Abstract
A nozzle plate for ink jet cartridges which are manufactured from a relatively thin film of material, such as, for example, polyimide, polyarylene ether, or composite of a number of materials deposited on a rigid substrate, such as a silicon wafer, and photolithographically processed from the rigid substrate to produce a large quantity of interconnected nozzle plates which may be removed as a sheet of interconnected nozzle plates for ease of handling. The nozzle plates are aligned and bonded to the nozzle bearing front faces of the cartridges.
