Embodiment Construction

[0240] combine images

[0241] Figure 1 shows that by combining multiple interleaved images I 1 , I 2 ,..., I n are added together to form an example of combined image I. Each interlaced image I i by the direction X I Interlaced image lines i arranged in a periodic manner on i formed and have the same width l constant over the entire length i . The interlaced images have the same period S.

[0242] like Figure 1B as shown, Figure 1B Indicates the details of the combined image, the interlaced image line i 1 to i n Including micropatterns 7 (such as Figure 1B shown), in particular formed by micropatterns 7. interlaced image I i line i i The micropatterns 7 can be the same.

[0243] Preferably, lines i belonging to different interlaced images 1 to i n The micropatterns 7 have different appearances, in particular different shapes and / or different hues, opacities, brightness, gloss and / or saturation. Preferably, lines i belonging to different interlaced imag...

Abstract

The invention relates to a security article comprising a display grating (4) and a combined image (I); or an assembly comprising a security article (10) comprising a display grating (4) and another object (100) ) and the combined image (I), and the other object (100) includes or forms the other of the display grating (4) and the combined image (I), the combined image is composed of a plurality of interlaced images (I 1 to I n ), each interlaced image (I 1 to I n ) and / or to display that the raster consists of multiple elements (i 1 to i n ,p 1 to p n , 5a, 5b), the display grating (4) is such that when it is placed on top of the combined image (I), it can be viewed by moving the display grating (4) relative to the combined image (I) and / or by changing the viewing angle Observe various display images (I r ), the display images each include a respective interlaced image I 1 to I n A specific ratio of (P 1 ;…;P n ), and elements (i 1 to i n ,p 1 to p n , 5a, 5b) consist of one or more micropatterns (7).

Description

technical field [0001] The present invention relates to the field of security articles. Background technique [0002] In order to prevent forgery or tampering and to increase the level of security, it is known to use security elements applied on surfaces or to introduce loose parts or as windows into security objects (such as labels, packaging, especially for pharmaceuticals, food, cosmetics, electronic part or spare part label, packaging). [0003] In particular, security items can be selected from payment means (such as banknotes, bank cards, checks or restaurant vouchers), identity documents (such as ID cards, visas, passports or driving licenses), security cards, lottery tickets, transport passes or show tickets to choose from. [0004] It is known from patent applications EP 2 367 695, EP 2 585 308 and EP 2 586 014 and from patent EP 2 454 102 to mask the effect of an interlaced image by a display grating, allowing when the display raster and the image are superimpose...
