Embodiment one, a kind of anti-counterfeit structure, as shown in Figure 1, comprising:
The anti-counterfeiting characteristic layer 11 be superimposed from top to bottom and N number of color layers 12, N are more than or equal to 2; Such as Fig. 1 comprises first color layers 121 and second color layers 122, and anti-counterfeiting characteristic layer 11 is on the surface of first color layers 121, and first color layers 121 is on the surface of second color layers 122;
Described anti-counterfeiting characteristic layer 11 comprises one or more first area 13 at least penetrating described anti-counterfeiting characteristic layer 11; It is integer between 0 ~ N that each described first area 13 penetrates M described color layers 12, M at random, comprises 0 and N; The number of the color layers 12 that different first areas 13 penetrates is similar and different; In such as Fig. 1, the first area 13 on the left side has penetrated anti-counterfeiting characteristic layer 11 and first color layers 121, present the color on second color layers 122 surface, 13, the first area on the right has only penetrated anti-counterfeiting characteristic layer 11, presents the color on first color layers 121 surface;
Described first area 13 forms anti-counterfeiting information separately, and/or jointly forms anti-counterfeiting information with the region beyond the first area 13 on described anti-counterfeiting characteristic layer 11.
The present embodiment can make the anti-counterfeiting information on anti-counterfeiting characteristic layer 11 present the color of different colours layer at random, and what in such as Fig. 1, the first area 13 on the left side and the first area 13 on the right presented is exactly different colors.It should be noted that, in some cases, anti-counterfeiting information also likely only presents a kind of color, in a such as anti-counterfeit structure all first areas 13 to penetrate the number of plies at random just all identical.
Described color layers at least surface has color, this color can be material itself have color (such as color layers be plant blade, there is the metal etc. of natural gloss), also can be adopt coating, contaminate or the technique such as printing carry out painted after result; Described color not only comprises colour, can also comprise white (when the color of anti-counterfeiting characteristic layer itself is not for white), the color etc. of metal.
Wherein, when a first area 13 only penetrates anti-counterfeiting characteristic layer 11, when another first area 13 penetrates anti-counterfeiting characteristic layer 11 and first color layers 121, the xsect of described anti-counterfeit structure as shown in Figure 2, first area 13 is equivalent to " punch " on anti-counterfeiting characteristic layer 11, if more shallow, only penetrates anti-counterfeiting characteristic layer 11, what then expose is the color of first color layers 121, as being positioned at the first area 13 on the right in Fig. 2; If deep, penetrate anti-counterfeiting characteristic layer 11 and first color layers 121, then can expose the color of second color layers 122, as being positioned at the first area 13 on the left side in Fig. 2.If first area 13 has penetrated N number of color layers (color layers 122 as in Fig. 2), then can present the color of the object of the bottom surface covering described N number of color layers.
Wherein, can be, but not limited to make first area 13 penetrate described anti-counterfeiting characteristic layer 11 and color layers 12 by the mode such as hollow out, engraving; When the degree of depth of hollow out or engraving is random, the first area formed will penetrate M color layers at random.Certainly, also may comprise hollow out in described anti-counterfeiting characteristic layer 11 or carving depth crosses the shallow region not penetrating anti-counterfeiting characteristic layer 11, also can leave a trace in these regions on anti-counterfeiting characteristic layer, but can not present the color of color layers.
Visible, except the feature (one or more in the feature such as such as size, quantity, position, content, anglec of rotation) that the present embodiment makes anti-counterfeiting information have except itself, also add random color character; The anti-counterfeiting information of different preventing pesudo-structure due to the degree of depth be all random, the coloured anti-counterfeiting information of the band therefore in different preventing pesudo-structure will substantially cannot be identical.Such design not only increases aesthetic feeling and identification, the more important thing is the random degree and personalization level that can strengthen anti-counterfeiting information on each anti-counterfeit structure, by each anti-counterfeit structure and product one_to_one corresponding false proof to carry out, greatly can increase the difficulty of imitation.
Anti-counterfeit structure in the present embodiment can be, but not limited to as antifalsification label, can also be anti-counterfeit package box/bottle, Antiforge card etc.
Alternatively, described anti-counterfeiting information comprises following any one or its combination in any:
Quick Response Code, character, figure.
When anti-counterfeiting information is Quick Response Code, the region namely on first area and anti-counterfeiting characteristic layer beyond first area forms anti-counterfeiting information jointly.
Quick Response Code is generally the figure of chequered with black and white (or the depth is alternate), in this optional manner, when anti-counterfeiting information comprises Quick Response Code, first area can as black (or dark) part in Quick Response Code, now alternate with first area on anti-counterfeiting characteristic layer region is as white (or light color) part in Quick Response Code, namely region that is transparent or that penetrate anti-counterfeiting characteristic layer forms black (or dark) part in Quick Response Code, and this is the implementation of " negative "; Certainly, also can first area as white (or the light color) part in Quick Response Code, now alternate with first area on anti-counterfeiting characteristic layer, need spray black (or dark) ink (or it is painted to adopt alternate manner to realize) as the region of black (or dark) part in Quick Response Code, this is the implementation of " positive image ".
In this optional manner, the penetration depth of the different piece in same Quick Response Code can be different, will have concave-convex sense by the first area Quick Response Code formed alternate with all the other regions; Such Quick Response Code is no longer a planar graph, but has three-dimensional structure, is also more beneficial to false proof.
