An ink jet ink composition comprised an anti-curl agent and ink jet printing processing using such ink jet ink composition. The ink jet ink composition includes a hyperbranched polymer. The hyperbranched polymer acts as an anti-curl agent to control curl during a printing process. The anti-curl agent, i.e., the hyperbranched polymer, may be present in the ink amounts less than conventional anti-curl agents and still effectively control curl without detrimentally effecting intercolor bleed control water fastness or drying. Additionally, the ink composition do not exhibit increases in viscosity, and problems associated therewith, that occur in ink composition using conventional anti-curl agents.

Ink jet composition

An ink set for reducing intercolor bleed and a multi-colored ink jet printing process utilizing the same is provided. The ink set comprises a black ink composition and a plurality of color ink jet ink compositions comprising a colorant and an ink vehicle. The ink vehicle of at least one of the color inks matches the ink vehicle of the black ink. An ink set may also be a hybrid ink set comprising a black/color ink subset that includes a black ink composition and at least one color ink composition, and a color/color ink subset that includes a plurality of color ink compositions, wherein the ink vehicle of the color ink composition(s) in the black/color ink subset matches the ink vehicle of the black ink composition and the ink vehicles of at least one of the color inks in the color/color subsets match the ink vehicle of another color ink in the color/color ink subset.
