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.
