The carved picture is composd of the sheet metal to be carved, which possesses the reflected mirror surface. The cognizable original pictures such as face photos, fingerprints, signatures and special trade marks etc. are made by the carving machine. The light reflected from the surface of the carved sheet metal forms the visual vendible image of the carved picture.
Description
The present invention relates to a kind of engraving process of picture; The present invention also relates to a kind of engraving picture that is used on the certificate.
Be applied in false proof photo on the personalized identity documents in early days and be photo carving on a dark and opaque thin plate, utilize its gloomy shadow that presents to recognize the true and false of certificate.This class engraving photo still can utilize black ink to distort, and therefore still needs careful careful inspection could recognize the true and false of this photo.Japan 52-29221 patent once disclosed the true and false that a kind of method is come the picture of this class engraving of identification on opaque thin plate.Its principle is to utilize a kind of engraving facility with pyramid tip that picture is carved on this opaque thin plate; If utilizing together, the parallel beam of specific incident angle shines this picture, because light is for this class engraving picture, has specific reflection angle thereon, and this specific reflection angle is relevant with the tip of engraving facility, as long as thereby look for the true and false that the folded light beam of this special angle can this engraving picture of identification.In addition, Japanese 6-15794 patent also discloses a kind of thin plate that is formed by light tight film and light transmission film manufacturing, and this thin plate then can be used for making the engraving picture.
Yet, above first kind of method that is disclosed being mentioned, the shape of its engraving tool must meet designing requirement in advance, simultaneously, observe the light of special angle also need specially designed machine just can reach.And top second kind of method that is disclosed mentioning in copying the process of identical picture, must be peelled off light tight film earlier, utilizes white ink again, to form the negative film of picture.But if the method for this class of utilization engraving picture, back side inconvenience of this engraving thin plate stamps other patterns or literal again, thereby the range of application of this class engraving picture that has narrowed.
So, one of purpose of the present invention provides a kind of method for making of carving picture, the simple mechanisms that the picture made from the method can utilize direct vision to observe its reflection ray is judged the true and false of this picture, thereby attempts change and forge this type of picture difficulty more.
Another object of the present invention then provides the engraving picture of a kind of very difficult change and forgery, and can be applied on the identification system of certificate.
For reaching the above purpose, the present invention is achieved through the following technical solutions:
The method for making of the engraving picture that a kind of part of providing evidence uses is characterized in that its step comprises:
Prepare an engraving thin plate with specular reflection surface in advance; The photo image that one scan obtains as graphic documentation;
Then, drive engraving facility and do the mechanical type action, wherein this mechanical action is carved this photo image on this engraving thin plate with reference to this graphic documentation, if Direct observation is somebody's turn to do the engraving thin plate, this engraving picture can't form visually generally accepted image whereby.
One parallel beam of surperficial oblique irradiation towards this engraving thin plate observed the surface of this engraving thin plate with this engraving picture of identification in a certain specific oblique angle simultaneously; Confirm the authenticity of this certificate by this photo image of relatively this engraving picture and confession reference.
Wherein, the step of this scanned photograph image further comprises the step that this graphic documentation is inverted to the negative film image data.
Wherein, this pre-prepd step further comprises and rolls its surface of one deck and have the carving layer of properties of specular reflection on substrate.
Wherein, the step of this driving engraving facility further comprise in depth portray to should the photo image than dark areas on this carving layer, and portray superficially to should the photo image than bright area on this carving layer.
Wherein, this step further comprises this photo image heat is transferred on this engraving thin plate.
The engraving photo of making by above-mentioned method for making of the present invention is characterized in that: this engraving picture is made of an engraving thin plate with specular reflection surface, have on it one by the engraving facility portrayed out cognizable original figure.
Therefore, the picture that portrayal is come out by the properties of specular reflection of engraving thin sheet surface, visually can generally be considered as an engraving pattern similar to original figure with accepting.
These engraving facility are according to the negative film information of original image, and part portrayal that can original figure is darker deep is for brighter part portrayal superficial relatively then.When one parallel beam tilt be radiated on this engraving picture the time, the formed reflected light of carve of part will go to the angle of inclination of part every bit to decide its reflection angle according to being carved.Yet the part of being gone by carving is not still possessed the characteristic of its direct reflection, thereby reflected light can be observed in the direction of specular angle.
Make the engraving picture according to method proposed by the invention and visually also can't directly go out a generally accepted image by its top view.Desire produces visually cognizable image, must under the irradiation of directional light special angle that is predetermined of picture inclination just can be observed.Therefore, if this engraving picture is changed or forged via the mode of xeroxing, just identification is come out easily.To meet with bigger difficulty if attempt to utilize ink to change this engraving picture, because the surface that will produce as the minute surface is quite difficult.
For desiring as for the photo of identity document, black-and-white photograph can be converted into reverse negative film figure information by simple device, and depict the engraving photo according to this information, thereby no matter be people's facial photo or trade mark photo, the engraving photo that can obtain having high reliability easily.
Therefore, the engraving picture of making according to method provided by the invention, it has and is difficult to the characteristic of changing and forging, thereby can provide as needed facial photo on the similar article such as the bond of I.D., credit card, passport, commercial distribution or stock, fingerprint, signature or specific trade mark etc.This engraving picture also can not directly utilize colored the photomechanical printing to forge.By traditional colored facial photo and have anti-fraud functional engraving facial photo, judge that the true and false of certificate will be more easy and accurate.For the commercial bond of issuing or stock,, in that being issued on the market the time, it can reduce the possibility that it is forged for many companies if particular brand is printed on it with the engraving picture.
