ABSTRACT:
Nozzles in an ink jet printhead nozzle plate are laser formed into the nozzle plate at a spacing differing from that of the corresponding ink heating elements by a function of the thermal expansion characteristics whereby heating of the nozzle plate to activate a heat set adhesive for securing the nozzle plate to the heating element substrate expands the nozzle plate thereby aligning the nozzle axes with the corresponding heating elements.
