Abstract: A method of forming a nozzle plate component for a printhead comprising the steps of: providing a laminar body having a polymeric upper layer defining a top surface and a metal lower layer defining a bottom surface; removing material by ablation or photolithography from the polymeric layer to selectively expose the metal layer; and applying etchant from the top surface that selectively etches the exposed areas of the metal layer, thereby undercutting said upper layer to form a recess area in the metal layer and forming an opening through said body.
