Abstract (en)
[origin: WO2018172750A1] A security device comprises an array of elements (12) of a first image (I1) arranged across an array area in accordance with a pattern which is periodic at least in a first dimension, the first image elements being spaced from one another by regions (14). A second image (l2) underlies the array of elements (12) of the first image, the second image extending continuously across the array area. Elements of the second image (l2) are exposed through the regions (14) between the first image elements (12), such that the elements of both images can be viewed from the same side of the image array, and wherein the security device is one of a set of such security devices each of which has the same first image and a different second image.
