Research on the Methods of the Measurement of Printing Pressure in Offset Press
Pressure is one of the important parameters that decide the print quality in offset printing. A precise measurement method is needed at present. According to the working principle about the films with microencapsulated sensor, a new method for measuring the printing pressure was put forward in this paper. A detection experiment of impression force was carried out, which studies on the contact area between the impression cylinder and the blanker cylinder of an offset sheeted printing machine. At the same time, the experimental results were analyzed. The results show that the uniformity of the pressure distribution in the contact area mainly depends on the nature of the blanket, the substrate and other materials. In the contact area, along the direction of the cylinder axis, the pressure distribution is in accordance with the theory.
