A micro-optic device, including: a substrate; a plurality of image elements; and a plurality of focusing elements, each focusing element focuses light towards, or causes light to be diverged from or constructively interfere at a real or imaginary focal point, the focusing elements causing the image elements to be sampled so as to project imagery which is observable to a user from at least a first viewing angle, wherein a first focusing structure including at least a first group of the focusing elements and a first imagery structure including at least a first group of the image elements are integrated into a first unitary structure on a first side of the substrate.

Micro-optic device with integrated focusing element and image element structure

A security document, including: a polymer substrate; at least one print layer disposed on one or both sides of the polymer substrate; and a security feature including an image area embodied within the polymer substrate and at least partially covered by the at least one print layer, wherein the security feature is an optical security feature formed in the image area.

Security document including an optical security feature

A security element formed on a substrate having a printing side and a viewing side is provided, the security element including: a first image portion provided on the printing side of the substrate, the first image portion including one or more micro-image elements; a second image portion provided on the printing side and/or the viewing side of the substrate; and a plurality of focussing elements disposed on or in the viewing side of the substrate for observing the one or more micro-image elements; wherein the first image portion and the second image portion are integrated into at least one distinguishable security element when observed from the viewing side of the substrate.

Micro-imagery design integration

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.

Method of producing micro-image elements on a substrate

A micro-optic device, including: a substrate; a plurality of image elements in an image plane; and a plurality of focusing elements, each focusing element focusing light to a focal point on the image plane and magnifying any portion of an image element falling within the focal point to thereby produce an image pixel projected to a user at one or more viewing angles, the focal point having an extent smaller than the image element, wherein each image element includes an image sub-element having a different discernible level of brightness to elsewhere in the image element, the brightness of each projected image pixel being dependent on the proportion of the focal point filled with the image sub-element, and wherein each image sub-element has one or more attributes in the image plane, such that, from a given viewing angle, the brightness of each projected image pixel is dependent on each attribute of each image sub-element.

Micro-optic device projecting multi channel projected imagery

A micro-optic device, including: a transparent substrate; first lens elements on a first side of the substrate that reveal first image elements on a second side of the substrate; and second lens elements on the second side of the substrate that reveal second image elements on the first side of the substrate.
