Device for controlling a printing temperature of an ink in a print head

A device for controlling a printing temperature of an ink in a print head of a system for inkjet printing, the device comprising:

• a heat exchanger comprising:
• a first channel for ink;
• and
• a second channel for a temperature control fluid;
• a chiller for heating and/or cooling the temperature control fluid;
• an ink circuit that is configured to pump ink through the heat exchanger and into the print head;
• and
• a temperature control fluid circuit that is configured to pump the temperature control fluid through the chiller and the heat exchanger,
• wherein the device is configured to heat and/or cool the temperature control fluid with the chiller such that a temperature of the ink is set within a predetermined temperature range and held therein;
• wherein at least one heating element is provided at the heat exchanger, which at least one heating element is configured to additionally heat the temperature control fluid and the ink with an electric current in order to more rapidly set the ink within the predetermined temperature range.
