Zusammenfassung:The present invention is directed to aqueous ink jet ink compositions for use with commercial offset media and offset ink. The present invention is directed to aqueous based ink compositions for ink jet printing on offset media and offset ink comprising combinations of dye-based and pigment-based colorants, and optionally surfactants. Optionally solvents and binders can be also added. In another formulation, an effective amount of the combination of ink colorants, at least one surfactant, being present at from about 0.1% to 1.5% by weight and an effective amount of at least one binder (such as an acrylate binder) is disclosed.
