    • A system and method for producing a wide range of metallic appearances using halftones of a nano-partide metallic ink, such as, for example, nano- siiver, are presented. In exemplary embodiments of the present invention, a nano-particle metallic ink, such as, for example, nano-silver, can be made to produce a range of appearances from, for example, bright silver to dull oxidized aluminum, by changing halftone level of the silver inks, changing the substrate surface properties and introducing small amounts of other colored inks, such as process or spot, in either an underprinting or overprinting of the metallic ink. In exemplary embodiments of the present invention, InkJet printing of a single metal-pigmented ink can be effected, and its metallic appearance can very quickly be adjusted to match a given package design.
    • 提出了使用纳米级金属墨水的半色调制造多种金属外观的系统和方法,例如纳米锡。 在本发明的示例性实施例中,可以制造例如纳米银的纳米颗粒金属墨水,以通过改变半色调水平来产生例如亮银到钝化的氧化铝的外观范围 的银墨水,改变基材表面性能并引入少量其它着色的油墨,例如工艺或斑点,在金属油墨的印刷或套印中。 在本发明的示例性实施例中,可以实现单独的金属颜料墨水的喷墨打印,并且可以非常快速地调整其金属外观以匹配给定的包装设计。
