FIELD: image forming devices.
SUBSTANCE: present invention relates to object containing its surface area suitable for plurality of images displaying. Each of these images can be visible from separate direction so, that during viewing of one of images other image are not visible and do not prevent visibility of observed image. Flat area contains multiple recesses with small texture, uniformly distributed on area surface. Every recess has multiple side edges (1.1.1, 1.1.2, 1.1.3, 1.1.4), at least one edge on image. Every edge (1.1.1, 1.1.2, 1.1.3, 1.1.4) is connected either to first level of light, or to level of light, different from first one. Edges (1.1.1, 1.1.2, 1.1.3, 1.1.4), which determine image and connected to first level of light, have similar orientation and inclined relative to surface, on which recess is arranged, and this orientation differs from orientation of edges (1.1.1, 1.1.2, 1.1.3, 1.1.4) of another separate image.
EFFECT: enabling higher protection against counterfeit.
