    • A method of formulating ink for high-speeding printing includes controlling a surface tension of the ink to equal to or greater than 26 mN/m, equal to or greater than 28 mN/m, or equal to or greater than 30 mN/m. The surface tension is measured when the ratio of the total non-volatiles volume fraction of the ink to the maximum total non-volatiles volume fraction of the ink is a ratio between about 0.40 and about 0.90. An ink for high-speed printing includes one or more resins, one or more colorants, one or more solvents, and one or more additives. The ink can be a flexographic ink, a rotogravure ink, a heatset offset ink, or a publication gravure ink. A print of the ink includes less than 1 % of pinholes by area. A method of printing includes preparing an ink and applying the ink to a substrate. The ink has a surface tension of equal to or greater than 26 mN/m, and the substrate moves at a speed of greater than 1200 feet / min.
    • 配制用于高速印刷的油墨的方法包括控制油墨的表面张力等于或大于26mN / m,等于或大于28mN / m,或等于或大于30mN / m。 当油墨的总非挥发物体积分数与油墨的最大总非挥发物体积分数的比率为约0.40和约0.90之间的比率时,测量表面张力。 用于高速印刷的油墨包括一种或多种树脂,一种或多种着色剂,一种或多种溶剂和一种或多种添加剂。 油墨可以是柔性油墨,凹版印刷油墨,热固胶印油墨或出版物凹版油墨。 油墨的印刷包括面积小于1%的针孔。 印刷方法包括制备油墨并将油墨施加到基材上。 油墨具有等于或大于26mN / m的表面张力,并且基板以大于1200英尺/分钟的速度移动。
