Abstract: The deposition and drying out of ink on the front surface of a print head nozzle plate adversely affects the ejection of the ink droplets. The nozzle plate (12) of ink wettable material carries a coating (30) on its front surface on non-wetting material. Such arrangement provides a stable meniscus of the ink column in each nozzle (24) and prevents ink from depositing at the front surface around the nozzle orifice. The principal use is in an ink jet printer.

Abstract translation: 在打印头喷嘴板的前表面上的墨的沉积和干燥不利地影响墨滴的喷射。 油墨可润湿材料的喷嘴板（12）在非润湿材料的表面上带有涂层（30）。 这种布置在每个喷嘴（24）中提供了墨柱的稳定的弯月面，并且防止墨水在喷嘴孔周围的前表面沉积。 主要用途在喷墨打印机中。
