Description

Technical Field

[0001] This application relates to the field of label technology, and in particular to a structural optical variable label. Background Technology

[0002] In the existing technology, in order to meet the increasing demand for anti-counterfeiting, various identification marks that can be identified by the naked eye have been developed. One such method is to use halftone dots or specially adjusted colors as identification marks. It mainly uses a combination of specific colors and halftone dots as identification basis to carry out anti-counterfeiting treatment for specific products.

[0003] Furthermore, for general letterpress and offset printing, the difference in ink layer stacking height is not noticeable to the naked eye. If the depth of the printed color is to be changed, halftone dots or specially mixed colors are usually used to change the depth of the color. Taking halftone dots as an example, in order to present the depth of the color, halftone dots must be used to present the light color, and the ink layer stacking height is the same, so the color is consistent from the front and the side with no difference in depth.

[0004] However, using halftone dots has many drawbacks in plate-making technology. When using halftone dots or adjusting features to change the depth of color, multiple colors and densities of halftone dots are required to present the changes in light and dark colors, which is very labor-intensive and costly.

[0005] In practical applications, existing technologies, regardless of whether random textures or halftone color combinations are used as anti-counterfeiting identification methods, have the following drawbacks: Because these textures and halftone color combinations are usually very complex, consumers face difficulties in identification during comparison. For example, consumers of different ages may have poorer eyesight, leading to misjudgments. These types of markings are not only inconvenient for consumers to identify, but the identification process is also slow and cannot guarantee good accuracy. Utility Model Content

[0006] This application provides a structured optical variable label, particularly a structured optical variable label formed by printing an information layer consisting of geometric sub-units having different or the same size, shape, and color onto a carrier; this design not only facilitates anti-counterfeiting identification and comparison for consumers, but also increases the difficulty for others to counterfeit it.

[0007] This application utilizes the height difference between the ink layers of the first and second structures to create a technical effect where the same ink layer appears as different colors to the naked eye. Specifically, ink layers stacked higher appear darker, while those stacked lower appear lighter. Furthermore, the information area and background area in the information layer are composed of geometric sub-units such as straight lines, curved lines, wavy lines, triangles, and circles, and the addition of color variations results in a wide variety of image variations created by the combination of the information area and background area. The technical effect of this application is that when the information layer is viewed at an angle, only the top of the ink layer is visible, thus achieving a color difference between the information layer viewed at an angle and the information layer viewed from above, providing an anti-counterfeiting effect.

[0008] To achieve the aforementioned objectives, this application provides a structured optically variable label for direct identification by the user's eyes or touch, comprising: a carrier and a message layer. The message layer is printed on the aforementioned carrier and includes a message area and a background area. The message area has a first structure, which is composed of multiple geometric sub-units; the background area has a second structure, which is composed of multiple second geometric sub-units. The heights of the first structure and the second structure are different.

[0009] In practice, the carrier is a printable carrier.

[0010] In practice, at least one of the first geometric sub-unit and the second geometric sub-unit is polygonal.

[0011] In practice, at least one of the first geometric sub-unit and the second geometric sub-unit is square, circular, triangular, star-shaped, or heart-shaped.

[0012] In practice, at least one of the first geometric sub-unit and the second geometric sub-unit is a straight line or a curve.

[0013] During implementation, the color of the first structure is the same as the color of the second structure.

[0014] In practice, the plurality of first geometric sub-units are divided into at least two groups, and the heights of the groups are different.

[0015] In practice, as described in claim 1 of the structural optical variable tag, the plurality of second geometric sub-units are divided into at least two groups, each group having a different height.

[0016] When implemented, the message area or the background area includes at least one of pattern messages and character messages.

[0017] In practice, each of the plurality of first geometric sub-units constituting the first structure has the same color, and each of the plurality of second geometric sub-units constituting the second structure has the same color.

[0018] In practice, both the first structure and the second structure are made of the same type of ink.

[0033] Please refer to Figure 1 and Figure 2 This application provides a structured optical variable tag for users to identify directly by sight or touch, including: carrier 1 and message layer 2.

[0034] In another embodiment, the carrier 1 is a printable carrier.

[0035] In another embodiment, the printable carrier is selected from the group consisting of: metal carriers, paper carriers, ceramic carriers, plastic carriers, and wood carriers.

[0036] In another embodiment, the printable carrier is a label, bottle, cardboard box, plastic box, paper, or lid.

[0037] Please continue to refer to this. Figure 1 and Figure 2 In this embodiment, the message layer 2 is printed on the aforementioned carrier 1, and the message layer 2 includes a message area 21 and a background area 22. The message area 21 has a first structure 211, which is composed of a plurality of first geometric sub-units 2111. The background area 22 has a second structure 221, which is composed of a plurality of second geometric sub-units 2211. In this embodiment, the message area 21 is the letter "S" composed of first geometric sub-units in the shape of straight rectangles from a top view angle. In other embodiments, the message area includes at least one of patterned information and character information, both of which are within the scope of this application. In this embodiment, the height of the first structure 211 is different from the height of the second structure 221. In other embodiments, the height of the first structure 211 and the height of the second structure 221 may also be the same, both of which are within the scope of this application.

