A kind of integrated laser anti-counterfeit package and preparation method thereof
Technical field
The present invention relates to the anti-counterfeit package field, a kind of integrated laser anti-counterfeit package and preparation method thereof of saying so more specifically.
Technical background
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 tamperer 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 customer 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 tamperer 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
Technical matters to be solved by this invention is the defective that overcomes prior art, and integrated laser anti-counterfeit package of a kind of better antifalse effect and preparation method thereof is provided.In the method for making of the present invention, the variable of laser picture and text 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.
The present invention is achieved through the following technical solutions above-mentioned purpose.
A kind of integrated laser anti-counterfeit package, cover is printed on the laser anti-counterfeit label on the external packing carrier of product, it is characterized in that described laser anti-counterfeit label from bottom to top comprises resistance to alkalis ink lay, metal level and transparent photosensitive material layer at least, described resistance to alkalis ink lay, metal level and transparent photosensitive material layer have identical and overlapping hollow picture and text.
Further also be coated with layer of transparent separated type material layer on the described transparent photosensitive material layer.
Its preparation method may further comprise the steps:
S1 is printing figure message on release base stock;
S2 is made into hollow picture and text by the mode that repeats alkali cleaning and ultraviolet exposure with the printing figure message on the release base stock;
S3 will print and the release base stock of pierced process cuts into a plurality of unit label printing body;
S4 positions transfer printing on the packaging with unit label printing body, forms the integrated laser anti-counterfeit package with packing.
The method for making of the integrated packing of variable graphic that the present invention is designed with laser holographic effect, be to realize false proof by on certain zone of external packing, forming hollow graphic units with laser holographic effect and diversity, this technical guarantee the uniqueness of picture and text, and picture and text self also have antifalse effect, and the imitator can't produce by common technology to have laser holographic effect and can change picture and text by ccasual.Adopt in the anti-counterfeit package of this technology even need not picture and text are covered, the customer directly can be by the true and false of naked eyes diagnosis unit picture and text, and picture and text can also have the double anti-forge effect further by the phone and the network inquiry true and false.With respect to prior art, integrated laser anti-counterfeit package 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 present invention, the customer 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.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structure cutaway view of A part among Fig. 1.
The specific embodiment
The present invention is described further below in conjunction with accompanying drawing.
A kind of integrated laser anti-counterfeit package as shown in Figure 1, cover is printed on laser anti-counterfeit label 2 on the external packing carrier 1 of product.In conjunction with shown in Figure 2, described chromatography package carrier 1 laser anti-counterfeit label 2 outside from bottom to top comprises resistance to alkalis ink lay 21, metal level 22, transparent photosensitive material layer 23 and transparent separated type material layer 24, described alkaline ink lay 21, metal level 22, transparent photosensitive material layer 23 and transparent separated type material layer 24 have identical and overlapping hollow picture and text, and openwork part is 3.
Wherein alkaline ink lay 21 is to be used to form various different picture and text, can in time change anti-counterfeiting mark, and is perhaps that anti-counterfeiting mark is complicated, causes the tamperer can't time update, perhaps can't be by the follow-up of constantly making a plate of the method for laser forme on the cost.Metal level 22 and transparent photosensitive material layer 23 are used for laser compacting back and form the laser effect.The general aluminium laminations that adopt of metal level 22, transparent photosensitive material layer 23 can be carried out monochrome and be mixed look, forms with metallic aluminium to have the laser effect of metal-like, as golden, bronze-colored or the like.The effect of this metal-like has better false proof and aesthetic effect with respect to the silvery white that adopts general technology to accomplish.Transparent separated type material layer 24 is used for chromatography, in package carrier 1 printing, on packing box, leave blank space, to be printed on blank space through the form of the anti-dummy unit after printing, hollow out and the cutting by transfer printing, and remove release base stock and promptly form the integrated laser anti-counterfeit package.
The preparation method of above-mentioned integrated laser anti-counterfeit package may further comprise the steps:
S1 is printing figure message on release base stock, specifically comprises:
S1.1 prints one deck separated type material layer on the interim matrix of one deck;
S1.2 coats the layer of transparent photosensitive material layer on the separated type material layer, can select that transparent photosensitive material layer is carried out monochrome and mix look, and transparent photosensitive material layer is carried out the laser compacting, forms the carrier of the laser holographic effect with monochromatic color;
S1.3 plates one deck aluminium lamination on the laser press face of transparent photosensitive material layer;
S1.4 adopts alkaline-resisting printing ink chromatography or digital printed required picture and text on aluminium lamination, form the resistance to alkalis ink lay with picture and text.
S2 is made into hollow picture and text by the mode that repeats alkali cleaning and ultraviolet exposure with the printing figure message on the release base stock, specifically comprises:
S2.1 is with the aluminium lamination that is not covered by the resistance to alkalis ink lay in the sodium hydroxide solution flush away picture and text;
S2.2 carries out ultraviolet exposure in interim basal body coating layer one side, makes in the picture and text and is not degraded into alkali-soluble by the transparent photosensitive material layer of resistance to alkalis ink lay and aluminium lamination covering;
S2.3 uses in the sodium hydroxide solution flush away picture and text once more not by the transparent photochromics of resistance to alkalis ink lay and aluminium lamination covering, formation has overlapping hollow picture and text on interim matrix transparent photosensitive material layer, aluminium lamination and resistance to alkalis ink lay.
S3 will print and the release base stock of pierced process cuts into a plurality of unit label printing body;
S4 positions transfer printing on the packaging with unit label printing body, forms the integrated laser anti-counterfeit package with packing.
The present invention by the form of high density plate-making, has made the laser anti-counterfeit labeling of a plurality of different picture and text of justifying, and then has cut into a plurality of unit label printing body earlier, just is transferred on the external packing carrier at last.Can reduce printing cost greatly by the unified mode of printing, and the present invention can directly realize printing by the mode of printing, need not plate-making, cost reduces greatly, and can flexibly customizing labeling content, improves anti-counterfeit capability greatly.
