Definitions

  • the invention relates to a film-like object with image parts arranged on both sides and complementing one another in transmitted light by superimposing a predefined image.
  • the film-like object with the forgery-proof image can be a packaging, a packaging material, a packaging aid, a security part designed for example as a label or a product itself.
  • a tamper-proof packaging or a packaging aid can serve as a guarantee of originality, which enables the customer to recognize that the product he has purchased has actually been manufactured and packaged by the desired producer.
  • a counterfeit-proof packaging aid can also be used as a first-time guarantee, for example in the form of a label, a banderole or a sealing strip, etc., for example, over a bottle cap or over the closure of a wide-mouth jar, over the seam between a lid and a container or over the zipper of a bag has been set.
  • the label, the banderole or the sealing strip is destroyed, indicating that it has already been opened. It is also possible, Filling or wrapping objects in an outer packaging, the outer packaging having characteristic, unmistakable and difficult to copy features, which show that the contents have been packaged by a particular supplier.
  • holograms on their surface or have color codes or invisible features.
  • Proven holograms examples are hologram labels or cover foils with integrated holograms.
  • the generation of holograms involves an enormous amount of effort.
  • WO-A-00 00356 an object is known with a surface area producing an optical effect to increase security against forgery.
  • the surface area with the optical effect has at least two image patterns held at a fixed distance by a transparent material layer, and when the viewing angle changes, the optical perception of the overall image generated by the superimposition of the image patterns changes.
  • the distance between the image patterns defined by the thickness of the transparent material layer and the distance between adjacent image elements on which the image patterns are based are matched to one another in such a way that the image patterns show Moire interference.
  • EP-A-0 260 815 and US-A-5 488 664 disclose an object with a first image pattern with a high level of security against forgery and a test film to be used with the object made of a transparent material with a second image pattern for the detection of a forged image pattern.
  • the two image patterns are essentially made up of light and dark image elements of the same number and shape, arranged randomly, and divided into a basic area with an identical arrangement of the picture elements and a selection area with a predefined, not identical arrangement of the picture elements.
  • a security element known for banknotes is the division of a number into, for example, six parts, three parts each being printed on the front and on the back of the banknote in such a way that the number as a whole can be seen when viewed in transmitted light.
  • the security against counterfeiting results from the difficulty of an exact printing on the front and back, which requires an extremely precise register printing.
  • the invention has for its object to further increase the security against counterfeiting in a film-shaped object of the type mentioned.
  • the object should be able to be checked for authenticity in a simple manner.

  • An essential prerequisite for achieving a high level of counterfeit security is, of course, high print quality and print fineness or high print resolution. Together with an extremely precise register print, the object according to the invention can be used to achieve a higher level of security against forgery than the objects known from the prior art with a test film.

  • the light picture elements can be white and the dark picture elements can be black. But they can also be made up of the same or different colors. Another possibility is that the picture elements have a color that is only visible in UV or IR light and are therefore only visible in UV or IR light.

Abstract

L'invention concerne un objet (10) en forme de feuille comportant des images partielles qui sont placées des deux côtés et se complètent par superposition vu par transparance en donnant une image prédéfinie ayant une grande protection contre la falsification. Pour augmenter la protection contre la falsification sur une face de l'objet (10), une première zone superficielle se présentant sous la forme d'un premier motif d'image (12) est placée sur une première face de l'objet (10) et une deuxième zone superficielle se présentant sous la forme d'un deuxième motif d'image (22) est placée sur la deuxième face de l'objet (10). Les deux motifs d'images (12, 22) sont constitués d'éléments image (14, 16; 24, 26) disposés sensiblement sur toute la surface claire et sombre selon le principe aléatoire, ces éléments image étant de nombre et de forme identiques. Les deux motifs d'images (12, 22) comportent une zone de base (32) avec une disposition identique des éléments image (14, 16; 24, 26) et une zone de sélection (30) avec une disposition prédéfinie, non identique des éléments image (14, 16; 24, 26). Les deux motifs d'images (12,22) se superposent en coïncidant vu par transparence et produisent l'image prédéfinie dans la zone de sélection (30).
