Abstract
The water display type hidden anti-fake method includes computerized design of multilayer film, coating the multilayer film, separating the multilayer film, crushing the multilayer film, mixing with print ink, printing and other steps. The present invention features the combination between the multilayer color-changing film technology and the 'water film' technology to reach the effect of dropping one drop of water to some specific area of the anti-fake product to display specific anti-fake pattern. The pattern will disappear after the water evaporates and displays color change with the altering viewing angle. The present invention has both public anti-fake function and expert anti-fake function.
Description
Technical field
The present invention relates to the explicit anti-counterfeiting technology of water, particularly based on the explicit invisible false proof technique of water of the colorless ink of multilayer optical film.
Background technology
Modern anti-counterfeiting technology mainly is divided into two big classes:
The one, the public is false proof, and is promptly so-called bright anti-, is characterized in the sign that the public is easy to discern in product powerful and influential place design, with the naked eye can distinguish the true from the false, and as various anti-false trademarks, sign, the watermark on the banknote, safety line, laser hologram trade mark, sign; Temperature induced color changing, photochromism anti-forging sign etc.The public is false proof will be by widely propaganda and teach knowledge and the method for distinguishing to the public socially, also simple and easy to do simultaneously, so just can reach and mobilize broad masses to contain the generation of fakement phenomena, but the false proof shortcoming of the public also is tangible, that is exactly: confidentiality is poor, and false proof intensity is low, the anti-counterfeiting technology characteristics has been exposed to the fake producer also meaning when the numerous common people propagate the anti-counterfeiting technology characteristics, therefore in some specific occasion, the public is false proof also false proof in conjunction with specialty.
The 2nd, professional false proof, promptly what is called is dark anti-, is characterized in: need by the secret mark on instrument, the recognition of devices product, password etc., as using ultraviolet lamp, infrared lamp, magnetic demoder, reaching computer picture, literal, password automatic recognition system etc.Specialty is false proof owing to adopt many secret marks of keeping secret, so in actual use except that fluoroscopic examination, major part is used for the professional false evaluation of distinguishing, often serve in judicial domain and the lawsuit activity, for example four kinds of secret marks of 100 yuans of new editions are also unexposed up till now, and its purpose is just in order finally to be judged the true and false of currency by the expert.
The principle that has interference effect between eighties of last century National Research Council of Canada in the latter stage eighties utilizes according to multilayer optical film has first been released the optically variable films anti-counterfeiting technology and at first adopted this technology on Canadian currency, it is reported that its antifalse effect is very desirable, there is the currency of many countries all to plan or adopted this technology now, China has applied for national patent (ZL931.12380.1) in 1993 by Shanghai Institute of Technical Physics of the Chinese Academy of Sciences, and present the 5th cover RMB has adopted the color shifting ink anti-counterfeiting technology based on multilayer optical film.
Summary of the invention
One of purpose of the present invention is to provide a kind of water explicit concealed anti-false method, and this method had both belonged to and is easy to popular the grasp and the false proof category of the public of operation, combines professional false proof characteristics again and is difficult to be copied by others.
