Description

Technical Field

[0001] This invention relates to the field of anti-counterfeiting technology, and in particular to coded anti-counterfeiting elements and methods for manufacturing such elements. Background Technology

[0002] In the world of collectibles, items with special serial numbers often fetch significantly higher prices than similar items. This is especially true in banknote collecting, where banknotes with consecutive digits of 8 or 6 can sell for several times more than those with ordinary serial numbers. For example, a certain commemorative banknote with a serial number ending in "888" sells for approximately ten times the price of a banknote with an ordinary serial number. In response to this, counterfeiters have begun using new methods to forge and alter banknotes with special serial numbers in order to gain illicit profits.

[0003] One method involves cutting multiple coded sections of a banknote into layers (without damaging the images and text on the other side), and then swapping the positions of the cut sections to transform the banknote from an ordinary coded note into a special coded note with greater collectible value. For example, by cutting the second digit "8" and the last digit "7" of a 100-yuan banknote with the ordinary coded GZ38923687 into layers and then swapping their positions, it can be counterfeited into a banknote with the special coded GZ37923688 (achieving the goal of ending with "88").

[0004] Another method involves cutting one or more serial numbers from multiple rolls of the same type of banknote (without damaging the images on the other side), and then replacing the serial number of another banknote with the cut-off serial number. This transforms ordinary serial numbers into special serial numbers that are more valuable for collectors. For example, cutting the "8" from two rolls of 100-yuan banknotes with ordinary serial numbers GZ38923687 and GZ76348624 and replacing it with another roll can create a counterfeit banknote with the ordinary serial number GZ76346624 and a banknote with the special serial number GZ37923888 (achieving the goal of having the last two digits "888").

[0005] Since the aforementioned counterfeiting methods only involve the coded area of ​​the banknotes (items), while the rest of the banknotes (items) are originals, this poses a serious challenge to the authentication work.

[0006] Therefore, providing a new anti-counterfeiting element with tamper-proof coding and its manufacturing method has become an urgent problem to be solved. Summary of the Invention

[0007] In view of the problems existing in the background art, the present invention provides an anti-counterfeiting element, comprising:

[0008] Substrate;

[0020] Furthermore, another aspect of the present invention provides a method for manufacturing an anti-counterfeiting element, comprising:

[0021] Provide base materials;

[0022] Set a standard code that is normally visible on the substrate;

[0023] A first anti-counterfeiting layer is provided on the substrate. The first anti-counterfeiting layer has a first anti-counterfeiting code. The first anti-counterfeiting code includes at least a part of the conventional code and / or a first encrypted code obtained by encryption calculation of the conventional code. The first anti-counterfeiting layer is visible under the first observation conditions.

[0024] A second anti-counterfeiting layer is provided on the substrate. The second anti-counterfeiting layer has a fixed non-coded mark and / or has a second anti-counterfeiting code. The second anti-counterfeiting code includes at least a part of the conventional code and / or a second encrypted code obtained by encrypting the conventional code. The second anti-counterfeiting code is the same as or different from the first anti-counterfeiting code. The second anti-counterfeiting layer is visible under a second observation condition, which is different from the first observation condition.

[0025] In some embodiments of the present invention, the method of manufacturing an anti-counterfeiting element includes assigning a preset code to the anti-counterfeiting element, setting a conventional code containing a portion of the preset code on the substrate, setting a first anti-counterfeiting layer having a first anti-counterfeiting code on the substrate, wherein the first anti-counterfeiting code contains another portion of the preset code, so that the conventional code and the first anti-counterfeiting code can together form the preset code that is visible under normal conditions, and under the second observation condition, the conventional code is still visible, while the first anti-counterfeiting code is not visible.

[0026] In some embodiments of the present invention, the method of manufacturing the anti-counterfeiting element includes forming a first anti-counterfeiting pattern on the first anti-counterfeiting layer by repeatedly arranging the first anti-counterfeiting code.

[0027] In some embodiments of the present invention, the method of manufacturing an anti-counterfeiting element includes forming a second anti-counterfeiting pattern on the second anti-counterfeiting layer by repeatedly arranging the second anti-counterfeiting code, wherein the second anti-counterfeiting pattern is the same as or different from the first anti-counterfeiting pattern.

