  • Patent number: 6779455
    Abstract: The gel method of printing variable information of the present invention involves applying inks onto a substrate that is part of or attached to a cylinder of the printing machine. Imaging is by means of an energy source in the UV, visible or infrared regions, modulated to represent a digital image pattern that has been composed on a computer. The consequence of imaging is to gel the ink and increase its adhesion to the substrate of the printing cylinder. The non-gelled background ink with lower adhesion is then removed by a squeegee action and returned to an ink reservoir. The remaining image is transferred to an offset blanket or directly to print stock by pressure. The process does not use a master, but produces an image that is erased after printing with each cylinder rotation so that the next rotation producing the next print can have fresh information written upon it.

  • Publication number: 20040050703
    Abstract: The quality of painted surfaces of polymeric articles is improved by depositing a coating of a metal such as zinc or zinc alloy on the surface of the article to be painted. For example, zinc is electrodeposited on a conductive surface of the article. The metal coated polymeric surface provides a good base for electrostatic deposition of either liquid or powder paint and the metal surface prevents the formation of defects in the painted surface during heating of the article to dry or cure the paint film.

  • Publication number: 20020056641
    Abstract: A cured multilayer coating provides an improved edge corrosion resistance to a substrate. The method of making the cured multilayer coating includes applying by electrophoretic deposition a first curable coating composition to the substrate to establish a coated substrate. The coated substrate is then subjected to an amount of energy sufficient to cause the coated substrate to become a conductive coated substrate. Next, a second curable coating composition is applied to the conductive coated substrate to establish a multicoated substrate. The multicoated substrate is then subjected to an amount of energy sufficient for cross-linking the first and second curable coating compositions to make the cured multilayer coating. The cured multilayer coating provides the substrate with an edge corrosion resistance improved by at least 100%, as measured according to an Edge Corrosion Test, while a surface roughness, Ra, of the cured multilayer coating is maintained at or below 13 &mgr;in (4.29 nm).
