Zusammenfassung:	A printhead (103) for an inkjet print cartridge capable of generating low drop weight ink drops is produced by reducing the dimensions of the firing chamber. A thinner orifice plate (203) is needed to reliably achieve the lower drop weight ink drops. To overcome the material strength limitations of such a thinner orifice plate, an annealing step (303) in the manufacture of the printhead is employed to modify the material properties of the orifice plate. This improved process improves the print quality of printers and aids in the production handling properties of the orifice plate. Orifice plates having a thickness in the range of 25 mu m to 40 mu m are being produced.
