    摘要： A process for preparing a pigment dispersion including melting a phase change ink carrier and an optional dispersant at a temperature of from about 100° C. to about 170° C. in a jacketed vessel comprising a jacket surrounding an immersion mill or basket mill attachment and a dispersion blade attachment disposed within the jacketed vessel; mixing the melted phase change ink carrier and optional dispersant with a dispersion blade in the jacketed vessel; adding a pigment to the melted, mixed phase change ink carrier and optional dispersant in the jacketed vessel; wetting the pigment; after pigment wetting, reducing the pigment particle size using an immersion mill or basket mill attachment in the jacketed vessel; and discharging the pigment dispersion.

    摘要： A dry flushed pigment comprises a dry pigment and a flushing agent. Particles of the dry pigment are dispersed into the flushing agent. The dry flushed pigment may have at least 20 percent by weight dry pigment. The dry flushed pigment may have a range of 20 to 80 percent dry pigment by weight. A pigment concentrate comprising a dry flushed pigment and one or more of a group of an ink carrier, a dispersant, or a synergist, where the dry flushed pigment is mixed with one or more of the ink carrier, dispersant or synergist and then milled to create the pigment concentrate. The pigment in the pigment concentrate has a Z-average particle size in the range of 75 nm to 250 nm. The pigment in the pigment concentrates is present in the amount from about 15 to 60 percent by weight of the pigment concentrate.