[0038] Please continue to refer to this. Figure 1 and Figure 2 In this embodiment, the present application utilizes the height difference between the first structure 211 and the second structure 221 to create a visual effect where the ink layer three-dimensional structures (first structure 211 and second structure 221) of the same ink raw material color appear to have different colors to the naked eye. For example, when the height of the first structure 211 is higher than the height of the second structure 221, the taller ink layer three-dimensional stack structure (first structure 211) appears darker, and the shorter ink layer three-dimensional stack structure (second structure 221) appears lighter. Furthermore, in this embodiment, the second structure 221 is composed of second geometric sub-units 2211 that are rectangular in shape when viewed from above, meaning that the background area 22 includes an image composed of blank spaces between rectangular straight lines. Please refer to... Figure 2When the information layer 2 is viewed from a tilted or other non-top-down angle, due to the height difference between the first structure 211 and the second structure 221, only the top of the ink layer of the first structure 211 is visible. This creates a different visual effect compared to viewing the information layer 2 from a top-down perspective. For example, the color of the information layer when viewed from a tilted angle differs from the color when viewed from a top-down perspective, providing an anti-counterfeiting effect. In this embodiment, the ink raw material color of the first structure 211 is the same as that of the second structure 221. Of course, in other embodiments, the colors of the first structure 211 and the second structure 221 can be different, allowing for more variations in the anti-counterfeiting identification effect of the information layer 2. Furthermore, in other embodiments, both the first structure and the second structure are made of the same ink, enabling the fabrication of the structured optically variable label of this application using the same ink in a single process.

[0039] In another embodiment, a computer equipped with database software can be used to control a multi-color digital inkjet printer to print at least one of a set of anti-counterfeiting identification patterns and text onto the message area of ​​the carrier 1 by printing method (e.g., inkjet printing). Regarding the content of the message area, in addition to Arabic numerals (1 to 9) and English letters (A to Z), letters of other languages ​​(such as European alphabets, Southeast Asian alphabets, Chinese characters, or phonetic symbols) or various symbols can also be used; it can also be various patterns, such as trademarks; or at least one of pattern information and character information, all of which fall within the scope of this application. Similarly, the background area 22 can also include at least one of pattern information and character information, all of which are within the scope of this application.

[0040] In another embodiment, at least one of the first geometric sub-unit 2111 and the second geometric sub-unit 2211 is polygonal. In another embodiment, at least one of the first geometric sub-unit 2111 and the second geometric sub-unit 2211 is square, circular, triangular, star-shaped, or heart-shaped.

[0041] Please refer to Figure 3 and Figure 4 In one embodiment, each of the first geometric sub-units 2111 is a triangular ink layer when viewed from above, while the second geometric sub-unit 2211 is rectangular when viewed from above. (From reference...) Figure 4 As can be seen from the side view, in this embodiment, the height of the first structure 2111 is also higher than that of the second structure 2211.

[0042] In another embodiment, at least one of the first geometric sub-unit 2111 and the second geometric sub-unit 2211 is a straight line or a curve. For example, at least one of the first geometric sub-unit 2111 and the second geometric sub-unit 2211 may be wavy, curved, straight, irregular, etc., all of which are within the scope of this application.

[0043] In other embodiments, the sub-units constituting each character in the message layer 211 or background layer 221 are of the same shape and can be combined with colors to achieve better recognition, for example, the sub-units can be presented in colors such as red, orange, yellow, green, blue, purple, and black. Following this pattern, and combined with character selection, a large number of character groups with anti-counterfeiting effects and easily identifiable to the naked eye can be generated.

[0044] Please refer to Figure 5 and Figure 6 The plurality of first geometric sub-units 2111 are divided into at least two groups, and the heights of the groups are different. Please continue to refer to Figure 5 , Figure 6 The plurality of first geometric sub-units 2111 are divided into three groups X, Y, and Z, wherein the first geometric sub-units 2111 in groups X, Y, and Z each have their own rectangular arrangement direction and their own height when viewed from a top-down angle. Please refer to... Figure 6 In the side view, the height of each of the first geometric sub-units 2111 in group X is greater than that in group Y, and the height of each of the first geometric sub-units 2111 in group Y is greater than that in group Z. When the user touches or views the information layer 2, the groups X, Y, and Z are arranged at an angle.

