Abstract
A personalizable security document (10) includes a security feature (3b) including a combination of a plurality of different features. In particular, the security feature (3b) may include a laser-engraved image in a first layer (16), and one or more fluorescent inks (7a, 7b) in further layers (27a, 27b), which are disposed below the first layer. Optionally, a watermark (8) may also be provided in a lower layer (18). A laser-engraving of the image is performed from a first side (S1) of the substrate (1) such that patterns formed by the inks (7a, 7b) 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 (S2) under UV light.
