    摘要: Liquid electrophotographic ink concentrates and methods of preparing the same are disclosed herein. An example of the method includes preparing a mixture of ink components using a first predetermined thermal profile. The ink components include a resin, a pigment, and a carrier. The method further includes preparing a microfluidizer with a composition at a temperature within a predetermined range and processing the mixture in the prepared microfluidizer to form the concentrate. Processing the mixture includes pressure-feeding the mixture into the prepared microfluidizer, passing the mixture through the prepared microfluidizer for a predetermined number of times, and utilizing a second predetermined thermal profile while passing the mixture through the prepared microfluidizer. A viscosity modifier is added to the mixture before and/or during the processing of the mixture.

    摘要: A system and method of ink-jet printing on vinyl print media can comprise jetting an ink-jet ink onto a vinyl print medium to form a printed image, and applying from 50-100° C. of heat to the printed image. The ink-jet ink can include a colorant, an aqueous liquid vehicle, and core-shell polymer particles. Upon printing and heating, at least a portion of the aqueous liquid vehicle evaporates, the vinyl print medium plasticizes (but does not flow), and the ink-jet ink flows. The fused polymer particles form a film that encapsulates at least a portion of the colorant.
