Study on the Adjustment to the Pressure of Flexible Printing on the Board

Abstract:

During the flexo printing process of corrugated flexible resin version, precise pressure control is the key technical indicators of ink transfer, printing graphic reproduction as well as reducing the the loss of physical properties of corrugated board. The gaps △L between the printing roller and the impression cylinder were adjusted by the worm in this paper, different printing pressures are produced in the printing process, the impact of pressure change on flexo printing quality was described quantitatively. The results showed that: 7.5mm thick corrugated board used AB-type hardness of 36 Shore A, when a thickness of 3.94mm DuPont flexible resin was printed, the optimal pressure gap △L was 10.9mm, the flexible resin version of the real size was 3.73mm, and the thickness of corrugated board was 7.17mm, the board thickness was 7.30mm after decompression, the thickness of corrugated board after the printing was compressed by 2.7%. The result of this paper offers a certain theoretical reference and practical guidance to improve the quality of flexo and the production of high quality corrugated board.
