Description

Anti-counterfeiting mark, anti-counterfeiting system, texture grain for anti-counterfeiting mark and use method

Technical field

The invention relates to a random texture anti-counterfeiting identification, an anti-counterfeiting system, a texture particle for random texture anti-counterfeiting identification and a use method of a random texture anti-counterfeiting identifier, and belongs to the technical field of texture anti-counterfeiting.

Background technique

Texture anti-counterfeiting technology is an anti-counterfeiting technology that uses the inherent texture features of the material as an anti-counterfeit identification mark. An important feature of using the texture distribution feature pattern for anti-counterfeit identification is that each piece is different. The basic principle is to randomly form a texture. The distribution feature pattern is stored in the cloud database for review. When the recognition is made, the texture distribution feature pattern comparison in the cloud database is called, which is not true.

Among the texture anti-counterfeiting technologies currently used, one is to randomly distribute the texture particles to form a texture distribution, and then use the feature information of the texture distribution as a texture anti-counterfeiting identifier. However, the texture anti-counterfeiting mark has a small structure due to the texture grain formed by the texture, and is easily imitated by a visual image formed by a technique such as printing, printing, etching, etc. when using a public identification means such as photographing by a mobile phone or direct recognition by a human eye, thereby Visual deception is caused to the public identification, which in turn invalidates the anti-counterfeiting effect.

To this end, the inventor of the present patent conceived a solution to use texture anti-counterfeiting technology under public recognition conditions (the human eye directly observes or can only use conventional photographic function equipment, such as a mobile phone to take photos directly after viewing the photo). The textured texture particles are supplemented with specific identification features that cannot be imitated by printing, printing, etching, etc., and the specific identification features need to meet public recognition conditions, so that the counterfeiters use various printing, various printing, and each A low-cost imitation texture distribution feature pattern, such as etching, is immediately discovered as an anti-counterfeit mark, thereby avoiding visual fraud caused by printing, printing, etching, and the like.

However, due to the texture of the grain used to form the texture, its own structure is very small, it is difficult to directly determine whether there are specific identification features on the texture particles by public identification means such as direct or human direct recognition by the human eye, so it is often necessary to use some Auxiliary tools (such as magnifiers, special light sources, etc.) to observe whether the specific particles are carried on the texture particles, but for the public involved in texture anti-counterfeiting, because the auxiliary tools need to match the specific identification features of the texture particles themselves, the public is very It is difficult to accurately select the appropriate auxiliary tools, and these auxiliary tool identifiers are usually not carried around, thus greatly affecting the public participation in the texture anti-counterfeiting technology.

This provides the viewer with a better viewing angle and makes it easier for the recognizer to observe significant color changes.

In a further technical solution, at least one encoding for the random texture anti-counterfeiting identification number is included; the encoding corresponds to the random texture anti-counterfeiting identifier, or the encoding corresponds to the plurality of random texture anti-counterfeiting identifiers, and the encoding technique is used for the random texture. The anti-counterfeiting labels are numbered to provide a corresponding relationship, which facilitates quick identification and comparison when the identification is later, and improves the efficiency of recognition.

In a further technical solution, the carrier is made of a visually colored portion that is different from the textured particles, and the visual color of the bearing surface as the carrier acts as a contrasting color, highlighting the color change of the textured particles.

In a further technical solution, the bearing surface of the carrier is formed with a visual color coating. Preferably, the visual color coating and the texture color portion of the texture particle adopt different colors, so that the visual color coating serves as a contrast color and highlights the texture. The color change of the particles; further preferably, the visual color coating may also form textures, patterns, patterns, etc., which form complex patterns with the textured particles, increasing the difficulty of imitation.

