Method for printing a paper, and digital printing device

Abstract

The disclosure relates to a method for printing a paper by a digital printing system which has a plurality of ink application units for applying printing ink of different colours to the paper. The paper to be printed is guided past the ink application units in a feed direction. The digital printing system has a device which is designed and suitable for preventing or reducing the formation of condensation on the ink application units, and this device is used to prevent or reduce the formation of condensation on the ink application units. The device has a temperature-control device and an electrical controller, wherein the temperature-control device is designed to influence a temperature of the ink application units, and the electrical controller is designed to control the temperature-control device in such a way that the ink application units have different temperatures. The temperatures of the ink application units increase in the feed direction and temperatures of two adjacent ink application units differ by at least 0.5° C. and by at most 1.5° C. The temperatures of the first ink application unit in the feed direction and of the last ink application unit in the feed direction differ by at most 10° C.
