EVERY printing ink is formulated from three basic components:a colorant,a vehicle system to carry the colorant,and additives such as waxes and driers.Colorants may be dyes,but more often are pigment-based.They may be in powder form(dry toner),in a concentrated paste dispersion known as a flush,or in a liquid dispersion.Vehicles are made up of oils(petroleum or vegetable),solvents,water,or a combination of these.Most vehicles also contain resins,which serve to bind the colorant to the printing surface.Additives can include waxes,driers and other materials that add specific characteristics to an ink or to the dried ink film.
