The method involves applying micro-optical structures (6a,6b) on the layer lying under the layer consisting micro-optical structures, or inserting the micro-optical structures in the layer consisting micro-optical structures, by using intaglio printing. The layer, which consists of micro-optical structures, partially covers one or multiple layers. The display area or the effect area forms an optical effect. Both micro-optical structures and the display area, or effect area are applied by intaglio printing. Independent claims are also included for the following: (1) multi-layer body has a layer consists of micro-optical structures (2) a security document with a multi-layer body. |
