Description

There is the secure file of integrated yarn fabric
Technical field
The present invention relates to a kind of secure file of the complex extended with having planar, described complex is combined by multiple basalis.
Background technology
By the known multiple secure file of prior art, described secure file has or comprises card form complex.
All files with at least one following characteristics are called as secure file: described feature makes the copying of file, forge, copy or unwarranted manufacture becomes difficulty and/or impossible.Secure file comprises such as certificate, driving license, passport, identity card, access card, but also comprises credit card, stamp, stock, visa and similar, only lists at this.In order to be difficult to imitated and forge, make great efforts the security feature being difficult to as far as possible manufacture and/or copy to be integrated in secure file.In addition, make great efforts security feature to be configured to, namely described security feature can be verified simply and reliably.Checking is interpreted as the inspection to feature in authenticity and/or integrality.
Such as known a kind of with the secure file of code carrier form by EP 1 322 480, such as described secure file is especially for use in credit card or certificate.Code carrier has upper strata, and described upper strata has multiple lenticular lens at its lateral surface and has element shown at dorsal part, and described element shown can manifest around at least one axial-movement when code carrier overturns.Lenticular lens only extends on the subregion of described lateral surface.Element shown is safety element, and described safety element is stamped on inner card layer.
This element shown manifested movingly is also disclosed using the form of tilted image or as so-called CLI security feature and MLI security feature by prior art, wherein, file body is marked in the focal zone of lenticular lens by means of laser beam transparent lenticular lens.Can by different information labelings in file body for different incident directions.Under the different direction of observation corresponding to direction of illumination or incident direction, then can identify the different information formed by mark visually.The image identified is called Changeable Laser Images (variable laser image, CLI), swashs the direction change according to the observation of light-struck identified information because utilize.The mark of inserting at this marks also referred to as CLI.MLI is Multiple Laser Image (Multiple laser image).Term CLI and MLI is also for security feature, and in described security feature, lens element does not have cylindrosymmetry.
In a kind of secure file, the complex be made up of multiple basalis and other pages usually manufactured by paper substrate are combined into pamphlet or book.For this reason, an example is the passport with the passport card being configured to complex.Plastic material for constructing complex does not have enough elasticity and bending performance or bending property usually, can like that directly be bound in passport by sensitive paper page.
By the known multiple method for forming the complex with contact pin bar of prior art, described complex has required flexibility in bending stress and/or folding s tress, and can be bound into and have in the passport of other pages.
By the such as known a kind of pamphlet with individuation data page of EP 502 765 A1.Pamphlet has multiple page between front cover, and each page has front and back.Arrange at least one data page, described data page and front cover are permanently connected.Data page has flexible layer, and the layer of described flexibility is outstanding from data medium with a following region.In this region, data page is connected with front cover and remaining page.Flexible layer is such as by welding or being connected with pasting the layer plane other with at least one, and therefore, the attaching parts without the need to machinery releasably do not connect.
By the known a kind of insertion page for book formula identification file of DE 103 42 946 A1, a kind ofly identify file and a kind of method for the manufacture of book formula identification file, wherein, insert page to be connected along side with remaining page in folding region with seam.Insert page and comprise at least one layer be made up of thermoplastic elastomer (TPE) and at least one other layer.At least one other layer extends to folding region from the side opposed with seam substantially along the direction of inserting page plane, and at least one layer be made up of thermoplastic elastomer (TPE) extends in described folding region.Form the layer inserting page laminated each other.Thermoplastic polyurethane (TPU) is proposed as preferred thermoplastic elastomer (TPE).The plastics of high-temperature stable, such as Merlon (PC) are proposed to be used at least one other layer.In the plastics of high-temperature stable, realize the personalization of inserting page, described insertion page is the complex be made up of multiple layer.
But the practical experience with this passport book shows, when inserting the layer be made up of the plastics of high-temperature stable, such as Merlon (PC) that page comprises thermoplastic elastomer (TPE) and laminated at least one is other on described thermoplastic elastomer (TPE), may make to be provided with the pull-up that personalized PC layer forms from thermoplastic elastomer (TPE) again and unloading under expertly selective temperature and stretch capability.At this, in some cases, the pull-up that personalized PC layer may be made almost nondestructively to form from thermoplastic elastomer (TPE) unloads.This is very disadvantageous in the anti-counterfeiting of passport book.
Be present in the reason that layer on thermoplastic elastomer (TPE) and at least one other layer throw off each other to be again for making at least one subsequently, bi-material has different fusion temperatures.Therefore, in lamination, usually can not select a following temperature, make bi-material melt in boundary face and be connected to each other so at said temperatures, namely form the connection that can not without damage shirk.Being connected to of can not nondestructively shirking hereafter is interpreted as a following connection between the two layers, and described connection is not particularly deposited and can not again be shirked in the case of a fracture on the layer being provided with higher melting temperature.If be such as laminated on thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU) by Merlon (PC), Merlon (PC) can not be melted so at a too low temperature.Otherwise if select too high temperature, so there is following risk, make thermoplastic polyurethane (TPU) melt completely, this is disadvantageous for the shape stability of described thermoplastic polyurethane.Therefore, in common lamination, between the thermoplastic elastomer (TPE) in the thermoplastic materials of high-temperature stable laminated as practice do not show that enough performances are under any circumstance to guarantee without damage to connect with shirking.
Therefore, generally speaking, generation following problems for those skilled in the art of secure file, this improves following further, makes the imitated of secure file and/or forge become difficulty and propose the new-type security feature being difficult to copy.
Summary of the invention
Design of the present invention is, namely proposes a kind of new-type secure file, and yarn fabric is used as the part of complex by described secure file.Realize the security improved in the following manner, namely yarn fabric is selected like this and is arranged in like this in the complex of secure file, to make described yarn fabric overlapping with the diagram that can identify visually or can be overlapping and interact with described diagram, thus can through the upper side recognition image of complex, the content of described image is relevant with the identification direction of the upper side relative to complex.Therefore, this realizes in the reciprocation at least partially and between the diagram that can identify visually being arranged in the yarn fabric between the basalis in complex.

The yarn fabric manufactured by plastics silk thread is shown to be particularly suitable.Yarn fabric based on polyester silk thread is especially suitable for.Usually, have higher resistance to temperature change compared with the plastic-substrates that the silk thread be made up of polyester material and great majority use in secure file field, described plastic-substrates combines with laminating method.
Particularly preferably, the basalis being combined into complex is used to layer and the film of polycarbonate-base (PC), but also use other thermoplastics, such as ABS (acrylonitrile-butadiene-styrene (ABS) plastics), polyvinyl chloride (PVC), Polyethylene Terephthalates (PET), polyether sulfone (PES), polyether-ether-ketone (PEEK), polyphenylene oxide (PPO), polyphenylene sulfide (PPS), polybutylene terephthalate (PBT) (PBT), polyformaldehyde (POM), polysulfones (PSU), the layer of PEI (PEI) or polyamide (PA) and film.
Even if the material of yarn fabric has the softening temperature different from adjacent basalis, also the extraordinary connection of the different parts of complex can be realized, because connection can be formed through the free space be configured in yarn fabric adjacent basalis in lamination.Usually even can in laminating method with otherwise required when the tab portion section of plastics part or other sections are bound in complex compared with the lower temperature of selection and/or lower pressure, stable be protected from the complex handled and destroy to form.
But following embodiment is also significant, wherein, yarn fabric does not protrude from the remaining edge being combined into the basalis of complex.Yarn fabric can be integrated in complex, is arranged in all sidedly between the upper side of complex and downside to make described yarn fabric.
Arrange in one embodiment, around described yarn fabric ground in the plane that yarn fabric plane earth extends, in complex, there is the edge of adhesive-bonded fabric.Therefore, the danger suffering delamination failure is reduced significantly.
During fabrication, such as yarn fabric portion section is arranged on the base layer, one of basalis around edge keep being uncovered around described yarn fabric portion section.Then at least one other basalis is arranged on described basalis, and such as manufactures complex by means of laminating method.
