Abstract
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.
Claims26
A method for producing an optically variable security element comprising:
- decomposing a first pattern into first subpatterns;
- assigning first directional reflectivities, which encode the first pattern, to the first subpatterns, producing a relief layer having a multiplicity of individual optical elements, each having an individual elementary surface, subdividing the individual elementary surface into reflectance regions;
- assigning first reflectance regions of different individual elementary surfaces to the first pattern;
- and
- providing the first reflectance regions assigned to the first pattern with the first directional reflectivities.
An optically variable security element comprising relief layer (50) comprising a multiplicity of individual optical elements, each having an individual elementary surface, wherein the individual elementary surfaces are subdivided into reflectance regions, a first pattern is decomposed into first subpatterns, first directional reflectivities, which encode the first pattern, are assigned to the first subpatterns, first reflectance regions of different individual elementary surfaces are assigned to the first pattern, the first reflectance regions assigned to the first pattern are provided with the first directional reflectivities.
