Holographic false proof printing process
Technical field the present invention relates to printing technology, particularly relates to holographic false proof printing process.
Background technology is along with the improve day by day of people's living standard, and people require also more and more higher to the decoration of packaging, especially tobacco bale dress and wine packaging.The expressive ability of hologram is that common picture and text can not be compared, existing high-grade packaging, especially high-grade cigarette, wine packaging, all extensively adopt hologram is organically printed on common picture and text together with and realize primary holographic false proof.The combination of hologram and common picture and text, in prior art, what generally adopt has two kinds.Be a hot stamping for comparatively getting up early, adopt hot stamping technique that hologram location is transferred on stock and organically combine with common picture and text; Another kind is composite transferring technology, and the film that has a hologram by mold pressing and the paperboard that is printed with common picture and text carry out compoundly peeling off again, and the hologram on film is transferred in paperboard.All there is the deficiency that working (machining) efficiency is low in these two kinds of technology, the more important thing is, in these two kinds of technology, due to the restriction of technique itself, unit holographic false proof information target area can inevitably do greatlyr, and arranges and locate fixing, be easy to be imitated, can not reach real antifalse effect.
Summary of the invention the technical problem to be solved in the present invention is to avoid above-mentioned the deficiencies in the prior art part and proposes a kind of holographic false proof printing process, adopts the method working (machining) efficiency high, can stop holographic false proof information target imitated, realizes real antifalse effect.
The present invention solve the technical problem can be by realizing by the following technical solutions:
Propose a kind of holographic false proof printing process, comprise the steps:
A. make hologram version, this hologram version typesetting has multiple identical holographic false proof marks, in each holographic false proof mark, comprises at least one anti-counterfeiting information;
B. utilize the hologram version in steps A to make holographic laser film;
C. the holographic laser film in step B is ground into fractionlet, and mixes in aqueous clear coating, the fineness of described hologram version can ensure also to preserve in each holographic laser film fractionlet at least one complete holographic false proof mark;
D. the aqueous clear coating that is mixed with holographic laser film fractionlet in step C is applied on stock;
E. the common picture and text of registration printing on the stock through after step D.
In described step D, coating is mixed with the aqueous clear coating of holographic laser film fractionlet, is local positioning coating or full version coating.
In each described holographic false proof mark, comprise two or more anti-counterfeiting information.
The base material of described holographic laser film is PET film (poly terephthalic acid second two fat), PP film (polypropylene) or OPP film (oriented polypropylene (OPP)).
Described stock is art paper, art post paperboard, gold and silver paperboard or radium-shine paperboard.
Compared with the existing technology, the technique effect of holographic false proof printing process of the present invention is: 1. holographic laser film be ground into fractionlet and mix in aqueous clear coating, be coated directly onto on stock, working (machining) efficiency is more much higher than holographic film and stock composite transferring; 2. holographic laser film is ground into fractionlet, in each fractionlet, also preserve at least one complete holographic false proof mark, holographic false proof mark on fractionlet just can be identified by amplifying under recognition device, because holographic false proof sample body is quite small, be difficult for being imitated, and it is upper that countless multiple fractionlets are coated on stock (packing box), plays real antifalse effect; 3. in each holographic false proof mark, comprise two or more anti-counterfeiting information, the size of every kind of information, arrange position and shared area ratio in holographic false proof mark are all to determine when making holographic version, and need to amplify and could identify, unless known the data message of original holographic version, counterfeit reduction absolutely not may.
detailed description of the invention
Holographic false proof printing process of the present invention, comprises the steps:
A. make hologram version, this hologram version typesetting has multiple identical holographic false proof marks, in each holographic false proof mark, comprises at least one anti-counterfeiting information;
B. utilize the hologram version in steps A to make holographic laser film;
C. the holographic laser film in step B is ground into fractionlet, and mixes in aqueous clear coating, the fineness of described hologram version can ensure also to preserve in each holographic laser film fractionlet at least one complete holographic false proof mark;
D. the aqueous clear coating that is mixed with holographic laser film fractionlet in step C is applied on stock;
E. the common picture and text of registration printing on the stock through after step D.
In described step D, coating is mixed with the aqueous clear coating of holographic laser film fractionlet, is local positioning coating or full version coating.Under the condition of the license of technology, the sequencing of described step D and step e also can be exchanged, and first prints common picture and text and is then coated with the aqueous clear coating that is mixed with holographic laser film fractionlet.
In the present invention, the base material of described holographic laser film is PET film (poly terephthalic acid second two fat), PP film (polypropylene) or OPP film (oriented polypropylene (OPP)), certainly, also can also adopt other plastic sheeting.Described stock is art paper, art post paperboard, gold and silver paperboard or radium-shine paperboard, can be also other printable fabrics.Described aqueous clear coating can be varnish or water-base resin etc.
Counterfeit in order more thoroughly to stop better, in each described holographic false proof mark, comprise two or more anti-counterfeiting information, these anti-counterfeiting information can be word or figure and combination thereof, for example lot number of the trading company of the trading company of packages printing producer, manufacturer and mark, product etc.Be packaged as example with cigarette, the cigarette-brand of Hongta board cigarette prints business by power group to be printed, and each holographic false proof target anti-counterfeiting information forms by three kinds: the word of " Hongta ", " power group prints business ", and the logotype of Hongta; These three kinds of anti-counterfeiting information in the time making holographic version according to certain mode typesetting, and the space of a whole page ratio accounting in each comfortable holographic false proof mark be respectively 30%, 30% and 40%(certain, if words more accurately, can be set to ratio more complicated and that be difficult for cracking), each holographic film fractionlet is at least recorded the anti-counterfeiting information of a group complete " Hongta ", the word of " power group prints business " and the logotype of Hongta, needs to amplify just can be identified.In the time that counterfeiter's wish is imitated, although likely accomplish also to have three kinds of anti-counterfeiting information, in the time there is no 30%, 30% and 40% these plate-making data, can not realize space of a whole page ratio accomplishes consistent with holographic false proof mark, that is to say, in this case, imitated is impossible.In the time that anti-counterfeiting information design is more, just more can not be imitated, and printing factory can be according to client's requirement, periodic replacement hologram version, then secretly reports plate-making data to client, realizes client to real false proof demand.
Above content is in conjunction with concrete optimal technical scheme further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
