  • the invention relates to a film-like object with on both sides arranged, in the transmitted light through superimposition to a predefined Additional parts of the picture.
  • the film-like object with the forgery-proof image can be a packaging, a packaging material, a packaging aid, for example a label Safety part or a product itself.
  • a tamper-proof packaging or a packaging aid can guarantee originality serve, which enables the customer to recognize that that of product purchased by him is actually manufactured by the desired producer and has been packaged.
  • a counterfeit-proof packaging aid can include also can be used as a first opening guarantee, for example in the form of a label, a banderole or a sealing strip etc. which e.g. over a bottle cap or over the closure of a wide neck jar over which Seam between a lid and a container or over the zipper of a bag have been set.
  • When opening the corresponding Packaging will destroy the label, the banderole or the sealing strip and indicates that the first opening has already taken place. It is also possible, Fill or wrap items in an outer packaging, the outer packaging characteristic distinctive and difficult to copy Features that show that the packaging of the content at a certain suppliers.
  • holograms are on their surface provided with holograms or have color coding or invisible Characteristics on.
  • holograms To achieve a high level of security against counterfeiting in practice i.a. Proven holograms. Examples are hologram labels or cover foils with integrated holograms. The generation of holograms is associated with an enormous effort.
  • WO-A-00 00356 describes an object with an anti-counterfeiting security known surface area producing an optical effect.
  • the surface area with the optical effect has at least two image patterns held at a fixed distance by a transparent layer of material on, and when the viewing angle changes, the optical changes Perception of the overall picture created by the superimposition of the picture patterns.
  • the distance defined by the thickness of the transparent material layer between the image patterns and the distance between neighboring ones Image elements on which patterns are based are coordinated with one another in such a way that the image patterns show moiré interference.
  • EP-A-0 260 815 and US-A-5 488 664 disclose an object a first image pattern with high security against forgery and one with the object test film to be used made of a transparent material with a second image pattern to detect a fake image pattern.
  • the two Image patterns are essentially random across the board (Randomly) arranged, light and dark picture elements of the same number constructed in the same shape and in a basic area with an identical arrangement of the picture elements and into a selection area with predefined, not identical arrangement of the picture elements divided. With congruent overlay of the two image patterns by precisely positioning the image pattern the test film over the picture pattern of the object will not be in the case of one fake image pattern in the selection area creates a predefined image.
  • a security element known for banknotes is the division of a number in six parts, for example, with three parts on the front and on are printed on the back of the banknote so that when viewed in the Translucent the number as a whole is recognizable.
  • the security against counterfeiting results here from the difficulty of an exact printing of the front and Back, which requires extremely precise register printing.
  • the invention is based, with a film-shaped object of the type mentioned at the outset to further increase the security against forgery. moreover the object should be able to be checked for authenticity in a simple manner.
  • a first surface area in the form of a first image pattern and on the second page the object a second surface area in the form of a second Image pattern is arranged, the two image patterns essentially blanket of light and dark, randomly arranged picture elements of the same number and shape are constructed, the two image patterns in a basic area with an identical arrangement of the picture elements and into a selection area with predefined, not identical arrangement of the picture elements are divided, and wherein the two Image patterns lie congruently one above the other in transmitted light and in Selection area generate the predefined image.
  • An essential prerequisite for achieving a high level of counterfeit security is of course a high print quality and print fineness or high print resolution. Together with an extremely precise register print can with the object according to the invention in comparison to the objects known from the prior art with a test film higher counterfeit security can be achieved.
  • each picture element cell has rotational symmetry with a rotation angle of 180 °, 90 ° or 60 °, wherein the light and dark picture elements in a picture element cell are rotationally symmetrical and are alternately arranged in the direction of rotation, the picture element cells with regard to their angular position at random in the Image patterns are arranged, and wherein the two image patterns in a basic area with identical arrangement of the picture element cells and in a selection area with a predefined, not identical arrangement with regard to their angular position of the picture element cells are divided.
  • the light picture elements can be white and the dark picture elements To be black. But they can also be the same or different Colors built up. Another option 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.
  • the image patterns are preferably printed on the object, the Image patterns for the congruent overlay expediently by means of Register pressure is applied to the object.
  • the printing of the film-shaped The object is made using known printing processes. Instead of Conventional printing processes can of course also use other techniques such as. the laser coding method used to generate the image pattern become.
  • the predefined image generated by the image patterns in the selection area can for example a watermark, a number, a character, a font, a Logo or a halftone, but this list is not exhaustive.
  • a preferred area of application of the film-like material according to the invention lies in its use in the form of packaging, one Packaging material, a packaging aid, a security, a banknote, a Admission ticket or similar documents with high security against forgery.
  • the film-like object according to the invention can, for example, be any one Packaging material in the form of a packaging material or packaging aid be, with the invention according to both sides Patterns are applied.
  • sheet-like materials are papers and plastic films, e.g. based on polyolefins, such as polyethylenes or polypropylenes, polyamides, polyvinyl chloride, polyesters, such as Polyalkylene terephthalates and especially polyethylene terephthalate.
  • the Plastic-containing foils can be made of monofilms made of plastics, laminates two or more plastic films, laminates of paper and plastic films.
  • the individual layers of the sheet-like materials can be by means of Adhesives, laminating adhesives, adhesion promoters and / or by extrusion coating, Coextrusion or lamination, etc. are fixed to each other.
  • Adhesives laminating adhesives, adhesion promoters and / or by extrusion coating, Coextrusion or lamination, etc. are fixed to each other.
