In some examples, a security element includes a substrate that, on one of its sides, includes at least one security feature extending over a first area, the security feature being configured in the form of a three-dimensional intaglio structure. A first ink group in the security feature includes a plurality of first raised image elements containing intaglio printing ink of the first color, and at least one second ink group in the security feature includes a plurality of raised image elements containing intaglio printing ink of a second color that differs from the first color, and these are provided and arranged offset and spaced apart from one another such that they form an optically variable structure and/or at least some of the mutually adjacent image elements, which differ from one another in the color, occlude and/or expose one another to varying degrees from a varying viewing angles.
