Abstract
An ink jet printhead includes a nozzle plate including a nozzle, a recess in the nozzle plate, and a compliant layer that covers the recess and forms a sealed pocket that may be filled with air or another gas during use of the printhead. During actuation of a piezoelectric element during the ejection of ink from the nozzle, the sealed pocket attenuates an acoustic energy generated by the piezoelectric element, thereby reducing crosstalk to adjacent nozzles by the acoustic energy.
