Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of transfer plates, and particularly relates to a refractive multi-layer anti-counterfeiting mold and a transfer plate assembly. Background Art
[0002] In the related art, transfer refers to the process of transferring the pattern on a mold onto a printing substrate such as paper, cardboard, fabric, coated materials, etc. by means of hot stamping or the like. In the prior art, there is a special pattern on the market to achieve anti-counterfeiting. This pattern is composed of a base map for reflecting light and a main map that can observe different images at the same position from different angles. However, the anti-counterfeiting pattern on the printing substrate has limited light reflection ability, resulting in low recognition of the printing substrate, and thus poor anti-counterfeiting effect of the printing substrate. Summary of the Utility Model
[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the utility model is to provide a refractive multi-layer anti-counterfeiting mold. The refractive multi-layer anti-counterfeiting mold designed according to the utility model realizes a wider light reflection angle at the free end of the printing protrusion of the printing substrate and a wider light reflection angle at the connection between the printing protrusion and the printing groove, so that the printing substrate can form a multiple refraction effect in the same area, improving the recognition of the printing substrate and thus enhancing the anti-counterfeiting effect of the printing substrate.

The connecting portion is connected to the bottom of the transfer groove, and the gradient portion is arranged at the free end of the connecting portion; wherein the width of the gradient portion gradually decreases in the direction towards the connecting portion, and / or the width of the connecting portion gradually increases in the direction away from the gradient portion.

Thus, the printing substrate can form a multiple refraction effect in the same area. When light passes through these transfer protrusions, due to the different widths and heights of the transfer protrusions, the light will be refracted and reflected, forming a complex light path, improving the recognition of the printing substrate and increasing the difficulty of counterfeiting.

[0011] Further, the distance between the first side surface and the second side surface is L1, satisfying: 0.7 mm ≤ L1 ≤ 1 mm.

Since the transfer plate assembly according to the present invention is provided with the refractive multi-layer anti-counterfeiting mold of the above embodiment, the anti-counterfeiting effect of the printed matter transferred by the transfer plate assembly is better.

