The carrier element has, at least in the partial region, a luminescence marker which is adapted to give off luminescence radiation which has at least a first wavelength and a second wavelength in each case in the infrared spectral region. The foil element has a reflection layer and a spectral selection layer. The selection layer is arranged between the carrier element and the reflection layer.

The inhibition of the transmission of the first wavelength and the inhibition of the transmission of the second wavelength differ by at least 10%.

Abstract: A method is provided for checking a substrate with a specified luminescent substance incorporated and/or applied areally. A substrate luminescent characteristic value for the substrate is ascertained, for which purpose a number N of luminescence intensity values are captured at respectively different locations on the value document, and the substrate luminescence characteristic value is ascertained in dependence on a rank order of the luminescence intensity values. It can be checked whether the substrate luminescence characteristic value meets a specified criterion.

Abstract: A method for checking value documents involves the steps of: irradiating, by an excitation device, a first side of the value document with excitation radiation for exciting luminescence of a luminescent substance on the value document, such that the first side is a back side of the value document, capturing luminescence radiation which was excited by excitation of the luminescent substance at a front side of the value document by at least a part of the excitation radiation after transmission through the substrate of the value document and exits the value document at least partly at the back side of the value document after transmission through the value document, by a capture device, and checking the value document in dependence on at least one property of the captured luminescence radiation by means of an evaluation device.

Abstract: A method for checking the coercive field strength of magnetic pigments of an areal sample which are contained in a magnetic region of the areal sample includes: after a magnetization of the areal sample until saturation, a first partial counter-magnetization of the magnetic pigments out by a magnetizing device, and a first measurement of a first magnetization value of the partially counter-magnetized magnetic pigments are carried out. The measured magnetization values are transmitted from the measuring device to a checking device. The checking device checks the magnetization values of the partially counter-magnetized magnetic pigments for ascertaining a check result that relates to the coercive field strength of the magnetic pigments and transmits the check result relating to the coercive field strength to an output device connected to the checking device.
