Abstract

The present invention relates to a four-dimensional holographic optical column antifalse identification making method, ad it relates to a method for making picture and characters applied identification. Said method includes: 1. utilizing three-dimensional program 3D software to make ideal optical column form, and simulating scanning state of natural optical column and making 3-200 optical column effect pictures with different angles and progressively-changed form; 2. using electronic dichroic output philin to make the said pictures into reversal film; 3. making every film undergo the process of zinc plate corrosion respectively to make die-pressing plate; 4. placing the die-pressing plate with first picture, starting dieing machine and printing the pattern on the aluminium-plate film, printing all the patterns with different angles on the aluminium-plated film; 5. die-cuttingand cleaning printed aluminium-plated film.

Description

The method for making of four-dimensional holographic light beam anti-counterfeiting label

Technical field: the method for making that the present invention relates to a kind of picture and text labeling.

Background technology: holographic security technology is from beginning to be applied to present first generation laser embossed holography image anti-counterfeiting technology, the improved laser hologram image of second generation anti-counterfeiting technology, the third generation encryption holographic security technology of having experienced.There is following problem in they: 1, only rely on the secret and control of manufacturing technology to come false proof.2, belong to simple observation class anti-counterfeiting technology, its observation point mainly is to see whether be hologram image, next is to see whether pattern meets the pattern of announcement, and its image produces prismy diffracting effect when light angle changes, and the shape of picture and text own does not change.Ordinary consumer only just can be told the hologram marking of two kinds of different editions when careful contrast.3, improved holographic security technology has just increased visual manufacture difficulty to some extent, does not have to give up the false proof inadequate natural endowment of hologram image, and original problem still exists.Generally believe the encryption holographic security technology that technology content is higher now, at first be the image that random phase encoding is encrypted,, present hi-techization, international today in fraud though need special instrument just can show, still have the possibility of forging, and the consumer can not discern.

Summary of the invention: forge easily owing to pattern can not change for solving present holographic false proof mark, and the consumer is difficult to the problem of identification, the invention provides the method for making of the holographic light beam anti-counterfeiting label of a kind of four-dimension.Concrete making step of the present invention is: 1, utilize three-dimensional program 3D software development to go out desirable light beam image, based on this light beam image, the simulating nature light beam is strafed state, produces the light beam design sketch that the shape of 3 width of cloth to 200 width of cloth different angles gradually changes; 2, the photo of several different angles light beams figure of making in the said process is made reversal film by the electronic scanning output film; 3, the film is made moulded board by the photo zincography corrosion respectively; 4, the mold pressing version that will be shaped on first width of cloth figure goes up block press earlier, starting block press is printed on pattern on the aluminizer, the moulded board of last second width of cloth figure after first width of cloth pattern is all printed and finished, second width of cloth pattern is printed on the aluminizer, and the like up to all being printed on the aluminizer pattern of all angles; 5, will print successful aluminizer and carry out the processing of cross cutting stripping, make the holographic false proof mark.Combination hologram of the present invention be with tens in addition the different two dimensional image of hundreds of by tens even the hundreds of hologram that time exposure is write down.Its effect can embody from two aspects, the one, be similar to the plane dynamic design, can take the plane dynamic change pattern of various styles, the 2nd, utilize 3D software or by digital camera, with each side of objective and over time process record get off, make four-dimensional hologram, promptly this hologram not only can write down and reproduce the three dimensions (X of object, Y, Z) characteristic, can also write down and reproduce the variation of (T) in time of this three-dimensional body, this is the high hologram of a kind of anti-counterfeiting performance, compare with common 2D/3D or true 3D hologram, have following characteristics: 1, quantity of information is huge, complex manufacturing technology: common holographic false proof labeling often by several times the exposure just can finish, and make four-dimensional hologram need to tens in addition hundreds of frame two-dimensional image carry out record, thereby exposure frequency is tens even hundred times of common holography, and this needs special-purpose instrument and equipment and exquisite more technological process to realize.2, take without limits picture, expanded the range of application of this high-tech means of laser hologram: common holographic recording three-dimensional model needs 1: 1 model entity to take, four-dimensional holographic information of then at first gathering object from all angles, then the two-dimensional image that collects is synthesized and make hologram, thereby without limits to the object taken, can be true man, true object, or even the illusory object of computer body plan.Ratio also need not 1: 1.3, true color four-dimensional display, common hologram marking is too far behind to catch up, and traditional hologram marking can only be realized the plane stereovision, and three-dimensional hologram also can only show the 3 D stereo feature of 1: 1 still life, and can not reduce the euchroic coloured silk of object.Four-dimensional holography is then different, along with viewing angle changes, the picture and text shape is three-dimensional and changes, as in true color reaction three dimensions object, can also this three dimensions of appendix over time, such hologram marking such as same abundant in content small tv, the deviser can write freely and easily in the above heartily.Imitated person is difficult to imitated, has improved the anti-counterfeiting performance of sign.

Description of drawings: Fig. 1 is the light beam design sketch that the shape of the different angles of made in the manufacture method of the present invention changes gradually, and Fig. 2 is a structural representation of printing process in the manufacture method of the present invention with block press.

Embodiment: the method for making of the four-dimensional holographic light beam anti-counterfeiting label of present embodiment is: 1, utilize the 3D software development to go out desirable light beam image, based on this light beam image of making, the simulating nature light beam is strafed state, produces the light beam design sketch that the shape of a series of tens width of cloth or width of cloth different angles up to a hundred changes gradually.2, the photo that will go up several different angles light beams figure that makes in the process is exported the film (being the common printed film of using) by electronic scanning and is made reversal film.3, the film is made the mold pressing version by the photo zincography corrosion respectively.4, the mold pressing version that will be shaped on first width of cloth figure at first goes up block press, starting block press is printed on pattern on the aluminizer 2, last second (second width of cloth figure) mold pressing version after first width of cloth pattern is all printed and finished, second width of cloth pattern is printed on the aluminizer, and the like all be printed on the aluminizer up to pattern all angles.See Fig. 2, pressure roll 1, aluminizer 2 and the moulded board 3 of block press wherein arranged.5, will print successful aluminizer carries out the cross cutting stripping and handles and to make the holographic false proof mark.
