Description
Technical field
The invention belongs to field of anti-counterfeit technology, be specifically related to a kind of method of laser film being processed Quick Response Code.
Background technology
Laser marking code range of application is more and more wider, and what it had can not wiping and be subject to the consistent accreditation of businessman.The advantage of Laser Jet: without ink, impression is clear, erase lastingly, not easily, and be a kind of contactless mode of printing, Surface Quality requires low, and environmental protection.And the application of laser film anti-counterfeiting mark is also more and more wider, because itself not only having changeable anti-counterfeiting information, and its outward appearance has paper and identifies the laser brightness effect that do not have and the favor that is subject to vast businessman.Equally, the two-dimension code anti-counterfeit mode of application at present becomes more and more popular especially, and the application of Quick Response Code not only solves the few shortcoming of one-dimension code information memory capacity, also solves the problem that inquiry mode is single.That is, Quick Response Code not only can the relevant information of storing commodity, also can store the part relevant information of enterprise, identification method is simple and fast also, only by mobile phone photograph, just need can demonstrate the relevant information of commodity, this is also the most frequently used counterfeit protection measures of current consumer.
In the development of current anti-counterfeiting mark industry, the requirement of businessman to mark is more and more higher, not only requires that mark has variable irreplaceable antifalse effect, also requires the aesthetics identified.But because of the limitation of its laser film, (can not print the shortcoming of Quick Response Code in the above), causes laser film and Quick Response Code to carry out connected applications.Although have thermoprint Quick Response Code on paper anti-counterfeiting mark at present, because its Quick Response Code itself has variable uniqueness, therefore cause the Quick Response Code of thermoprint to be changeless, lost the security feature that Quick Response Code is variable.Although also have businessman's spray printing Quick Response Code on laser film at present, but because of the reason of its ink poor adhesive force on laser film, the Quick Response Code of spray printing is caused very easily to be rubbed off in following process process, cause the rejection rate of mark high, customer response weak effects etc., therefore do not meet Production requirement.
The patent No. is that 102184676B mainly describes a kind of method manufacturing composite multifunctional anti-counterfeiting mark, object is to solve fragile being difficult to ensure of the Quick Response Code, the thumbnail image that anti-counterfeiting mark adhere in prior art and deposits and shortcoming that false proof grade is not high, have employed following steps: as required, produce reserved laser ablation district and laser ablation district background has the large roll-leaf of OVD of security element; A, to step a produce large roll-leaf carry out defective product detection and reject or mark; B, the OVD paper tinsel detected to be cut, be processed into coiling of applicable thermoprint; C, the aluminium coated in laser ablation district background patterns is utilized laser incising eating away, retains basement membrane, by the white space etched away and the material of aluminizing retained combined, to form new security pattern; D, little roll-leaf film utilize locating thermoprint equipment to carry out thermoprint on corresponding product.This patent mainly adopts OVD base material, then carries out laser ablation, not applicable for laser film conventional at present.And be only carry out etching and thermoprint on its surface, mainly in order to prevent the pattern of the OVD substrate surface shortcoming that degree of reservation is not high in follow-up processing.
The advantage of Laser Jet: without ink, impression is clear, erase lastingly, not easily, and be a kind of contactless mode of printing, Surface Quality requires low, and environmental protection.
Be that starting material adopt normal procedure to carry out Quick Response Code stamp on laser marking machine with laser film, stamp is respond well, but mobile phone cannot be distinguished scanning and carries out Antiforge inquiry.Find, because its laser film is the false proof base material with laser effect, to there is certain reflecting effect through experimental summary, therefore cause mobile phone knowledge and magnanimity of cannot taking pictures to carry out Antiforge inquiry.If adopt normal digital ink in laser film printing on substrates Quick Response Code mark, but because of the poor adhesive force of its ink, in follow-up processing with in using, very easily cause the friction of mark with damaged etc.And the identification pattern of laser marking machine stamp is not easily wiped, so major advantage is directly being burnt on base material, therefore can not be wiped free of, rub resistance is high.This is also the maximum reason that some clients favor in laser burn code mark.Therefore, the main problem to be solved that laser film be combined with Quick Response Code is distinguished exactly, is scanned.
The method of current open-type anti-counterfeiting mark processing: be first coated with last layer separation layer (white A) at common plastic film (PET, BOPP) substrate backside, then the pattern printing in front is carried out, white A layer carries out the coding of Anti-fake digital, finally coats hot melt adhesive and compound base stock at compound working procedure.Conclusion is: complex process, and yield rate is low, is difficult to corresponding positive and negative, and some transfers are incomplete, do not have laser anti-counterfeit effect, only open inquiry effect, the reason such as Yin Wendu, humidity, very easily cause the number on white A infull when opening.
Summary of the invention
