  • Flexographic coating and/or printing method and apparatus including interstation driers
    Patent number: 4939992
    Abstract: A straight line flexographic printing method and machine having a plurality of in-line liquid application stations, at least one of which is an upstream ink image-printing stations for printing ink images on a succession of cardboard copy sheets, and at least one of which is a final downstream liquid-application station which may be a coating application station for printing a protective, and/or aesthetic coating over selected portions of, or over the entire ink image-printed surface of each cardboard copy sheet. The present method and apparatus involves the placement of a forced hot air drying station between each of the liquid application stations to evaporate volatile solvent/diluent from the ink images applied at each inking or coating station before the application of additional ink images or coatings thereover at the next downstream liquid application station.

  • Coating and printing apparatus including an interstation dryer
    Patent number: 4841903
    Abstract: An offset lithographic printing method and machine having a plurality of in-line liquid application stations, at least one of which is an ink image-printing station for printing lithographic ink images on a suitable receptive copy sheet, and at least the final downstream liquid-application station is a coating application station for printing a protective, and/or aesthetic coating over selected portions of, or over the entire ink image-printed surface of the copy sheet. The present method and apparatus involves the placement of a drying station between liquid application stations to evaporate volatile solvent or vehicle from the ink images and/or to solidify the liquid coating applied at upstream stations before the application of a continuous or spot coating thereover at the next downstream coating station.