[0028] In some embodiments of the present invention, the method of manufacturing an anti-counterfeiting element includes repeatedly arranging the second anti-counterfeiting code on the second anti-counterfeiting layer, wherein the second anti-counterfeiting code and the non-coded mark together form a second anti-counterfeiting pattern, and the second anti-counterfeiting pattern may be the same as or different from the first anti-counterfeiting pattern.

[0031] In some embodiments of the present invention, the method for manufacturing the anti-counterfeiting element includes overprinting the first anti-counterfeiting layer and the second anti-counterfeiting layer.

[0032] In the anti-counterfeiting element and its manufacturing method provided by this invention, at least a first anti-counterfeiting layer has a first anti-counterfeiting code directly or indirectly associated with a conventional code. Under normal conditions, the first and second anti-counterfeiting layers are set to be invisible, and the two layers have no impact on the overall visual effect of the anti-counterfeiting element. Under a first observation condition, the first anti-counterfeiting layer is visible (the first anti-counterfeiting code is visible), and the second anti-counterfeiting layer is invisible (the second anti-counterfeiting code and / or fixed non-coded marks are invisible). Under a second observation condition, the first anti-counterfeiting layer is invisible (the first anti-counterfeiting code is invisible), and the second anti-counterfeiting layer is visible (the second anti-counterfeiting code and / or fixed non-coded marks are visible). Thus, at least a unique and definite correspondence is achieved between the first anti-counterfeiting code and the conventional code. Even if the numbers contained in the conventional code in the anti-counterfeiting element are layered, cut, transposed, and / or replaced, the error in the correspondence between the first anti-counterfeiting code and the conventional code can be easily detected through authentication. Furthermore, the two anti-counterfeiting layers help enhance the diversified visual effects produced by the anti-counterfeiting element under both the first and second observation conditions. When the second anti-counterfeiting layer also has a second anti-counterfeiting code that is directly or indirectly related to the regular code, the above-mentioned anti-counterfeiting effect is further enhanced. The anti-counterfeiting element provided in this embodiment can effectively prevent counterfeiters from forging or altering ordinary codes into special codes with greater collectible value.

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Although exemplary embodiments are disclosed in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to facilitate a thorough understanding of the invention and to fully convey the inventive concept to those skilled in the art.

[0045] like Figure 1 As shown, this embodiment provides an anti-counterfeiting element, including a substrate A, a conventional code B, a first anti-counterfeiting layer C, and a second anti-counterfeiting layer D. The conventional code B, visible under normal conditions, is disposed on the substrate A. The first anti-counterfeiting layer C is disposed on the substrate A and has a first anti-counterfeiting code, which includes at least a portion of the conventional code B and / or a first encrypted code obtained by encrypting the conventional code B. The first anti-counterfeiting layer C is visible under a first observation condition. The second anti-counterfeiting layer D is disposed on the substrate A and has a fixed non-coded mark and / or a second anti-counterfeiting code, which includes at least a portion of the conventional code B and / or a second encrypted code obtained by encrypting the conventional code B. The second anti-counterfeiting code may be the same as or different from the first anti-counterfeiting code. The second anti-counterfeiting layer D is visible under a second observation condition, which differs from the first observation condition.

[0046] exist Figure 1In the anti-counterfeiting element shown, the regular code B is displayed as "123456". The first anti-counterfeiting code on the first anti-counterfeiting layer C contains a part of the regular code B, specifically the last four digits "3456". The first anti-counterfeiting code can also contain the first four digits "1234" or the middle four consecutive digits "2345" of the regular code B. The first anti-counterfeiting code can also contain three or two digits of the regular code B, etc. The second anti-counterfeiting layer D contains a non-coded mark "☆☆☆☆".

[0047] exist Figure 2 In the anti-counterfeiting elements shown, the conventional code B is displayed as "123456". The first anti-counterfeiting code on the first anti-counterfeiting layer C contains a part of the conventional code B, that is, it contains the last four digits of the conventional code B, "3456". The second anti-counterfeiting layer D contains the second anti-counterfeiting code "3456", that is, the second anti-counterfeiting code is the same as the first anti-counterfeiting code.

[0048] exist Figure 3 In the anti-counterfeiting elements shown, the conventional code B is displayed as "123456". The first anti-counterfeiting code on the first anti-counterfeiting layer C contains a part of the conventional code B, that is, it contains the last four digits of the conventional code B, "3456". The second anti-counterfeiting layer D contains the second anti-counterfeiting code "1234", that is, the second anti-counterfeiting code is different from the first anti-counterfeiting code.

