A grating image having two or more achromatic grating fields (22, 24) having a viewing-angle-dependent visual appearance, each of which includes an electromagnetic-radiation-influencing grating pattern composed of a plurality of straight grating lines, - the grating fields (22, 24) being arranged in the form of a predetermined motif, - the grating patterns of the grating fields each being characterized by the grating pattern parameters orientation, spacing and profile of the grating lines, - in the grating fields (22, 24), at least one of the grating pattern parameters orientation, spacing and profile varying randomly over the surface of the grating field with a specified distribution such that the grating fields (22, 24) are each characterized by the grating field parameters average orientation, orientation distribution, average spacing, spacing distribution, average profile and profile distribution of the grating lines, and - each grating field having a preferred direction that establishes a viewing range from which the achromatic grating field appears visually having a matte, preferably silvery appearance, and - within the predetermined motif, at least the grating field parameter average orientation changing discretely from grating field (22, 24) to grating field (22, 24), characterized in that - the grating field parameters orientation distribution, spacing distribution and profile distribution are chosen in such a way that the predetermined motif conveys a relief- or lens-like three-dimensional impression that is determined by the three-dimensional form of a relief pattern, and in that - the grating field parameters average orientation, average spacing and average profile are chosen in such a way that the preferred direction of a grating field coincides with the corresponding local reflection direction of the relief pattern. - the grating fields (22, 24) being arranged in the form of a predetermined motif, - the grating patterns of the grating fields each being characterized by the grating pattern parameters orientation, spacing and profile of the grating lines, - in the grating fields (22, 24), at least one of the grating pattern parameters orientation, spacing and profile varying randomly over the surface of the grating field with a specified distribution such that the grating fields (22, 24) are each characterized by the grating field parameters average orientation, orientation distribution, average spacing, spacing distribution, average profile and profile distribution of the grating lines, and - each grating field having a preferred direction that establishes a viewing range from which the achromatic grating field appears visually having a matte, preferably silvery appearance, and - within the predetermined motif, at least the grating field parameter average orientation changing discretely from grating field (22, 24) to grating field (22, 24), characterized in that - the grating field parameters orientation distribution, spacing distribution and profile distribution are chosen in such a way that the predetermined motif conveys a relief- or lens-like three-dimensional impression that is determined by the three-dimensional form of a relief pattern, and in that - the grating field parameters average orientation, average spacing and average profile are chosen in such a way that the preferred direction of a grating field coincides with the corresponding local reflection direction of the relief pattern.
