Abstract
The invention provides a multiple fake-proof print oil with memory code and its checking method, wherein the fake-proof print oil comprises stamp-pad ink, magnetic memory material and encrypted message therein, infrared fluorescent material and ultraviolet fluorescent material.
Description
Technical field
The invention belongs to the stamp-pad ink of affixing one's seal and printing usefulness, be called the multiple anti-fake stamp-pad ink with memory cipher and the detection method of printing product particularly.
Background technology
The anti-counterfeiting technology of stamp-pad ink has following several principal mode at present: 1, adopt the fluorescence falsification preventing material to make, detect with ultraviolet light; 2, adopt temperature to become material and make, detect with temperature variation; 3, adopt light to become material and make, observe by translation-angle and see that different colours detects; 4, adopt magneticsubstance to make, use the power in instrument detecting magnetic field or the like.96104762.3 1 kinds of anti-forgery penetrant atomic stamp pad inks of Chinese patent (application number) and preparation method thereof, Chinese patent (application number) 98119855.4 multifunctional antiforge stamp-pad ink manufacture method, Chinese patent (application number) 99125133.4 length ripple anti-counterfeiting stamp inks and anti-forgery ink etc., mainly be to take in stamp-pad ink, to mix luminescent phosphor, shine with ultraviolet light printing product then, utilize the fluorescence reverse signal to judge its true and false of identification, the weak point of this technology is that this technology detects just whether fluorescent material is arranged in the printing, such technology is imitated easily, only need when making stamp-pad ink, to mix fluorescent material and just become, be forged easily.Japanese Patent JP56115288 has introduced a kind of ink paste of making of temperature reversible color material, the printing of utilizing this stamp-pad ink to affix one's seal is met thermo-color, reach false proof purpose with this, to be the imitator mix when making stamp-pad ink the weak point of this technology that temperature becomes material has just become, and still is forged easily.Chinese patent (application number) 01122606.4 photochromatic printing ink composition and application thereof, having introduced a kind of optically variable pigments that added is the printing ink of main raw, its printing translation-angle is observed seen that different colours detects.93,112,618 1 kinds of magnetic colour-changing inks of Chinese patent (application number) and its production and application have been introduced and contained magnetic colour-changing film powder a kind of the adding among water white transparency printing ink, have reflected light with the printing of its printing and become effect and magnetic function.Chinese patent (application number) 94117784.X magnetic anti-forge printing ink, its antiforge function seems single.Chinese patent (application number) 9710137.5 magnetic stamp-pad ink and seal anti-false instrument thereof, it has been introduced and has a kind ofly responded to its magnetic signal by mix magnetic in stamp-pad ink with a kind of instrument of magneticinduction, and the power that detects magnetic field is judged the true and false of its printing of identification.The weak point of this technology is the power that is to detect magnetic field, because a lot of reasons all can change the power in magnetic field in the printing in the daily life, thereby judges that with the power that detects magnetic field the confidence level of its printing true and false of identification is not high.Above-mentionedly enumerate fairly simple that existing stamp-pad ink anti-counterfeiting technology has and imitated by the people easily, problem such as the complicated but false proof means of the manufacture craft that has are single.
Summary of the invention
