Disclosed is a method for providing an ink nozzle plate with additional holes in proper locations for temporarily bonding the nozzle plate to the remaining die module or print element. Nozzle aperture plates are made from thin films such as 25 microns thick UpilexTM having holes roughly the same as or slightly smaller than the size of an ink jet channeL The holes are created by photographically patterning a photosensitive organic film or more typically by laser ablation or by punching. An adhesive layer is typically added to the frlm before laser ablation. One hole is made for each fluidic ink jet channel on the print head dye. Once the film is created, the film must be aligned to the channels so that each hole in the nozzle aperture plate is matched correctly with the corresponding ink jet nozzle. With the film in place the film can be bonded, by an adhesive, to the die face.
