Description

Technical Field

[0001] The present invention relates to the technical field of smart cards, and in particular to a smart card that uses dots to achieve a 3D depth of field perception and a manufacturing method thereof. Background Art

[0002] With the rapid development and changes in society, the types of smart cards are becoming more and more diverse. Information security methods are rapidly iterating, and the technology is becoming more and more mature. Smart card anti-counterfeiting is becoming more and more concerned by users.

[0003] The layout of existing IC smart cards does not have the characteristics of change, the appearance is single, the anti-counterfeiting is not high, and it is easy to forge. In addition, with the increase in personalized requirements, it is difficult to meet customer needs, which reduces customer expectations.

[0004] The utility model patent with publication number CN219686906U discloses a smart card with naked eye 3D effect, which realizes the visual difference effect of spatial depth of field through a printed layer with a cat's eye pattern. However, the cat's eye pattern of this scheme is etched on the substrate by laser, and in order to increase the adhesion of the cat's eye substrate layer, a primer layer is added, which has a high cost. Summary of the invention

[0005] The first object of the present invention is to provide a smart card that uses dots to achieve 3D depth of field perception, which achieves 3D depth of field perception at a low cost.

[0006] The second object of the present invention is to provide a method for manufacturing a smart card that realizes the 3D depth of field perception by using dots.

[0007] The third objective of the present invention is to provide another method for manufacturing a smart card that realizes the 3D depth of field perception by using dots.

[0008] In order to achieve the above-mentioned first purpose, the present invention provides a smart card that uses dots to achieve 3D depth of field perception, including a card base, wherein: the card base is a transparent material, the card base includes a refractive layer, an intermediate layer substrate and a dot layer, the refractive layer is arranged above the intermediate layer substrate, and the dot layer is arranged below the intermediate layer substrate; a first dot pattern is arranged on the refractive layer, and a second dot pattern is arranged on the dot layer, and the mesh angles of the first dot pattern and the second dot pattern differ by a preset angle.

[0009] It can be seen from the above scheme that the smart card of the present invention realizes a 3D depth of field perception by aligning the first dot group of the refractive layer and the second dot pattern on the dot layer. The realization cost is low, and the problem that the existing smart card surface elements are single and easy to imitate is solved. At the same time, it can meet more personalized requirements and make the smart card have better anti-counterfeiting characteristics.

[0010] A further solution is that the smart card that uses dots to achieve 3D depth of field perception also includes a lower printed substrate, the lower printed substrate is arranged below the middle layer substrate, and the dot layer is arranged on the lower surface of the lower printed substrate.

[0011] It can be seen that the second dot pattern can be directly printed on the lower printing substrate.

[0012] A further solution is that the smart card that uses dots to achieve 3D depth of field perception also includes an upper printed substrate, the upper printed substrate is arranged above the middle layer substrate, and the refractive layer is arranged above the upper printed substrate.

[0013] A further solution is that the printed content on the upper printing substrate has the same appearance as the first dot pattern on the refractive layer.

[0014] It can be seen that the first dot pattern of the refractive layer has the same appearance as the printed content on the upper printing substrate to achieve the best visual effect.

[0015] A further solution is that the smart card that uses dots to achieve 3D depth of field perception also includes an upper coating and a lower coating, the upper coating is arranged between the refractive layer and the upper printed substrate, and the lower coating is arranged below the dot layer.

[0016] It can be seen that the smart card can be better protected by the lamination setting.

[0017] A further solution is that the second dot pattern includes a plurality of cells, each cell is composed of a plurality of second dots, and the size of the second dots in the cell increases sequentially from the outer circle to the inner circle.

[0018] It can be seen that the second dot pattern disposed on the lower surface of the lower printing substrate needs to be arranged according to a specific rule and produced by four-color printing.

[0019] A further solution is that the cells are square cells, the square cells are composed of a preset number of second dots arranged in an array, and the diameters of the second dots in the square cells increase from the outer circle to the inner circle.

[0020] A further solution is that the screen angles of the first dot pattern and the second dot pattern differ by 45°.

[0021] It can be seen that a 45° difference in screen angles can provide a better visual 3D effect.

[0022] In order to achieve the above-mentioned second purpose, the present invention provides a method for manufacturing a smart card that uses dots to achieve a 3D depth of field perception, which includes: making a dot layer, including: designing a unit cell composed of second dots, arranging the unit cells horizontally and vertically, the spacing between adjacent units is a third preset value, and then cutting according to actual needs, and printing the cut shape on the lower surface of the lower printed substrate; binding an upper coating, an upper printing substrate, an intermediate substrate, a lower printing substrate, and a lower coating, and laminating them using a laminator to obtain a laminated card; designing a refraction layer, including: arranging first dots of a diameter of a first preset value horizontally and vertically, the center distance between adjacent first dots is a second preset value, and then rotating a preset angle, cutting according to actual needs to obtain a first dot pattern; printing or printing the refraction layer on the laminated card; cutting the laminated card to obtain a smart card of a preset shape.

