A security device 10 and a method of manufacturing a security device is provided, which comprises: (i) providing a transparent substrate 2; (ii) applying a curable transparent material (for example a UV-curable material) to a region of the substrate; (iii) in a first curing step, partially curing the curable transparent material by exposure to curing energy E (for example 10-70% of a total curing energy dose); (iv) applying a layer of a reflection enhancing material 12 (for example a dispersion of reflective particles in a binder) to the curable transparent material; (v) forming the partially cured transparent material and the layer of reflection enhancing material such that both surfaces of the layer of reflection enhancing material follow the contours of an optically variable effect generating relief structure 15; and (vi) in a second curing step, fully curing the formed transparent material by exposure to curing energy such that the relief structure is retained by the formed transparent material. |