[0031] Embodiment 1:
[0032] As Figures 1 - 4 shown, the present utility model provides a refractive multi-layer anti-counterfeiting mold 1, including: a substrate 10, a transfer groove 11 is provided on the surface of the substrate 10, and a plurality of transfer protrusions 12 are provided in the transfer groove 11. The transfer protrusions 12 include: a connecting portion 121 and a gradient portion 122. The connecting portion 121 is connected to the bottom of the transfer groove 11, and the gradient portion 122 is provided at the free end of the connecting portion 121; wherein the width of the gradient portion 122 gradually decreases in the direction towards the connecting portion 121, and / or the width of the connecting portion 121 gradually increases in the direction away from the gradient portion 122.
[0033] A transfer groove 11 that is recessed towards the inside of the substrate 10 is provided on the surface of the substrate 10, and a plurality of transfer protrusions 12 are provided in the transfer groove 11. Each transfer protrusion 12 includes a connecting portion 121 and a gradient portion 122, and the gradient portion 122 is connected to the bottom of the transfer groove 11 through the connecting portion 121.
[0034] It can be understood that the substrate is extruded in cooperation with the mold 1 to form a specific pattern. The substrate can be a gilding paper, tinfoil paper, paper, cardboard, fabric, coated material or other materials, etc., which is not limited here. After the substrate is cooperated with the mold 1, the transfer protrusions 12 on the mold 1 will form printing grooves on the substrate, and the grooves on the mold 1 (the grooves are defined between two adjacent transfer protrusions 12) will form printing protrusions on the substrate.
[0035] In some embodiments, the width of the gradient portion 122 gradually decreases in the direction towards the connecting portion 121, so that the bottom of the printing groove of the substrate presents a form where the width is smaller as the depth is deeper. Compared with the way that the printing protrusion and the printing groove are in a right-angle fit, the above setting makes the transition between the printing protrusion and the printing groove smooth, and the reflection angle at the connection between the printing protrusion and the printing groove is wider, so that the refraction effect of the substrate on light is better, and the anti-counterfeiting ability of the substrate is improved.
[0036] In other embodiments, the width of the connecting portion 121 gradually increases in the direction away from the gradient portion 122, so that the free end of the printing protrusion of the substrate presents a form where the width is smaller as the height is higher. Compared with the way that the side surface of the printing protrusion and the end surface of the free end of the printing protrusion are in a right-angle fit, the above setting makes the reflection angle of the free end of the printing protrusion wider, so that the refraction effect of the substrate on light is better, and the anti-counterfeiting ability of the substrate is improved.
[0037] In still other embodiments, the width of the gradient portion 122 gradually decreases in the direction towards the connecting portion 121, and the width of the connecting portion 121 gradually increases in the direction away from the gradient portion 122. Thus, through the above setting, the reflection angle at the connection between the printing protrusion and the printing groove is wider, and the reflection angle of the free end of the printing protrusion is wider, so that the refraction effect of the substrate on light is better, and the anti-counterfeiting ability of the substrate is improved.
[0038] Thus, through the above setting, the substrate can form a multiple refraction effect in the same area. When light passes through these transfer protrusions 12, due to the different widths and heights of the transfer protrusions 12, the light will be refracted and reflected, forming a complex light path, which increases the difficulty of counterfeiting.
[0039] According to the refractive multi-layer anti-counterfeiting mold 1 of the present utility model, by making the width of the gradient part 122 gradually decrease in the direction towards the connecting part 121, and / or making the width of the connecting part 121 gradually increase in the direction away from the gradient part 122, a wider reflection angle of the free end of the printing protrusion on the substrate is achieved, and a wider reflection angle at the connection between the printing protrusion and the printing groove is also achieved. Thus, the substrate can form a multiple refraction effect in the same area. When light passes through these transfer protrusions 12, due to the different widths and heights of the transfer protrusions 12, the light will be refracted and reflected, forming a complex light path, improving the recognition rate of the substrate and increasing the difficulty of forgery.
[0040] Embodiment 2:
[0041] Based on Embodiment 1, in this embodiment, the height dimension of the connecting part 121 is h1, and the height dimension of the gradient part 122 is h2, satisfying: 0.6 ≤ h1 / h2 ≤ 0.9.
[0042] It can be understood that when the height h1 of the connecting part 121 is relatively low with respect to the height h2 of the gradient part 122 (the ratio is close to 0.6), the height ratio of the gradient part 122 at the free end of the printing protrusion on the substrate is small, making the reflection angle of the free end of the printing protrusion wider, so that the refraction and reflection effects generated by the free end of the printing protrusion at different angles are better, improving the recognition rate of the substrate.
[0043] When the height h1 of the connecting part 121 is relatively high with respect to the height h2 of the gradient part 122 (the ratio is close to 0.9), the height ratio of the gradient part 122 at the bottom of the printing protrusion is relatively large, making the reflection angle at the connection between the printing protrusion and the printing groove wider, so that the refraction and reflection effects generated by the bottom of the printing protrusion at different angles are better, improving the recognition rate of the substrate.
