Abstract: There is described a method for forming an ink jet print head. The method includes providing a printhead including a nozzle plate having a plurality of apertures and coating an anti-wetting composition on a surface of the nozzle plate while the plurality apertures in the ink jet aperture plate are maintained at a first pressure such that a plurality of menisci of the composition form over the plurality of apertures. The plurality of menisci are purged by increasing the first pressure at the plurality of apertures to a second pressure greater than the first pressure. The anti-wetting composition is cured. An apparatus for applying the coating is described.
