A security device (1) obtained by said method.

METHOD FOR PRODUCING PIGMENT FRAGMENTS WITH A PREDEFINED INTERNAL AND/OR EXTERNAL CONTOUR USING A CRACK-FORMING LAYER, AND PIGMENT FRAGMENTS

A method for producing pigments comprises the steps of creating a first layer on a substrate, structuring the first layer and detaching the pigments from the substrate. In the present case, the first layer is a crack-forming layer, so that the first layer is structured by the arising of cracks. Prior to detaching the pigments, a pigment layer is applied onto the first layer structured by the cracks.

METHOD FOR PRODUCING PIGMENT FRAGMENTS WITH A PREDEFINED INTERNAL AND/OR EXTERNAL CONTOUR, AND PIGMENT FRAGMENTS

A method for producing pigments having a specified contour, comprises the steps of creating a pigment layer on a starting substrate; detaching from the starting substrate; and structuring the pigment layer into a plurality of the pigments; characterized by bringing into contact the pigment layer with an intermediate substrate, wherein the pigment layer adheres at least in sections to the intermediate substrate; and separating intermediate substrate and starting substrate.

Methods of manufacturing security devices
10759213 · 2020-09-01 · ·

A security device manufacturing method includes: providing a substrate having a viewing region; providing an obscuring layer in the region; providing a first image; applying a mask to the first image and swapping colour components of first and second sub-images of the first image forming: a mask pattern, and a background pattern representing the unswapped colour components on their assigned side; and printing the mask and background patterns on corresponding layer sides. The layer reduces colours visibility on one side when the other side of the layer is viewed in reflection, and allows light through the region when the security device is viewed in transmitted light. When either side of the region is viewed in reflected light, the patterns on that side are dominantly visible and may be distinguished. When the region is viewed in transmitted light from either side, the region is transparent and the colour-composite image is visible.
