Abstract
A process for controlling the quantity of ink applied to a material being printed includes the stages of: driving an inking roller and a printing roller at first inking and printing speeds, changing the printing speed to a second printing speed, changing the inking speed to a second inking speed on the basis of a speed correction index, measuring a first and a second quantity of ink, calculating the difference in the quantities of ink applied, and altering the speed correction parameter on the basis of the difference in the quantity of ink printed. The process may be applied to offset presses.