But also can insert in composite members to be with strips by yarn fabric, described composite members extends in the whole extension of complex along a direction.
Other embodiment can have the comprehensive of yarn fabric but not protrude from the configuration at the edge of complex.
Arrange in an embodiment of the invention, at least one arrangement illustrated that can identify visually in complex itself, and at least one illustrated net grid that can identify visually that can identify visually at least partially by the covering being at least partially arranged in the portion's section between at least two basalises of yarn fabric.In the secure file so formed, the diagram that can identify visually is protected to exempt from imitated, because described illustrated configuration is in complex equally particularly well.Can arrange in other implementations, at least one illustrated configuration that can identify visually is on one of secure file other part.Therefore, particularly in the secure file being configured to passport book, interact can realize checking security feature by being embedded into yarn fabric in complex and the diagram that can identify visually be configured on passport page, the diagram that can be identified visually by least one and the interaction of yarn fabric form described security feature.
In this case, but also in other implementations can advantageously, namely complex comprises preferably opaque basalis, and described basalis has the vacancy of the portion's section can arranging yarn fabric, and described portion section is arranged between at least two basalises.Therefore, such as a see-through window can be set in complex.In addition advantageously, yarn fabric is embedded in the vacancy of the other basalis be arranged between at least two basalises, increases because avoid complex intensity based on additional textile material.Therefore, in following each region, obtain the smooth upper side of complex and the smooth downside of same acquisition complex, in this region, yarn fabric is arranged between at least two basalises.It should be noted, can arrange following complex yet, in described complex, yarn fabric does not protrude from the edge of at least two basalises, described in yarn fabric is arranged between at least two basalises.Therefore, the secure file of card form also meaningfully can be equipped with yarn fabric, and the secure file of described card form does not have the tab portion section for being bound in book formula secure file.
In following embodiment, greatly different images is obtained when only changing relative to upper side minutely and identify direction, wherein, at least one diagram that can identify visually perpendicular to the extension being arranged in the planar of the portion's section between at least two basalises of yarn fabric and described yarn fabric spaced apart.At this, when yarn fabric net grid and figure net grid overlap, the spacing of increase causes the stronger directional dependency of identified moire pattern.Therefore, preferably transparent basalis is arranged between yarn fabric and described basalis, on described transparent basalis or among arrange or construct at least one diagram that can identify visually.
The diagram that can identify visually can such as to comprise the formal construction of the net grid of fine and closely woven line.In one embodiment, at least one diagram that can identify visually is configured on substrate surface by means of printing process, and described substrate surface is preferably arranged in the inside of complex after layering step.But also possible that, at least one arrangement illustrated that can identify visually to be constructed by means of printing process preferably equally at this on passport page.
In an interchangeable embodiment, at least one diagram that can identify visually is with the formal construction of hologram.Equally preferably in described hologram, store net grid, when the portion's section through yarn fabric identifies, described net grid contribute to Moire effect (or Moire effect).Hologram is preferably reflection hologram, thus can realize being irradiated by the upper side of reconstruct light through complex, also carries out the identification to image by described irradiation.
But in an other embodiment, described hologram also can be transmission hologram, wherein, the irradiation being used for being reconstructed through the downside of complex is realized.The advantage that at least one diagram that can identify visually carries out constructing with the form of hologram is, on the one hand can realize very fine and closely woven net grid and another aspect makes to carry out the imitated of this net grid by fake producer for the structure of the net grid of printing significantly becomes difficulty.
Arrange in an other embodiment of the present invention, what make to identify visually by means of graphic structure element is shown in relevant depicted area midplane ground structure, wherein, by means of structural detail, information is encoded, and the net grid that can identify visually are not be configured in all sidedly in relevant territory, depicted area, but are only configured in the depicted area of structural detail or in the depicted area of multiple structural detail.In one embodiment, described structural detail can comprise such as alphanumeric symbol, table shape word, or also comprises the silhouette of head portrait profile or outline or similar image.Moire effect is only then visible in the region of graphic structure element, the information of described graphic structure element then can additionally still be identified uninterruptedly, however about figure or image the form of expression by with identify that the effect of directional correlation changes.
