At a paper mill (when forming roll) industrial ink jet printer, for example, through each meter is printing control marks 3 field marking (i.e. resepectively subsequently printed on the factory area, usually located at the edge of the paper web 1) in the form of digital codes (for example, a nine-digit number with increment). To indicate the direction of increasing numbering code information, for example, before each reference mark 3 is printed arrow. After the printer is installed, the system of control and accounting applied labels 3 and distances (step 4) between them. As between the control labels 3 distance is small, then resizing the canvas from humidity, temperature and tension of the winding can be neglected and keep records of the length of the paper web 1 with great precision.

After winding roll 1 with the control labels 3 paper mill system in electronic and printed form forms a "passport roll"which shows the number of check marks 3 and the distance (step 4) IU who do them.
