Definitions

  • the invention relates to a method for producing a security feature on a security paper and use.
  • Security paper is used to make banknotes, but also for passports ; Identity cards, credit cards, check forms, securities, stamps or the like.
  • the security papers for the different products differ, for example, in terms of paper resistance requirements.
  • Security paper can be produced individually, but is also available as pre-produced merchandise in various forms.
  • Security paper provides protection against counterfeiting.
  • the security paper is regularly provided with security features after paper production.
  • raw material compositions containing cotton or bleached pulp are used, whereby the cotton content may be 90% or more.
  • the object of the invention is to specify a method for producing a security feature on a security paper, which enables the security feature to be formed in various configurations in a simple and efficient manner.
  • a method for producing a security feature on a security paper according to the independent claim 1 is provided. Furthermore, the use of the produced security paper according to claim 12 is provided. Further embodiments are the subject of dependent claims.
  • a method for producing a security feature on a security paper in which a security paper is produced by means of a paper-making process and in this case a color security on the security paper. is formed keitsmerkmat.
  • a dye is at least locally applied to a not yet or not yet finally dried intermediate product of the security paper by means of a paint application process. The intermediate is then dried or further dried to produce the security paper.
  • the use of the security paper produced is provided with a security feature for producing a security document such that a security feature of the security document is formed with the security feature of the security paper.
  • the color security feature is formed during the production of the security paper, whereby security paper can be produced which already has the color security feature.
  • the security paper thus produced may then be used to produce a security document in which the color security feature generated during papermaking constitutes a document security feature.
  • the security paper produced can then be equipped with further security features, as they are known as such in various embodiments.
  • the application of the dye for producing the color security feature takes place in the course of the papermaking process before drying of the paper fibers begins and / or embedded in the drying process before the paper fibers in the paper machine are finally dried and the paper is removed, in particular can be rolled up.
  • an endless paper web is formed from the paper fibers in the paper machine. Before the endless paper web is finally dried, Iokaie paint application.
  • the dye can be applied by means of a non-contact paint application process.
  • non-contact paint application there is no contact between the device for the application of paint and the not yet or not yet finally dried intermediate product for the security paper instead.
  • the dye can be sprayed in the non-contact paint application method.
  • the inkjet printing process can be used.
  • a narrow lines forming color beam can be used.
  • the dye may at least partially extend after being applied to the intermediate. Due to the wetness or the moisture of the intermediate product, partial application of the applied dye occurs in this exemplary embodiment, which can be used purposefully for the individual formation of the color security feature, by using a different course in the production process for different security features, for example by that the degree of wetness or moisture of the intermediate to which the dye is applied is chosen differently.
  • the dye may be applied while an intermediate, scooped pulp is placed on a dryer.
  • the paper pulp may in this case be arranged on a screening device which assists the leakage or discharge of moisture from the pulp of paper being produced.
  • the drying device may be part of a paper machine, which consists of several sections for different process steps. For example, one or more of the following sections may be provided: headbox, screen / former lot, press batch, pre-dryer lot, linen press, after-dry lot and reel-up. Different types of paper machines may be used, for example, fourdrinier, fourdrinier, or skewers, which differ in the nature of the sheet forming system.
  • the dye can be applied to one or both sides of the intermediate product, whereby one or both sides a color security feature can be formed.
  • the dye can in this case be applied to one or both sides in local areas, that is to say the surface of the intermediate product on one side and / or the other side is not completely detected.

  • the dye is applied in this embodiment after a pre-dried intermediate product is present. For example, this can be done in the paper machine after the pulp has been pressed and pre-dried, that is still has a moisture content. In the case of applying the dye to the predried intermediate, it can be avoided that the dye penetrates completely into the paper pulp. Volume areas of the pulp may remain free of the dye.
  • the pulp may be dried on one side by means of a dryer, such as a blower, and the dye may be applied to an opposite not yet dried side, whereby only local or limited distribution of the dye can be achieved.
  • the application of the dye to the predried intermediate may allow and / or ensure controllable application to only one side of the intermediate.
  • the degree of moisture of the intermediate can be adjusted. This may in particular make it possible to control the degree of bleeding of the applied dye.
  • the individual training of the color security feature can be controlled.
  • the predried intermediate product may be pre-dried to an extent of at least 50 volume percent of the total volume of the pulp, ie at least half.
  • the dye may be applied to a predried intermediate, one or both sides, which is pre-dried on the opposite flat sides of the pulp, but not in a central region between the dried flat sides.
  • the dye may be applied to a dried section of the predried intermediate.
