In the fabrication of aperture plates for ink jet printing machines, it is necessary to rigidly support the aperture plate. Heretofore, the aperture plate is fabricated by adhesively bonding a gold coated aperture plate to a steel reinforcing plate. The function of this joining process is to supply adequate adhesion between the plates to create a hermetic seal between individual orifices. It is difficult to bond to gold, and the adhesive layer thickness is difficult to control. The irregularity in thickness causes adhesive to flow into the orifices which will restrict the flow of ink, if not removed.
