Abstract:
Disclosed is a security document including an image area, a repeating image pattern in the image area of mutually spaced image elements at a mutual distance D and a layer of a plastics material overlying the image area and an array of lenses in the plastics material. The lenses are spaced at a mutual distance L which may be equal to D or which may differ from D, the array of lenses overlying only a part of the image area surface and are formed in the plastics material within an image contour. Within the contour an image may be observed such as a Moiré magnification or a Moiré effect of light and dark stripes. The lenses may be formed for instance by laser ablation or by imprinting.
