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.
