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.
A method of varying the flow of ink in a printing machine inking mechanism by differential adjustment at individual adjustment locations spaced along the length of an ink fountain roller metering device, such as an ink blade or plural individual ink metering elements, by a plurality of adjusting devices, such as servo motors, stepping mechanisms or the like, each of which is adjustable selectively by a computer in accordance with variations in reference value presettings using reference value-real value comparison means to actuate the adjusting devices, including the following steps:
