Abstract
A method for fabricating an ink jet droplet generator. According to the disclosed technique, a metallic body is first machined to define one or more ink receiving cavities and to further define an intended nozzle surface. Resist material is applied to the nozzle surface at the intended ink nozzle positions and a thin metallic plating formed on the surface. The resist and body are then etched to form one or more passageways from the ink cavities past the regions formerly occupied by the resist. These passageways form the generator nozzles.
