Embodiment
The present invention utilizes the collocation of the multiple parameter of a plurality of grating diffraction points, can produce the false proof design of multilayer simultaneously, and so-called here multilayer can be the difference of identification or interpretation method, or collocation is different with the effect that grating pattern demonstrates.
In the present invention, but one have diffraction grating point microstructure can become a material or coating materials with the collocation of the naked view appearance of a macroscopic.The naked view appearance of macroscopic can be the ink printing pattern, or optical grating point is formed, the cognizable pattern of human eye or the pattern image of no special aid, for example pattern, figure, literal, numeral etc.So-called here special aid does not comprise general spectacles, spectacles for long sight, astigmatic glasses etc., and promptly common people still range the situation of the human eye of no special aid because of myopia, long sight or the astigmatic glasses of wearing in the present invention.Two dimension (2-dimensional; Ink printing pattern 2D) has abundant color, and the optical grating point pattern then utilizes optical grating point (grating dot) diffraction to be incident to the reference light of optical grating point, with respect to the different visual angles of human eye; Can see the visible light of different colours; For example general dot matrix type full figure pattern, detailed technology can repeat no more in this with reference to the TaiWan, China patent No. 432229.Understandable, when the optical grating point pattern is applied to wrappage or label etc., can supply ordinary consumer with these wrappage of the direct identification of visual mode or label is commended or the true and false of the product that is adhered to, therefore have false proof function.
Secondly; The Multi-layer anti-counterfeit of the present invention of the following stated; With practical structure; But be to go out the unit of visible light basically as minimum with optical grating point diffraction, the variation and the combination of the grating angle (angle) of a plurality of optical grating points of arranging in pairs or groups, grating space (pitch), optical grating point size, optical grating point block unit (block unit of grating dot) cycle and dim spot (contain do not have optical grating point to exist or grating is filled or destroys leave a blank a little) etc.
Secondly; If with the pattern that shows; Pattern of the present invention; Can be made up of or overlapped one or more zone institutes such as printing zone, full figure effect zone, folded line pattern hidden area, private mark area of the pattern, scattering point zones, wherein printing zone and full figure effect zone are meant that the demonstration macroscopic can visual pattern or the part of pattern image, and other zone then is a cognizable part below the special aid.When the material of using pattern made of the present invention, worker's version or packing timber; Can only comprise visual part under the above-mentioned special aid; Or by macroscopic can visual pattern part and special aid under visual part form; Both all can be used as intermediate product and can continue processing, or as final products.
Moreover special aid of the present invention comprises lenticule array (an array of micro lens), optical microscope, laser light interpretation instrument etc.With one deck antifalse effect, but can be the interpretation of lenticule array,, can also maybe can not distinguish the knowledgeable for distinguishing the knowledgeable further with the optical microscope sight.
Ground floor of the present invention is false proof, forms, needs the cognizable small pattern of human eye (micro pattern, minute pattern, small literal, small numeral) of special aid etc. by optical grating point.So-called here small pattern, the human eye that does not promptly have special aid can not pick out the part of external form, profile or the formation of this small pattern, and the human eye that in the present invention, is called no special aid can not pick out the pattern image.Secondly,, can pick out the pattern image that those small patterns are contributed, below will explain with Fig. 1 by the human eye of lenticule array interpretation.Fig. 1 is the first embodiment of the present invention, and the structural representation that small literal (micro text), lenticule array interpretation sheet and small literal are formed is described.With reference to figure 1, material 10 has a small literal field 101, do not have the human eye of special aid can't the small literal field of identification 101 literal that desires show.When placing aid 12 on the material 10 and contacting material 10, human eye 5 can be seen the also literal image 121 of the small literal field 101 of identification.Be noted that in practical application the aid 12 of present embodiment is the surface that directly contacts material 10; For convenience of explanation; In this aid 12 is plotted on the certain distance of material 10, but in practical application, aid 12 can directly contact the surface of material 10.
