摘要: A nozzle for an ink-jet printer is provided having a gradually converging inner diameter leading to orifice less than 15 microns in and outer proximate the at least as great other points along nozzle. The produced by heating vitreous tube (26) while rotating it, until portion of sufficiently viscous cause (70) converge angle between 5 25 degrees with respect axis symmetry tube, selected diameter. gradual taper achieved without drawing or pulling it facilitates achieving desired dimension during removal extremely small size enables deposit droplets ink make photographic-quality gray scale color images.
