Abstract: A method is provided for detecting value labels that have been re-used, that have a surface containing a luminescent substance, and that have been applied to mailpieces that are to be transported. These mailpieces pass through a sorting system in which the presence of value labels that have a surface containing luminescent particles which are distributed essentially evenly is checked. The mailpiece having such a surface is conveyed to a marking device. Here, the substrate in the form of the surface of the value label containing luminescent particles which are distributed essentially evenly is irradiated with high-energy radiation. In this process, wherever the radiation strikes the substrate, the luminescence of the particles is destroyed to such an extent that they are no longer detected as being luminescent when they pass through the sorting system once again.

Abstract: The invention relates to a method for the automatic verification of the authenticity of a postage indicium that has a value indication and that has a luminescent area, whereby the postage indicium has been applied onto the surface of a mailpiece, and whereby the surface of the mailpiece is illuminated with light having wavelengths from a spectral region, then a first image of the surface of the mailpiece is taken with a camera system and this first image is evaluated regarding the place of the postage indicia applied onto the surface of the mailpiece, subsequently the postage indicium is irradiated with light having wavelengths from a second spectral region, whereby this light is capable of exciting the luminescence of the luminescent printing ink.

Abstract: A method for printing mail wherein the mail is fed to a printing device by means of conveyor and is printed in the printing device. The mail is fed by a first conveyor associated with a rotating device used to rotate and/or turn the mail; graphic characteristics of at least one surface of the mail are detected during conveyance of the mail; the graphic characteristics thus detected are evaluated, information being obtained from the result of the evaluation of the graphic characteristics determining which surface of the mail is to be printed; the rotating device rotates and/or turns the mail in such a way that the surface of the mail to be printed is oriented in a desired manner and fed to a printer disposed in the printing device.

Abstract: The invention is concerned with a method for identifying different, elongated metallic objects according to position and/or shape and/or type. In this method, by means of a conveyor, an object lying singly in a predetermined or a random position on conveyor is guided in terms of its conveyor direction evenly and at a constant speed over at least one inductive scanner, the induction voltage which varies temporally while object is passed over inductive scanner, is measured.