In an embodiment, aid 12 comprises a lenticule array, and it has an one-period T1 and a focal length F1.101 of small literal fields are inserted small literal field 101 by a plurality of literal field module units 1011 with the two dimension repeatability cycle; Wherein the cycle of arbitrary at least dimension is T2; And each literal field module unit 1011 is formed with the two-dimensional array gathering by optical grating point, and each literal field module unit 1011 all has a literal body 10111.When the cycle T 1 of aid 12 equates with the cycle T 2 of literal field module unit 1011, under the situation with the fixed angle of visual material 10, can see the demonstration of literal image 121 by the top of aid 12.When aid 12 rotates, can see the difference of the enlargement ratio of literal image 121, and literal image 121 has positive and negative demonstration and shows the situation that the number number changes on material 10.So-called here positive and negative demonstration is meant that the literal image 121 that the observer sees can be identical with literal body 10111, " R " shown in for example on Fig. 1, or " R " opposite with literal body 10111.
According to above-mentioned, the observer can see through the literal image 121 that aid 12 sees that bore hole can't identification, and what the literal image 121 that therefore can be judged to read just can be as false proof sign is a kind of.
Secondly; Be noted that the literal image of being seen through the aid 12 of lenticule array type 121, it is the image that is obtained by 10111 contributions of a plurality of literal bodies; Therefore; Even if any literal field module unit 1011 of small literal field 101 is not identical, for the literal image of seeing through aid 12 121, may not necessarily produce the difference that is enough to by identification.Therefore, can design different literal field module units 1011, watch and be still identical literal image 121 but see through aid 12, and utilize other aid, optical microscope for example then can be observed the literal field module unit 1011 of different designs.
For instance; Each literal field module unit 1011 among Fig. 1 comprises literal body 10111 and character background 10112; Both all can comprise optical grating point and leave a blank arbitrary at least in the point; Bore hole can't both difference of identification, but under the interpretation of aid, are enough to highlight literal profile or the profile that 10111 desires of literal body show because of difference such as brightness.In an embodiment; Literal body 10111 is all literal " R "; But the character background 10112 in the upper left corner of Fig. 1 comprises leaving a blank a little of some quantity, and promptly the count grating of the character background 10112 that is less than other literal field module unit 1011 of the grating of the character background 10112 in the upper left corner is counted, and does not so influence the literal image of seeing through aid 12 121; But see through observation by light microscope, just can understand the grating of the character background 10112 in the upper left corner and count less.If it is applied on the antifalsification label; The overview person, for example the consumer perhaps can see through aid 12 and see literal image 121; But other observer; For example the path merchant can see through observation by light microscope, learns the different fabrication region of source form that grating with different literals background 10112 is counted.In another example, can also be that literal body 10111 comprises the optical grating point of varying number and leaves a blank and a little reaches false proof purpose, and be not limited to have the character background 10112 of leaving a blank a little.
Be noted that; But for the optical grating point that diffraction goes out visible light; So-calledly among the present invention leave a blank that a little can be that diffraction goes out the diffraction efficient of visible light relatively low, leave a blank and a little itself perhaps still can reflect or diffraction goes out invisible light, or utilize the incident laser light can produce diffraction effect person; Therefore, many modes capable of using make that the present invention is so-called to leave a blank a little.On be set forth in when making optical grating point, in the zone that optical grating point distributes, keep some positions with random number or specific mode and do not make grating, so can form leaving a blank a little among the present invention.Selectable; Directly write (laser direct-write) or the mode that electron beam is write (e-beam writer) with radium-shine; Produce in literal body 10111 or character background 10112 or both zones that the present invention is so-called to leave a blank a little, so mode still can see through the literal image 121 that aid 12 is seen; May not necessarily produce the difference that is enough to by identification, reach the false proof purpose of the second layer simultaneously.And otherwise, for example above-mentioned radium-shine directly write or the electron beam ways of writing is made leaves a blank a little can further be utilized alternate manner, and for example the mode interpretation of incident laser light or the record ordering of leaving a blank a little comes interpretation.
