Abstract: The present invention is directed to a method of printing ink upon a continuous substrate using a printing apparatus. First, the substrate is fed around a central impression cylinder which rotates so that the substrate successively passes through at least one face roll and a plurality of inking stations. When passing through each ink station, ink is heated to a predetermined temperature which is higher than the temperature of the central impression cylinder wherein the viscosity of the ink is dropped low enough so that the ink may be transferred to the substrate. Next, the ink at each inking station is applied to the substrate causing the temperature of the ink to drop and the viscosity to climb. This allows previous down inks to appear to be several times more viscous than the ink applied at the current inking station and to pull the ink off a printing plate in the direction of the substrate. Last, the inked substrate, which has passed through all inking stations, is cured at a curing station.
