    • The present invention provides a 100% solids Uv curable ink. A 100% solids Uv curable ink should emit substantially less VOCs than an organic solvent-based ink because the components of the solids ink are intended to become part of the Uv cured product. An ink for one embodiment of the present invention can comprise more than one resin, a photoinitiator, a carrier medium; and a colorant. Preferably the one polymerizable resin is a highly functional resin and another polymerizable resin is a low functional resin. One resin may be high viscosity and the other low viscosity. The ink could be suitable for use in a drop on demand print system such as with a piezoelectric printer. Further, certain aspects of the invention provide a method for formulating an ink by combining a polymerizable resin, a photoinitiator, and a colorant in a carrier medium. Such an ink can be jetted onto a substrate and cured with ultra violet radiation. The jetting and curing of the ink can be caused by an ink jet printhead with an ultra violet lamp attached to the printhead. This lamp-printhead can be used in an ink jet printer. Other aspects of the present invention include a multicolor ink sets.
    • 本发明提供100%固体的Uv可固化油墨。 由于固体油墨的成分旨在成为Uv固化产品的一部分,100%固体的Uv可固化油墨应该比有机溶剂型油墨显着减少VOC。 本发明的一个实施方案的油墨可以包含多于一种树脂,光引发剂,载体介质; 和着色剂。 优选地,一种可聚合树脂是高官能树脂,另一种可聚合树脂是低官能树脂。 一种树脂可能是高粘度和另一种低粘度。 墨水可以适用于诸如用压电打印机的点播打印系统中使用。 此外,本发明的某些方面提供了通过在载体介质中组合可聚合树脂,光引发剂和着色剂来配制油墨的方法。 这样的墨水可以喷射到基底上并用紫外线辐射固化。 墨水的喷射和固化可以由附着有打印头的紫外灯的喷墨打印头引起。 这种灯头可用于喷墨打印机。 本发明的其它方面包括多色油墨组。

    • A dye-based fingerprint ink composition includes a fatty-acid based dye dispersed in a chemical composition which includes approximately equal parts of (a) 2 phenoxyethanol, (b) propylene glycol, (c) a carrier and (d) glyceryl monoricinoleate. The composition further includes a viscosity adjustment chemical selected from the polyvinyl family of chemicals, the viscosity adjustment chemical operative to add accuracy to said dye-based fingerprint ink formulation and provide improved ridgeline definition. The fatty-acid based dye comprises less than approximately two percent (2%), by weight, of the fingerprint ink composition yet still provides acceptable quality and contrast levels.
    • 染料指纹油墨组合物包括分散在化学组成中的脂肪酸基染料,其包含大致相等的(a)2苯氧基乙醇,(b)丙二醇,(c)载体和(d)单蓖麻油酸甘油酯。 组合物还包括选自化学品的聚乙烯醇系的粘度调节化学品,该粘度调节化学品可操作以增加所述基于染料的指纹油墨配方的精确度并提供改进的脊线定义。 基于脂肪酸的染料的指纹油墨组合物的重量小于约2%(2%),但仍提供可接受的质量和对比度水平。
