A method and apparatus for in-line manufacture of a security document with a structured security element is provided in which a continuous web of document substrate (1) is fed through a series of processing stations (2, 3, 4, 5, 25, 26). The processing stations include a station (5) for forming a structured security element (17;37) in a radiation sensitive coating applied to the document substrate (1), and at least one station (25, 26) for applying at least one additional layer (13, 14, 15; 32) to the document substrate (1) excluding the security element area (16; 36). In a security document manufactured with the method or apparatus, the additional layer or layers (13, 14, 15; 32) have a combined thickness (7) which is preferably substantially equal to the height (H) of the structured security element or which differs from the height of the structured security element (17, 37) by a predetermined amount.
