ABSTRACT Disclosed is a process and device for detecting print register marks on a multi-colour printing press. The process consists in detecting a printed register mark composed of recognition signs and of colour pilot marks, in comparing the image of the signs of the print register mark to the signs of a virtual reference register mask and then in defining a basic area for each sign, in calculating the geometric centers of every basic area, in detecting in these basic areas a colour print pilot mark, in calculating and memorizing their geometrical center, in measuring the off-line positions (.DELTA.x to .DELTA.x2 and .DELTA.y to .DELTA.y2) between the geometrical centers of the basic areas and the geometrical centers of the colour print pilot marks, and in ultimately utilizing these results for controlling the misregister correction device of a printing press. The process is applicable in the field of colour register control on multi-colour printing presses.
