Abstract
The invention relates to an inkjet printing system () and method for controlling the jetting ink viscosity. A printing head () comprises a first pressure sensor () located at a fluid inlet () and a second pressure sensor () located at a fluid outlet (). A control unit () is configured to retrieve the volumetric flow (Q) from a supply pump () of the inkjet printing system () and the inlet and outlet pressures (P_in, P_out) from the pressure sensors (). The control unit () is further configured to calculate an actual flow resistance (R_a) and a required temperature change (ΔT) of the ink such that a calibrated ink viscosity (μ_ref) is obtained.
