ABSTRACT:
An ink squeezing device for an anilox roll comprises a doctor blade adapted to contact the roll at an angle against the direction of rotation of the roll, and a bank member supporting the doctor blade along the anilox roll. An ink fountain is formed by the doctor blade, the anilox roll, the bank member and a pair of dam members. The ink squeezing device is coupled to a pressure cylinder device for pressing the doctor blade against the anilox roll. The cylinder device presses the doctor blade against the anilox roll during printing and during cleaning of the anilox roll. The doctor blade also serves the function of scraping off a cleaning liquid from anilox roll during cleaning of the roll.
