A method of fabricating a long array high density nozzle plate for an ink jet printhead provides mechanical and thermal stability. A polymer is retained against a single metal laminate, or can be constrained between metal laminates, to provide the mechanical and thermal stability. Apertures are chemically etched in the one or more metal laminates. Subsequently, an axial aperture is laser ablated through a portion of the polymer layer which corresponds to the aperture through the laminates.
