Definitions

  • the present invention relates to a method for producing a security element for a security or value document, for example for a banknote or the like, as well as a correspondingly produced security element and a security or value document with such a security element.
  • watermarks are known. These are usually introduced in the production of the substrate from which the security element is manufactured.
  • the substrate used is usually a fiber-based substrate, for example paper.
  • a watermark is easily recognizable when looking through the security element, since in the region of the watermark the opacity of the substrate is modified compared to the environment, ie in the area of the watermark the light transmission is higher than in the surrounding area.
  • a watermark is generated by means of a thickness reduction of the substrate.
  • the watermark ink may contain substrate-lubricating binder components such as glycerine which cause the substrate in the region in which the watermark ink has been applied and penetrate the substrate over the entire substrate thickness to have increased transparency compared to the surrounding area ,
  • Object of the present invention is to propose a security element and a method for producing such a security element, which comprises a watermark and which has an increased security against forgery compared to a watermark.
  • the invention is based on the basic idea of producing a watermark by means of a watermark color and registering precisely by means of a suitable substance to apply a further motif to the substrate, which can be seen in plan view.
  • This further motif and a motif represented by the watermark can in combination produce an incident light / transmitted-light effect which, together with the registration accuracy, is easily recognizable and difficult to falsify.
  • a substance is applied locally on a first surface of the substrate in such a way that, when the first surface of the substrate is viewed in plan view, a first motif formed by the substance becomes recognizable.
