FIELD: printing industry.
SUBSTANCE: protection element with structure having optically variable properties and formed with embossed structure is described. Such embossed structure is combined with the coating contrasting with information medium surface so that at least some sections of the coating are seen when viewing the protective element at straight angle, but unseen at its being viewed at the specified acute angle. As a result, at alternating viewing of protective element at straight and angles, tilt effect is observed. Coating is formed with solid-line multicoloured screen-type pattern and reproduces at least one first information, and embossed structure is not solid and reproduces at least one second information; at that, the first information and the second information are partially mutually overlapped.
EFFECT: protection element provides increased protection degree against forgery and copying owing to masking the mismatchings occurring in colour register between elements.