But the use of net grid is not the illustrated uniquely possible configuration that can identify visually, with the effect realized with identify directional correlation, described effect can realize in the interaction between yarn fabric and the diagram that at least one can identify visually.Arrange in one embodiment, being configured to transparent at least partially and constructing like this in filament cross-sectional of the silk thread of yarn fabric, particularly braid, when described silk thread is inserted between plastic material, described silk thread plays focussing force for the light in visible wave-length coverage, and described plastic material has the refraction coefficient different from the refraction coefficient of filament materials.
Therefore, arrange in one embodiment, the silk thread of braid is made up of transparent plastic material, described plastic material has a following refraction coefficient, described refraction coefficient is different from the refraction coefficient of the basalis being directly adjacent to yarn fabric or different with two refraction coefficients being directly adjacent to the basalis of yarn fabric, and described silk thread has a following shape of cross section, thus the light of at least one wavelength focuses on when passing, and direction is identified at least one, at least one diagram that can identify visually or other focal zone being shown in silk thread that can identify visually comprise the CLI mark for a CLI mark.In order to produce described CLI feature (its lens element constructs by means of the silk thread of yarn fabric), one in described basalis can be added additive, described additive contributes to the laser absorbing certain wavelength, and described wavelength is used for the special CLI of irradiation and marks.Described additive is constructed so that described additive does not damage or do not damaged the transparency of basalis in non-irradiated state with obviously awaring usually.Preferably then realize ad hoc irradiating CLI mark in complex by means of laser, the intensity of described laser is selected like this, and the important light absorption causing complex that the change that can identify visually occurs only occurs in the focus of silk thread or the scope of focal line.
Arrange in a further scheme of the present invention, at least one diagram that can identify visually or an other diagram that can identify visually comprise other CLI and mark, described CLI mark can be identified from the identification direction different from described identification direction or from the identification direction that multiple and described identification direction is different, and utilizes one or more other CLI information different from aforementioned CLI information by means of other CLI label codings to encode.
Therefore possible that, not only figure net grid but also CLI be marked at the interaction of the yarn fabric in secure file in use in combination.At this particularly preferably, CLI is marked in complex and is arranged between yarn fabric and figure net grid.
Use yarn fabric to be with the special advantage being formed lens element (in described complex, yarn fabric is arranged between basalis) in complex, not structurized level and smooth laminate can be used when laminated.Described not structurized level and smooth laminate compared with structurized laminate mainly cost lower and more wear-resisting, described structurized laminate is often used in forming lenticular lens in the surface of complex in the prior art.Relative to following embodiment, wherein, lens element is not that manufacture described herein and configuration have significant advantage by laminated but be such as placed on the surface of complex by means of stamping die subsequently yet.Which save process steps.Do not need to provide and obtain or reset the stamping die suffering noticeable wear yet.
Silk thread by means of yarn fabric forms an additional advantage of lens element and is, described lenticular element arrangement is inner and therefore prevented from forging by protection admirably and imitated at complex.
Particularly preferably, be embedded into by yarn fabric in the vacancy of an other basalis, the strength of materials of described basalis and the strength of materials of yarn fabric match.Therefore, can produce a complex in a straightforward manner when laminated, described complex has plane-parallel and level and smooth surface on upper side and downside.
The level and smooth upper side of complex and downside form an additional advantage, because can apply other layer (such as hologram layer or protective paint) on complex.Described layer does not negatively affect according to security feature of the present invention.Come from prior art have band gap tilt effect, Moire effect, exercise effect or 3D effect security feature secure file in, hologram or protective paint can be applied on described surface, because negatively lens arrangement can be affected at this.Described shortcoming is eliminated here in described embodiment.
If yarn fabric is not placed in the vacancy of basalis, the smooth surface of the plane of complex so usually also can be realized.But the higher temperature for forming described smooth surface and/or pressure is then usually particularly needed when having the yarn fabric of heavy thickness.Therefore, in such embodiment, preferably selecting the minimum preferably 10 μm to 150 μm of yarn fabric, is particularly preferably the layer thickness of 60 μm to 130 μm.