[0049] exist Figure 4 In the anti-counterfeiting elements shown, the regular code B is displayed as "123456". The first anti-counterfeiting code on the first anti-counterfeiting layer C contains a part of the regular code B, namely, the last four digits of the regular code B, "3456". The second anti-counterfeiting layer D contains the non-coded mark "☆☆☆☆" and the second anti-counterfeiting code "3456".

[0050] In addition, the first and second anti-counterfeiting codes can also be encrypted codes obtained by encrypting the regular code B. The encryption relationship (correspondence) can be as follows:

[0051] Parity method: Even numbers in the regular code B are recorded as 1 or 0, and odd numbers are recorded as 0 or 1 respectively, to obtain an intermediate code composed of 1 and 0. The sub-encryption code Y1 is obtained after calculation according to the preset number base rules.

[0052] For example, the regular code B is "34856321". If the numbers are distinguished by parity, with even numbers recorded as 0 and odd numbers recorded as 1, then the intermediate code "10010101" is obtained. Then, according to the preset hexadecimal rules, the sub-encryption code Y1 is calculated to be "95".

[0053] Grouping method: The numbers in the regular code B are recorded as 0 or 1 according to the interval 0 to X. Then (X+1) to 9 are recorded as 1 or 0 respectively, resulting in an intermediate code composed of 1 and 0. The sub-encryption code Y2 is obtained after calculation according to the preset number base rules, where X is an integer.

[0054] For example, the regular code B is "34856321". If the numbers are recorded as 0 in the range of 0 to 4, then 5 to 9 are recorded as 1, resulting in the intermediate code "00111000". Then, according to the preset hexadecimal rules, the sub-encryption code Y2 is calculated to be "38".

[0055] Summation method: Summing the numbers in the regular code B yields the intermediate code, which is then used to calculate the sub-encryption code Y3 according to the preset number base rules.

[0056] For example, the regular code B is "34856321". If the numbers are summed, the intermediate code "32" is obtained. Then, according to the preset hexadecimal rules, the sub-encryption code Y3 is calculated to be "20".

[0057] The sub-encryption codes Y1, Y2, or Y3 obtained by the above-mentioned odd-even method, grouping method, and summation method can all be used as the first encryption code or the second encryption code on their own. Furthermore, any combination of any two or any combination of the sub-encryption codes Y1, Y2, and Y3 can also be used as the first encryption code or the second encryption code.

[0058] For example, sub-encryption codes Y1 ("95"), Y2 ("38"), and Y3 ("20") obtained using the above method can each be used individually as the first and second encryption codes. Furthermore, the combined first and second encryption codes can be "953820" (i.e., Y1Y2Y3), "9520" (i.e., Y1Y3), or "3895" (i.e., Y2...).

[0059] Y1).

[0060] "Normal conditions" refers to the state under which observation and / or detection are not performed with the aid of other tools, such as under natural light or ordinary lighting.

[0061] "Fixed non-coded marks" can be represented as "☆", "$", "※", "☆☆", "☆※" and other complex graphics (e.g., portraits, landscapes), etc. "Fixed non-coded marks" appear repeatedly on each anti-counterfeiting element and do not change.

[0062] In this embodiment, the "first observation condition" can be ultraviolet light, and the "second observation condition" can be infrared light.

[0063] Those skilled in the art should understand that in the anti-counterfeiting element provided in this embodiment, at least the first anti-counterfeiting layer C has a first anti-counterfeiting code directly or indirectly associated with the conventional code B. Under normal conditions, the first anti-counterfeiting layer C and the second anti-counterfeiting layer D are set to be invisible, and the two anti-counterfeiting layers have no impact on the overall visual effect of the anti-counterfeiting element. Under the first observation condition, the first anti-counterfeiting layer C is visible (the first anti-counterfeiting code is visible), and the second anti-counterfeiting layer D is invisible (the second anti-counterfeiting code and / or the fixed non-coded mark are invisible). Under the second observation condition, the first anti-counterfeiting layer C is invisible (the first anti-counterfeiting code is invisible), and the second anti-counterfeiting layer D is visible (the second anti-counterfeiting code and / or the fixed non-coded mark are visible). Thus, at least the first anti-counterfeiting code has a unique and definite correspondence with the conventional code B. Even if the numbers contained in the conventional code B in the anti-counterfeiting element are layered, cut, transposed, and / or replaced, the error in the correspondence between the first anti-counterfeiting code and the conventional code B will be easily detected through authentication. Furthermore, the two anti-counterfeiting layers help enhance the diversified visual effects produced by the anti-counterfeiting element under the first and second observation conditions. When the second anti-counterfeiting layer D also has a second anti-counterfeiting code that is directly or indirectly associated with the regular code B, the above-mentioned anti-counterfeiting effect is further enhanced. The anti-counterfeiting element provided in this embodiment can effectively prevent counterfeiters from forging or altering ordinary codes into special codes with greater collectible value.

