  • Patent number: 8906184
    Abstract: The present invention relates to a method for producing, for the depiction of a specified motif, a micro-optical depiction arrangement that exhibits a colored motif grid, composed of a plurality of micromotif elements, and a focusing element grid, composed of a plurality of microfocusing elements that reconstructs the specified motif when the micromotif elements are viewed.

  • Patent number: 8685488
    Abstract: The present invention relates to a method for producing a micropattern on a substrate (22), in which a substrate (22) is provided with a relief pattern (26, 28) that exhibits elevations (26) and depressions (28), and in which the elevations (26) and/or depressions (26) are arranged in the form of the desired micropattern, and with a printing tool, an imprint material (30; 34) is transferred to the relief pattern (26, 28), the viscosity of the imprint material (30; 34) being chosen such that the imprint material (30; 34) is selectively transferred either substantially only onto the elevations (26) or substantially only into the depressions (28) of the relief pattern.

  • Publication number: 20110027538
    Abstract: The present invention relates to a method for producing, for the depiction of a specified motif, a micro-optical depiction arrangement (30) that exhibits a colored motif grid, composed of a plurality of micromotif elements (50, 52), and a focusing element grid, composed of a plurality of microfocusing elements (40), that reconstructs the specified motif when the micromotif elements (50, 52) are viewed, and in the method, T1) a first substrate foil (32) having opposing main surfaces (34, 36) is provided, and an embossing lacquer (38) is applied on a first main surface (34) of the first substrate foil (32) and is embossed in the form of the focusing element grid composed of an at least locally periodic arrangement of a plurality of microfocusing elements (40), T2) a second substrate foil (42) having opposing main surfaces (44, 46) is provided, and an arrangement of colored micromotif elements (50, 52) is produced in the form of the motif grid on a first main surface (44) of the second substrate foil (42), and
