Chrome:
The Chrome plating process uses the Chrome-Plating tank from abroad to place a layer of Chrome on to the cylinder to give the maximum life to the engravured cylinders. In addition to the plating, a tank based on the latest knowledge and technology in the rotogravure-electroplating field constructed with the latest materials, gives the hardness of 900–1000 Vickers. Controlled electrolyte flow and perfect temperature control give the cylinder a constant hardness all through.
