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.
