Abstract

A method of forming adjacent ink and dilution solution nozzles in an orifice plate includes first providing an orifice plate having a thickness dimension. A first nozzle is then formed having a first orifice extending through the orifice plate at a first angular orientation that is generally normal to the thickness dimension. A second nozzle is then formed having a second orifice adjacent to the first orifice and at a second different angular orientation. One of the first and second nozzles is the ink nozzle and the other of the first and second nozzles is the dilution solution nozzle. The first and second nozzles are formed by laser light irradiation.
