ABSTRACT:
A method and apparatus for varying the flow of ink by differential adjustment at individual adjustment locations along the length of an ink metering device of a printing machine inking mechanism by a plurality of adjusting devices such as control motors, stepping mechanisms or the like, which are adjustable to differing extents by electronic control devices in accordance with variations in reference value presettings which are the same for all individually adjustable adjustment locations, using reference value-real value comparators which cause actuation of the adjusting devices, in which a reference value memory is provided for each adjusting device, and upon input of reference value variations the values of all reference value memories are multiplied by a selected predetermined reference value variation factor and the products of the multiplication are transmitted as new reference values to the reference value-real value comparator.
