ABSTRACT:
Compositions and methods for ink-jet printing having increased slewing decap time and reduced clogging are disclosed and described. An ink-jet ink composition can include a colorant and a liquid vehicle having a surfactant. The surfactant can have a critical micelle concentration with respect to the ink-jet ink composition. In addition, the surfactant can be present in the ink-jet ink composition at a concentration from about 0.4 to about 0.95 times the critical micelle concentration. Further, the surfactant can also have an aromatic-containing portion. Using the ink-jet inks of the present invention during printing can allow for reduced clogging and increased stewing decap time during ink-jet printing on a variety of substrates with improved reliability, faster printing, and more efficient use of the ink.
