Abrégé

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.

Methods of manufacturing security documents and security devices, and corresponding products, provide a lenticular device effect in a first registration zone. Viewing its appearance from two different angles in this way, the relative positioning of the focussing element array and the image array can be judged to a high degree of accuracy. If the two arrays do not have the desired relative position, this will be clearly apparent since the different first and second images will not be captured at the first and second test viewing angles.

A security device including a surface relief microstructure which, in response to incident radiation, replays a hologram viewable within a viewing zone, the hologram including at least a first holographic image element in an image plane spaced from the surface of the microstructure. The device exhibits at least one further image in a plane spaced from the image plane of the first holographic element. On tilting the device, the first holographic image element exhibits apparent movement relative to the further image, which when expressed in radians, a rate of parallax movement per radian equals the spacing between phones and the product of the rate of movement and the included angle of the viewing zone defining a distance at least 20% of the dimension of the device in the direction of movement of the first holographic image element.

Abrégé

A security device comprises two or more regions (1, 2). Each region (1, 2) contains a material or combination of materials wherein the two or more regions exhibit substantially the same visible appearance under first viewing conditions and different visible appearances under second viewing conditions, the second viewing conditions. The second viewing conditions comprise a combination of a) visible light and b) substantially any UV wavelength.
