer, followed by engraving a predetermined pattern. A rotogravure cylinder product and method add a copper engraving layer on the circumferential copper layer that can be engraved in accordance with a predefined pattern and protected with a protection layer.

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: The rotogravure cylinder comprising a rotary gravure base and thereon a copper engraving layer is refurbished to contain a zinc layer between a gravure base and a layer package suitable for engraving and printing. This layer package for instance comprises a metallic support layer, a copper engraving layer and suitably a protection layer. Deposition of the zinc layer may be tuned for thickness variation, in combination with deposition of the layer package in a fixed thickness.