[0064] Furthermore, the anti-counterfeiting element has a preset code, with the regular code B containing a part of the preset code and the first anti-counterfeiting code containing another part of the preset code, so that the regular code B and the first anti-counterfeiting code can together form a preset code that is visible under normal conditions, and under the second observation conditions, the regular code B is still visible while the first anti-counterfeiting code is not visible.

[0065] exist Figure 5 In the anti-counterfeiting element shown, the regular code B contains a portion "12" of the preset code "123456", and the first anti-counterfeiting code contains another portion "3456" of the preset code, so that the regular code B and the first anti-counterfeiting code can together form the preset code visible under normal conditions (the first observation condition is the normal condition). Under the second observation condition, the regular code B is still visible, but the first anti-counterfeiting code is not visible (the fixed non-coded mark and / or the second anti-counterfeiting code are visible). The second anti-counterfeiting layer D contains the non-coded mark "☆☆☆☆".

[0066] exist Figure 6In the anti-counterfeiting element shown, the conventional code B contains a portion "12" of the preset code "123456", and the first anti-counterfeiting code contains another portion "3456" of the preset code, so that the conventional code B and the first anti-counterfeiting code can together form the preset code visible under normal conditions (the first observation condition is the normal condition). Under the second observation condition, the conventional code B is still visible, but the first anti-counterfeiting code is not visible (the fixed non-coded mark and / or the second anti-counterfeiting code are visible). The second anti-counterfeiting layer D contains the second anti-counterfeiting code "3456".

[0067] exist Figure 7 In the anti-counterfeiting element shown, the conventional code B contains a portion "12" of the preset code "123456", and the first anti-counterfeiting code contains another portion "3456" of the preset code, so that the conventional code B and the first anti-counterfeiting code can together form the preset code visible under normal conditions (at which point the first observation condition is the normal condition). Under the second observation condition, the conventional code B is still visible, but the first anti-counterfeiting code is not visible (the fixed non-coded mark and / or the second anti-counterfeiting code are visible). The second anti-counterfeiting layer D contains the second anti-counterfeiting code "1234".

[0068] exist Figure 8 In the anti-counterfeiting element shown, the regular code B contains a portion "12" of the preset code "123456", and the first anti-counterfeiting code contains another portion "3456" of the preset code, so that the regular code B and the first anti-counterfeiting code can together form the preset code visible under normal conditions (at which point the first observation condition is the normal condition). Under the second observation condition, the regular code B is still visible, but the first anti-counterfeiting code is not visible (the fixed non-coded mark and / or the second anti-counterfeiting code are visible). The second anti-counterfeiting layer D contains the non-coded mark "☆☆☆☆" and the second anti-counterfeiting code "3456".

[0069] Those skilled in the art should understand that in the anti-counterfeiting element provided in this embodiment, at least the first anti-counterfeiting layer C (which can also be regarded as the first anti-counterfeiting code) has a unique and definite correspondence with the conventional code B. Because the observation conditions (imaging conditions and / or effects) are different, the numbers contained in the first anti-counterfeiting code and the conventional code B cannot be layered, cut, and swapped or replaced. When the second anti-counterfeiting layer D (which can also be regarded as the second anti-counterfeiting code) also has a unique and definite correspondence with the conventional code B, the above-mentioned anti-counterfeiting effect is further enhanced. The two anti-counterfeiting layers help enhance the diversified visual effects produced by the anti-counterfeiting element under the first and second observation conditions. The anti-counterfeiting element provided in this embodiment can effectively prevent counterfeiters from forging or altering ordinary codes into special codes with greater collectible value.

[0070] Furthermore, the first anti-counterfeiting code is repeatedly arranged on the first anti-counterfeiting layer C to form the first anti-counterfeiting pattern P1.

[0071] Furthermore, the second anti-counterfeiting codes are repeatedly arranged on the second anti-counterfeiting layer D to form a second anti-counterfeiting pattern P2, which may be the same as or different from the first anti-counterfeiting pattern P1.

