ABSTRACT:
An inkjet printhead with first and second nozzle plates. The first nozzle plate is comprised of a first material spanning a plurality of nozzles. The first nozzle plate has a plurality of cavities filled with a filler such that an upper surface of the first nozzle plate and an upper surface of the filler together define a contiguous planar surface. The second nozzle plate is comprised of a second material disposed on the planar surface.