Secondly; The optical grating point sum of each literal field module unit 1011 of two small literal fields 101 is different; Though the literal image 121 that see through aid 12 this moment is identical; But see through observation by light microscope, the optical grating point sum that just can understand literal field module unit 1011 is also inequality, and the dimension of the literal field module unit 1011 of for example a certain small literal field 101 is 7*7; Be the zone that literal field module unit 1011 comprises 7 row and 7 row optical grating points (and leaving a blank a little), but the dimension of the literal field module unit 1011 of another small literal field 101 is 9*9.Thus; Though see through literal image that aid 12 sees 121 identical (comprise slightly luminance difference but do not influence interpretation and go out literal image 121); But see through observation by light microscope; Just can understand the optical grating point sum of literal field module unit 1011 and inequality, so the dimension of literal field module unit 1011 also can be used as the usefulness of interpretation, reach false proof effect.
According to above-mentioned; Leave a blank and a little can compoundly use with dimension; For example literal field module unit 1011 is being divided into four inferior block unit that do not wait, the position of leaving a blank a little in each time block unit is identical, but along with four the put in order differences of block unit in a literal field module unit 1011; Also can form different literal field module units 1011, not demonstrate literal image 121 but do not influence through aid 12 interpretations.Under the above-mentioned situation, leaving a blank does not a little influence dimension by the optical microscope identification.Yet, also can be according to the distribution of leaving a blank a little, making that the dimension of literal field module unit or inferior block unit becomes can not be by the optical microscope identification.Except literal field module unit 1011 being subdivided into time block unit; Also can the literal field module unit 1011 of some quantity be formed a huge block unit 102; So two or more literal field module unit 1011 layouts capable of using become huge block unit 102; So still can not have influence on the interpretability of literal image 121, can come identification according to the layout difference of 102 Chinese words block unit 1011, huge block unit again, form the false proof mode in another road simultaneously.
Except dimension, the several parameters of optical grating point itself also can change reaching further false proof purpose, and these parameters for example but be not limited thereto a bit, comprise grating angle, grating space, grating fringe number or optical grating point size.For instance, the grating angle serves as the reasonably visual resolution of differentiating with 30 degree, and the degree of freedom on 6 rank is just arranged for single optical grating point.Therefore, identical even if the grating of each literal field module unit 1011 of small literal field 101 is counted, but utilize the difference of grating angle design, still can under optical microscope, pick out different literal field module units 1011.Again, for instance, with the optical grating point of 6um diameter grade, fringe number can be 3～8 6 rank degree of freedom.So cooperate grating angle and fringe number, the optical grating point of each 6um size has 36 degree of freedom, for the literal field module unit 1011 that dimension is 8*8, then has the degree of freedom of 8*8*36 to set.Therefore, see through under aid 12 interpretations, the literal image 121 that human eye is seen is still kept identical, forms but can pick out by different literal field module units 1011 and different optical grating points under the optical microscope.
According to above-mentioned, further, pattern of the present invention more can combine the design of folded line pattern.Traditional folded line design details can form dislocation with the bright striped that secretly replaces of grating with reference to the TaiWan, China patent No. 424163, and the part that forms folded line pattern can be distributed in one or the many literal fields module unit 1011 in the small literal field 101.Thus, utilization can pick out this folded line pattern with the interpretation sheet of folded line pattern same period.In addition, pattern of the present invention also can combine the design of private mark pattern, and the design of traditional private mark pattern can be repeated no more in this with reference to the TaiWan, China patent No. 324811.
Above-mentioned pattern structure; Promptly see through the pattern that aid is seen, under the situation of fixed viewpoint and incident light incident angle, the form that the effect of pattern is being decided for two dimension; Along with the rotation of aid on material, pattern is the form dwindling, amplify, put upside down and the variation of visual quantity.Further; The pattern image that the present invention utilizes small pattern district to be appeared is the characteristic of being contributed by a plurality of pattern blocks unit; And the interpretation with aid of lenticule array type can have down dwindle, amplify, put upside down and the effect of visual number change under, but make the demonstration of two pattern relative motions and unsteady effect.
