Therefore, it is generally problematic if the security paper is to be printed with one or more further print layers above such an optically variable security element, for example, to produce a value document, since the detectability of the optically variable effect can be impaired or completely prevented. In order nevertheless to ensure the recognizability of the optically variable effect, a cutout in the region of the optically variable security element could be provided in the further printing layer. On the one hand, however, this would impair the design freedom for the printed image to be applied.
