摘要： 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.

摘要： A method of manufacturing a liquid electrophotographic ink includes: mixing a first portion of a carrier fluid and a resin to form a resin mixture; heating the resin mixture until the resin has melted; cooling the resin mixture to form a resin cake, followed by pulverizing the resin cake to form a resin powder; and mix the resin powder with a pigment and a second portion of carrier fluid in a microfluidizer to form a concentrating ink containing composite particles. An alternate method of manufacturing a liquid electrophotographic ink includes: mixing a pigment with a resin powder; and microfluidizing the mixture together with a carrier fluid in a microfluidizer in a number of passes to form a concentrated ink containing composite particles.
