<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 inkcarrying 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> |
