An anti-counterfeit support with a series of optical security elements () and with a metallized layer in which a non-individual pattern () with a diffractive surface () is in each case embossed for at least two of the optical security elements () and in each of which an individual pattern () is incorporated by laser lithography, wherein the individual pattern () has recesses () which form at least a partial pattern of the non-individual pattern () and are arranged with precise alignment on the non-individual pattern (), and the at least two optical security elements () each have an optical tilt effect between the individual pattern () and the non-individual pattern ().

Security label with tilt effect

Methods manufacture an optically variable security element by breaking down a first motif into first motif elements, assigning the first motif elements first directional degrees of reflection that encode the first motif, wherein a relief layer having a multiplicity of single visual elements having a respective single element surface is produced and divided into reflection areas, wherein first reflection areas of different single element surfaces are assigned to the first motif, and the first reflection areas associated with the first motif are provided with the first directional degrees of reflection.

Visually variable security element

The invention relates to a storage medium comprising a security feature, having a substrate (), at least one functional layer (), at least one feature which is written into the functional layer () and is visible when reflected and at least one feature which is written into the functional layer () and is visible when transmitted, at least one feature being individualized and at least one feature having a diffractive structure. The invention solves the technical problem of providing a larger variety of combinations of different security features. The invention also relates to a method for producing a storage medium comprising a security feature.

Storage medium comprising a security feature and method for producing a storage medium comprising a security feature

The invention relates to a method for calculating a computer-generated hologram, in which the pixel distribution of the computer-generated hologram is calculated, in which the pixel distribution of a macroscopic superstructure is calculated and in which the pixel distribution of at least one computer-generated hologram is interconnected with the pixel distribution of the macroscopic superstructure to form a pixel distribution to be written in a storage medium. Similarly, the invention relates to a method for writing the hologram, a storage medium and also a reading device. Therefore, both a computer-generated hologram and a macroscopic superstructure which can contain directly readable information can be brought together in a pixel distribution.

Method for calculating and producing a computer-generated hologram and also a storage medium with a computer-generated hologram and a reading device

The invention relates to a method of providing an article with identifying information, in which a hologram is provided from which at least first and second hologram patterns separated physically from each other can be reproduced. In this case, provision is made for the hologram to be produced in such a way that the first and second hologram patterns can generally be reproduced in one and the same direction but in different planes.
