Abstract (en)
[origin: WO8901409A1] An apparatus for printing quasi-random numbers in a rotogravure press having a plurality of printing stations with different size printing cylinders (7, 11, 13, 17, 19, 23). A photoelectric cell (10) disposed adjacent each cylinder detects registration marks (14) thereon and provides a signal to motor controller (11) which outputs a speed control signal (12) to its associated cylinder to vary the speed of the cylinder depending on the timing of the registration marks (14).
