Abstract
An orifice plate for use in ink jet printing machines is produced by an electroplating technique. The plate is bilaminar with nickel being plated onto copper to form a substantially rigid structure.
Claims15
A method of producing an orifice plate for use in an ink jet printing system, including the steps of:
- providing a thin substrate attached to a thick support;
- forming a pattern of electrically insulated areas on the surface of the substrate opposed to the support;
- electroplating the uninsulated areas of the surface of the substrate opposed to the support;
- separating the substrate from the support;
- forming a pattern of chemically resistant areas on the nonelectroplated surface of the substrate to protect selected areas thereof;
- and
- dissolving the non-protected areas of the substrate to produce an orifice plate.
