摘要： The process and the device for measuring the displacement of a web within a multi-color rotary printing press by means of a mark simultaneously printed with each color in an area free of any printing characterized by the mark passing beneath the photodetector arrangements for generating a signal. The method and the device are further characterized by the fact that the pair of photodetectors are arranged side-by-side along a crosswise line with the edges of the field for each detector arrangement being positioned above the web at the expected position for the passage of the center of the crosswise symmetrical mark and the crosswise displacement of the web is determined by the difference between the intensity variations of the signals created by each of the two photodetectors when the mark passes therethrough.

摘要： A process consists of detecting a printed registration mark composed of recognition signals and of a color pilot mark, comparing the image of the signs of the printed registration mark to the signs of a virtual reference registration mark, then defining a basic area for each sign, calculating a geometric center of every basic area, detecting any color pilot mark in these basic areas, calculating and memorizing the geometric center for the detected pilot mark, measuring an offset position between the geometric center of the basic area and the geometric center of the detected color pilot mark and utiliziing the measured offset position for controlling a misregistration correction appliance of a printing press. The device for accomplishing the process includes an arrangement for performing each of the above-mentioned steps.

摘要： A process for correcting misregistration between imprinted images from successive printing stations comprising measuring the width of the imprinted image of each station and comparing the width to determine any difference, and creating a correction signal if a difference does exist to change the humidity in the web passing through the printing unit. The device includes photoelectric devices for determining the width of each image created at each station, an electronic device for comparing the width of each image and, if a difference exists, creating an error signal which is applied to the first drying unit and a secondary error signal applied to the second unit to correct the humidity of the web leaving each dryer.
