Beschreibung
Zusammenfassung:	The present invention relates to an intaglio printing plate, comprising a metallic substrate and a protective coating deposited on the substrate by physical vapor deposition. The protective coating consists of a functionally graded material comprising a ceramic phase and a metallic phase, wherein the ceramic phase is harder than the metallic phase, and wherein the percentage of the metallic phase within the functionally graded material increases in a direction towards the substrate.