[0044] Thus, when 0.6 ≤ h1 / h2 ≤ 0.9, the reflection angles of the bottom and the free end of the printing protrusion are both relatively wide, making the overall refraction and reflection effects of the printing protrusion on light better, and improving the recognition rate of the substrate.
[0045] In some embodiments, the two side surfaces of the gradient part 122 in the width direction are the first side surface and the second side surface, and a first transition surface is provided between the end surface of the free end of the gradient part 122 and the first side surface and / or the second side surface, and the first transition surface is configured as an arc surface.
[0046] It can be understood that the first transition surface is configured as an arc surface, so that the light reflection area of the first transition surface is larger, thereby making the refraction and reflection angles of the first transition surface for light larger, and further making the refraction and reflection effects of the first transition surface for light better. Thus, through the above settings, the refraction and reflection effects of the bottom of the printing protrusion of the printing substrate on light are better, improving the recognition rate of the printing substrate.
[0047] Preferably, the two side surfaces of the connecting portion 121 in the width direction are respectively the third side surface and the fourth side surface. A second transition surface is provided between the bottom of the transfer groove 11 and the third side surface and / or the fourth side surface. The second transition surface is configured as an arc surface. Thus, through the above settings, the refraction and reflection effects of the free end of the printing protrusion of the printing substrate on light are better, improving the recognition rate of the printing substrate.
[0048] Embodiment Three:
[0049] Based on Embodiment Two in this embodiment, the distance L1 between the first side surface and the second side surface satisfies: 0.7 mm ≤ L1 ≤ 1 mm. It can be understood that by restricting the distance between the first side surface and the second side surface to be between 0.7 mm and 1 mm, the width dimension of the printing groove formed on the printing substrate is between 0.7 mm and 1 mm, so that the reflected light of the printing grooves affects each other greatly. Furthermore, when finally observing the same position from different angles, since the amount of light reflected from this position to each angle is different, different patterns can be observed in this way.
[0050] According to some embodiments of the present invention, the distance L2 between two adjacent transfer protrusions 12 satisfies: 0.7 mm ≤ L2 ≤ 1 mm. It can be understood that by restricting the distance between two adjacent transfer protrusions 12 to be between 0.7 mm and 1 mm, the width dimension of the printing protrusions formed on the printing substrate is between 0.7 mm and 1 mm, so that the reflected light of the printing protrusions affects each other greatly. Furthermore, when finally observing the same position from different angles, since the amount of light reflected from this position to each angle is different, different patterns can be observed in this way.
[0051] Embodiment Four:
[0052] Based on Embodiment Three in this embodiment, the transfer groove 11 includes: a first transfer area 111 and a second transfer area 112. Transfer protrusions 12 are provided in the second transfer area 112; among them, there are multiple first transfer areas 111, and one of the first transfer areas 111 is arranged around at least part of the outer periphery of the second transfer area 112, and the remaining first transfer areas 111 are arranged at intervals in the second transfer area 112.
[0053] It can be understood that the first transfer area 111 can be used to form the background or frame of the anti-counterfeiting mark. One first transfer area 111 surrounds at least part of the periphery of the second transfer area 112, so that a contour or border can be formed. The second transfer area 112 is provided with transfer protrusions 12 for forming the core pattern or text of the anti-counterfeiting mark. By arranging a plurality of first transfer areas 111 at intervals within the second transfer area 112, that is, the plurality of first transfer areas 111 cooperate with the second transfer area 112 to form a complex pattern combination to form an anti-counterfeiting mark of a specific shape, so as to meet the different needs of different customers.
[0054] According to some embodiments of the present invention, the shape of the first transfer area 111 located within the second transfer area 112 is a letter, a number, a geometric shape, etc. It can be understood that the shapes of the plurality of first transfer areas 111 can be letters, numbers, geometric shapes, etc. respectively, and these shapes can be used alone or in combination to form a complex pattern combination.
[0055] It is worth noting that the letter: can be a single letter or a word, used to represent a brand, a model or other important information; the number: can be a serial number, a date or other numerical information; the geometric shape: can be a simple graph such as a circle, a square, a triangle, etc., or a more complex pattern.
[0056] Embodiment Five:
[0057] As Figure 1 shown, the present invention provides a transfer plate assembly. The transfer plate assembly includes: a transfer plate; a mold 1, and the mold 1 is detachably arranged on the surface of the transfer plate. The mold 1 is configured as the refractive multi-layer anti-counterfeiting mold 1 described in any one of the above embodiments. Since the transfer plate assembly according to the present invention is provided with the refractive multi-layer anti-counterfeiting mold 1 of the above embodiment, the anti-counterfeiting effect of the printed matter transferred by this transfer plate assembly is better.
[0058] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive.