The basalis can inserting yarn fabric can be configured to transparent or translucent.But in most cases, basalis can be configured to opaque, thus exist on the position of yarn fabric at least through the see-through window of described opaque basalis.
Particularly preferably, composite construction be make described complex the upper side planar from complex the below of relevant range of extending be made up of the basic material of volume transparent (im Volumen Transparentem), overlapping at least partially of portion's section between at least two basalises of described relevant range and yarn fabric, described portion section cover at least one diagram that can identify visually at least partially, or can with the diagram that can identify visually described in the covering at least partially of described portion section; Or described complex is at least made up of the basic material that volume is transparent between upper side and the diagram that can identify visually.Because this ensure that, the interaction of diagram and the yarn fabric that can identify visually can be proved in the image of visual identity.The basic material that volume is transparent is interpreted as following material, can realize optical imagery through described material according to the principle of geometric optics system.Described material can have color, therefore can absorb the light of the single wavelength in visible range and the light of only transmission determination wavelength.It is transparent that a kind of following material also can be considered as volume, can form each mark in the material, such as mark with the CLI of optical density form.Can form each printed layers equally in the material to form, the plane but described printed layers does not allow to be configured in the following manner all to link up, namely described mode makes to carry out geometry imaging through described printed layers completely.
It is emphasized that also can be used in complex when not carrying out the function as folding element or link plate element for the yarn fabric forming security feature.
It is also possible that use the yarn fabric of two or more separate structure of turning up the soil in complex, to form two or more security feature or safety element, described security feature or safety element can be configured to identical or different.
Therefore, the yarn fabric that there is different filament strength and/or be made up of different materials can be used, to produce the lens with different focal.When different silk threads is processed in yarn fabric jointly, also described effect can be realized.
If yarn fabric is used as the part of CLI feature, so draw the high tamper-resistance properties preventing layering, because almost can not repeatedly embed or engage the yarn fabric with CLI information matches, described CLI information has been stored in the layer of complex.
If yarn fabric is not braid but such as non-woven fabrics, so based on the fiber in non-woven fabrics " scrambling " and carry out randomly to a certain extent to CLI mark storage and described storage can not reappear.But again can be read by non-woven fabrics by the information of CLI label coding, described non-woven fabrics is integrated in complex as yarn fabric.

Yarn fabric 41 is preferably configured to braid.But alternatively, as long as described knitted fabric is similar to the yarn fabric net grid 47 of the such composition rule of yarn fabric that silk thread 45 is formed, yarn fabric also can be knitted fabric.Silk thread 45 can not only be configured to transparent but also to be configured to in visible wavelength region only opaque.Preferably, yarn fabric net grid 47 are net grid of rule, in described yarn fabric net grid, form net grid unit that is foursquare or rectangle by warp thread 45-1 and weft yarn (not shown).
In embodiment in FIG, the diagram 61 that can identify visually prints on passport page 5 with the form of figure net grid 63.Figure net grid 63 are selected like this relative to the layout of portion's section 43 of yarn fabric 41, and namely yarn fabric net grid 47 are overlapping with figure net grid 63 planar ground.At this, the covering relevant to the observation of the upper side 31 perpendicular to complex 3 is regarded as the overlap of planar.This means as long as a part for portion's section 43 of yarn fabric 41 is along identifying that the overlap be projected at least one diagram 61 that can identify visually in direction causes the overlapping region of planar, then to there is described overlap.Figure net grid 63 are such as with line formal construction, and described line extends perpendicular to graphics plane.In addition correspondingly, the described warp thread 45-1 in portion's section 43 of such as yarn fabric 41 also orientation in parallel with each other.Yarn fabric net grid 47 have the net grid spacing 48 between warp thread 45-1, and described net grid spacing is slightly different from the net grid spacing 68 of figure net grid 63.Therefore, moire pattern 151 is produced when upper side 31 recognition image 150 along identification direction 171 through complex, described moire pattern is following net grid, and described net grid have net grid spacing 48 than yarn fabric net grid 47 and the net grid spacing 158 more much bigger than the net grid spacing 68 of figure net grid 63.
