Contact Pressure Tester CONPRESS II

The Contact Pressure Tester CONPRESS II has successfully proven itself to be irreplaceable during printing press assembly and service, e. g. for offset presses. It allows the control of the contact pressure between the bearer rings of printing presses by comparing the calculated actual value to a predetermined setpoint value, thus easing the adjustment. A very thin, fine paper measurement strip is pressed between the activated bearer rings. The resulting line or roll impact is analysed optoelectronically. For roll impacts, the device is able to provide information about the pressure distribution along the width of the bearer ring contact zone. Based on the analysis, the printing press settings can be optimised, ensuring consistent print quality and prolonging the lifetime of the cylinder bearers.
