Definitions

  • the invention relates to a method for processing an object, in which the object is printed with a printed image using a digital printing system and then further processed in at least one work station, the at least one work station being controlled by an electrical controller.
  • the invention also relates to a device for carrying out such a method.
  • a decoration is understood to mean in particular a graphic, particularly preferably a pictorial representation, with which the optical impression that the printed paper web creates is intended to be changed.
  • the paper web is in the form of a roll and is unrolled or unwound from the roll for printing. Preferably, after printing, it is trimmed to the correct size depending on the application. This can, but does not have to, take place directly after printing. It is also possible, after the paper web has been printed, to roll it up onto another roll and feed it to the next work step.
  • Using a digital printing system to print the surface of the object has a number of advantages. For example, you can switch from one decor to another very quickly and easily. No rollers or similar elements have to be removed or exchanged for this, so the changeover times are very short.
  • Printed objects for example paper webs, are further processed in at least one subsequent work station, depending on the application.
  • the work station is preferably a device or system that is controlled by means of an electrical controller, in particular a control program running in an electronic data processing device.

  • the method according to the invention makes it possible to change the input parameters of the object, the printed image applied and/or the intended use of the product or intermediate product manufactured with the object, and only to change the printed image and/or the applied control characters.
