[technical field]
The present invention relates to flat ticket false proof information Recognition field.Anti-counterfeiting information coding on flat ticket uses a kind of special coating to cover with the nominal value printing and realizes simultaneously, the hide information that is capped is specified special-purpose by applying unit or controlling unit, inquiry office, the general user does not grasp recognition methods, can't read internal information yet.The special-purpose recognizer that only is authorized to just can be distinguished.This invention is with stealthy printing technology and the special coating cover type design of encoding of the specific information of independent research, and three gordian techniquies such as special-purpose recognizer are the comprehensive automatic identification technology that core constitutes a system.Ticket false proof printing technique-conventional barcode, matrix bidimensional sign indicating number, digital watermarking paper or coded digital sequence number etc. different and in the past are exposed to ticket surface, are easy to be replicated and palm off.It is a kind of novel invisible information false proof technology.
Make to be printed on the ticket originally that non-visual information is coded under one deck special coating, stealthy not visible, and coding is intact after scraping off surface coating, recognizer reads rapidly accurately.This invention has changed the judgment mode that traditional anti-counterfeit recognition is exposed to the block letter surface, and employing simply scrapes off coating and uses the machine-readable mode of special-purpose recognizer to inquire about coded message, judges true and false.Ticket anti-pseudo technology and electronic recognition equipment are integrated, and the anti-counterfeiting technology that makes flat ticket false proof sign printing be stopped at the top layer has entered real stealthy invisible, as anti-ly attack, difficulty a to be duplicated New Times.
[summary of the invention]
This invention is that core constitutes an integrated anti-counterfeit technology with the point-like information coding of independent research, miniature plate-making, special anti-forgery ink printing, four gordian techniquies of special-purpose recognizer.The present invention is coded in the point-like information of printing and does not stay the printing vestige on the ticket, has changed traditional false proof mode, adopts special-purpose recognizer recognition, and is true promptly true, false promptly false, true and false can't confusing.Make the ticket anti-pseudo technology enter new epoch.
[point-like information coding]
As shown in Figure 1, by the basic figure that braille six brailles amplifications comes, point-like information coding is the medium of beared information, and the printing by specialty inks is implemented on the paper, and on behalf of one group of point-like information, every width of cloth braille figure encode.
[miniature plate-making technology]
As shown in Figure 2, the careful strictness of plate-making link of the present invention, flat ticket false proof printing technique has used point-like information coding, only extracting wherein one group or fractions class uses technical at flat ticket false proof, be implanted on the flat ticket appointed positions by electronic composition during printing, its message code is 25 * 25 braille point-like figure, after dwindling than former design configuration ratio, make film sheet with computer, on the PS version that hectographic printing is used, realizing printing simultaneously through the overscanning processing and fabricating with ticket, the PS galley of false proof point-like information coding is installed on the offset printing unit, start synchronously, having changed in the past, anti-counterfeiting mark and icon anti-counterfeit printing are the outsourcing processing modes.Printer's blanket, PS version etc.
[specialty inks printing]
As shown in Figure 2, point-like information coding of the present invention must use the corresponding special anti-forgery ink printing of the present invention, leave no trace on the printed article surface, specialty inks contains the infrared element of specific wavelength, have only and the supporting use of recognizer, general printing ink does not possess this characteristic, has only specialty inks not have point-like communication icon information coding of the present invention, special-purpose recognizer of the present invention can normally not read yet, and must could work through authorizing.
[covering coding coating]
Adopt the lead powder printing coatings that can buy in the market to cover coding, or the coating such as greasepaint that can lightly strike off, guarantee that coded message is not exposed to the surface, strengthen anti-attack ability.After scraping off the coating top layer, point-like figure is not destroyed, recognizer reading identification easily.
[special-purpose recognizer]
As shown in Figure 3, its internal electron integrated chip functional structure is divided into four parts: 01 takes the photograph bat part, 02 radio frequency part, 03 digital conversion part, 04 information statement part.Automatic recognition principle of the present invention is: the front end of pen type recognizer is equipped with a high pixel takes the photograph the bat camera lens, take the photograph bat operating system by infrared with high frequency, take the photograph bat to being printed on the paper non-visual point-like information coding, 01 figure of taking is passed to the built-in chip disposal system of recognizer carry out digitized processing, through 02 radio frequency, 03 digital conversion, 04 information statement program, finish the information statement again by its inner integrated circuit (IC) chip grouping.From using the pen type recognizer of this invention, from the opening power to information, to explain automatically, recognition time is within 1 second, and recognition speed is fast, examination is accurate.