Fig. 2 is the second embodiment of the present invention, explains and utilizes two different folded synoptic diagram of scheming of pattern of cycle.With reference to Fig. 2, pattern block unit 1311 and 1313 stacks of pattern block unit form small pattern district 131.The pattern body 13131 of the pattern body 13111 of pattern block unit 1311 and pattern block unit 1313 is all a circular chart.Understandable, on the material 13 except naked look can't the small pattern district 131 of identification, also can comprise the naked naked view appearance of the macroscopic district 132 of looking cognizable.
In this embodiment, follow-uply will go out the circular chart image with the aid interpretation of cycle 100um (period 1).But float and the circular chart image of relative motion in order to go out two in follow-up interpretation; When design, the cycle of pattern block unit 1311 is designed to greater than 100um, for example 104um (second round); The cycle of pattern block unit 1313 is designed to less than 100um; 96um (period 3) for example, and the size of the optical grating point in the two pattern block unit is identical, for example 8um.Therefore, the dimension of pattern block unit 1311 then is 13*13, and the dimension of pattern block unit 1313 then is 12*12.When small pattern district 131 was formed by 1313 stacks of pattern block unit 1311 and pattern block unit, during by aid 14 interpretations of cycle 100um, but interpretation demonstrated two circular chart images 141,143.Because the cycle of pattern block unit 1311 and the cycle of pattern block unit 1313 are not equal to the cycle of the lenticule array with 100um cycle; So the image that human eye 5 is seen has unsteady situation generation; In second embodiment; The circular chart image 141 that 1311 contributions in a plurality of pattern blocks unit that human eye 5 is seen obtain has showy situation, and the circular chart image 143 that 1313 contributions of a plurality of pattern blocks unit obtain has the situation that sinks to.
Moreover; When with the aid 14 on the fixed-direction rotation material 13; Except the effect of dwindling amplification, human eye 5 still can be seen circular chart image 141 and the visual effect of circular chart image 143 towards the different directions motion, and therefore two pattern images have relative motion.So-called here visual effect towards different directions motion, for example circular chart image 141 can oriented moving clockwise except dwindling amplification, and this moment, circular chart image 143 then can oriented counterclockwise motion and the visual effect of dwindling amplification.Therefore, the circular chart image 141 that sees through aid 14 interpretations has three-dimensional with circular chart image 143, and (it can be used as a kind of false proof design for three dimensional, the 3D) visual effect of relative motion.
Further; Except folded figure is applied to the present invention, cooperate the design in cycle, can produce outside the visual effect of 3D and relative motion; The figure mode of tearing open of one pattern; Can produce aforementioned block unit of leaving a blank a little, and the boundary that can further break up the block unit, make can't pick out pattern when utilizing the optical microscope interpretation.For instance, a literal body with and the design of background, go out literal but make the observer see through the aid interpretation.But when plate-making; Be divided into literal field module unit and only have the literal field module unit of counting equal with literal body; Both all adopt the definition of straight parallel striped; The even number bar of getting the odd number bar of the literal field module unit with literal body and having a literal field module unit of counting equal combines, and each vertical bar line utilizes the mode of random number that the part luminous point is removed, and this follow-up becoming in a little positions is left a blank a little.
Therefore; When utilization has the aid interpretation of lenticule array; Literal can be judged to read out, but when further or directly utilizing observation by light microscope, then can't pick out the literal field module unit; Be that the boundary of adjacent literal field module unit can't see through optical microscope and learn, and the literal body of each literal field module unit also can't see through optical microscope and learn.Thus, this design of structure applications of the present invention can more increase by the difficulty of identification, improves counterfeit cost and door.
Pattern of the present invention can be made on the material, and for instance, Fig. 3 is one embodiment of the invention, but the diagrammatic cross-section of the coating materials of the microstructure that comprises diffraction grating point is described.One material comprises high molecular single or multiple lift material 153; Such as but not limited to, layer of polyethylene terephthalate (Polyethylene terephthalate, PET); And one processing layer 154 (primer) formed thereon; But the pattern that will comprise diffraction grating point again is passed on the processing layer 154, and a metal level is formed on the processing layer 154 as reflection horizon 155, but is the material 15 with microstructure of diffraction grating point of the present invention.
