A personalized security document (10) includes a first personalized image (5) and a second personalized image (8) as part of a security feature (3). The second personalized image (8) is arranged at a position that corresponds to the first personalized image (5). For example, the first personalized image (5) is laser-engraved in a first surface (6a) of a laser-engravable material layer (6). The second personalized image (8) may be formed by laser-engraving on a second surface (6b) opposite to the first surface (6a) of the laser-engravable material layer (6). Alternatively or additionally, the second personalized image (8) may be formed by printing onto a substrate (1) of the security document (10) of the laser-engravable material layer (6) to form a personalized variable watermark.
