The deposit of hard copper plating has the advantages of fine grained structure, small internal stress, excellent ductility and flexibility. The hardness of the plating layer is high, which can reach to 240HV. The current density is wide and the plating solution is stable and easy to control. As the surface is smooth after plating and the performance is good, it can save the polishing time effectively. The copper layer is with smoothness and high hardness, which makes it suitable for plating gravure cylinders and plate in intaglio printing.
The hard copper plating process is a stable new process for gravure cylinders and plate in intaglio printing.
