Abstract
A method and apparatus for controlling the ink feed in a vibrator-type inking unit of a printing machine, especially a sheet-fed offset printing machine, the ink being fed via individual ink metering elements which interact with an ink fountain roller, and the ink metering elements and the vibrator cycle and/or the vibrator strip width being set to correspond to the overall proportion of the printing area of the printing plate and, in order to obtain pre-setting values for the ink feed, the proportion of the printing area in the individual ink metering zones being determined. The method and apparatus are intended to provide an improvement in the transient response of the inking for any desired subject. In the individual ink metering zones, the proportion of the printing area is compared with a predefined limiting value, and in the regions in which the proportion of the printing area is smaller than the predefined limiting value, ink is fed only in at least each second ink metering zone, and in those regions in which the proportion of the printing area is greater than the predefined limiting value, ink is fed in accordance with the proportion of the printing area in each metering zone.
