  • Method for cleaning an anilox printing unit
    Patent number: 9205642
    Abstract: A method for cleaning an anilox printing unit includes a first process step and a second process step immediately following the first process step without any intermediate printing operation. In the first process step, printing ink is supplied to a screen roller from a blade-type ink fountain while an ink applicator roller is in contact with the screen roller and out of contact with a bridge roller of a dampening unit. In the second process step, printing ink is removed from the screen roller and returned into the same blade-type ink fountain while the ink applicator roller is engaged with the screen roller and with the bridge roller.
