A method is provided for forming a charge plate (10) for an ink jet printing device which includes coating a relatively more difficult to deplate metal layer (24) on a relatively easier to deplate core wire (22), mounting a plurality of the coated wires (20) in spaced parallel relation on a nonconductive support plate (12) and attaching leads to the metal layer (24) and then deplating the core wire (22) to leave the coating to form charge tunnels in the charge plate defining cylindrical holes through which droplets of printing liquid can pass to be charged by the electrodes.
