They are made in ball mills. Miscellaneous inorganic pigments used in ink are mainly the luminescent and pearlescent (nacreous) types. Luminescent pigments may either be the fluorescent type or the phosphorescent type. The processes of fluorescence and phosphorescence differ in the time delays involved between the absorption and emission of light.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