In this optional manner, the part penetrated in described Quick Response Code can present random color, and the color that the Quick Response Code in such different preventing pesudo-structure presents is incited somebody to action substantially can not be identical; Such as may occur following situation: in an anti-counterfeit structure, the first area of the first half of Quick Response Code presents blueness, and the first area of the latter half presents redness; In another anti-counterfeit structure, the first area being positioned at the Quick Response Code upper left corner presents blueness, and the first area of Quick Response Code remainder presents redness.By random color and Quick Response Code combine carry out false proof, false proof will more have randomness and personalization is carried out than the information of only being carried by Quick Response Code itself, even if imitator can copy out Quick Response Code like this, also accurately the Quick Response Code of each anti-counterfeit structure cannot to be penetrated or the random color at transparent place accurately copys out, to add the difficulty of imitation.
In this optional manner, described figure can be various shape, such as circle, rectangle, triangle, irregularly shaped etc.; Anti-counterfeiting characteristic layer in an anti-counterfeit structure can there is one or more figure, also can there is no figure.
In this optional manner, the anti-counterfeiting characteristic layer in an anti-counterfeit structure can there is one or more character, also can there is no character; Described character can comprise Chinese character, other country's word, letter, numeral, symbol etc.
The character that this optional manner is formed also has concave-convex sense, and the penetration depth of the different piece in same character can be different; The part not penetrating anti-counterfeiting characteristic layer is the region of " convex ", and the part penetrating anti-counterfeiting characteristic layer is the region of " recessed ".Can be that the region of " recessed " forms character (region that a such as hollow character occupies itself), also can be that the region of " convex " forms character (part beyond the region such as occupied by character except for the outer beyond frame all hollow out).
When an anti-counterfeit structure having multiple character, multiple character can be arranged in one or multirow or be arranged in one or multiple row, also can have random position.Multiple characters on an anti-counterfeit structure can be possess the word of definite meaning or phrase (such as can select publicity corporate culture or significant phrase), also can mutually between completely without contacting; Character on each anti-counterfeit structure is usually not identical or not identical at least partly; But also can be designed as all identical.
The anglec of rotation of each character is the random value (being equivalent to non rotating when being 0 or 360 degree) between 0 ~ 360 degree; On an anti-counterfeit structure, the anglec of rotation of each character can all identical, part is identical or not identical.In addition, each character on an anti-counterfeit structure differs, and to establish a capital be complete, than if any character can only have part, but in an anti-counterfeit structure, at least comprise a complete character.
Can be different at least partly in the parameter such as quantity, content, the anglec of rotation, position of the character in each anti-counterfeit structure, also can all identical (other anti-counterfeiting information now in different preventing pesudo-structure needs difference, or the color of color layers and/or to stack order different, to ensure that the anti-counterfeiting information in different anti-counterfeit structures can not be identical).
When anti-counterfeit structure comprises figure/character, when also comprising Quick Response Code, the information in Quick Response Code can be generate according to described figure/character (can be only limited to complete character), also can have nothing to do with figure/character.Quick Response Code in different preventing pesudo-structure can be different.
Alternatively, below any one or appoint several be random:
The color of described anti-counterfeiting information, described color layers; Described color layers stack order;
Such as, when there being two color layers, what color is each color layers be is random choose; For another example, when having two color layers and the color of each color layers is determined all, above which color layers is placed on, (namely adjacent with anti-counterfeiting characteristic layer) is random.
Described anti-counterfeiting information comprise at random following any one or appoint several situation:
The position of described anti-counterfeiting information on described anti-counterfeiting characteristic layer is random;
The profile of described anti-counterfeiting information is random;
The content of described anti-counterfeiting information is random;
In described anti-counterfeiting information, the angle of each content is random at least partly.
Generally speaking, described anti-counterfeiting information just refers to that the anti-counterfeiting information in different preventing pesudo-structure also has ga s safety degree when not presenting color at random; Even if like this color layers color and stack order and be that regular, each anti-counterfeit structure is identical and the penetration depth of anti-counterfeiting information is identical, because anti-counterfeiting information is random, anti-counterfeiting information in different preventing pesudo-structure is inherently different, therefore can be more personalized after adding the color presented, identification is higher.
Alternatively, in each described color layers, part or all of color has random penetration region.That enumerates above variously penetrates mode or other any mode that penetrates all can be used for forming described penetration region.Described penetration region also can change transparent region into, and the effect reached also is the same.
Wherein, the position and/or the profile that refer to penetration region are at random random.Described first area in a described color layers and described penetration region do not overlap or partially overlap.
Uppermost color layers can be made like this to expose the color of color layers below; Such as red blue yellow three color layers be superimposed, as shown in Fig. 3 (a), red color layer 21 is topmost, and cyan coloring layer 22 is in centre, and buffy layer 23 is in bottom.As shown in Fig. 3 (b), after superposition, when there is penetration region 24 in red color layer 21, this part penetration region 24 can expose blueness, if when also having penetration region (region namely in figure in dashed rectangle) in cyan coloring layer 22 and partially overlap with the penetration region of red color layer, intersection 25 can expose yellow.Uppermost color layers (first color layers) can be made like this to present two or more color of stochastic distribution.Now, if the relevant position being positioned at the anti-counterfeiting characteristic layer above penetration region 24 has first area, though then engraving or hollow out time this first area only penetrated anti-counterfeiting characteristic layer, the color of what this first area presented is cyan coloring layer 22; Similarly, if the relevant position being positioned at the anti-counterfeiting characteristic layer above penetration region 25 has the first area only having penetrated anti-counterfeiting characteristic layer, the color of what this first area presented is buffy layer 23.
Alternatively, described anti-counterfeit structure can also comprise:
Hyaline membrane, is positioned at each described color layers surface.
Described hyaline membrane can be, but not limited to as PET film, for the protection of coloured part.If form first area by the mode such as laser engraving, hollow out, then may cause damage to color, and transparent plastic mulching can be prevented or alleviate this infringement on color surface.
