Abstract
A method of making a phase change ink composition includes adding to a device with a stirring element at least one pigment, at least one dispersant and at least one synergist, processing the device at an elevated temperature and at a stirring rate to wet the at least one pigment to obtain an ink concentrate, and mixing the ink concentrate with an ink vehicle to obtain the ink composition. The device may be an extruder, an attritor or the like. The method allows for the reduction in the amount of dispersant to include in the ink.
