Pigment dispersion can be divided into three overlapping steps: Wetting—for good wetting, the dispersant must have a lower surface tension than that of the pigment. This enables the dispersant to displace air and water from pigment surfaces and penetrate pores, gaps, and channels between particles and adsorb onto them.

Pigment grinding or milling entails the incorporation of the pigment into the paint and ink vehicle to yield a fine particle dispersion. The three stages of this process are wetting, grinding, and dispersion, which may overlap in any grinding operation. The wetting agent, normally a surfactant, wets the pigment particles by displacing air ...
Ball milling is a grinding technique that uses media to effectively break down pigment agglomerates and aggregates to their primary particles. Using a rotor or disc impeller to create collisions of the grinding media, the impact and force created by the bead mills collisions break down the pigment agglomerates.
