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.
