Abstract

A method of making an ink jet head with an orifice plate having an orifice extending therethrough for ink ejection involves the steps of adhering a photosensitive plate to the ink jet head to cover the outlet of a liquid passageway in the head, aligning a pattern mask with the ink passageway, exposing the photosensitive plate in-situ to radiation through the pattern mask, and removing portions of the photosensitive plate in accordance with the radiation pattern to form in the photosensitive plate an orifice aligned with the outlet.
