  • Patent number: 8796358
    Abstract: 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.

  • Publication number: 20060012810
    Abstract: The present invention provides a plurality of representations of color that are stored in an electronic color library and that can be selected by a user. After a color selection is made, a plurality of color ink formulas and/or colorant formulas capable of producing the selected color are provided. Further, other selections can be made to define a substrate or other criteria that can impact the color ink formulas. A plurality of color ink and/or colorant formulas are provided and optimized in order to reduce or eliminate undesired effects caused by metamerism.
