Thermal ink-jet inks are provided containing a colorant and a vehicle, the vehicle comprising from about 8 to about 20 wt % of a 1,2-diol, from about 0.1 to about 5 wt % of at least one non-ionic surfactant, and optionally 0 to about 5 wt. % of a aliphatic alcohol; 0 to about 1.5 wt % of at least on

Thermal ink-jet inks are provided containing a colorant and a vehicle, the vehicle comprising from about 8 to about 20 wt % of a 1,2-diol, from about 0.1 to about 5 wt % of at least one non-ionic surfactant, and optionally 0 to about 5 wt. % of a aliphatic alcohol; 0 to about 1.5 wt % of at least one component independently selected from the group consisting of buffers, biocides, and metal chelators; and the balance water. The inks formulated according to the present invention provide the desired dot gain and dot symmetry on the print medium, in particular, gelatin coated media, while providing excellent color-to-color bleed alleviation. The images generated with the inks of the present invention exhibit excellent, near photographic image quality.
