  • the individual cracks 14, 16, 18 with light of different nature and wavelength or below
  • the uppermost layer 12 is screened at a first wavelength 22 (normal light), whereby the Krakeleerisse 16, 18 of this layer 12 are made visible.
  • the top layer 12 is designed so that only infrared rays of a wavelength 20 pass through.
  • this second wavelength 20 eg IR light at 900 nm or 1200 nm
  • the crackle cracks 14 of the underlying layer 10 can be made visible.
  • the scanning angle or angle of incidence can be used for the light. Depending on the angle you get a different picture of the crackle pattern.
  • the specification of the angle represents another security feature. It can also be recalculated via an algorithm individually for each test, the angle for the next test and more scans for
  • the angle can also be set manually.
  • the test result can also be compared with an existing 3D image of the crackle pattern. Simple mechanical treatment or treatment with ultrasound can initiate, accelerate or alter the formation of the spider in certain areas.
  • Fig. 2 shows a multi-layer security element.
  • individual cracks and cracks are visible as crackles.
  • the uppermost layer 4 you can also see places where there are signs of use, breakouts have occurred or which remained uncovered.
  • Abrasion processes can be seen in the underlying layer 3 Crackle cracks and vaults.
  • a matching characteristic from the database is first screened for the first test procedure (test 1).
  • the area to be tested is extended and further cracks are recorded (test 2).
  • the actual state of the surface is recorded and other features
  • test steps 1-3 can also be carried out individually or in a different order or in combination with other test steps.
  • One method of increasing safety and creating additional safety features is to use test equipment with different wavelength ranges during one of test steps 1-3 or by supplementing with further test steps
  • IR-A3 covers the range 1400 nm - 1700 nm and was not shown here.
  • Protective films such as protective lacquers, for example, can be scanned visibly with a first wavelength W1, that is to say with UV light, and show otherwise invisible changes or patterns to the eye.
  • Shrinkage can be scanned visibly with normal light (W2). These are characterized by wrinkles, which, for example, high binder levels
  • the crackle of the underlying layer can be visualized and analyzed with the wavelength W1 or W3 if it has been covered or filled, for example, by the protective lacquer and was invisible to W2.
  • the crackle crack shown reaches through to the lowest layer 1.
  • infrared (IR) scan methods are preferably used. For example, in the case of a survey with the wavelength W3, the crackle patterns of the uppermost layers 2 and 3 can be made visible, in particular. The crackle of the underlying layer 1 remains hidden.
  • IR infrared
  • Surveying at a wavelength W4 then also produces crackle patterns which are formed in the lowermost layer 1.

  • the crackle layer 12 is covered by another protective layer 13.
  • the protective layer 13 may also be used to consciously completely fill or cover individual cracks (see FIG. 3B), thereby providing a further security feature. The counterfeiter does not know which cracks happen to be and which ones are conscious of them
  • Protective layer 13 are coated. Covered areas can only be made visible with the specific method. For example, the examination and selection of the wavelength may be such that the crackle (or shrinkage) under the protective layer 13 is not visible to normal light. The protective layer 13 effectively shields the crackle. Only with the aid of other analysis methods (eg IR light at a specific wavelength, IR-A1 or IR-A2) the crackle pattern becomes visible. Also conceivable is the use of UV radiation, polarized light, fluorescence, luminescence and X-ray radiation to visualize a crackle pattern, wherein the scanning and angle of incidence can vary. Various test methods are shown in FIG. 3C. Overlaps with areas that have already been checked occur as well as for the screening of new test areas not yet contained in the database. In this way, and through the ongoing periodic update, a tamper-proof security medium is created. In a further embodiment, independent auxiliary areas can also be included or an overlap can be dispensed with.
