Patent number: 8796358Abstract: An ink for high-speed printing is formulated by controlling the phase angle of the ink to less than 60° at a frequency of 10 Hz 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 to 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. The ink is applied to a substrate, which moves at a speed of greater than 1200 feet/min.Type: GrantFiled: March 1, 2011Date of Patent: August 5, 2014Assignee: Sun Chemical CorporationInventors: Richard R.
