Abstract
Compositions, systems, and methods method of rapidly printing a black ink-jet image are provided. The composition can include a liquid vehicle including water, and from 15 wt % to 30 wt % organic solvent, wherein from 3 wt % to 10 wt % of the organic solvent is a methylated pentanetriol co-solvent; and from 1 wt % to 6 wt % of a dispersant-functionalized black carbon pigment. Obtaining firing frequencies from 15 kHz to 25 kHz are feasible with such compositions, provided the ink-jet architecture used with these pens is capable of firing at these very rapid rates.
