Abstract
A personalizable security document () includes a security feature () including a combination of a plurality of different features. In particular, the security feature () may include a laser-engraved image in a first layer (), and one or more fluorescent inks () in further layers (), which are disposed below the first layer. Optionally, a watermark () may also be provided in a lower layer (). A laser-engraving of the image is performed from a first side (S) of the substrate () such that patterns formed by the inks () are not affected. Under white light, the laser-engraved image can be viewed from the first side of the substrate, whereas multi-color fluorescence of the patterns can be observed from the second side (S) under UV light.
