<p>A method of forming an outwardly tapered orifice (16) for a fully assembled ink jet printhead (10). A main body (12) portion and a cover plate (14) for an ink jet printhead (10) are mounted together such that the cover plate (14) covers an ink-carrying channel (22) which axially extends through the main body portion (12). First and second light beam capable of ablating the material used to form the cover plate (14) is generated and an ink-carrying channel (22) communicating orifice extending through the cover plate (14) and tapering outwardly from a front side of the cover plate (14) to a back side (14a) of the cover plate (14) is formed by directing the first and second light beams at the front side (14b) of the cover plate (14) at first and second angles, respectively, whereby the first and second light beams form the outwardly tapered orifice (16).</p> |
