Abstract (en)

[origin: EP1782953A2] The method involves measuring quantity of ink applied to a web paper when an inking roller (14) and a blanket roller (8) rotate at respective inking speed and printing speed. Another quantity of ink applied to the paper is measured when the inking and blanket rollers rotate at other inking speed and printing speed, respectively. A difference value which represents the difference between the quantities of ink is calculated, and a speed correction parameter is adapted based on the difference value. Independent claims are also included for the following: (1) a method for adjusting a thickness of ink from two printing units (2) a device for adjusting thickness of ink applied to a material printed by a printing unit.
