An ink jet ink composition comprises a liquid vehicle, a single dye component, a surfactant and a glycol. The dye is water soluble and selected from the group consisting of Direct Dyes, Acid Dyes and Food Dyes, and preferably from the group consisting of Direct Yellow 86, Acid Red 249, Acid Red 92 and Direct Blue 199. Concentration of the dye is preferably in the range of 1% to 2% by weight. Using the ink composition of the present invention, images are generated by a continuous stream digital color press ink jet printing apparatus. In a preferred embodiment, to optimize runnability and jet straightness, the digital color press employs a gold orifice plate having an orifice diameter in the range of 0.7 to 0.8 mil.