Compared with the prior art, the anti-counterfeiting system using the random texture anti-counterfeiting identifier provided by the present invention includes the random texture anti-counterfeiting identifier described in any one of the above, and storing stored random texture distribution image information and/or storing random texture distribution. a storage module for characteristic information; a random texture distribution feature image information to be identified and/or a random texture distribution feature information to be recognized and a random texture distribution image information and/or a random texture distribution to be stored by the storage module to realize the random texture anti-counterfeit identification to be identified After the feature information is compared and identified, the identifier only needs to observe the vertical texture and the oblique observation of the random texture anti-counterfeit mark to quickly determine whether the random texture anti-counterfeiting mark uses the texture particle with the specific identification feature (ie, whether it is printing, printing, or Visual spoofing caused by etching techniques, etc., without the need for assistive tools to assist in the judgment, thus enabling the rapid identification of specific identification features of texture particles, thereby greatly increasing public participation.

Compared with the prior art, the method for using the random texture anti-counterfeiting identifier provided by the present invention includes:

Obtain random texture distribution image information and/or random texture distribution feature information of the random texture anti-counterfeit identifier, and store and generate random texture distribution image information and/or store random texture distribution feature information. Among them, the connection between the random texture anti-counterfeiting mark and the anti-counterfeit object refers to the cooperation. There are two main forms of establishing the contact: 1. Attach the anti-counterfeit mark to the anti-counterfeit object, which may be attached to the body of the anti-counterfeit object or Attached to the outer packaging of the security object. 2. The identification is directly made on the body of the anti-counterfeit object, that is, the carrier carrying the texture particles is the anti-counterfeit object itself. In this way, the random texture anti-counterfeiting mark and the anti-counterfeit object are used together to achieve the judgment of authenticity of the anti-counterfeit object by the random texture anti-counterfeiting mark.

In a further technical solution, by adding a code for numbering in the random texture anti-counterfeiting identifier, the random texture distribution image information to be identified and/or the random texture distribution feature information to be recognized and the random texture distribution image information and/or the storage may be determined. Or whether the random texture distribution feature information is stored or not, and the code is used for fast positioning and searching, which greatly saves the judgment time and improves the recognition efficiency.

In a further technical solution, it is only required to determine whether the random texture distribution image information to be identified and/or the random texture distribution feature information to be recognized matches the stored random texture distribution image information and/or the stored random texture distribution feature information, or is vertical. Whether the overall visual color formed by observing all the texture particles of the random texture anti-counterfeit identification to be identified in the direction and the overall visual color formed by observing all the texture particles of the random texture anti-counterfeit identification to be recognized by the transformed oblique angle are discernible to the human eye The visual color difference can quickly determine whether the random texture anti-counterfeiting mark to be identified is false; the judgment method is simpler and does not require specific auxiliary tools to assist in judgment, thereby reducing the difficulty of public participation in recognition, thereby greatly improving Public participation.

In a further technical solution, when it is determined that the random texture anti-counterfeiting flag is true, it is only necessary to simultaneously determine the random texture distribution image information to be identified and/or the random texture distribution feature information to be recognized and the storage random texture distribution image information and/or storage. The random texture distribution feature information is consistent, and the overall visual color formed by all the texture particles of the random texture anti-counterfeiting identifier to be recognized in the vertical direction and the overall visual color formed by observing all the texture particles of the random texture anti-counterfeiting identifier to be identified by at least one oblique angle Relatively there is a visual color difference that is discernible to the human eye, and no specific auxiliary tools are needed to assist the judgment, thereby reducing the difficulty of public participation in recognition, thereby greatly increasing the public participation.

In a further technical solution, the stored random texture distribution image information corresponding to the encoded information is sent to the identifier, and the identifier obtains the acquired random texture distribution image information and the acquired information. Comparing the stored random texture distribution image information corresponding to the coding information, increasing the public participation degree, allowing the recognizer to personally identify, thereby effectively avoiding the falsehood of the judgment result and improving the transparency of the recognition.

