    摘要: A pigment dispersion process includes providing a solution in a dispersion apparatus tha includes a container, a rotor-stator type homogenizer and a recirculation device. The process includes adding pigment particles to the solution to form a dispersion, flowing at least a portion of the dispersion to the homogenizer via the recirculation device, reducing a size of the pigment particles using the homogenizer, and recirculating the dispersion between the container and the homogenizer via the recirculation device. The dispersion system may include a container containing a dispersion that may contain an amount of deionized water, an amount of surfactant and an amount of pigment, and a recirculation device coupled to the container and to a rotor-stator homogenizer that allows the dispersion to flow between the container and the homogenizer.
