Abstract
The present invention is drawn to photo-curable ink-jet ink compositions, systems, and methods. One exemplary ink-jet ink composition includes a liquid vehicle, a milled pigment which has been milled in a milling solvent having minimal to no gas solvency for the milled pigment, and a photo initiator. In this embodiment, the composition can be ink-jettable at frequencies of at least 29 KHz without requiring degassing during printing.
