Abstract:

An orifice array plate and a charge plate for a continuous ink jet printer print head are integrally fabricated by providing an electrically non-conductive substrate; forming, on one side of the substrate, an orifice plate with an array of orifices; forming, on the other side of the substrate, a charge plate comprising a plurality of charge leads aligned with respective ones of the orifices; and removing at least that portion of the substrate that is between the orifices and the charge leads. The final produce includes an electrically non-conductive substrate; an orifice plate, including an array of orifices, on one side of the substrate; a charge plate, including a plurality of charge leads, on the other side of the substrate such that the charge leads are aligned with respective ones of the orifices; and a plurality of passages through the substrate, said passages extending between the orifices and the charge leads.
