Description
Technical field
The present invention relates to transfer paper, particularly have the false proof transfer paper of memory cipher and detecting device and the detection method thereof that the duplication handwriting that uses such transfer paper to write or print is detected.
Background technology
At present the anti-counterfeiting technology of transfer paper has following several principal mode: 1, adopt water marked paper to make, similar banknote use paper; 2, employing has the line coated paper to make; 3, adopt coloured or the colorless fluorescent anti-fake material is made or the like.The no carbon paper of Chinese patent (application number) 94116732.1 band latent images, it is in the process of making the no carbon paper body paper, add one latent image and form operation, this procedure can increase the dandyprat of a setting identification figure at wire-cloths, forms watermark on the l Water Paper page or leaf; Or add dandy roll at the drying process of paper technology, on the no carbon paper body paper, extrude the figure of similar watermark, obtain no carbon paper body paper after drying with the watermark figure, and then through later process coating processing, because the covering of coating makes marked graph form latent image; Or by mode of printing the sign figure being imprinted on carbonless copying body paper surface before the painting process in processing no carbon paper process, coating again because the covering effect of coating makes marked graph form latent image, thereby obtains the no carbon paper of band latent image.The detection method of the no carbon paper of this band latent image needs the printing opacity observation just can see.Chinese patent (application number) 02130754.7 color veiled-image anti-fake paper and preparation method thereof, it is coated in pressure sensitive leuco dye microcapsule emulsion on the common paper, coating of paper substrate once used more than two kinds, by the copy printing technology, the leuco dye microcapsules of different colours are coated on the paper substrate, form latent image.The production method and the purposes of Chinese patent (application number) 95100687.8 colored flowers, strip coated carbon and this transfer paper are put after it prepares copying paper paint to the color separation printing and dyeing maker that heating arrangement is arranged, and make transfer paper by required rib escutcheon.Chinese patent (application number) 93244191.2 anti-fake bills, it is between invoice conterfoil part and the invoice reimbursement connection a special transfer paper that has double-colored coating to be housed.Be shaped on and the travers of this transfer paper background color coating different colours manifolding coating with each relevant position, hurdle of invoice conterfoil part on this transfer paper.Chinese patent (application number) 02200025.9 pressure sensitive false proof bill, it is coated with the different stealthy transferable fluorescent ink coating of color respectively at the back that amount in Chinese character " ten thousand ", " thousand ", " one hundred " of last paper, middle paper locates.Chinese patent (application number) 97118495.X has the no carbon paper of fluorescent latent image anti-counterfeiting mark, and it increases specific fluorescent latent image anti-counterfeiting mark figure on each body paper, and latent image shows the fluorescence falsification preventing effect under UV-irradiation.Chinese patent (application number) 96100339 anti-fake fluorescent pressure-sensitive carbon papers, Chinese patent (application number) 96100340.5 produces anti-fake fluorescent pressure-sensitive carbon paper of invisible duplication handwriting and preparation method thereof, Chinese patent (application number) 99106888.2 produces the false proof pressure-sensitive carbon paper of using of invisible fluorescent duplicated writing, Chinese patent (application number) 99106889.0 anti-fake fluorescent pressure-sensitive carbon papers etc., on them, scribble or be printed on colourless coating or colored coating or the printing ink that contains organic Ultraluminescence coordination compound with the paper and the middle back side with paper, write or produce when typewriting duplication handwriting stealthy or that show one's color with them, under the UV-irradiation of particular range of wavelengths, can demonstrate implicit fluorescence color.The weak point of such transfer paper is that this technology detects just whether fluorescent material is arranged in the writing, and such technology is imitated easily, only needs to mix fluorescent powder when making this transfer paper and has just become, and is forged by common producer easily.The above-mentioned technology of enumerating false proof transfer paper respectively has relative merits, but is imitated by the people than being easier to.
Summary of the invention
In order to overcome the weak point that existing transfer paper anti-counterfeiting technology exists, the invention provides and a kind ofly be difficult to imitatedly, be easy to discern the false proof transfer paper with memory cipher of its duplication handwriting true and false and detecting device and the detection method thereof that the duplication handwriting that uses such transfer paper to write or print is detected again.False proof transfer paper comprises pressure-sensing carbon paper and carbonless paper.
The false proof transfer paper of the present invention is achieved in that
