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. |
