Abstract
The application provides a kind of stereo anti-fake microlens sheet, and the microlens sheet includes：Microlens layer, multiple miniature convex lens including being arranged in array format, it is arranged at least one product identification in the white space between multiple miniature convex lens, formed by transparent material and be arranged on the layer of the focal length below microlens layer, it is arranged on focal length layer lower section and multiple first three-D patterns of array format is arranged in the arranged direction identical direction with multiple miniature convex lens, and be formed as covering the coat of microlens layer and product identification by transparent material, coat is used to hide the miniature convex lens for protruding from microlens sheet surface, play a protective role simultaneously.The microlens sheet of the application is presented under the conditions of adjusting the structure of each part so that the first three-D pattern included is only specific according to being precisely calculated, so as to have the advantages that to be difficult to replicate or copy, as anti-counterfeiting mark, with good market prospects.
Description
Technical field
The application is related to a kind of anti-counterfeiting mark of use lenticule, more particularly, to false proof micro- with laminated construction
Lenticular sheet.
Background technology
At present, commonly using the cubic light that space pattern is visually presented using moire interference in anti-counterfeiting mark field
Piece is learned, this stereoptics piece produces cloud by being printed on the focal length of transmittance thin slice layer in micro- pattern of regular arrangement
Line interferes (moir'e interference) phenomenon, and then three-dimensional pattern is presented.In the manufacture of traditional stereoptics piece
In, the arranging density of lenticule and the thickness of focal length layer are calculated according to the refractive index of lenticule, radius of curvature and arrangement spacing
Degree, in the three-D pattern of focal length printed below mark action of layer, and the stereoptics piece produced by this technique is only
The pattern below lenticule can be just seen under the observation condition at positive visual angle, when with inclined view, space pattern
It will thicken or be difficult to recognize, and more can not realize multiple stereoeffect with the change of position.Simultaneously as micro- in tradition
Electroforming (Nickel Electroforming) technique used in the manufacture of lens has the shortcomings that to be easy to replicate, therefore compared with
Anti-counterfeit field is applied to less.
For other anti-tamper security technologies such as coin, although can be used the supplementary means such as ultraviolet that common observation is presented
Under the conditions of not shown implicit pattern so as to realize antifalse effect, but its two-dimensional pattern used equally has and is easy to what is replicated
Shortcoming.
In addition, although stereoptics version due to it has a good design effect and be widely used for stationery class, publication,
The planographic marking field such as printed article or advertisement, but be due to that its concealment effect is not good and be difficult to identify as anti-fake certificate
Use, moreover, still there is certain difficulty when by for verifying that micro- pattern of the true and false is embedded in inside lenticule.
Utility model content
To overcome at least one deficiency of the prior art, the application provides one kind and can presented under different observation conditions
The three-dimensional microlens sheet of hiding stereo anti-fake pattern.
It may include according to the stereo anti-fake microlens sheet of one embodiment of the application：Microlens layer, including with row side
To and the horizontally disposed hemispheric multiple miniature convex lens of column direction, the white space being arranged between multiple miniature convex lens
In at least one product identification, formed by transparent material and be arranged on the focal length below microlens layer layer, be arranged on focal length
Layer lower section and multiple first three-dimensionals that array format is arranged in the arranged direction identical direction with multiple miniature convex lens
Pattern, the arranging density of multiple first three-D patterns be configured to the 97.5% of the arranging density of multiple miniature convex lens to
102.5%.Stereo anti-fake microlens sheet may also include：Multiple two dimensions between focal length layer and multiple first three-D patterns
Pattern, and between multiple two-dimensional patterns and multiple first three-D patterns and with the arrangement side with multiple miniature convex lens
Multiple second three-D patterns of array format are arranged in identical direction.By adjust microlens layer and focal length layer thickness,
The arranging density of multiple miniature convex lens or the arranging density or spacing of arrangement spacing and multiple first three-D patterns cause many
Different visual effects are presented in individual first three-D pattern under different observation conditions.
Coat may also include according to the stereo anti-fake microlens sheet of one embodiment of the application, the coat is by saturating
Bright material is formed as covering microlens layer and product identification, and coat refractive index be multiple miniature convex lens refractive index
82.54% to 97.14%.
In the embodiment of the application, pass through the white space print product mark between multiple miniature convex lens
Know pattern to set product identification with being layered for false proof space pattern, so that in the presentation effect of the first three-D pattern
It still is able to clearly display product identification pattern when changing.
In addition, by setting clear coat layer above microlens layer so that protruded in the upper surface of microlens sheet
Lenticule is visually invisible, and makes the surface more flat smooth of microlens sheet, while also being lifted as protective layer micro-
The hardness of lenticular sheet, prevents it is scraped by exterior object from influenceing the identification of pattern.
According to the above-mentioned technical proposal of the application, by the thickness, the multiple miniature convex lens that adjust microlens layer and focal length layer
The arranging density or spacing of the arranging density of mirror or arrangement spacing and multiple first three-D patterns can realize it is following at least one
Effect：
1st, there is colour switching and common 3-D effect under common observation condition, and during by eye close to microlens sheet
It can be seen that for the first false proof three-D pattern；
2nd, when being observed by camera, it can be seen that the first three-D pattern that can not be observed with bore hole is presented clearly
Stereoeffect；
3rd, when using ultraviolet light source shines microlens sheet, it can be seen that can not be observed under common observation condition
Clearly stereoeffect is presented in first three-D pattern；
4th, when it is at an acute angle with planar shaped where microlens sheet to change visual angle, it can be seen that in front during direct-view without
Clearly stereoeffect is presented in the first three-D pattern that method is observed.
