  • Patent number: 8822562
    Abstract: Ink deposited on a substrate by an ink-jet arrangement to form a protective layer includes hardenable oligomer, hardenable monomer selected from a group including alkoxylated and/or poly-alkoxylated acrylic monomers comprising one or more di- or tri-acrylates, and a photoinitiator. The oligomer has a room temperature viscosity greater than 1 Pa·s. The oligomer to monomer weight ratio is between 1/6 and 1/25. The ink has a room temperature viscosity between 15 and 22 mPa·s and between 5 and 2 mPa·s at 60° C., and a room temperature surface tension between 15 and 28 mN/m. The photoinitiator is activated by a UV source having an appropriate wavelength and intensity.

  • Patent number: 8783806
    Abstract: A protective layer is applied to a substrate moving relative to an ink jet nozzle array. Each nozzle responds to a piezoelectric actuator. Shapes of ink droplets deposited by the nozzles on the substrate, to form the protective layer, are controlled by shapes of electric waveforms applied to the actuators. Shapes of the waveforms respond to at least one of: droplet viscosity and temperature, temperature of the substrate, desired thickness of the layer, type of substrate surface to which the droplets are applied, and relative to speed of the substrate and the ink jet nozzle array.
