Abstract (en)
[origin: US2002073865A1] A method for regulating the ink-to-wetting agent equilibrium in a rotary offset printing machine, the wetting agent quantity being determined especially using the signals of a sensor which measures the light reflectance of an area on the printing form of the rotary printing machine that is wetted by a wetting agent. The method includes: presetting the wetting agent quantity supplied to the printing form, calibrating the wetting agent quantity supplied at an ink quantity that is essentially kept constant, adjusting the wetting agent quantity to a wetting agent quantity setpoint value that is characteristic for the specific print job, increasing or decreasing the ink quantity from an ink quantity setpoint value to an ink quantity target value that is desirable for the printing job to be processed, and a corresponding increasing or decreasing of the wetting agent quantity setpoint value in the same direction to a wetting agent quantity target value, and regulating the supplied wetting agent quantity in a closed control loop as a function of the wetting agent quantity target value.
