    Abstract: A composite color includes a first colored ink and a second colored ink. The first colored ink exhibits a color that is different from that exhibited by the second colored ink. The first colored ink includes pigment particles either formulated at a basic pH so that a surface of the pigment particles carries a net negative charge or formulated at an acidic pH so that a surface of the pigment particles carries a net positive charge; and the second colored ink includes pigment particles either formulated at an acidic pH so that a surface of each of the pigment particles carries a net positive charge or formulated at a basic pH so that a surface of the pigment particles carries a net negative charge. The first colored ink and the second colored ink have opposite charges. The composite color exhibits enhanced color richness when printed on a substrate.

    Abstract: A printing system has a substrate, and first and second colored inks. The first colored ink has particles of a first pigment, and the particles have a first net zeta potential. The second colored ink has particles of a second pigment and a polarity-reversing amount of a surfactant. The particles of the second pigment have a second net zeta potential opposite in polarity to the first net zeta potential. The first and second colored inks are configured to be printed together over a common surface of said substrate to form a composite color.

    Abstract: A method for tagging an ink with an isotopic tagging composition is provided. The method includes tagging the ink with a tagging composition having an artificial abundance of at least one isotope of an element to produce an authentic ink having an artificial abundance of the at least one isotope of the element which exceeds a natural abundance thereof in the authentic ink. A method for authenticating unidentified ink samples by comparing isotope abundances and/or abundance ratios in the unidentified ink samples with isotope abundances and/or abundance ratios in authentic inks tagged with isotopic tagging compositions is also provided. The method also includes tagging a pigment-based ink with trityl-protected thiol additives and methods for identifying inks containing the same.
