Abstract: 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.
