Abstract: An ink-jet ink printing method and associated system can have a printer including an ink-jet ink. The ink includes an aqueous liquid vehicle, 1 wt % to 5 wt % pigment, 1 wt % to 5 wt % acrylic polymer particles, 0.3 wt % to 3 wt % urethane polymer particles, and is formulated to print on a vinyl medium. The system also includes a heating device. Upon applying heat to the ink-jet ink printed on the vinyl medium, the polymer particles in the printed ink fuse, and form a film encapsulating at least a portion of the pigment on the vinyl print medium.
