ABSTRACT:
For electroplating of printing cylinders or the like, cup-like shields of non-conductive acid-resistant material are secured at opposite ends of the cylinder for rotation with the cylinder, the shields extending radially outwardly and having a configuration such as to obtain a field distribution by which the metal deposited on the surface of the cylinder is of substantially uniform thickness and density throughout the length of the cylinder.