The present invention also provides a texture particle for a random texture security feature, for each non-contact surface of the texture particle, a first visual image is formed along the vertical direction, and the angle is The circumferential observation of the texture particles forms a second visual image; the vertical direction is a vertical direction with respect to the contact surface, and the inclination angle is an inclination angle formed by a plane perpendicular to the vertical direction; wherein, at least a ratio of an area occupied by a visual color portion in the first visual image is different from a ratio of an area occupied in the second visual image, such that the first visual image and the second visual image exhibit a visual color difference. When viewed in the vertical direction after randomly forming a random texture anti-counterfeit mark on the carrier, a plurality of first visual images may be directly formed; when viewed at an oblique angle, each texture particle may form part of the second visual image. When the number of texture particles is sufficient, the plurality of texture particles may be regarded as forming a plurality of second visual images by a random probability factor; and then the ratio of the area occupied by the at least one visual color portion in the first visual image is in the second The difference in the proportion of the area occupied by the visual color portion in the visual image causes the visual color formed by the first visual image to exhibit a visual difference with the visual color formed by the second visual image, so that when the random texture anti-counterfeiting identifier is viewed from the vertical direction Multiple texture particles with random textures that observe random texture anti-counterfeit logos in oblique directions When the particles are present, they also exhibit a distinct visual color difference that is discernible to the human eye.

The above technical features may be combined in various suitable manners or replaced by equivalent technical features as long as the object of the present invention can be attained.

detailed description

In order to make the objects, the technical solutions and the advantages of the present invention more clearly, the technical solutions of the present invention will be clearly and completely described below. Based on the specific embodiments of the present invention, those skilled in the art will not make creative labors. All other embodiments obtained below are within the scope of the invention.

Before describing the specific embodiments, the directional names appearing in the present invention are first defined as follows:

When the texture particles of the present invention are normally used (ie, the texture particles fall in a free fall and fall on the carrier in the lowest energy state), after falling on the bearing surface of the carrier, the surface in contact with the bearing surface of the carrier is The contact surface, the end surface facing away from the bearing surface is an upper end surface, and the surface except the upper end surface and the contact surface is an outer peripheral surface, wherein the upper end surface and the outer peripheral surface are collectively referred to as a non-contact surface.

The bearing surface can be a horizontal plane and perpendicular to the horizontal plane.

It should be noted that the "vertical angle" and the "tilt angle" mentioned in the present invention are the angles between the observer's line of sight and the random texture anti-counterfeit mark, but the limit of the angle range is not absolute in the present invention. The definition is based on the mathematical definition, but the optical change effect that can be observed is taken as the standard. In the embodiment, the inclination angle is 15 degrees, and those skilled in the art should understand that the exemplary enumeration here is not a limitation on the inclination angle, and the inclination angle may be any inclination under the premise that the object of the present invention can be achieved. angle.

It should be noted here that the principle of human eye recognition color change is: in the normal viewing distance of the human eye, when the visual spacing angle of adjacent different visual color portions is less than 1", the human eye cannot separately identify two. The color part, and only the visual color mixing effect formed by the two color parts is seen. The texture particles provided by the present invention have an overall visual spacing angle of less than 1" when the human eye is recognized at a normal viewing distance. Therefore, the human eye can only see the visual color mixing effect when directly observed.

When the human eye recognizes only the visual color mixing effect, and the color depth of the different color parts is constant, the main factor that determines the color change of the human eye recognition is the proportion of the area occupied by the different color parts.

In summary, when the ratio of the area occupied by the at least one visual color portion in the first visual image and the ratio of the area occupied by the visual color portion in the second visual image, it is certain that the first visual image is presented. There is a certain visual difference between the visual color produced and the visual color presented by the second visual image.

The invention provides a random texture anti-counterfeiting identifier, wherein each non-contact surface of the texture particle is composed of a plurality of or at least two visual color portions, and the visual color portions each have different visual colors; wherein, the plurality of textures The particles are randomly distributed on the carrier such that there is at least one oblique angle above the bearing surface at which the overall visual color formed by the identified textured particles is observed at the oblique angle, and the identification is observed in a vertical direction perpendicular to the bearing surface in the vertical direction. The overall visual color formed by all textured particles presents a visually distinct visual color difference.

