Description
Technical field
The present invention relates to anti-fake mark, false proof signature field, be specifically related to the manufacturing of OVD and digital anti-fake mark.
Background technology
Optical Variable Imaging (OVD) is a kind of optical anti-counterfeiting sign of precision, it has used complicated laser diffraction technology, when ray cast can change diffracting effect into during to fine and closely woven striped top layer, so just can produce the degree of depth, perspective and multi-level reflecting effect in the design, have and be easy to discern, be easy to the characteristics remembering, be easy to describe, it is shown one's talent in numerous anti-counterfeiting technologies.Optical Variable Imaging has the feature of anaclasis, wherein variable light incident energy causes that image changes, under different viewing angles, demonstrate the distinct image contrast, even under diffused light or dim illumination condition, its structure also can be recognized, therefore a kind of method of simple identification authenticity of products is provided to the consumer, in order to improve safe coefficient, also add special security element, as lens, contrast effect and hiding feature, when can only or amplifying under certain viewing angle, these special security element just come as can be seen.
General anti-counterfeiting stamping foil, because the restriction of plate-making technology, its false proof lower grade, antifalse effect is undesirable, and the visual signature of optical anti-counterfeiting sign derives from the plate-making technology of mother matrix, the advance of plate-making technology and exclusivity directly influence false proof degree.At present both at home and abroad the mother matrix generation technique that generally adopts is mainly " two-dimensional/three-dimensional " and " digital dot matrix " two kinds, but above two kinds of still effective abroad mother matrix technology are widely used at home, and its false proof reliability is very low.
In order to improve the anti-counterfeiting performance of optical anti-counterfeiting sign, some enterprises have adopted the whole bag of tricks to adhere to various information on common anti-counterfeiting stamping foil, for example on anti-counterfeiting stamping foil, adhere to numerical code, thumbnail image, two-dimension code etc. by the method for printing or laser marking, but following several method is generally taked in the place that the beginning comes with some shortcomings in the prior art:
A, two-dimension code figure and the false proof manufacturing technology of traditional printing combine, and avoid two-dimension code figure directly to be xeroxed, take pictures, such as adopting stealthy printing or the like;
B, two-dimension code (sign indicating number) figure itself is done special processing (as encrypting, compound etc.), allow others' recognition software can't identification code figure, the 2nd, can in these yards figure, enroll special information, to make the usefulness of false proof verification;
C, the two-dimension code of special processing is combined with traditional anti-counterfeiting technology, set up merchandising database, the information that comprises in the two-dimension code matches, and sets up inquiry response mechanism.
For example the patent No. is 02270995.9 Chinese utility model patent, a kind of holography digital two-dimension code anti-counterfeit sign of reprinting books in a reduce format is disclosed, this anti-counterfeiting mark is successively by numerical code and PDF417 two-dimension code anti-counterfeit layer, chromatic printing machine is moulded the false proof composite bed of seal micro, the pressure-sensitive adhesive layer stack is composited, and the local location on numerical code and PDF417 two-dimension code anti-counterfeit layer is manufactured with laser hologram image, this anti-counterfeiting mark adopts the partial holography technology, mould the seal shrink technology, numerical code technology and the integrated application of PDF417 planar bar code technology, form multiple anti-fake, comprise on this anti-counterfeiting mark that numerical code and PDF417 two-dimension code all are to realize adhering to by printing, abrasion resistance is relatively poor, and more information pattern is combined with each other, show slightly numerous and diverse, moreover, the production of this anti-counterfeiting mark relates to kinds of processes, comparatively complicated, its laser holography that adopts has been lost antiforge function basically, can increase production cost, is unfavorable for promoting the use of on general goods.
The patent No. is 201020102478.2,201010101642.2,201020115905.0,200710173477.X, 200920060588.4 several Chinese patents disclose different anti-counterfeiting technology that relates to two-dimension code and sign, but above-mentioned patent has a common feature to be exactly: computing machine generates two-dimension code and other information, read decoding apparatus and obtain this 2 D code information, transform the back and two-dimension code is marked in product surface (card by high energy laser beam by laser coding device, the surface of glass etc.), the scope of application of this mode is less, it is hard to be used for the surface, on the on-deformable product, and for a lot of products papery packing for example, plastics packed product then can't be implemented.
Summary of the invention
In order to solve the deficiency that exists in the background technology, the invention provides a kind of method of making the composite multifunction anti-counterfeiting mark, purpose is to solve the two-dimension code that adheres on the anti-counterfeiting mark in the prior art, thumbnail image is fragile be cannot say for sure to deposit and shortcoming that false proof grade is not high, produce Optical Variable Imaging and two-dimension code, combinations such as thumbnail image, can use carrier material extensive, anti-counterfeiting mark with higher false proof grade, this production method is applied widely, technology is understood enforcement easily, and anti-counterfeiting mark enterprise can reduce the cost of printing enterprise and wrapping enterprise after using greatly.
For achieving the above object, the present invention has adopted following technological means, and this production method may further comprise the steps:
A, as required produces and reserves the big roll-leaf of OVD that laser ablation district and laser ablation district background have security element;
B, the big roll-leaf that step a is produced carry out defective product and detect and reject or mark;
C, the OVD paper tinsel that detects is cut, be processed into and be fit to coiling of thermoprint;
D, utilize laser ablation to fall the aluminium coated in the laser ablation district background patterns, keep basement membrane, combined by white space that etches away and the material of aluminizing that retains, to form new security pattern;
E, rouleau paper tinsel film utilize locating thermoprint equipment to carry out thermoprint on corresponding product;
Wherein, comprise following main points in the process of the described etching two-dimension code of steps d:
