Abstract
In a method of making an ink jet printhead, corrugations are formed by laser ablation in the bonding surface of a polymer nozzle plate. Adhesive is applied to the micro-cavities thus formed and the nozzle plate is pressed against the end surface of the printhead until the surface lands in the nozzle plate abut on the surface of the printhead.
