14. The method of claim 1, wherein the at least one control character is printed simultaneously with the printed image.

15. The method of claim 1, wherein the at least one control character is imperceptible and becomes visible in ultraviolet light or infrared light.

16. The method of claim 1, wherein the impregnation station at least partially impregnates the printed web with a material after the printed image has been applied, the material being waterproof or at least water-resistant and the printed image is a decorative pattern which is protected by the material.

17. The method of claim 1, wherein the at least one control character contains information about its own position on the paper web.

18. A method for processing a paper web into a wood-based panel, in which a printed image is printed onto the paper web by a digital printing facility and the paper web is then further processed in at least one work station, the at least one work station being controlled by an electric control unit, wherein at least one control character is applied to the paper web by the digital printing facility, said control character being detected by at least one sensor and transmitted to the electric control unit, a first workstation being upstream of a second work station and the second work station being upstream of a third work station and each of the first work station, the second work station and the third work station being controlled by the electric control unit depending on the control character transmitted, the first work station, the second work station and the third work station configured to provide additional processing of the paper web including a combination of an impregnation station, a cutting station, a separation station or a packing station, wherein the cutting station cuts the paper web into a specified size that corresponds to a size of a carrier, prior to being applied to the carrier to form the wood-based panel, the at least one control character contains information on how large is the wood-based panel such that the electric control unit recognizes from the at least one control character how the cutting station has to be controlled and operated to generate layers of the paper web of a desired size.

Description

BRIEF DESCRIPTION OF DRAWINGS

(1) In the following, an embodiment example of the invention will be explained in more detail with the aid of the accompanying drawing. The FIGURE shows:

(2) FIG. 1 is a schematic sequence of a method according to an embodiment example of the present invention.

DETAILED DESCRIPTION

(3) From top to bottom, FIG. 1 schematically depicts the sequence of a method according to a first embodiment example of the present invention. Different control characters 4, which are schematically depicted by various geometric figures and objects, are printed onto three objects 2. This occurs in a digital printing facility, which is not depicted. The objects 2 printed in this way pass through a detection station 6 with at least one sensor 8, which is configured to detect at least the part of the objects 2 where the control characters 4 are printed. Preferably, however, the sensor 8 is configured to detect the entire printed surface of the object 2. The sensor 8 transmits the sensor data via a data line 10 to an electric control unit 12, which is depicted as an electronic data processing device. Even though the data line 10 is shown as a cable, it does not mean that this is a necessary embodiment. Of course, wireless communication between the sensor 8 and the electric control unit 12 is possible and, possibly, advantageous.

(4) The electric control unit 12 evaluates the sensor signals transmitted by the sensor 8 via the data line 10. This occurs, for example, via an image recognition software that is able to extract, identify and evaluate the control characters 4 from the rest of the printed image not shown in FIG. 1. The information contained therein is processed in a sorting station 14, which is only schematically depicted as an oval, and ensures that, in the example embodiment shown, the further production paths 16 of the objects 2 printed with different control characters 4 separate. They are fed to different processing stations 18, which are schematically labelled in FIG. 1 with the respective control character. This results in three different productions 20, which are also labelled by the respective control character, this time as an inverse depiction.
