Background technology
For example banknote is false proof on false proof mode, can be divided into public's level, teller's level, expert level Three Estate for the cheque paper anti-counterfeiting technology.Wherein, the false proof mode of public's level is the most intuitively, easily, also is anti-false the first line of defence.False proof to the public, the most effectively be characterized as: directly perceived, very clear, and can realize machine-readable detection, and have stronger anti-circulation.
False proof false proof and antiforge two aspects of base material that can be divided into again of cheque paper.During base material was false proof, the paper substrate material was false proof important component part, and the main component of cheque paper is a cotton fiber at present, requires paper to possess higher physics speciality such as stiffness, can use in a long time not to be destroyed.In the antiforge; Printing ink is another false proof important component part; Anti-forgery ink is broadly divided into fluorescent ink, magnetic ink etc.; But be attached to the printing ink of substrate surface, one of drawback that it is maximum is exactly the destruction that its effect can receive surperficial various physics, chemical action, and therefore can in the process of circulation, produce certain decline.
Along with the progress of science and technology, the situation of fast development has appearred in the antifalse material, for anti-forge paper improves anti-counterfeiting performance wide space is provided.From the angle of anti-circulation, the false proof additive in the banknote base material possesses stronger anti-circulation advantage because of it in paper inside.At present, in cheque paper, using the more false proof additive of the public has: false proof additives such as anti-false fiber, Anti-counterfeit piece and false proof point etc.The interpolation measure of existing these false proof additives in paper generally all is through being mixed in the paper pulp in tankman's preface, and implanted paper at wet end through once-forming with paper pulp, and mostly distribution form is that full version distributes.
The addition manner of above-mentioned false proof additive in paper said from preparation technology; Application in paper production can receive the restriction of factor aspect two: the one; Mix in the adding technology in traditional slurry, the production procedure of paper machine is longer, and the sheet anti-fake material can stop in refining, mediation, storage slurry process more than 10 hours even longer; And general slurry reaches as high as about 65 ℃ through boiling and its temperature of pulping process; Long-time high temperature, water logging cause the physical property of function/anti-fake material, result of use to reduce, and have influenced its effect; The 2nd; To the anti-fake material that discontinuous dispensing is arranged or have directed dispensing to require; Like: sheet, fibrous etc., can't realize that in order (control position, control to) add, its result is for anti-fake material is full edition, form appears at the different parts and the different aspects of paper at random; Because of its random distribution---each anti-fake material does not spatially possess certain reproducible or repeats rule, can't carry out machine-readable detection exploitation.In addition, the addition manner manufacture difficulty of this false proof additive in paper is relatively low, copies than being easier to.
In addition, from the circulation angle, the anti-circulation effect of cheque paper that the addition manner of above-mentioned false proof additive in paper manufactures is relatively poor; The anti-fake material of full version dispensing; Because evenly mix with slurry, anti-fake material can be randomly distributed in the inside or the surface of paper, especially when false proof flaky material proportion during less than water or slurry; It can be distributed in paper surface more; Therefore when printing, circulation or use, come off easily (particularly flaky material), cause the anti-trafficability performance of its antifalse effect to descend, influenced the logical effect of its subsequent flows.
