摘要： A method and system for writing a label (defined within a predetermined region of the sample 110), the label displaying a visible layout of light-modified regions in a predetermined spatial arrangement. The method comprises: modifying regions of a material within the label using light, wherein the modifying comprises using light of a first polarisation state to provide photo-induced optically active regions of a first type having a first optical activity state which is characteristic of having been formed by light of the first polarisation state, in order to encode covert information in the label using the locations of the first type of light-modified regions within the spatial arrangement of the label.

摘要： A security insert with at least one optically recognizable character and at least one tactilely detectable character for an identity document comprises at least a first at least partially transparent layer which has blackenings which form at least one optically recognizable character. A varnish arrangement forming at least one tactilely detectable character is disposed on a layer of the security insert. The at least one optically recognizable character is, at least from the perspective of an observer of the security insert, partially overlaid by the at least one tactilely detectable character, wherein at least a portion of the outer contours of the at least one tactilely detectable character is optically recognizably reproduced by the optically detectable character.

摘要： A laminate includes a recording layer, a translucent front covering layer and a security foil laminated between the recording layer and the front covering layer and sealed in the laminate. The security foil has a thickness that is ⅕ or less the thickness of the recording layer to prevent or reduce falsification reusing the security foil. The security foil includes a relief layer having a relief surface and a protective layer covering the relief surface. In the thickness direction of the laminate, the protective layer adheres to the recording layer and the relief layer adheres to the front covering layer. The adhesion strength between the security foil and the recording layer is higher than the adhesion strength between the security foil and the front covering layer.

摘要： According to examples, a substrate may be moved through a magnetic field, in which the substrate includes a fluid carrier containing magnetically-orientable flakes. The magnetic field may influence the magnetically-orientable flakes to be respectively oriented in one of multiple orientations. In addition, during movement of the substrate through the magnetic field, radiation may be applied onto a plurality of selected portions of the fluid carrier through at least one opening in a mask to cure the fluid carrier at the plurality of selected portions and fix the magnetically-orientable flakes in the plurality of selected portions at the respective angular orientations as influenced by the magnetic field.

摘要： An example of a computer-readable medium storing machine-readable instructions. When executed, the machine-readable instructions may cause a processor to control a laser to print a test pattern. The test pattern may be scanned to determine visibility of pixels. The power of a laser may be adjusted based on the visibilities to print a security pixel.
