Embodiment Construction

[0030] figure 1A standard cigarette pack 10 of the flip-top cigarette type is shown as an object for imprinting. The printing and checking method according to the invention is explained by way of example using the standard cigarette pack.

[0031] This printing and inspection method is used during the production process of the corresponding product, here the cigarette pack 10 . Of course, the present invention is not limited to such cigarette pack 10 printing. It can generally be used in conjunction with every type of equipment used to manufacture and / or pack cigarettes. In this case, it is independent neither of the type of machine used nor of the types of cigarettes or cigarette packs that can be produced.

[0032] It is often necessary to print the corresponding printing carrier during the production process, ie at a suitable point on the production line or on the corresponding packaging machine, and to also check the printing "inline" for errors. For this purpose, such...

Abstract

The invention relates to a method for automatically applying imprints to print carriers (17) used in the production and / or packaging of cigarettes, in particular to cigarette packs (10) or blanks for cigarette packs, and for subsequently automatically checking the imprints (12a-12c) by optical means, in the case of which, during the production and / or packaging process, the respective imprint (12a-12c) is applied to the print carrier (17) by means of a printing unit (11), in particular a laser printer, and at least one checking image (15) containing the imprint (12a-12c) applied is taken using a checking means (13), in particular a camera. The invention is characterized in that a virtual reference image (16) containing the imprint (12a-12c) is generated on the basis of graphic data, in particular vector graphic data, describing the imprint (12a-12c) which is to be applied, and in that the virtual reference image (16) is compared with the checking image (15) taken by the checking means (13).

Description

technical field [0001] The invention relates to a method for the automatic application of imprints to printing carriers used in the manufacture and / or packaging of cigarettes, in particular to cigarette packs or cigarette pack blanks, and for the subsequent automatic optical processing of said imprints A method of inspection, wherein, during the production and / or packaging process, a corresponding imprint is applied to a print carrier by means of a printing unit, in particular a laser printer, and at least one image containing the applied Stamped inspection image. Furthermore, the invention relates to a printing and inspection device for carrying out the method. Background technique [0002] In packaging machines used in the cigarette industry, in particular inspection systems operating optoelectronically are used in order to check the markings on the cigarette packs "inline". Here, the camera of the inspection system detects the side of the package on which the imprint is...
