    摘要： Techniques to determine concentration parameters of conductive liquid electrophoretic (LEP) inks are illustrated herein. In an example, a layer of conductive LEP ink is formed on a developer roller using electrostatic forces acting on the conductive LEP ink. A current is generated in response to a voltage between a measurement electrode and a developer roller. The current flows through the conductive LEP ink layer.

    摘要： An ink composition includes a particulate pigment, a hydrocarbon vehicle, an organic polyamine and an organic polyacid. A ratio by weight percent of the organic polyamine to the organic polyacid in the hydrocarbon vehicle is sufficient to render a conductivity of the ink composition to equal to or less than 15 nanosiemens per centimeter. The ink composition is prepared by combining the particulate pigment with a composition that includes the hydrocarbon vehicle, the organic polyamine and the organic polyacid. The combination is subjected to conditions under which the particulate pigment becomes dispersed in the composition.

    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.