[0072] Furthermore, the second anti-counterfeiting code is repeatedly arranged on the second anti-counterfeiting layer D. The second anti-counterfeiting code and the non-coded mark together form the second anti-counterfeiting pattern P2. The second anti-counterfeiting pattern P2 may be the same as or different from the first anti-counterfeiting pattern P1.

[0073] like Figure 9 As shown, the second anti-counterfeiting code "6321" is repeatedly arranged on the second anti-counterfeiting layer D, and forms a circular second anti-counterfeiting pattern P2 with the non-coded mark "☆" at intervals (if the anti-counterfeiting element is a banknote or other item with a face value, the second anti-counterfeiting pattern P2 can be arranged around the face value).

[0074] like Figure 10 As shown, the second anti-counterfeiting code "9520" is repeatedly arranged on the second anti-counterfeiting layer D and forms a wavy anti-counterfeiting pattern P2 with the non-coded mark "☆" spaced apart.

[0075] Furthermore, one of the first anti-counterfeiting layer C and the second anti-counterfeiting layer D is printed with infrared invisible ink, and the other is printed with colorless fluorescent ink.

[0076] Furthermore, the first anti-counterfeiting layer C is printed with infrared reflective ink, and the second anti-counterfeiting layer C is printed with infrared invisible ink or colorless fluorescent ink.

[0077] Furthermore, the first anti-counterfeiting layer C and the second anti-counterfeiting layer D are overprinted (adjacent, nested, partially overlapping, completely overlapping, etc.).

[0078] When printing multiple anti-counterfeiting elements, if the anti-counterfeiting layer has a fixed, non-coded mark, then traditional printing technology is more appropriate. If the anti-counterfeiting layer has a variable anti-counterfeiting code, then digital inkjet printing technology is more appropriate.

[0079] Those skilled in the art should understand that the first anti-counterfeiting layer C and the second anti-counterfeiting layer D are printed with different anti-counterfeiting inks and have different imaging conditions, giving the anti-counterfeiting elements a more colorful color display effect. The overprinting of the first anti-counterfeiting layer C and the second anti-counterfeiting layer D further increases the difficulty for counterfeiters to transpose and / or replace the numbers contained in the first anti-counterfeiting code (first anti-counterfeiting pattern P1) and / or the second anti-counterfeiting code (second anti-counterfeiting pattern P2), thereby ensuring that the first anti-counterfeiting code (which can also be regarded as anti-counterfeiting pattern P1), the second anti-counterfeiting code (which can also be regarded as anti-counterfeiting pattern P2) have a unique and definite correspondence with the conventional code B or the preset code.

[0080] Furthermore, the anti-counterfeiting components provided in this embodiment include, but are not limited to, various high-security products and high-value-added products such as banknotes, credit cards, passports, and securities, as well as various packaging papers and boxes.

[0081] like Figure 11 As shown, another aspect of the present invention provides a method for manufacturing the anti-counterfeiting element as described above, comprising:

[0082] Provide substrate A;

[0083] A standard code B, which is normally visible, is set on substrate A;

[0084] A first anti-counterfeiting layer C is provided on substrate A. The first anti-counterfeiting layer C has a first anti-counterfeiting code. The first anti-counterfeiting code includes at least a part of the conventional code B and / or a first encrypted code obtained by encryption calculation of the conventional code B. The first anti-counterfeiting layer C is visible under the first observation conditions.

[0085] A second anti-counterfeiting layer D is provided on substrate A. The second anti-counterfeiting layer D has a fixed non-coded mark and / or has a second anti-counterfeiting code. The second anti-counterfeiting code includes at least a part of the conventional code B and / or a second encrypted code obtained by encryption calculation of the conventional code B. The second anti-counterfeiting code is the same as or different from the first anti-counterfeiting code. The second printing layer D is visible under a second observation condition, which is different from the first observation condition.

