Abstract

A sensor for verifying value documents is designed to determine a luminescence characteristic of a value document that is moved past the sensor for verification purposes, and the provision of a velocity correction of the luminescence characteristic of the value document in the sensor, resulting in a distortion of the measured luminescence intensities. A reference sensor is used to determine an average velocity dependency of the luminescence characteristic of a reference medium, said average velocity dependency being averaged over both opposite directions of movement and being used to determine a velocity dependency of a corrective factor for the luminescence characteristic. Said determined velocity dependency is used to determine the corrective factor for the luminescence characteristic, said corrective factor applying to the velocity of the movement of the value document during the verification process, and the luminescence characteristic is then corrected by said corrective factor.

Abstract

A sensor for verifying value documents and designed to determine the luminescence time constant of a value document that is moved past the sensor for verification purposes, and the provision of a velocity correction of the luminescence time constant of the value document in the sensor. The relative movement between the value document and the sensor causes movement effects, resulting in a distortion of the intensity curve from which the luminescence time constant is derived. The luminescence time constant is corrected using a sensor-specific corrective factor ascertained for the velocity of the movement of the value document during the verification process. For this purpose, different sensor-specific corrective factors are used for different examples of sensors that are nominally identical in design and are part of the same sensor production series.

A window is arranged between the sensor module and the flat sample at a window distance from the target measurement plane, said window distance being selected to be sufficiently small for the measurement signal of the flat sample in the target measurement plane to be increased by a retroreflection effect of the window. The sensor module is arranged at a module distance from the target measurement plane, said module distance being selected to be sufficiently small for a signal variation of the measurement signal of the flat sample as a function of the measurement distance deviation in the region of the target measurement plane to be reduced by the retroreflection effect of the window compared to a signal variation occurring without the retroreflection effect.

Abstract

The invention relates to security element transfer materials (1) for transferring security elements (4) having a micro-optical authenticity feature to a valuable object (5, 30). The micro-optical authenticity features produce an optical effect by the cooperation of a first micro-optical arrangement (11), which has focusing elements (12, e.g. micro-lenses), with a second micro-optical arrangement (13), which has micro-motif elements (14). The security element transfer material (1) has a temporary carrier (3) in the form of a layered composite material. The temporary carrier is composed of a first temporary carrier substrate (31, 34) and a second temporary carrier substrate (32), which can be undetachably adhesively bonded by means of an adhesive layer (33). The outlines of the security elements to be transferred are cut in (8) or have been pre-cut (8), while the second temporary carrier substrate (32) is not cut, so that the temporary carrier can be removed as a complete carrier layered composite (figures 3i, 4g, 5h). A permant carrier (15) is undetachably joined to the micro-lenses. A transfer adhesive (18) makes possible the adhesion to the final substrate (30) of the valuable object.

The invention relates to a method for transferring a security element (3) onto a target substrate (1), comprising the steps of: - providing the security element (3); - applying the security element (3) to the target substrate (1); - irradiating a radiation-curable adhesive layer on the security element side to cure the radiation-curable adhesive layer which permanently bonds the security element (3) to the target substrate (1), wherein the security element is opaque to the irradiation in an effect region (32) and is transparent to the irradiation in at least one transparent element (31, 33, 34). For the irradiation on the security element side, a plurality of transparent elements (34; 31, 34; 33, 34; 31, 33, 34) are distributed in the security element (3) in such a way that, when irradiating through the transparent elements (34; 31, 34; 33, 34; 31, 33, 34), a plurality of cured partial surfaces (314, 334, 344) of the adhesive layer are formed which are separated from one another by at least one non-cured partial surface (324) of the adhesive layer. The plurality of transparent elements (34; 31, 34; 33, 34; 31, 33, 34) comprises a plurality of transparent grid elements (34).

Abstract

A method for classifying a banknote has at least one luminescent feature, in which the following steps are carried out: a) exciting the luminescent feature; b) recording at least a first intensity value of the excited luminescent feature at a first time and a second intensity value at a second time that is different from the first time; c) determining a decay time of the luminescent feature by approximate integration over the intensity values between the first time and the second time; d) comparing the determined decay time with a reference decay time of the luminescent feature; and e) classifying the banknote based on the comparison.

Abstract

An optical sensor for examining value documents, such that at a point in time before the check of the value documents, a self-test of the optical sensor is carried out, during which the light sources thereof are switched on, and, with the aid of monitor elements, the respective light intensity of the light source assigned to the respective monitor element is detected which impinges on the respective monitor element at the time of the self-test. During the check of a value document following the self-test, the light sources illuminate the value document, and measured values are recorded. The recorded measured values are then corrected with the aid of the light intensities detected by the monitor elements at the time of the self-test to take into account a change in the light intensity emitted by the light sources that occurs in the course of the service life of the light sources.

The fluorescent substance (28-F) and the phosphorescent substance (28-P) are each present as a luminescent substance in the core (24) of one or more of the capsule luminescent pigment varieties (22-F, 22-P) so that the capsule luminescent pigments form fluorescent capsule luminescent pigments (22-F) and/or phosphorescent capsule luminescent pigments (22-P). The luminescences of the fluorescent and the phosphorescent capsule luminescence pigments (22-F, 22-P) have the same light-fastness and the same chemical stability, and their luminescences visually produce a substantially matching colour impression.
