A method for monitoring printed material which is produced by a printing press and includes images printed on a paper web. The method includes the steps of determining, in an original, reference values for chosen parameters of the printed material, detecting the values of these parameters in the corresponding printed image, comparing the detected values to the reference values, and performing a correction when a difference in these values is found during the comparison. The chosen parameters may include the colours in the printed material, the location of the images in the printed material and/or the colour register of the printed material. A system for performing this method includes a reference value determining device, a detecting device and a comparing and correcting device connected to the reference value determining device and the detecting device.