Compared with the prior art, the random texture anti-counterfeiting identifier provided by the present invention is compared with the stored random texture distribution information of the random texture anti-counterfeiting identifier to be identified by the identifier when actually used. After the match, the identifier only needs to observe the vertical texture and the oblique observation of the random texture anti-counterfeit mark to be quickly determined whether the random texture anti-counterfeiting mark uses the texture particles having the specific identification feature (ie, whether it is printing, printing, etching, etc.) The visual spoofing of technology is formed, and no auxiliary tools are needed to assist in the judgment, thereby realizing the rapid recognition of the specific recognition features of the texture particles, thereby greatly increasing the public participation.

For the sake of easier understanding, the following describes and describes the specific embodiments.

Embodiment 1

As shown in Figure 9-1, it is an image formed by observing a random texture anti-counterfeiting mark when it is in a vertical state. Vertical here means perpendicular to the bearing surface; as shown in Figure 9-2, it has an inclination angle of 15° ( That is, when the angle between the bearing surface and the line of sight is), the image formed by the random texture security mark is observed at the oblique angle above the bearing surface.

As can be seen from Figures 9-1 and 9-2, a random texture security feature includes:

Carrier 2, the carrier 2 comprises a bearing surface (the bearing surface is the upper surface of the carrier facing the reader in Figure 9-1, preferably the surface is a horizontal surface);

a plurality of texture particles 1, a plurality of texture particles 1 are randomly distributed on the bearing surface;

Wherein each of the textured particles includes at least two visual color portions on the non-contact surface (the first visual color portion 11 and the second visual color portion 12 are shown in FIGS. 9-1 and 9-2), each of which is visual The color portions exhibit respective visual colors such that there is at least one tilt angle above the load bearing surface at which the overall visual color formed by the plurality of textured particles is viewed, and above the load bearing surface is perpendicular to the load The overall visual color formed by viewing the plurality of textured particles in a vertical direction of the surface exhibits a visual color difference that is discernible to the human eye; wherein, for each non-contact surface of the textured particle, viewed in the vertical direction Forming a first visual image, forming a second visual image along the oblique angle and circumferentially about the textured particle, wherein at least one visual color portion occupies an area ratio in the first visual image The proportion of the area occupied in the two visual images is different, such that the first visual image and the second visual image exhibit a visual color difference.

As is clear from FIGS. 9-1 and 9-2, the ratio of the area occupied by the first visual color portion 11 and the second visual color portion 12 varies, wherein the first visual color portion 11 in FIG. 9-2 The proportion of the area occupied is significantly smaller than that of the first visual color portion 11 in FIG. 9-1, and the ratio of the area occupied by the second visual color portion 12 in FIG. 9-2 is compared with that in FIG. 9-1. The proportion of the area occupied by the second visual color portion 12 is significantly increased. According to the above principle, it should be easily understood that since the first visual image is formed by combining the first visual color portion 11 and the second visual color portion 12, and the second The second visual color portion 12 in the visual image obviously occupies more proportion of the visible area, so it can be confirmed that there is a existence between the mixed color visual effect exhibited by the first visual image and the mixed color visual effect exhibited by the second visual image. There are certain visual differences.

