Abstract: A transparent white ink composition is formulated to brighten, lighten and or dilute full-tone primary inkjet colors: cyan; magenta; yellow and black, eliminating the need for ‘light ink’ primary color inks. The transparent white ink is jetted concurrently with reduced amounts of full-tone inks in lighter tonal areas conventionally supported by ‘light ink’ primary inks. Printing ‘light ink’ primary colors using a transparent white ink composition may reduce the number of print channels needed to print all four primary colors and the four ‘light ink’ primary colors. Embodiments of the transparent white ink composition may be solvent- or water-based, drying by evaporation of the carrier fluid. Other embodiments may be radiation-curable ink compositions. An inkjet printer includes print carriage and print head assemblies configured for jetting a primary color ink and the transparent white ink in the same pass in correct proportions to achieve a desired effect.

Abstract translation: 配制透明的白色油墨组合物以增亮，减轻和/或稀释全色原始喷墨颜色：青色; 品红; 黄色和黑色，无需“轻油墨”原色油墨。 透明白色墨水与通常由“浅色墨水”初级墨水支撑的浅色调区域中的全色墨水同时喷射。 使用透明的白色油墨组合物印刷“浅色油墨”原色可以减少打印所有四种原色和四种“浅色油墨”原色所需的打印通道数量。 透明白色墨水组合物的实施方案可以是溶剂型或水性的，通过载体流体的蒸发进行干燥。 其它实施方案可以是可辐射固化的油墨组合物。 喷墨打印机包括打印托架和打印头组件，其被配置为以相同的顺序以正确的比例喷射原色墨水和透明白色墨水以实现期望的效果。
