Abstract A method for making an orifice plate (40) for an ink-jet printer. The orifice plate defines both the orifices (42, 44) and the connected ink chambers (60, 62). The orifice plate is constructed to permit, in the same print head (26), one chamber (or orifice) to be deeper (as well as, if desired, wider and longer) than another chamber (or orifice) that may be next to the first chamber. Similarly, a channel (64) delivering ink to the first chamber (60) may be configured to be deeper or shallower, as needed, relative to another channel (66) in the orifice plate.