[0023] As can be seen from the above scheme, the present invention prepares a dot layer, prints the dot layer on the lower surface of the lower printed electrode plate, and then obtains a laminated card by laminating other components of the card base, and finally prints or prints the designed refractive layer on the laminated card, and obtains a smart card of a preset shape and size after cutting. The implementation cost of the present invention is low, there is no need to buy special software for dot design, the effect is novel, it can meet more personalized needs, it is not easy to forge, and has a certain anti-counterfeiting effect.

[0024] In order to achieve the third purpose mentioned above, the present invention provides a method for manufacturing a smart card that uses dots to achieve a 3D depth of field perception, which includes the following steps: making a dot layer, including: designing cells composed of second dots, arranging the cells horizontally and vertically, the spacing between adjacent cells is a third preset value, and then cutting according to actual needs, and printing the cut shape on the lower surface of the lower printed substrate; designing a refractive layer, including: arranging first dots of a diameter of a first preset value horizontally and vertically, the center distance between adjacent first dots is a second preset value, and then rotating a preset angle, cutting according to actual needs to obtain a first dot pattern; binding an upper coating, an upper printing substrate, an intermediate substrate, a lower printing substrate, and a lower coating, and laminating them using a laminator to obtain a laminated card; when using the laminator for lamination, a groove corresponding to the first dot pattern is provided on the laminating steel plate corresponding to the upper coating; cutting the laminated card to obtain a smart card of a preset shape.

[0025] As can be seen from the above scheme, the present invention makes a dot layer, prints the dot layer on the lower surface of the lower printed electrode plate, and laminates it based on a laminated steel plate with a certain groove, so that when the other components of the card base are laminated to obtain a laminated card, a refractive layer with a transparent original pattern can be directly formed on the laminated card, and finally a smart card of a preset shape is obtained by cutting. On the basis of realizing the production of a smart card with a 3D effect, the present invention directly realizes the refractive layer by lamination based on a specific laminated steel plate, which is easy to implement.

[0033] The smart card using dots to achieve 3D depth of field perception of the present invention achieves the effect of 3D depth of field perception on the smart card through a low-cost dot pattern. The present invention also provides a method for manufacturing the smart card.

[0034] Smart card implementation using dots to achieve 3D depth of field perception:

[0035] See also Figure 1 The smart card for realizing 3D depth of field perception by using dots in this embodiment includes a card base, and the card base includes a refractive layer 1, an upper coating 2, an upper printed substrate 3, an intermediate substrate 4, a lower printed substrate 5, a dot layer 6, and a lower coating 7 which are arranged in sequence.

[0036] The refractive layer 1 is arranged above the upper printed substrate 3, the upper printed substrate 3 is arranged above the middle layer substrate 4, the lower printed substrate 5 is arranged below the middle layer substrate 4, and the dot layer 6 is arranged on the lower surface of the lower printed substrate 5. The upper coating 2 is arranged between the refractive layer 1 and the upper printed substrate 3, and the lower coating 7 is arranged below the lower printed substrate 5. The lower surface of the lower printed substrate 5 is the surface of the lower printed substrate 5 close to the lower coating 7.

[0037] The card base is made of a clear material with a transparent look and feel, and has an opaque printing ink on it.

[0038] The refractive layer 1 is provided with a first dot pattern, and the dot layer 6 is provided with a second dot pattern. The screen angles of the first dot pattern and the second dot pattern differ by a preset angle. In this embodiment, the preset angle of the screen angle difference is 45°. In other embodiments, it can also be other preset angles. The first dot pattern includes a plurality of first dots, and the second dot pattern includes a plurality of second dots. The refractive layer 1 can be realized by various methods such as lamination, printing with transparent materials such as varnish, etc.

[0039] The upper printing substrate 3 and the lower printing substrate 5 can be provided with printing contents of specific text or specific patterns according to actual card making requirements. In this embodiment, the printing contents on the upper printing substrate 3 are the same as the appearance of the first dot pattern on the refractive layer 1. The second dot pattern of the lower printing substrate 5 needs to be arranged according to specific rules and is produced by four-color printing.

[0040] In other embodiments, the upper printing substrate 3, the middle layer substrate 4 and the lower printing substrate may be the same substrate.

[0041] A first embodiment of a method for manufacturing a smart card using dots to achieve 3D depth of field perception:

[0042] See also Figure 2 , implementing this embodiment includes the following steps:

[0043] S11: Make a dot layer.

