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.
