Definitions

  • a product of value or security and a method for producing a product of value or security are described here.
  • the value or security product can be formed, for example, by a card or a data page for a passport.
  • a valuable or security product which is particularly suitable for being provided with an individualizing security feature in a decentralized production facility, for example in the form of a multicolored facial image of a person.
  • the value or security product has a product body with two outer sides and comprises a non-individualizing security print, as well as the individualizing security feature.
  • the security print and the security feature are printed overlapping in a printing plane.
  • the product body is coated with a protective or topcoat on the outside, which has the individualizing security feature and the security print. The underlying security feature is thereby secured.
  • the protective or topcoat gives the document abrasion resistance and protection from scratches or other damage.
  • An improved value or security product should have an increased security against forgery.
  • a valuable or security product which has a flat base body with a first outside and a second outside opposite the first outside.
  • the valuable or security product has a security feature which is arranged in an inner region of the base body or on the first outside of the base body.
  • the valuable or security product has a lacquer layer arranged on a first partial area of the first outer side, which is formed over the entire surface, as well as an arrangement of several lacquer elements arranged on a second partial area of the first outer side, the security feature with the first partial area and / or is formed at least partially overlapping with the second partial area of the first outer side.
  • the production of the arrangement of the lacquer elements specified here is comparatively complex, so that increased security against forgery can be achieved through the arrangement of the lacquer elements.
  • the second sub-area Due to the different design of the two sub-areas, it can be achieved that these create a different visual impression.
  • the second sub-area has a different / rougher feel than the full-surface lacquer layer due to the lacquer elements.
  • the arrangement of the lacquer elements makes it possible to form a surface area of the valuable or security product which provides a tactilely detectable identifier or information for a user.
  • lacquer elements makes it possible to achieve that the surface area of the valuable or security product thus formed has an appearance that resembles that of an orange peel.
  • the full-surface lacquer layer and the lacquer elements consist of the same lacquer material.
  • the lacquer elements By forming the lacquer elements, it can be achieved that these appear matt or light diffusely reflecting, while the full-surface lacquer layer, in contrast, appears more glossy and / or reflects a greater amount of light than the lacquer elements.
  • the lacquer material from which the lacquer layer and the lacquer elements are formed is a clear lacquer.
  • the two sub-areas do not overlap.
  • a lacquer can in principle be designed to be harder and / or more temperature-resistant than a film, for example a PC film or a PET film, so that the lacquer can provide particularly suitable protection for the first outside against scratches.
  • the security feature is a personalizing security feature, that is to say, for example, a facial image or a photo of a face of an intended user of the valuable or security product.
  • the security feature is formed so as to be in contact with the lacquer layer and / or the lacquer elements. This further increases the security against forgery, because an attempt to manipulate the security feature practically inevitably leads to the destruction of the lacquer layer or the lacquer elements.
  • the first partial area of the first outside and the second partial area of the first outside completely cover the first outside. In this way it can be achieved that a relatively large proportion of the first outer side is covered by the lacquer layer or the lacquer elements.
  • the first partial area or the full-surface lacquer layer is designed to be congruent with the security feature.
  • the first partial area or the full-area lacquer layer is slightly larger than the security feature.
  • the lacquer layer can project beyond the security feature on all sides by an overhang that is smaller than approximately 10% of the maximum extent of the security feature.
  • first sub-area and the second sub-area are designed to be complementary to one another.
  • the first and the second partial area only partially cover the first outer side. In this way, a third partial area can be formed, on which no lacquer is arranged.
  • such an area without lacquer is provided for the formation of embossed digits and / or letters and / or for a chip and / or a security feature arranged in an inner area of the base body. This is suitable, for example, in the case of a credit card.
  • the first sub-area and the second sub-area jointly cover a security feature which is arranged in an inner area of the base body and / or on an outer side, the lacquer layer and / or the lacquer elements being arranged on the outer side.
  • a blackening produced by laser treatment is formed in an inner region of the base body, at least partially within the projection of the security feature.
  • the lacquer elements are arranged at least approximately irregularly and / or are designed differently in size and / or shape.
  • the arrangement of the lacquer elements thus gives the viewer a chaotic or arbitrary impression.
  • distances of different sizes can be formed between the lacquer elements.
  • some of the lacquer elements for example 20% to 30% of the total arranged lacquer elements, have an identical shape and / or size and / or can be arranged at regular intervals on the outside, while another part of the lacquer elements, for example 70 % to 80% of the total arranged lacquer elements, arranged irregularly, and / or designed differently in size and / or shape.
  • the variant is such that the lacquer elements are shaped at least approximately identically and / or have a uniform size and / or are arranged in a uniformly distributed manner.
  • the number of lacquer elements is greater than ten or twenty or thirty or forty or fifty.
  • the number of lacquer elements can also be three digits or greater than one hundred. As the number of lacquer elements increases, the security against forgery is generally further increased.
  • At least 30% of the lacquer elements have an extension or width, measured parallel to the first outer side, which is smaller than 500 ⁇ m, in particular smaller than 200 ⁇ m. This makes production more difficult and thus further increases the security against forgery.
  • spacings between approximately 10 ⁇ m and 200 ⁇ m are formed between adjacent lacquer elements. This also makes replication more difficult and thus further increases the security against forgery.
  • the lacquer elements have an application thickness or extension perpendicular to the first outer side that is between 10 ⁇ m and 20 ⁇ m.
  • the lacquer layer has an application thickness or extension perpendicular to the first outer side which is between 5 ⁇ m and 10 ⁇ m.
  • the full-surface lacquer layer has a uniform thickness or application thickness.
  • the lacquer elements have a uniform thickness or application thickness.
  • the application thickness of the lacquer layer is smaller than the application thickness of the lacquer elements.
  • the base body has several layers.
  • the base body can have a core layer composed of 2 to 4 layers and at least two transparent layers each on both sides of the core layer.
  • at least one transparent layer with laser-sensitive properties and / or with additives to be blackened by laser light, for example with carbon, can be arranged between the outside of the base body and the core layer.
  • the material of the base body can have a softening temperature which is lower than a softening temperature of the lacquer material of the lacquer layer and / or of the lacquer elements.
  • at least one of the layers is printed at least in sections to be opaque or opaque.
  • at least one further layer consists of a transparent material.
  • one of the layers can be printed in an opaque or opaque manner, the remaining layers of the base body each consisting of a transparent material.
  • the value or security product can have a third partial area on the outside which is free from paint.
  • This third partial area can have or reshape a security feature which is arranged in an inner area of the base body or on the first outside of the base body.
  • an inner layer is printed, marked and / or personalized.
  • at least one of the two outer sides is marked and / or personalized.

  • step (ii) after the security feature has been printed, the security feature is dried on by UV irradiation without the security feature in this case being completely cured.
  • the lacquer layer and / or the lacquer elements are printed on in step (iii) as long as the security feature has not yet hardened. In this way, a connection can be achieved between the security feature and the lacquer layer and / or the lacquer elements, which further increases the security against forgery.
