  • Patent number: 5048418
    Abstract: The flexographic printing machine with an impression cylinder mounted in a double-sided printing-machine frame and regulated to a constant operating temperature, and with several flexographic printing units, is characterized in that the printing-machine frame is temperature-stabilized at least in the projection range of the impression cylinder. It thereby becomes possible to guarantee a high printing quality, even without readjustment, after the operating temperature has been reached.