[0086] Those skilled in the art should understand that in the anti-counterfeiting element manufactured using the manufacturing method of the anti-counterfeiting element provided in this embodiment, at least the first anti-counterfeiting layer C has a first anti-counterfeiting code directly or indirectly associated with the conventional code B. Under normal conditions, the first anti-counterfeiting layer C and the second anti-counterfeiting layer D are invisible, and the two anti-counterfeiting layers have no impact on the overall visual effect of the anti-counterfeiting element. Under the first observation conditions, the first anti-counterfeiting layer C is visible (the first anti-counterfeiting code is visible), and the second anti-counterfeiting layer D is invisible (the second anti-counterfeiting code and / or the fixed non-coded mark are invisible). Under the second observation conditions, the first anti-counterfeiting layer C is invisible (the first anti-counterfeiting code is invisible), and the second anti-counterfeiting layer D is visible (the second anti-counterfeiting code and / or the fixed non-coded mark are visible). Thus, at least the first anti-counterfeiting code has a unique and definite correspondence with the conventional code B. Even if the numbers contained in the conventional code B in the anti-counterfeiting element are layered, cut, transposed, and / or replaced, the error in the correspondence between the first anti-counterfeiting code and the conventional code B will be easily detected through authentication. Furthermore, the two anti-counterfeiting layers help enhance the diversified visual effects produced by the anti-counterfeiting element under the first and second observation conditions. The manufacturing method of the anti-counterfeiting element provided in this embodiment can effectively prevent counterfeiters from forging or altering ordinary codes into special codes with greater collectible value.

[0087] Furthermore, the manufacturing method of the anti-counterfeiting element includes assigning a preset code to the anti-counterfeiting element, setting a conventional code B containing a portion of the preset code on a substrate A; setting a first anti-counterfeiting layer C having a first anti-counterfeiting code on the substrate A, the first anti-counterfeiting code containing another portion of the preset code, so that the conventional code B and the first anti-counterfeiting code can together form a preset code visible under normal conditions, and under a second observation condition, the conventional code B is still visible, while the first anti-counterfeiting code is not visible.

[0088] Furthermore, the method for manufacturing the anti-counterfeiting element includes forming a first anti-counterfeiting pattern P1 by repeatedly arranging the first anti-counterfeiting code on the first anti-counterfeiting layer C.

[0089] Furthermore, the method for manufacturing the anti-counterfeiting element includes forming a second anti-counterfeiting pattern P2 by repeatedly arranging the second anti-counterfeiting code on the second anti-counterfeiting layer D, wherein the second anti-counterfeiting pattern P2 is the same as or different from the first anti-counterfeiting pattern P1.

[0090] Furthermore, the method for manufacturing the anti-counterfeiting element includes repeating the second anti-counterfeiting code on the second anti-counterfeiting layer D, wherein the second anti-counterfeiting code and non-coded marks together constitute the second anti-counterfeiting pattern P2, and the second anti-counterfeiting pattern P2 may be the same as or different from the first anti-counterfeiting pattern P1.

[0091] Furthermore, the method for manufacturing the anti-counterfeiting element includes printing one of a first anti-counterfeiting layer C and a second anti-counterfeiting layer D on a substrate A with infrared invisible ink, and printing the other with colorless fluorescent ink on the substrate A.

[0092] Furthermore, the method for manufacturing the anti-counterfeiting element includes printing a first anti-counterfeiting layer C on a substrate A with infrared reflective ink, and printing a second anti-counterfeiting layer D on the substrate A with infrared invisible ink or colorless fluorescent ink.

[0093] Furthermore, the manufacturing method of the anti-counterfeiting element includes overprinting the first anti-counterfeiting layer C and the second anti-counterfeiting layer D (adjacent, nested, partially overlapping, completely overlapping, etc.).

[0094] When printing multiple anti-counterfeiting elements, if the anti-counterfeiting layer has a fixed, non-coded mark, then traditional printing technology is more appropriate. If the anti-counterfeiting layer has a variable anti-counterfeiting code, then digital inkjet printing technology is more appropriate.

[0095] Those skilled in the art should understand that the first anti-counterfeiting layer C and the second anti-counterfeiting layer D are printed with different anti-counterfeiting inks and have different imaging conditions, giving the anti-counterfeiting elements a more colorful color display effect. The overprinting of the first anti-counterfeiting layer C and the second anti-counterfeiting layer D further increases the difficulty for counterfeiters to transpose and / or replace the numbers contained in the first anti-counterfeiting code (first anti-counterfeiting pattern P1) and / or the second anti-counterfeiting code (second anti-counterfeiting pattern P2), thereby ensuring that the first anti-counterfeiting code (which can also be regarded as anti-counterfeiting pattern P1), the second anti-counterfeiting code (which can also be regarded as anti-counterfeiting pattern P2) have a unique and definite correspondence with the conventional code B or the preset code.
