Abstract
An inkjet printhead includes a nozzle plate formed of a polymer material that has been photoablated or photo-etched to form inkjet nozzles. The polymer material preferably is a plastic such as teflon, polyimide, polymethylmethacrylate, polyethyleneterephthalate or mixtures thereof. The nozzle plate also has formed in it a plurality of vaporization chambers. The inkjet nozzles are preferably formed in a flexible strip of polymer film by masked laser radiation, where the mask is physically spaced from the polymer film. Heater resistors may be formed on the nozzle plate within each of the vaporization chambers.