Such a random texture anti-counterfeit logo is to randomly spread a plurality of texture particles 1 on a substrate (or an actual textured particle carrier). When viewed in the vertical direction, it can be regarded as directly forming a plurality of dot-like granular texture particles 1 in a color mixing effect, and each of the texture particles 1 exhibits a visual color of the first visual image; Observed at an angle, and when observing the random texture anti-counterfeit mark from an oblique angle above any one of the bearing surfaces, all the faces of the grain of the grain 1 in this direction can be regarded as forming a part of the second visual image, when the number of texture particles 1 is sufficient For a long time, when the random texture identifier is observed from any direction by the random probability factor, all the texture particles 1 can be regarded as forming a plurality of color mixing units, and each color mixing unit presents a second visual image or a second visual image. Visual color; then there is a certain visual difference between the mixed color visual effect exhibited by the first visual image and the mixed color visual effect exhibited by the second visual image, so that when the random texture anti-counterfeiting mark is viewed from the vertical direction When all texture particles are observed with all texture particles of the random texture anti-counterfeit mark along the oblique angle It also presents an obvious visual color difference that can be discerned by the human eye, so that the random texture anti-counterfeiting mark can realize the specific recognition feature of the texture particle 1 quickly without using an auxiliary tool (ie, when viewed from different angles) Significant color changes), thereby greatly increasing public participation.

The random texture anti-counterfeiting mark is used to realize the visual color formed by observing all the texture particles of the anti-counterfeit mark at an oblique angle after random spreading, and the visual color form formed when observing all the texture particles of the anti-counterfeit mark in the vertical direction. The visual color difference that can be discerned by the person; the production is simpler and at the same time easy for the recognizer to recognize.

The random texture anti-counterfeiting identifier is used. In actual use, when the identifier to be identified of the random texture anti-counterfeiting identifier to be identified by the identifier is compared with the stored random texture distribution information, the identifier only needs to be Random texture anti-counterfeiting logo vertical observation and tilt observation can quickly determine whether the random texture anti-counterfeiting label uses texture particles 1 with specific identification features (ie, whether it is a visual fraud caused by printing, printing, etching, etc.), and no longer Auxiliary tools are needed to assist in the judgment, thereby realizing the rapid identification of the specific identification features of the texture particles 1, thereby greatly increasing the public participation.

Texture particles for the random texture identification have features as described above: for each non-contact surface of the texture particles, a first visual image is formed along the vertical direction, along the oblique angle and around the texture The circumferential observation of the particles forms a second visual image; the vertical direction is a vertical direction with respect to the contact surface, and the oblique angle is an inclined angle formed by a plane perpendicular to the vertical direction;

Wherein the ratio of the area occupied by the at least one visual color portion in the first visual image is different from the proportion of the area occupied in the second visual image, such that the first visual image and the second visual image are rendered A visual color difference. In order to ensure the realization of the above-mentioned random texture identification of the beneficial technical effects.

Some representative texture particles 1 are described below.

Embodiment 1:

As shown in FIGS. 1-1 to 1-3, a texture particle 1 for a random texture security feature is provided in FIG. 1-1, and a first visual image of the texture particle 1 is shown in FIG. Viewing the top view of the upper end face vertically), Figure 1-3 shows the second visual image of the texture grain 1 when the angle of inclination is 15° (ie the angle between the bearing surface and the line of sight) (since the second visual image should For a panoramic view, it is difficult to reflect in the drawing, so only four front views are the main view, four The transition diagram between views is represented by a rotated line, but does not hinder the understanding of the present technical solution).

In this embodiment, the upper end surface of the texture particle 1 is composed of a plurality of visual color portions, specifically, the first visual color portion 11, the second visual color portion 12, and the third visual color portion 13; the outer peripheral surfaces of the texture particles 1 are all A visual color portion, specifically a fourth visual color portion 14.

As is clear from FIGS. 1-2 and 1-3, the area ratio of each of the first visual color portion 11, the second visual color portion 12, the third visual color portion 13, and the fourth visual color portion 14 occurs. Variety. According to the above principle, it should be easily understood that since the first visual color portion 11, the second visual color portion 12, and the third visual color portion 13 are mixed into a color in the first visual image, and the fourth visual image is in the fourth visual image. The color portion 14 obviously occupies more of the visible area ratio, so it is certain that there is a certain visual difference between the mixed color visual effect exhibited by the first visual image and the mixed color visual effect exhibited by the second visual image.