[0045] In another embodiment, similarly, the plurality of second geometric sub-units 2211 are divided into at least two groups, each group having a different height, which will not be elaborated here. Therefore, by dividing the plurality of first geometric sub-units 2111 or the plurality of second geometric sub-units 2211 into at least two groups with different heights, various different pattern variations can be generated, thereby allowing for more variations in the anti-counterfeiting identification effect of the message layer 2. In another embodiment, similarly, the plurality of first geometric sub-units 2111 or the plurality of second geometric sub-units 2211 can be divided into at least two groups, but each group has the same height; some groups of the plurality of first geometric sub-units 2111 have the same height, while the remaining groups have different heights; or some groups of the plurality of second geometric sub-units 2211 have the same height, while the remaining groups have different heights, etc., all of which are within the scope of this application.

[0046] In another embodiment, each of the plurality of first geometric sub-units 2111 constituting the first structure 211 has the same ink material color, and each of the plurality of second geometric sub-units 2211 constituting the second structure 221 has the same ink material color. In another embodiment, similarly, each of the plurality of first geometric sub-units 2111 constituting the first structure 211 has different ink material colors. In another embodiment, portions of each of the plurality of second geometric sub-units 2211 constituting the second structure 221 have different ink material colors; for example, some first geometric sub-units 2111 are green, and some are red; some second geometric sub-units 2211 are blue, and some are purple, etc. All of the above embodiments are within the scope of this application.

[0047] In other embodiments, the carrier 1 may have a self-adhesive layer (not shown) on its back side for adhesion to the surface of the product. However, in practice, the self-adhesive layer may be replaced with glue or other adhesive substances to achieve the same purpose.

[0048] In other embodiments, a covering layer (not shown in the drawings) may be provided over the message layer 2 to conceal it. In practice, the covering layer may be a scratch-off layer (composed of a scratch-off material) or a peelable layer. This allows the user to easily identify the structured optically variable label for anti-counterfeiting purposes simply by scratching or peeling off the covering layer. In use, the manufacturer can affix the structured optically variable label, made in label form, to the product. After purchasing the product, the consumer can scratch or peel off the covering layer to obtain a set of anti-counterfeiting reference objects. Alternatively, the manufacturer can directly use a portion of the product as a carrier and print the structured optically variable label on it, achieving the same effect.

[0049] In other embodiments, the anti-counterfeiting identification code is obtained by scratching or tearing off the structured optically variable label printed on the carrier. Users can verify the authenticity of the product via a network, such as a telecommunications network, the Internet, or a general network, using various communication devices, such as computers, mobile phones, and landline phones. For example, in one embodiment, when using a telecommunications network, the user first enters the product number of the purchased item, and then obtains relevant information about the anti-counterfeiting identification code, including the type of characters or patterns, character size, and sub-unit shape; or, when using a proprietary QR code sent through a secure channel, the user can then obtain relevant information about the anti-counterfeiting identification code, including the type of characters or patterns, character size, and sub-unit shape, thereby allowing the user to verify the authenticity of the product or service.

[0050] In other embodiments, when a user makes a query using the Internet, after logging into the query webpage and entering the product number, the user can receive characters or images of the product anti-counterfeiting identification code; thereby, the user only needs to compare the two to identify the authenticity of the product or service.

[0051] Therefore, this application has the following advantages:

[0052] 1. This application utilizes the height difference between the ink layers of the first and second structures to create a technical effect where the ink layers of the same ink raw material color appear to the naked eye as different colors, and only a single type of ink is required, making the process extremely simple and cost-effective.

[0053] 2. In this application, the message area and background area in the message layer are composed of geometric sub-units such as straight lines, curved lines, wavy lines, triangles, and circles, respectively, and color variations are added to make the image composed of the combination of the message area and background area in the message layer have a wide variety of variations.

[0054] 3. This application arranges sub-units in a geometric shape into characters and assigns each character a distinguishable size and color, thereby creating a large number of different anti-counterfeiting identification password combinations, which increases the difficulty of counterfeiting.

[0055] 4. This application uses simple geometric shapes combined with character size and color, along with the height variation of the ink layer structure in the message area and background area, as the basis for identification, allowing consumers to identify and compare with the naked eye or touch; it is not only simple and convenient, but also avoids the shortcomings of conventional technology that are prone to misjudgment.

[0056] 5. By dividing the plurality of first geometric sub-units or the plurality of second geometric sub-units into at least two groups with different heights, this application can generate various different pattern changes, thereby allowing for more variations in the anti-counterfeiting identification effect of the message layer 2.

[0057] In conclusion, this application does indeed achieve the intended purpose, providing a structural optical variable label that can be identified by the naked eye and touch, and has the advantages of being simple, fast, and difficult to counterfeit. It has great value for industrial application, and therefore a patent application is filed in accordance with the law.

[0058] It should be understood that this application is not limited to the detailed structure and arrangement of the components proposed in this application. This application can have other embodiments and can be implemented and executed in various ways. The foregoing variations and modifications fall within the scope of this application. It should be understood that the disclosure and definition of this application extends to all alternative combinations of two or more individual features mentioned or apparent in the text and / or drawings. All these different combinations constitute multiple alternative aspects of this application. The embodiments described in this application illustrate the best known mode for implementing this application and will enable those skilled in the art to utilize this application.
