To obtain good directional accuracy from thermal ink jet printheads, the front face in the nozzle region should be ink repellent. Directional accuracy of drop placement is needed to print high quality characters and generate artifact free halftone images. One method of making the font face around the nozzles repellent is to apply a thin coat of some low surface energy material such as a silicone resin or a fluorinated silane to the front face.