According to above-mentioned, but so material 15 has the microstructure that comprises diffraction grating point, but the microstructure of this diffraction grating point has a plurality of false proof means, and these a little false proof means all have the characteristic that the human eye of no special aid can't identification and the level of identification.
The false proof means of first level assisting down of lenticular optical element array, are picked out a pattern image by a plurality of small patterns contributions.The pattern image that false proof means showed of first level is by a plurality of small pattern contributions, and each small pattern is made up of a pattern block unit, and a pattern block unit consists essentially of a plurality of optical grating point arrays.Those small patterns microcosmic difference each other, major part can not have influence on the manifesting of macroscopic image of pattern, and therefore, those small patterns microcosmic difference each other just can be used as further false proof means.
The false proof means of second level, the utilization pattern block unit combination and wherein the dimension difference of optical grating point array realize.A kind of mode is; Become different huge block unit with some different pattern block unit cell arrangement, utilize a plurality of huge blocks unit to repeat being scattered in the pattern zone again, but Different products can be represented in the pattern block unit of different orderings; For example can represent different manufactured places; Thus, except false proof, also can be used as the usefulness of the management of product.Another kind of mode is that also inequality by the dimension that the pattern block unit that different manufactured place produced is included, for example the dimension of 7*7 and 9*9 is promptly inequality.The false proof means of this second level perhaps can see through observation by light microscope and learn.
Secondly; The false proof means of second level; Comprise and utilize desire to show the pattern block unit cycle and the cycle differentiation of interpretation instrument and the mode of folded figure of pattern image,, can produce the visual effect of relative motion that the desire display pattern has the component part of 3D and pattern by this interpretation instrument.
Moreover, the false proof means of tri-layer, the incompatible realization of parameter group of using each optical grating point.But the optical grating point of each diffraction comprises angle, spacing, size and regulates realization.For instance, even if the dimension of two pattern block unit is identical, but it is different to be present in the grating angle of the correspondence position in this two optical grating points array, so also can represent this two patterns block unit and inequality.For example identical again grating space, but the width ratio of bright dark line and inequality.For example combine the design of folded line that dark line is misplaced again, so false proof means also can see through observation by light microscope and learn.
The false proof means of the 4th level; Belong to the false proof means of deep layer; Pattern image in conjunction with scattering point or private mark pattern and desire demonstration; That is in the optical grating point array, be provided with or distribute be different from arround the point of optical grating point, the point of for example radium-shinely directly write, electron beam being write or leave a blank a little, or with at random or specific mode adjust optical grating point quantity or the mode of grating diffraction in the optical grating point array.Be noted that the first above-mentioned false proof means, in utilization to tri-layer; Can make up each other to confirm that as further the false proof means of the 4th level are in utilization; Can cover the false proof means of second level, make the false proof means of tri-layer be not easy to be identified.On the visual effect of performance first level or second level, the false proof means of different levels can not produce the false proof means of first level or second level to be enough to by the vision difference of identification.In addition, the utilization of the false proof means of the 4th level make to see through the false proof means that optical microscope is difficult for observing image and other level of pattern, but utilizes other identification instrument, and incident one laser light for example can be by identification.
According to above-mentioned, multi-level false proof means of the present invention are during the combination utilization; See through first aid; For example the interpretation instrument of lenticule array can produce common or the common visual effect, but sees through another aid; For example the mode of optical microscope or incident laser light then can be observed structural difference.Be noted that aforesaid identification level, be meant when the 4th layer of false proof means of utilization combine other means, if not when adopting the first auxiliary interpretation instrument, can't pick out pattern image or profile that desire shows, the level of this meaning identification.Therefore; Pattern of the present invention comprises a plurality of false proof means; See through the aid of an image identification; Those false proof means comprise that one shows the false proof means of an image of the image of this pattern, and comprise that one can cover the false proof means of deep layer of other false proof means, and its image that can cover pattern is come out by identification under other aid.