If identify that direction 171 slightly changes, so the moire pattern 151 of image 150 similarly changes.Thus, guarantee yarn fabric 41 to be bound in complex 3.
Except the line perpendicular to graphics plane orientation, net grid 63 also can have other lines of same intervals in one embodiment, described line is configured on passport page 5, and transverse to, be preferably perpendicular to the described line orientation extended perpendicular to graphics plane.The net grid spacing of other lines can corresponding to the net grid spacing 68 of the described line perpendicular to graphics plane extension.In other embodiment, the net grid spacing of other lines is different from the net grid spacing 68 of the described line extended perpendicular to graphics plane.But in one embodiment, net grid 63 also can be only made up of one group of parallel line, and described line is equally spaced apart as illustrated in fig. 1.
In said embodiment, an other diagram 71 that can identify visually is with the formal construction of CLI mark 73, and described mark schematically illustrates with the form of letter " A "., by the silk thread 45 of yarn fabric 41, CLI mark is imaged as the image that can identify visually of alphabetical A in shown identification direction 173 time.Therefore, additionally produce CLI feature, namely one other relevant to direction of observation or with identify the security feature that direction 173 is relevant, can the information being schematically illustrated as " A " at this be encoded in described security feature.
The embodiment that of Fig. 1 is other is similar to shown in Fig. 2.In all of the figs, identical technical characteristic illustrates with identical Reference numeral.Embodiment according to Fig. 2 is with the difference of the embodiment according to Fig. 1, in said embodiment, the figure net grid 63 of the diagram 61 that at least one can identify visually are configured on the material layer of complex 3 inside, and described material layer corresponds to the basalis border of lower basalis 39 and additional basalis 38.Additional basalis 38 preferably combines with portion's section 43 of laminating method and yarn fabric 41 together with upper basalis 35, lower basalis 37 and intermediate base bottom 39.The diagram 61 that at least one can identify visually is preferably stamped in the form of figure net grid 63 in described substrate surface.This can such as carry out during printing process, on one that utilizes described printing process to be stamped in by other security feature in described substrate surface.For the reason simplified, described other security feature is not shown and be certainly configured in complex 3 or passport page 5,7, in 9 at this.
The embodiment that of secure file 1 shown in Fig. 3 is other, described secure file with the formal construction of plastic cards for complex 3.In said embodiment, portion's section is not had to protrude from the edge 135,137 of basalis and lower basalis to form tab portion section in yarn fabric 41.In the described embodiment, intermediate base bottom 39 is configured to opaque.Yarn fabric 41 is arranged in the vacancy 40 of intermediate base bottom 39.Silk thread 45 forms yarn fabric net grid 47 again.In said embodiment, first diagram that can identify visually 61 is again with the formal construction of figure net grid 63, described figure net grid are consisted of arbitrary labeling method, such as printing process, in described labeling method, impress in described basalis before the combination.Preferably, print substrate surface, described substrate surface forms the material layer of complex 3 inside.
In order to the silk thread 45 of yarn fabric 41 can be utilized to form CLI effect, the material of filament materials and adjacent basalis 35,37 is compared has higher refraction coefficient.In said embodiment, schematically show different CLI information " A ", multiple CLI marks 73,75 of " B ".CLI mark 73,75 is respectively for identifying in the focal line of one of direction 173,174 silk thread 45 being in yarn fabric 41.CLI information A can be identified 173 times in identification direction, CLI information B can be identified 174 times in identification direction.In contrast to this, in the center top view along identification direction 171, only identify moire pattern 151, there is described moire pattern by the overlap of yarn fabric net grid 47 on figure net grid 63.When identifying that direction 171 changes, the image 150 identified and moire pattern 151 change at this.
