Background technology
Laser holography is a kind of use anti-counterfeiting technology widely, and this technology reaches false proof purpose by make the image with laser hologram in the backguy of label, hard box or blister-pack or blister-pack.This carriers such as label, packing or packing backguy that have laser hologram image on it can be referred to as laser anti-fake figure mark.
Existing laser anti-fake figure mark comes with some shortcomings in practice: conventional laser hologram similarly is to form by the mold pressing on polyester film of holographic nickel version, the format of the laser image of the laser anti-fake figure mark that this mode is made or pattern are very limited, can only be used for the identical fixed version pattern of printing of repetition.If the adulterator has obtained the pattern of these laser images, just can copy out very soon.Caused traditional laser anti-fake figure mark almost to lose anti-counterfeit capability thus.
It is false proof that common code anti-fake technology adopts the form of different number and figure to carry out, and as random digit, the consumer authenticates by input random digit after dialing the checking phone.But random digit self is without any anti-counterfeiting technology in this technology, so generally need to adopt the form that covers to cover random digit.This technology is complex procedures not only, and the form that covers almost do not have anti-counterfeit capability, and main anti-counterfeit capability is the telephone service system, but the technology content of telephone service system now is not high yet, and the adulterator has the ability to duplicate or copy fully.
Therefore the antifalse effect that improves the conventional laser anti-counterfeiting mark is technical issues that need to address.
Summary of the invention
The technical problem that the present invention solves provides texture label of a kind of laser anti-counterfeit with better antifalse effect and preparation method thereof.In the preparation method of the present invention, the variable of laser data makes the laser hologram image on the laser anti-fake figure mark have nothing in common with each other, and has uniqueness, perhaps is also referred to as diversity, thereby has more excellent antifalse effect.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
The texture label of laser anti-counterfeit of the present invention is to realize false proofly by form hollow graphic units with laser holographic effect, diversity and unrepeatable textural characteristics on carrier, and its preparation method specifically may further comprise the steps:
Step 1 is made the carrier that single face has laser holographic effect, and carrier from bottom to top comprises texture basic unit, metal level and transparent photosensitive material layer at least, and the one side of described transparent photosensitive material layer and metal level bonding is the laser press face;
Step 2 adopts digital printing or digital printed mode to print or printing transparent printing ink or colored ink on the same one side of transparent photosensitive material layer, and the picture and text unit of printing or printing has diversity;
Step 3 is carried out the high intensity ultraviolet line exposing to printing or printing surface, makes the transparent photosensitive layer material that is not covered by transparent ink resolve into alkali-soluble;
Step 4, the transparent photosensitive material layer and the metal level under it that adopt the alkaline solution flush away not covered by transparent ink or colored ink make openwork part not have a laser holographic effect;
Step 5 is that a unit cuts carrier by each graphic units, and each anti-dummy unit of cutting back includes only the hollow graphic units of a laser holographic effect and diversity;
Step 6, with false proof unit application in anti-counterfeit package.
The variable graphic anti-counterfeiting label producing method that the present invention is designed with laser holographic effect, be to realize false proof by in texture basic unit, forming hollow graphic units with laser holographic effect and diversity, this technology has not only guaranteed the uniqueness of graphic units, and graphic units and texture self also have antifalse effect, the imitator can't produce by common technology has laser holographic effect and variation picture and text that can be at random, also can't copy identical texture.Adopt in the anti-counterfeit package of this technology even need not graphic units is covered, the consumer directly can be by the true and false of naked eyes recognition unit picture and text, the texture anti-fake aspect also can have the double anti-forge effect further by the true and false of phone and network inquiry picture and text.With respect to prior art, texture label of the laser anti-counterfeit of the inventive method manufacturing and preparation method thereof has following beneficial effect: reduced the step that picture and text are covered in the production process of the texture label of laser anti-counterfeit of the present invention, the consumer distinguishes with naked eyes whether different picture and text have laser effect and can judge the true and false, except that the inventive method, the counterfeiter who makes variable graphic need make countless mother matrixs and print, cost ten/height does not meet the requirement of counterfeit industry to cost.The consumer can also further examine texture by other means, and data texturing storehouse difficulty of reproduction is big, and can change at any time, has higher security.
The specific embodiment
The present invention is described further below in conjunction with accompanying drawing.
