Abstract:
1. A method for integrally fabricating an orifice array plate and a charge plate for a continuous ink jet printer print head, said method comprising the steps of: providing an electrically non-conductive substrate, wherein the electrically non-conductive substrate includes one side and the other side opposite to the one side; providing a layer of conductive metal on the one side and on the other side of the electrically non-conductive substrate; forming, on the one side of the electrically-nonconductive substrate, an orifice plate with an array of orifices; forming, on the other side of the electrically-nonconductive substrate, an ink droplet charging charge plate comprising respective ink droplet charging charge leads each aligned with a corresponding one of the orifices; and further comprising a step of removing portions of the layer of conductive metal from around each of the orifices and between the ink droplet charging charge leads.
