A gravure printing system comprising a gravure cylinder having a first plurality of discrete cells disposed upon an outer surface thereof is disclosed. Each cell of said first plurality of discrete cells has a nominal diameter and is capable of receiving a fluid that is a first combination of at least two primary fluids. The fluid is fluidically displaceable through a discrete channel having a single entry point at said first position and a single exit point into a first cell of said first plurality of discrete cells. The outer surface has a metal plating disposed thereon. The metal plating reduces the nominal diameter of each cell of the first plurality of discrete cells.

A printing roller for a printing machine, e.g., for a flexographic printing machine, wherein the printing roller includes a rotary and longitudinal axis and an external surface, the external surface being substantially cylindrical and adapted for mounting a plate. The new feature of a printing roller according to the invention is that the external cylindrical surface includes at least one longitudinal groove, where the at least one longitudinal groove includes a geometry with one or more surfaces, the surface or surfaces lying within a circumscribed cylindrical surface for the external surface of the printing roller. In other words, this means that the longitudinal groove or grooves are cutouts in the form of milled or ground grooves in the external cylindrical surface itself on a printing roller.

A method for manufacturing rotogravure cylinders with a cylinder base made of aluminum. The method involves the coating of the cylinder surface with high velocity spraying, the copper plating in an appropriate solution, the engraving of the cylinder, and the hardening of the cylinder by chromium plating. The spraying process is accomplished by High-Velocity Air-Fuel or High-Velocity Oxygen-Fuel thermal spraying which leads to less surface porosity, better adhesion of the copper substrate and better dimensional accuracy.
