A method for producing a data carrier includes a luminescent security element having at least two subregions, which at least do not completely overlap one another.

Method for producing a data carrier having a luminescent security element, and data carrier

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.

Method and device for testing a substrate with a luminescent substance

A value document with a carrier element and a foil element arranged in a partial region of the carrier element. 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 reflection layer is configured to reflect infrared radiation and the selection layer is configured to spectrally selectively inhibit transmission of infrared radiation. The inhibition of the transmission of the first wavelength and the inhibition of the transmission of the second wavelength differ by at least 10%.

Valuable document having a substrate element and a foil element, and method for classifying a valuable document

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.

Method and device for examining value documents

An intaglio printing ink includes capsule luminescent pigments and a further machine-readable feature substance. The capsule luminescent pigments include at least one core with a luminescent substance and one shell encapsulating the at least one core. They are characterized by their high luminescence intensity and high chemical stability, which enables a simultaneous loading of the intaglio printing ink with a further machine-readable feature. A printing method and a printed product include the intaglio printing ink.

Intaglio printing ink, printing process and printed article

A pigment system of different capsule-luminescent pigments have different emission spectra, preferably different color impressions of the luminescence emission, and possess substantially the same chemical stabilities. The capsule-luminescent pigments are based on organic or metalorganic luminescent substances.

Pigment system, luminescent dye system, and value document

The invention relates to an apparatus and a method for checking value documents marked with feature substances, and to the corresponding feature substances. The feature substances are detected on the basis of Raman or SERS spectroscopy also at high transport speeds with a spatial resolution in the low millimeter region or better and reliably identified.

Device and method for verifying feature substances

A method for checking the authenticity and/or the nominal value of a value document having luminescent feature substances, comprises: a1) the step of carrying out a location-specific measurement of first luminescence intensities (L1) at a first emission wavelength at different locations of the value document that have the location coordinates (O), to thereby obtain (O/L1) measurement value pairs; b1) the step of statistically analyzing the first luminescence intensities (L1) measured in dependence on the individual location coordinates (O), by determining at least one statistical parameter using a statistical method; and c1) the step of comparing the statistical parameter determined in the step b1) with one or more threshold values.

Method for checking a value document, value document, use thereof, and value document system

An apparatus, a corresponding method, and value-document processing system for checking value documents that has at least two radiation sources for giving off electromagnetic radiation with which a value document is irradiated, at least one sensor for capturing the electromagnetic radiation emanating from the value document, and generating corresponding sensor signals. The apparatus has an evaluation device configured to derive from the sensor signals corrected sensor signals taking into account at least one spectral property of the electromagnetic radiation of the at least two radiation sources. The sensor signals corrected in this way reproduce the actual reflection or transmission behavior of the value document substantially more precisely than the uncorrected sensor signals. Disturbing remission or transmission artifacts may be attributed to so-called auxiliary emissions of the radiation sources are eliminated or at least reduced.

Apparatus and method for checking value documents, particularly bank notes, and value document handling system

A security element has at least two luminescent substances, in which the security element has a first and a second luminescent substance which have a substantially identical, joint emission band. The first or the second luminescent substance, or both luminescent substances, have at least one excitation band that leads to an emission at the joint emission band only in the case of the first or the second luminescent substance.

Authenticity feature in the form of luminescent substances

The invention relates to a security element having at least two luminescent substances. The invention starts out from a security element having at least two luminescent substances, whereby the security element has a first and a second luminescent substance which have a substantially identical, joint emission band, whereby at least the first or the second luminescent substance, or both luminescent substances, have at least one excitation band that leads to an emission at the joint emission band only in the case of the first or the second luminescent substance.

A method for checking, in particular the authenticity and/or the nominal value of a value document having luminescent feature substances, comprises: a1) the step of carrying out a location-specific measurement of first luminescence intensities at a first emission wavelength at different locations of the value document that have the location coordinates, to thereby obtain measurement value pairs; b1) the step of statistically analyzing the first luminescence intensities measured in dependence on the individual location coordinates, by determining at least one statistical parameter using a statistical method; and c1) the step of comparing the statistical parameter determined in the step b1) with one or more threshold values.

A security feature has a luminescent component and a component camouflaging the luminescent component. A security feature has a luminescent component with at least one luminophore consisting of a doped host lattice, and a component camouflaging the luminescent component, wherein for camouflaging the luminescent component, relevant properties required for identifying the luminescent component are camouflaged by the camouflaging component by the relevant properties of the luminescent component. The relevant properties being camouflaged by the camouflaging component in at least two of the relevant properties by the camouflaging component having relevant properties that correspond to the respective relevant properties of the luminescent component, thereby impeding or preventing a recognition of the luminescent component.
