ABSTRACT:
A high-durability printhead for an ink cartridge printing system. The printhead includes a substrate having ink ejectors (e.g. resistors) thereon and an orifice plate positioned above the substrate. The orifice plate (which preferably involves a non-metallic polymer film) has a top surface, bottom surface and a plurality of openings therethrough. To improve the durability of the orifice plate, a protective coating is applied to the top surface and/or the bottom surface of the plate. Representative coatings involve dielectric compositions (including diamond-like carbon) or at least one layer of metal. This approach improves the abrasion and deformation resistance of the plate and avoids "ruffling" and "dimpling" problems.
