Ink Three Roll Mill

Three roll mill is especially effective for pigment dispersion in high viscosity paste for heavy offset-litho base inks. It will be difficult to mill a liquid ink on a three roll mill, since the solvent tends to evaporate. Ball mills, instead, have been used to mill liquid inks. However, good dispersion through ball milling could only be obtained at proper viscosity (between 1600 to 2400 cps).
