Abstract
The present invention concerns a method and a device for absolute measurement of a print repeat length and/or at least one package length of a moving packaging web (1) in line with a printing machine. Normally the print repeat length and one package length are measured and analysed simultaneously. The measurements are made by means of a number of CCD-cameras (2, 3, 4) connected to a computer (6) by means of a frame grabber (7).