Therefore, when the texture grain 1 is made into a random texture anti-counterfeit mark, a plurality of texture particles 1 are randomly scattered on the substrate (or the actual texture particle carrier) to form a random texture anti-counterfeit mark; when viewed in the vertical direction , can be regarded as directly forming a plurality of dot-like granular texture particles 1 in a color mixing effect, and each texture particle 1 exhibits a visual color of the first visual image; viewed at an oblique angle, and when from any direction When observing the random texture anti-counterfeit mark, all the faces of the texture grain 1 facing this direction can be regarded as forming a certain part in the second visual image. When the number of the texture particles 1 is sufficient, the random probability factor is observed from any one direction. When the texture is identified, all the texture particles 1 can be regarded as forming a plurality of color mixing units, and each color mixing unit presents a second visual image or a visual color similar to the second visual image; and then presented by the first visual image There is a certain visual difference between the mixed color visual effect and the mixed color visual effect exhibited by the second visual image, thereby making When viewing all the texture particles of the random texture anti-counterfeit mark in the vertical direction and all the texture particles of the random texture anti-counterfeit mark in the oblique direction, the visual color difference of the human eye can be clearly recognized, thereby making the random texture anti-counterfeiting mark It is possible to quickly identify the specific recognition features of the texture particles 1 (ie, exhibit significant color changes when viewed from different angles) without using auxiliary tools, thereby greatly increasing public participation.

At the same time, with the scheme, the fourth visual color portion can be firstly formed into the fourth visual color portion 14 of the texture particle portion, and then printed and sprayed with the first visual color, the second visual color and the third visual color. The end faces form the first visual color portion 11, the second visual color portion 12, and the third visual color portion 13, thereby facilitating fabrication.

Further, in the present embodiment, before the texture particles 1 are distributed on the bearing surface, the texture particles 1 include upper, lower and outer peripheral sides, and the upper and lower surfaces of the textured particles are composed of various visual color portions, and the outer peripheral side of the textured particles is a visual color component; after the texture particles are distributed on the bearing surface, the outer peripheral side of the textured particle becomes the outer peripheral surface of the textured particle, and the upper or lower surface of the textured particle in contact with the bearing surface becomes the contact surface of the textured particle, and the bearing surface The underside or the top of the textured particles that are not in contact are the upper end faces of the textured particles. In this solution, the body of the textured grain 1 can be firstly formed with a visual color portion, and then printed and sprayed with a plurality of visual color portions to form the upper and lower portions for rapid processing and manufacturing; further, only need to be ensured during use. Texture particle 1 can be used normally. There is no need to distinguish between the upper and lower sides, which facilitates the use of the texture particles 1 and greatly reduces the number of processes.

Further, in this embodiment, the type and the number of the visual color portions on the upper surface of the texture particles 1 are the same as the types and the number of the visual color portions below the texture particles, and the positions are one-to-one correspondence; wherein, the upper surface of the texture particles Each visual color portion extends below the textured particles and forms a through structure. That is, the first visual color portion 11, the second visual color portion 12, and the third visual color portion 13 penetrate from above the texture particles to the lower side. When the structure is adopted, the main body of the textured particle 1 formed by the plurality of visual color portions can be quickly processed by a conventional method such as silking, extruding, etc., and finally a visual portion is roving at the outer peripheral surface (in this embodiment, visual The color portion 14), which is capable of using a relatively conventional production process, reduces production costs and increases production efficiency.

Embodiment 2:

As shown in FIGS. 2-1 to 2-3, a texture particle 1 for a random texture security feature is provided in FIG. 2-1, and a first visual image of the texture particle 1 is shown in FIG. 2-2 (ie, Viewing the top view of the upper end face vertically), Figure 2-3 shows the second visual image of the texture grain 1 when the angle of inclination is 15° (ie the angle between the bearing surface and the line of sight) (since the second visual image should For a panoramic view, it is difficult to carry out the embodiment in the drawing, so only four front views are taken as the main view, and the transition diagram between the four views is represented by a rotating line, but does not hinder the understanding of the technical solution).

