Method and device for dynamically measuring the damping medium in printers

The invention relates to a method and a device for dynamically measuring the damping medium in ink and damping medium-conducting rollers. The object of the invention is to increase the accuracy of such measurements and thus to provide a further precondition for printed products with a higher quality. The objective of the invention is to provide a method and a device for dynamically measuring the prevailing damping medium states in ink and damping medium-conducting rollers. The objective is achieved in that the portion of emulsified and adsorbed damping medium is measured separately, the measured values being separately evaluated by the evaluation device arranged downstream of the measured value sensors and the measured values being converted into signals for a correction of the supply of the damping medium and ink. The device for measuring the adsorbed damping medium consists of measuring means for measuring the air humidity in the direct vicinity of the measuring area, for measuring the air humidity, the air temperature, the temperature of the roller and speed of rotation of the roller. The device for measuring the emulsified damping medium consists of a special capacitive measured value generator.