The texture tag unit of two kinds of laser anti-counterfeits as shown in Figure 1, by in texture basic unit 1, form the hollow graphic units 2 with laser holographic effect and diversity realize false proof, among the figure about the graphic units 2 of two texture tag units be different fully and have the laser effect.Make the picture and text that the printer air brushing goes out to have the laser effect that pass through that the manufacturer of label can be random, having overcome laser printing in the past can only be the defective of repeating print after the plate-making, therefore graphic units 2 self also has antifalse effect, the imitator can't produce the variable graphic with laser holographic effect by common technology, cost does not allow in other words, thereby reaches false proof purpose.Certain texture of the present invention basic unit 1 has antifalse effect equally, by the various combination of texture, can reach the not repeated of texture and can not copying property.The identification more complicated of this method for anti-counterfeit needs the consumer to be dealt on the network data base with texture scanning or after taking a picture and compares, but has higher security with respect to common code anti-fake technology.
The concrete structure of the texture tag unit of above-mentioned laser anti-counterfeit has two kinds of structures as shown in Figures 2 and 3.First kind of example structure is from bottom to top to comprise texture basic unit 1, metal level 21, transparent release material for transfer layer 22, transparent photosensitive material layer 23 and ink lay 24 at least, and wherein metal level 21, transparent release material for transfer layer 22, transparent photosensitive material layer 23 have identical and overlapping hollow picture and text 2 with ink lay 24.Second kind of example structure as shown in Figure 3, except above-mentioned each layer structure, also the opposite side in texture basic unit 1 is provided with pressure sensitive adhesive 11 and protective layer 12 successively.The unit label that this structure fabrication the is good protective layer of only need tearing just can directly be pasted antifalsification label on product, and is easy to use.
The structure of above-mentioned two embodiment can also further be carried out monochrome to transparent release material for transfer layer 22 and be mixed look, formation has the carrier of the laser holographic effect of monochromatic color, and can form color after color and metal level 21 mutual superposition that are plated to metallic aluminium with metal sense, as golden, coppery or the like.Described ink lay 24 is to adopt ink-jet or digital printed mode to form, so the style of color and picture and text can customize and change at any time.As the picture and text of multiple color can be arranged among Fig. 1, digital picture and text can adopt different colors with alphabetical picture and text.
The preparation method of the texture label of above-mentioned laser anti-counterfeit as shown in Figure 4, specifically may further comprise the steps:
Step 1, make the carrier that single face has laser holographic effect, carrier from bottom to top comprises texture basic unit 1, metal level 21, transparent release material for transfer layer 22 and transparent photosensitive material layer 23, and described transparent release material for transfer layer 22 is the laser press face with the one side of metal level 21 bondings;
Step 2, the employing number is printed or digital printed mode is printed on the same one side of transparent photosensitive material layer 23 or print monochrome or bright printing ink of polychrome or colored ink, make the picture and text unit of printing or printing have diversity, form picture and text unit with particular color or color combination; And can adopt linear print or block the printing at different application purposes;
Step 3 is carried out the high intensity ultraviolet line exposing to printing or printing surface, makes the transparent photosensitive layer material that is not covered by transparent ink resolve into alkali-soluble;
Step 4, the transparent photosensitive material layer 23 and transparent release material for transfer layer 22 and the metal level 21 under it that adopt the sodium hydroxide solution flush away not covered by transparent ink or colored ink make openwork part not have a laser holographic effect;
Step 5 is that a unit cuts carrier by each graphic units, and each anti-dummy unit of cutting back includes only the hollow graphic units of a laser holographic effect and diversity;
Step 6, with false proof unit application in anti-counterfeit package.
The manufacturing process of carrier may further comprise the steps as shown in Figure 5 in the above-mentioned steps one:
To on a transfer vector, apply and advance the monochromatic transparent release material for transfer layer of mixing look;
Transparent release material for transfer layer is carried out the laser compacting;
On the laser press face of transparent release material for transfer layer, be coated with metal level, be made into reverse laser holographic effect material;
Carry out reverse laser holographic effect material and texture basic unit compound;
Remove transfer vector and form the carrier that from bottom to top comprises texture basic unit, metal level and transparent release material for transfer layer at least;
On transparent release material for transfer layer, apply the layer of transparent photosensitive material layer, form the carrier of laser holographic effect with monochromatic color.
The preparation process of described texture basic unit be with immiscible texture materials with make sheet after base material mixes.
The imitator is not as adopting said method, can't pass through the above-mentioned Antiforge of existing techniques in realizing, mainly contain the technology limitation of two aspects, the first can't be printed the picture and text of variation by the mode of fixed version printing laser effect, each variation all will be made a plate again, and the mode of picture and text imitator's the fraud cost that makes especially remains high at random.It two is to print the printing technology of picture and text at random, as digital printing technology etc., and the printing ink that can only adopt black or redness etc. very to limit to, the color variation all can't realize, let alone the laser effect.
The present invention realizes false proofly by form the hollow graphic units with laser holographic effect and diversity on carrier, i.e. the present invention has realized that laser variable data is false proof.
