ABSTRACT:
An electrohydrodynamic stimulated ink jet printing device and method of manufacture which eliminates the prior art problem of ink wetting the dielectric spacer between the stimulating electrode and the ink jet nozzles. The nozzles are electroformed on one side of a sheet of dielectric material and the EHD electrodes are electroformed on the other side of the dielectric material in registration with the nozzles. The dielectric material is removed from the nozzles by using the nozzles or the electrodes as masks. The internal surface of the dielectric material is coated with a one of a number of coatings non-wettable by the ink such as a mixture of paraffin and ethylene vinyl acetate copolymer dissolved in a light aliphatic hydrocarbon, such as VMP naphtha.
