LENTICULAR NETWORK SAFETY DEVICE INCLUDING SEVERAL COLOR PATTERNS

摘要

Method of manufacturing a security device (1) comprising a first color pattern (A) visible along an associated viewing axis (Δα) and at least one second color pattern (B) visible along an associated viewing axis (Δβ) , comprising the following steps: assembly of an image layer (4) capable of forming at least one color pattern (A, B) by laser engraving, on top of a support (3), - laser engraving in the image layer (4) of the first color pattern (A), along its associated viewing axis (Δα), so that it can be seen through a lenticular array (7), - for each of said at least one second color pattern (B), laser engraving in the image layer (4), of said at least one second color pattern (B), along its associated viewing axis (Δβ), so that it can be seen at through a lenticular network (7). Safety device (1) obtained by this process.