In the present embodiment, the upper end surface of the texture particle 1 is composed of a visual color portion, specifically the fifth visual color portion 15, and the outer peripheral surface of the texture particle 1 is composed of a plurality of visual color portions, specifically the first visual color portion 11 a second visual color portion 12, a third visual color portion 13, and a fourth visual color portion 14.

In this embodiment, the principle that there is a certain visual difference between the visual effect presented by the first visual image and the mixed color visual effect exhibited by the second visual image is the same as or similar to that in Embodiment 1. Let me repeat.

In the embodiment, the upper end surface is composed of a visual color portion, and the outer peripheral surface is composed of a plurality of visual color portions, and the texture particles formed by the plurality of visual color portions can be quickly processed by a conventional method such as silking and squeezing. The main body, finally by printing, spraying and other technical means to form a visual color part at the upper end surface, thereby facilitating processing and manufacturing.

Further, in the present embodiment, before the texture particles 1 are distributed on the bearing surface, the texture particles 1 include upper, lower and outer peripheral sides, and the upper surface of the textured particles 1 is composed of a visual color portion, and the underside of the textured particles 1 is a kind The visual color portion is composed, and the outer peripheral side of the texture particle 1 is composed of a plurality of visual color portions. With this scheme, the main body of the texture particle 1 formed by various visual color portions can be quickly processed by a conventional method such as silking and squeezing. Finally, a visual color portion is formed on the upper and lower sides by means of printing, spraying, etc., thereby facilitating the processing and manufacturing; further, it is only necessary to ensure that the texture particles 1 are in a normal use state when used, without further The upper and lower sides are distinguished. After the textured particles 1 are distributed on the bearing surface, the outer peripheral side of the textured particles 1 becomes the outer peripheral surface of the textured particles, and the upper or lower surface of the textured particles in contact with the bearing surface becomes the contact surface of the textured particles. The lower or upper surface of the textured particles that are not in contact with the bearing surface becomes the upper end surface of the textured particles Dispenser texture particles to facilitate the use of 1, greatly reducing the process.

Various embodiments of the above two embodiments describe the texture particles 1 formed by various visual color portions However, in the actual production process, the more the number of visual color parts used, the more complicated the manufacturing process and the higher the cost.

For this reason, it is preferred that the texture particles 1 can be produced by using only two kinds of visual parts to achieve the same technical effect; however, the production difficulty and the production cost are greatly reduced, and the production efficiency is improved.

The texture grain 1 having only two visual color portions will be specifically described below.

Embodiment 3:

As shown in FIGS. 3-1 to 3-3, a texture particle 1 for a random texture security feature is provided in FIG. 3-1, and a first visual image of the texture particle 1 is shown in FIG. 3-2 (ie, Viewing the top view of the upper end face vertically), Figure 3-3 shows the second visual image of the texture grain 1 when the tilt angle is 15° (ie the angle between the bearing surface and the line of sight) (since the second visual image should For a panoramic view, it is difficult to carry out the embodiment in the drawing, so only four front views are taken as the main view, and the transition diagram between the four views is represented by a rotating line, but does not hinder the understanding of the technical solution).

In the present embodiment, all of the upper end faces of the texture particles 1 are the first visual color portion 11, and the first visual color portion 11 extends to the outer peripheral surface of the texture particles 1, and the first visual color is removed from the outer peripheral surface of the texture particles 1. The remaining portion after the portion 11 is the second visual color portion 12.

As is clear from Fig. 3-2 and Fig. 3-3, the ratio of the area occupied by the first visual color portion 11 and the second visual color portion 12 varies. According to the above principle, it should be readily understood that since the first visual color portion 11 is colored in the first visual image, and the second visual color portion 12 in the second visual image clearly occupies more visible area ratio, It is certain that there is a certain visual difference between the visual effect exhibited by the first visual image and the mixed color visual effect exhibited by the second visual image.

