    摘要： A security device is disclosed including a substrate and one or more focusing elements or lens structures located on one side of the substrate. The security device includes a plurality of image elements associated with each focusing element wherein the image elements include at least first and second groups of image elements. Each image element may be composed of pixels located in an object plane to be viewable through the associated focusing element. Each image element comprises a diffractive grating element or sub-wavelength grating element which when illuminated by a light source generates a diffraction image observable at a range of viewing angles around the device. Image elements of the first group are visible in a first range of viewing angles and image elements of the second group are visible in a second range of viewing angles. The security device is particularly suitable for use on security documents, such as banknotes. A method of forming a security device is also disclosed.

    摘要： Embodiments relate to producing micro-image elements on a substrate for a security document, the method comprising: producing a plurality of microstructure units comprising three-dimensionally structured formations in a clear or pale relief layer on the substrate; and applying a coloured ink fluid to the relief layer, wherein the coloured ink fluid accumulates preferentially in regions of high surface curvature on each microstructure unit to provide contrasting areas of different ink density.

    摘要： A banknote comprising a substrate and a plurality of print layers printed by the same print process type printed onto the substrate, wherein at least one of the print layers is an indicia layer and at least one of the print layers is a tactile layer. Also, a method of producing a plurality of banknotes including: providing a substrate, in the form of a web, to a print press including a plurality of print units of the same print process type, wherein the web will pass through each of the plurality of print units, and at least part of the web is printed in a print run; printing a print layer on to the substrate at each of the plurality of print units, wherein at least one of the print layers is an indicia layer and at least one of the print layers is a tactile layer.
