Abstract
A nozzle plate suitable for use in an ink jet printer and method of manufacturing this plate, which includes forming a plurality of grooves or serrations in the interior orifice bore surfaces of the plate. These grooves or serrations may advantageously be electroformed replications of a sculptured photoresist mask used in the electroforming process, and they serve to maximize the interior surface area of the orifice bores. This feature in turn serves to maximize frequency response, wettability, fluid flow rate, damping factor and capillarity of the nozzle plate relative to these parameters of a smooth surface orifice bore.
