Abstract

The present invention relates to a method for visualization of non-visible information on a packaging material to provide traceability. The method comprises the steps of: reading the non-visible information from the packaging material by means of a magnetic head reader, processing the non-visible information in a central processing unit together with additional new non-visible information, and printing an optional portion of the amount of combined non-visible information onto the packaging material as a traceability marking. The invention also relates to a device for carrying out the method and a packaging line with a filling machine making use of the device.