For the method for making that the present invention is used for the engraving picture on the anti-fake certificate, the feature of engraving picture itself and the method for check of genuineness thereof are understood in depth, existing conjunction with figs., enumerate specific embodiment and be described in detail as follows:
Description of drawings:
Fig. 1 is the engraving photo that utilizes engraving process of the present invention made, and its specific embodiment is used for front elevation on the I.D.;
Fig. 2 is the skeleton view that is applied to the engraving thin plate on the identity document;
Fig. 3 A and Fig. 3 B are the cardinal principle of engraving photo application on identity document that illustrates this invention.
As shown in Figures 1 and 2, for utilizing the made engraving picture of engraving process of the present invention, and with this photo application on identity document, and can be used as the specific embodiment of the true and false purposes of identification certificate.As shown in Figure 2, this identity document 10 is to be made of one that the downcuts engraving thin plate 10a with the equal size of identity document.This engraving thin plate 10a be a kind of by chemical combination resin substrate 11 with roll the sandwiching thin plate that carving layer 12 thereon constitutes.This carving layer 12 is to form by the silver-colored film that rolls one deck eight micron thickness and have a smooth surface.Colored half body photo on the certificate can utilize the mode of hot transfer printing, this photo is imprinted on carving layer 12 surfaces with minute surface characteristic.Similarly, when desiring the literal 17 of printing necessity on certificate, also can utilize the technology of hot transfer printing to reach; And be carved at picture under this colour facial photo 15, then be engraving photo 16 corresponding to this facial photo 15.
For the message that will carve picture is transferred to the engraving facility, at first must should colour facial photo 15 via the scanning of scanner one rule, then this graphic documentation is converted to the image data of black and white form, again this black-and-white image is converted to reverse negative film image data at last.As shown in Figure 2, these engraving facility 9 scan in X-direction linearly, and can and then move towards Y direction when finishing in each bar scanning of X-direction simultaneously: as for the direction of Z axle, it then is the degree of depth that decides engraving by input carved image data, that is to say that these engraving facility 9 can be driven freely and control in three mutually perpendicular directions.These engraving facility 9 have the tip of a triangular-section, can carve carving layer 12.For the brighter zone of negative film image, that will portray on carving layer 12 is deep.For zone darker in the negative film image then is the superficial of portrayal, thereby will still possess the characteristic of minute surface corresponding to this carving layer 12 of dark areas.
If will check a people's identity and entrained identity document thereof, can check earlier at first whether the colored facial photo 15 on this person and this certificate meets, then can utilize the light beam that produces by special light sources together, special fluorescent light for example, apart from the place of these identity document 10 some distances to its oblique irradiation, thereby the prosecutor can observe the parallel beam with certain degree and comes out from the surface reflection of this identity document 10.Since on carving layer 12 corresponding to colored facial photo 15 darker parts portrayed deep, therefore can not cause any direct reflection phenomenon, shown in Fig. 3 B.When this colour face 15 became lighter, it is superficial that the degree of depth of portrayal then becomes; Thereby near the direct reflection quality areas of specular reflection also will be along with increase.Therefore, by visually can being approved, also can allow prosecutor judge the true and false of this colour facial photo 15 simultaneously corresponding to the engraving photo 16 of this colour facial photo 15.
For old engraving photo, the portrayal degree on dark-coloured layer has determined the exposed degree of substrate, just represents the shade of grey in the photo.For this class photo, prosecutor and being not easy differentiates the difference between engraving photo and the old black-and-white photograph, moreover difference therebetween also is not easy to notice via naked the looking of human eyes, thereby come forged certificate to become quite easy by the mode of photo transfer printing.Compare with old engraving technology,, the engraving photo made by this invention also can't visually form generally accepted image at first blush; Must shine to special angle and with parallel beam by this engraving photo that tilts, make being projeced into that light beam can be oblique carve on the photo, as shown in Figure 3A, thus prosecutor's image that can be produced in some certain tilt angles via visual observation easily judge the true and false of certificate.Therefore, this engraving photo also can not be forged via simple image transfer printing.Moreover this surface with minute surface characteristic makes this engraving photo to change without authorization by the mediation of ink.
The present invention is used for confirming that the application of personal identification has more than is confined on the above-mentioned I.D., also can be applied on passport, credit card and the similar article.Another specific embodiment of engraving figure chip technology of the present invention then is to be applied to many companies at commercial bond of issuing or stock, mainly forges because of it can't utilize colored mode of xeroxing, make these bonds or stock circulate on the market safer.Must provide the trade mark of some necessary information and distributing and releasing corporation on these bonds and the stock, and these information can be portrayed all on the engraving thin plate.Similarly, trade mark that these are commercial or pattern can convert negative form to via the image information, portray corresponding figure on the engraving thin plate to drive the engraving facility.
Carving layer on the engraving thin plate also can roll other metal material and make on this substrate, as gold, aluminium or other similar material, so the characteristic of direct reflection still can be possessed in its surface.Similarly, for the chemical combination resin sheet of individual layer, if it has the surface of direct reflection, even do not have substrate under this layer, this chemical combination resin sheet still can be used as good engraving thin plate.In this case, because the chemical combination resin has high reflectivity, thereby can improve its reflecting effect.The subuliferous cross sectional shape of engraving machine also is not limited to equilateral triangle.In fact, the engraving facility tip of Any shape is all applicable, as long as when becoming lighter in the circular negative film information, these engraving facility can depict less and more shallow relatively zone and get final product.
