Dispersing refers to the process of breaking up the pigment molecules so that they can be evenly distributed in the final product.

A high‒speed disperser is highly efficient and in many cases all that is needed to achieve the required dispersion result. If however, a finer dispersion result is desired, dispersion becomes a two step process, with the disperser used for pre‒dispersion, followed by further milling in a bead or basket mill.
