A method for manufacturing a security paper includes an endless microlens thread having a top and an opposing bottom with the top provided at least in fractional regions with microlenses. A paper web having a predetermined ridge pattern is produced and defines ridge regions in which the microlens is embedded in the interior of the paper, and that exhibits, lying between the ridge regions, window regions in which the microlens thread emerges at the surface of the paper web. The microlens thread is introduced into the paper web and, at the same time, is joined on its bottom and, in the ridge regions, also on its top with the paper web. The paper web with the microlens thread forms the security paper. |
