A plastic orifice plate (43) for an ink jet printhead and manufacturing process therefor which includes electroforming a metal die (22) having raised sections (30) thereon of predefined center-to-center spacings, and using the die to punch out openings (32) in a plastic substrate of a chosen thickness to form a plurality of closely spaced orifice openings (36) in the substrate. The orifice plate (43) 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.
