ABSTRACT:
In a control system for a plurality of ink zone adjusters in a printing machine each adjuster is connected via a main control circuit and a first bidirectional address and data bus to an input and output unit where the measured data are stored on specific addresses to be retrieved for later use. An additional storage control circuit is connected to the first bidirectional data bus to provide an intermediate storage of the measured or retrieved data. The addtional storage control circuit includes an addressing circuit controlled by a program control circuit to apply addresses pertaining to individual printing units to corresponding storing circuits. These corresponding storing circuits are connected through the first bidirectional data bus via a processing circuit including a switching device controlled by the program control circuit to connect the additional storing circuits either directly, or via an adder or via a coder, so as to compensate for play in the mechanical components of the adjusters or to separate coarse and fine adjustment in the ink zones.
A recording-reading storing device is provided in the input and output unit, which is connected to a double four-contact switch interconnected between the main control circuit and the circuits connected to the position sensors and the setting motors of the respective ink zone adjusters. All the adjustment steps can be simulated on the recording-reading storing device and the ink zones can be adjusted without interferring with the printing process.