[0044] The method includes: designing cells composed of second dots, arranging the cells horizontally and vertically, with the spacing between adjacent cells being a third preset value, and then cutting according to actual needs, and printing the cut shape on the lower surface of the lower printed substrate.

[0045] In this embodiment, see Figure 3 , design the square cells composed of the second dots, the square cells are composed of 11*11 second dots, the diameters of the second dots in the square cells increase from the outer circle to the inner circle, which are 0.15, 0.16, 0.17, 0.18, 0.19, 0.20 mm, and determine the color of the square cells. Figure 4 , arrange the adjacent square cells horizontally and vertically with a spacing of 0.15mm until the entire card is covered. Then, cut out the printed shape according to actual needs, and use an offset printing machine to print on the lower surface of the lower printing substrate using a four-color mirror image. During the printing process of the lower printing substrate, the printed content includes glue, a four-color dot pattern (the second dot pattern), white ink, and a customized pattern or customized text.

[0046] In other embodiments, the cell may also be a cell in a diamond shape, a star shape, a heart shape, or the like.

[0047] S12: Bind the upper coating, the upper printed substrate, the middle substrate, the lower printed substrate, and the lower coating and laminate them using a laminator to obtain a laminated card.

[0048] Among them, the lamination parameters are temperature 150°C and cold pressing time 22 minutes.

[0049] S13: Design the refraction layer.

[0050] Among them, it includes: first dots with a diameter of a first preset value are arranged horizontally and vertically, the center distance of adjacent first dots is a second preset value, and then rotated by a preset angle, cut according to actual needs, to obtain a first dot pattern.

[0051] In this embodiment, see Figure 5 , using a first dot with a diameter of 0.22 mm, the center distance between two adjacent first dots is 0.3 mm, and the first dots are arranged horizontally and vertically according to actual needs to obtain an arrangement diagram of the first dots. Then, after rotating the arrangement diagram of the first dots by 45°, it is cut according to actual needs, for example, the shape is cut according to the printed content of the upper printing substrate to obtain a first dot pattern.

[0052] Without rotating the arrangement diagram of the first dots, the transparent dots (first dots) of the refractive layer can correspond completely one to one with the four-color dots (second dots) of the dot layer.

[0053] S14: Printing or imprinting the refractive layer on the laminated card.

[0054] In this embodiment, an embossing machine or a UV screen printer is used to print the first dot pattern on a laminated card to obtain a refractive layer. The pattern height of the first dots on the refractive layer ranges from 0.1 to 0.18 mm.

[0055] The transparent first dots of the refractive layer can be seen as small lenses. When not rotated, a first dot simply magnifies a corresponding second dot below, and cannot take into account other dots around the second dot. When changing the angle of observation, the depth of field effect cannot be observed, that is, when the observation angle changes, the four-color dots of the bottom layer have almost no visual change. After rotating 45°, the one-to-one correspondence between the first dots of the refractive layer and the second dots of the dot layer is disrupted, and the first dot can take into account multiple second dots. When changing the angle of observation, it can be clearly felt that the second dot pattern moves and changes with the observation angle, which can obtain a better visual 3D effect.

[0056] S15: Cutting the laminated card to obtain a smart card of a preset shape.

[0057] The laminated card can be cut according to the size of the smart card to produce a smart card with a 3D depth of field.

[0058] The above steps S12 and S13 can be swapped according to actual conditions.

[0059] Second embodiment of a method for manufacturing a smart card using dots to achieve 3D depth of field perception:

[0060] In this embodiment, the refractive layer is set synchronously during lamination. Figure 6 , including the following steps:

[0061] S21: Make a dot layer.

[0062] S22: Design the refraction layer.

[0063] S23: Bind the upper coating, the upper printing substrate, the middle substrate, the lower printing substrate, and the lower coating and laminate them using a laminator to obtain a laminated card.

[0064] When laminating using a laminator, a groove corresponding to the first dot pattern is provided on the laminating steel plate corresponding to the upper coating, so that a refractive layer is realized on the laminating card after laminating using the laminator.

[0065] S24: cutting the laminated card to obtain a smart card of a preset shape.

[0066] The above steps S21 and S22 can be swapped according to actual conditions.

[0067] In summary, the smart card using dots to achieve 3D depth of field perception of the present invention achieves 3D depth of field perception, has low cost, solves the problem that the existing smart card surface elements are single and easy to imitate, and can meet more personalized requirements and make the smart card have better anti-counterfeiting characteristics. The method for making a smart card using dots to achieve 3D depth of field perception of the present invention is easy to implement and has novel effects.
