Abstract
An imageable support matrix for printhead nozzle plates and a method for manufacturing the printhead. The ink jet printhead comprises a substrate including an ink via therein; a first layer of imageable material, the first layer of imageable material having ink conducting voids therein and defining support structures adjacent the ink via; and a second layer of imageable material disposed on the first layer of imageable material, the second layer of imageable material including ink jet nozzles therein. The method includes providing a substrate; applying a first layer of imageable material on the substrate; masking the applied first layer of imageable material; and developing the masked first layer of imageable material to provide ink conducting voids in the first layer of imageable material and hardened areas of support. The method further includes creating an ink via in the substrate; applying a second layer of imageable material on the first layer of imageable material; and forming nozzles in the second layer of imageable material.
