Claims
- 1. A method of making an ink jet head having an orifice plate with an orifice extending therethrough to define a flow path for the ejection of ink, comprising the steps of:
- providing an ink jet head body having a liquid passageway for the ink with an outlet;
- adhering one surface of a photosensitive plate to the ink jet head body to cover the outlet;
- aligning a pattern mask with the liquid passageway and exposing the other surface of the photosensitive plate to radiation through the pattern mask after the photosensitive plate is adhered to the ink jet body; and
- forming the orifice through the photosensitive plate in the direction of the thickness thereof and in communication with the liquid passageway by removing portions of the photosensitive plate in accordance with the pattern of radiation to which the photosensitive plate was exposed through the mask.
- 2. A method according to claim 1, wherein the orifices are formed by exposing selected portions of the photosensitive plate to light and then removing the unexposed portions.
- 3. A method according to claim 1, wherein the photosensitive plate is a hardened film of photosensitive resin.
- 4. A method according to claim 3, wherein the hardened film of photosensitive resin is a dry film photoresist.
- 5. A method according to claim 1, wherein a plurality of orifices are formed through the plates.
