ABSTRACT:
The printed product comprises a carrier (1) provided with a relief on the surface thereof in the form of a plurality of grooves and a main visible image transmitted by an ordered screen, wherein said relief and the screen structure of the visible image are embodied in such a way that at least one additional image becomes manifest on the main image background when a lighting or viewing angle is modified. According to the invention, the angle and period (d) of the groove tracing is equal to the angle and lineature of the main image screen, and geometrical distortions whose value corresponds to the value of tonal gradations of the additional image are introduced into the relief and/or the main image screen structure without breaking the continuity of the pattern lines forming said screen and relief, whereby a nonuniform system of cross-points of the grooves with the screen pattern lines (8) forming said additional image is created.
