  • Patent number: 5690028
    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.

  • Patent number: 5495800
    Abstract: The present invention is directed to an anilox roll printing ink hand proofing device which includes a base frame having an elongated member adapted to receive a handle and sideframes; a handle connected to the base frame, sideframes on the base frame, a nesting subframe for an anilox roll, an anilox roll, a doctor blade on the nesting subframe, blade adjustment capabilities, and a transfer roll. The handle includes a hollow elongated member and contains a pressure rod in the hollow elongated member. There is also a pressure rod adjustment mechanism connected to the pressure rod and to the handle so as to indirectly change the pressure on the anilox roll against a transfer roll. Finally, there is a pressure rod release mechanism attached to one of the rod, the pressure rod adjustment mechanism and the handle so as to act as a quick release to release the pressure between the anilox roll and the transfer roll without affecting the pressure rod adjustment mechanism setting.
