A plastic orifice plate for an ink jet printhead and manufacturing process therefor which includes electroforming a metal die having raised sections thereon of predefined center-to-center spacings, and using the die to punch out openings in a plastic substrate of a chosen thickness to form a plurality of closely spaced orifice openings in the substrate. The orifice plate can be of a chosen transparent material and secured to a printhead substrate where the dynamics of ink flow can be viewed through the orifice plate during printhead testing and evaluation.

A process for forming an orifice plate for an ink jet printhead which comprises: a. providing a metal die having raised contoured convergent mesa-shaped sections therein with predefined center-to-center spacings which define desired corresponding center-to-center spacings of orifice openings in an ink jet orifice plate, b. bringing said die into physical contact with a preform of a preselected material and thickness so that said raised sections of said die punch through said preform and thereby form contoured convergent orifice geometries therein, and c. removing said preform from said die and exposing said preform to a plasma reaction to remove flashing from the punched-formed orifice openings therein.
