Abstract: A method includes using a lenticular image having a lens grid composed of a plurality of microlenses and a metallic motif layer arranged spaced apart from the lens grid; the refractive effect of the microlenses defines a focal plane and the metallic motif layer being arranged substantially in the focal plane; a line width is chosen for the demetalized sub-regions to be produced in the metallic motif layer; a marking laser source having a laser wavelength λ is selected such that the resolving power D(λ) of the microlenses of the lenticular image at the selected laser wavelength λ substantially corresponds to the line width of the demetalized sub-regions to be produced; and the metallic motif layer is impinged on through the microlenses with laser radiation of the marking laser source to produce demetalized sub-regions in the metallic motif layer.

Abstract: A method for manufacturing the security element transfer material, a method for the register-accurate transfer of security elements from the security element transfer material to a value document substrate, and a value document which was equipped with a security element while employing the security element transfer material, wherein the security element transfer material has a temporary carrier material and a plurality of security elements and a plurality of register mark elements which are arranged on a main area of the temporary carrier material and have a layered composite structure. Each register mark element represents a register mark or contains a register mark, and each register mark is assigned to at least one security element. Apart from the security elements and the register mark elements, the temporary carrier material is free from layered composite material.
