Abstract: A method for feedback control of ink temperature in inkjet printing includes pumping ink through supply and return lines of an ink distributor and between these lines through print heads supplied in parallel with the ink, comparing a temperature actual value with a predefined temperature setpoint value and calculating a manipulated variable for a setpoint value of an ink heater from a setpoint/actual value deviation. A flow sensor is operated between the supply and return lines in parallel with the print heads and measures the flow of the ink or generates a measurement signal dependent on the flow. The flow or the measurement signal is converted by a predefined characteristic curve into a temperature auxiliary value used as the temperature actual value or temperature setpoint value for feedback control. This enables continuous unimpaired production by inkjet printing, particularly upon changes in viscosity of the ink in industrial inkjet printing.