Therefore, when the texture grain 1 is made into a random texture anti-counterfeit mark, a plurality of texture particles 1 are randomly scattered on the substrate (or the actual texture particle carrier) to form a random texture anti-counterfeit mark; when viewed in the vertical direction , can be regarded as directly forming a plurality of point-like granular texture particles 1 in the color of the first visual color portion 11 , and each of the texture particles 1 exhibits a visual color of the first visual image; viewed at an oblique angle, and When observing the random texture anti-counterfeit mark from any one direction, all the faces of the texture grain 1 facing this direction can be regarded as forming a certain part in the second visual image. When the number of texture particles 1 is sufficient, the factor of random probability is from When viewing the random texture identifier in any direction, all the texture particles 1 can be regarded as forming a plurality of color mixing units, and each color mixing unit exhibits a second visual image or a visual color similar to the second visual image; There is a certain visual difference between the visual effect exhibited by the image and the mixed color visual effect exhibited by the second visual image. Therefore, when all the texture particles of the random texture anti-counterfeit mark are viewed from the vertical direction and all the texture particles of the random texture anti-counterfeit mark are observed in the oblique direction, the apparent visual color difference of the human eye is also presented, thereby making the species The random texture anti-counterfeiting mark can realize the specific recognition feature of the texture particle 1 (ie, exhibits obvious color change when viewed from different angles) without using the auxiliary tool, thereby greatly increasing the public participation.

At the same time, all of the upper end faces are the first visual color portions 11, and the remaining portions of the outer peripheral surface of the texture particles 1 after removing the first visual color portion 11 are the second visual color portions 12, and the second portion can be used first.

In this embodiment, the visual color portions are two, respectively a first visual color portion 11 and a second visual color portion 12; before the texture particles 1 are sprinkled on the bearing surface, all of the upper surfaces of the texture particles 1 are the first vision. The color portion 11, and the first visual color portion 11 extends to the outer peripheral surface of the texture particle 1, all of the lower surface of the texture particle 1 is the first visual color portion 11, and the first visual color portion 11 extends to the periphery of the texture particle 1.

According to the above principle, it should be readily understood that since the first visual image portion 11 and the second visual color portion 12 are formed in the first visual image, the second visual color portion 12 in the second visual image clearly occupies more The visible area ratio, therefore, it can be confirmed that there is a certain visual difference between the mixed color visual effect exhibited by the first visual image and the mixed color visual effect exhibited by the second visual image.

Therefore, when the texture grain 1 is made into a random texture anti-counterfeit mark, a plurality of texture particles 1 are randomly scattered on the substrate (or the actual texture particle carrier) to form a random texture anti-counterfeit mark; when viewed in the vertical direction , can be regarded as directly forming a plurality of dot-like granular texture particles 1 in a color mixing effect, and each texture particle 1 exhibits a visual color of the first visual image; viewed at an oblique angle, and when from any direction When observing the random texture anti-counterfeit mark, all the faces of the texture grain 1 facing this direction can be regarded as forming a certain part in the second visual image. When the number of the texture particles 1 is sufficient, the random probability factor is observed from any one direction.

In actual use, compared to the texture particle 1 structure in the fourth embodiment, the texture particle 1 structure has a relatively large area occupied by the first visual color portion 11 in the first visual image of the texture particle 1 when viewed vertically. Some, but when viewed obliquely, the proportion of the area occupied by the first visual color portion 11 is significantly reduced, thereby enabling the recognizer to more easily observe the apparent color change.

And in use, the first visual color portion 11 in the first visual image of the texture particle 1 occupies a relatively large area when viewed vertically, but the area ratio of the first visual color portion 11 is significantly reduced when viewed obliquely, so It makes it easier for the recognizer to observe obvious color changes.

Further, in the present embodiment, the first visual color portion 11 corresponds to the position on the upper surface of the texture particle 1 and the lower surface of the texture particle 1, and the first visual color portion 11 extends from the upper surface of the texture particle 1 to the texture particle.
