Plasmonic color printing by fabricating a Fabry-Pérot (F-P) resonant structure on a substrate. The F-P resonant structure includes a reflective layer, a dielectric spacer layer overlying the reflective layer, and a random metal film (RMF) layer that overlies the dielectric spacer layer and has a nanostructure. The F-P resonant structure is photomodified using a laser, which induces changes in the nanostructure of the RMF layer. These changes are tailored to produce desired changes in the light-scattering and reflective properties of the RMF layer. As a result, by tailoring the photomodifications and the changes it produces, the color-generated by illumination filtered through and reflected from the F-P resonant structure can be tailored to a desired hue.

A security document (10) includes a first security element (40) embedded in a substrate (1) of the same. The first security element (40) is part of an optically variable security feature (3) and is not visible when the security document (10) is viewed at a first observation angle, but becomes visible when the security document (10) is viewed at a second observation angle. This is achieved by hiding the first security element (40) behind an opaque layer (31) of the substrate (1), and providing appropriate openings (42) in the opaque layer, with which the security element (40) is aligned such that it can only be seen when the security document (10) is viewed at the second observation angle.The openings (42) can be through-holes (43, see figures 2, 3) or zones without an opaque material (39, see figures 4, 5).