An other embodiment shown in Fig. 4, in the described embodiment being different from Fig. 3, the first diagram that can identify visually 61, with the formal construction of holographic Figure 80, reappears the net grid that can identify visually in described hologram when hologram reconstruction.These net grid again form Moire effect when overlapping with yarn fabric net grid 47 in identified image 150, and wherein, described Moire effect is relevant with identification direction 171.It is important in this that, directional dependency is not determined by the directional dependency of holographic Figure 80, but the parallax between the figure net grid 63 of the reproduction when reconstructing by yarn fabric net grid 47 and holographic Figure 80 changes decision.This is so formed, and described hologram reappears almost constant figure net grid 63 in certain angular regions.Described net grid are such as made up of one group of line, described line is vertically or with an other angular cross being different from 90 °, wherein, line of this group has the constant spacing of the adjacent line organize with this respectively, therefore such as rhombus, rectangle or the foursquare net grid primary element of formation.If net grid have three groups of lines, leg-of-mutton net grid primary element so also can be produced.Net grid also can be made up of the parallel lines of one group of same intervals.Net grid also can be made up of the same geometry of regular arrangement, such as circle, point etc.Such as can produce following net grid, in described net grid, geometric figure is arranged on the crosspoint of the net grid that (but graphically not illustrated) of attaching troops to a unit is made up of line.
The top view on the complex 3 for being encased in passport written matter is schematically shown in Fig. 5.Can see yarn fabric 41 by the yarn fabric net grid 47 shown in solid line.Figure net grid 63 are shown by dashed lines.
The tab portion section 49 of yarn fabric protrudes from the upper basalis 35 of upper and lower arranged superposed and the edge 135,137 of lower basalis 37, and described upper basalis and lower basalis overlap in a top view.Described tab portion section is arranged between basalis 35 and lower basalis 37 in portion's section 35 of yarn fabric 41.Portion's section 43 of yarn fabric is overlapping with figure net grid 63, and described figure net grid to be such as configured in lower basalis 37 and to illustrate by means of dotted line.Form moire pattern when recognition image, described moire pattern can not be identified at this, because be selected as greatly with very different each other at this for the simple and clear net grid spacing 68 of object figure net grid and the net grid spacing 48 of yarn fabric net grid 47.For formation moire pattern importantly, the net grid spacing 48 of yarn fabric net grid 47 and the net grid spacing 68 of figure net grid 63 are not identical, but slightly different.It should be noted in this, the orientation of the orientation of net grid line, i.e. silk thread and the line such as printed of figure net grid need not orientation in parallel with each other.Slight rotation also causes Moire effect, but described Moire effect is different from the Moire effect produced when parallel-oriented.
The Moire effect of generation is schematically described in Fig. 6.Show the schematic top view of secure file, on described secure file, construct the figure net grid be made up of the green line replaced and yellow line all sidedly.The Lower Half of secure file 1 is covered by yarn fabric, and described yarn fabric has transparent silk thread.Can see the moire pattern with net grid spacing 158 well, the net grid spacing 68 of described net grid gap ratio figure net grid 63 is much bigger.The slight curves of the line produced in moire pattern is caused by the linearly extended slight deviations of yarn fabric silk thread.
At this, can such as identify distorting on secure file.Particularly such as butt strip portion section carry out new laminated time produce this change affecting moire pattern.
In the line situation of different colours, when identifying that direction changes, Moire effect also shows as the color change of pattern.
The example images that of the moire pattern produced shown in Fig. 7 is other, described moire pattern such as produces when the yarn fabric net grid of rectangular shape in addition rotate relative to figure net grid, and described figure net grid are made up of vertically extending fine and closely woven line.
With the schematic structure element of the form of alphanumeric symbol shown in Fig. 8, the depicted area 201-203 of described alphanumeric symbol is with the formal construction of thin-line-shaped figure net grid 63.When figure net grid are overlapping with yarn fabric net grid, produce in the region of structural detail 201-203 according to identifying the Moire effect that direction changes.But, additionally, described structural detail can be identified well before the background that Moire effect can not be shown, thus the information by means of structural detail coding can be identified.
To those skilled in the art, illustrate only the exemplary embodiment of secure file.
