Description

Anti-counterfeiting structure, anti-counterfeiting article and preparation method of anti-counterfeiting structure

Technical Field

The invention relates to the technical field of anti-counterfeiting, in particular to an anti-counterfeiting structure, an anti-counterfeiting article and a preparation method of the anti-counterfeiting structure.

Background

The lines of the anti-counterfeiting graph obtained by engraving gravure have concave-convex handfeel, and other printing technologies cannot achieve the same effect, so that the anti-counterfeiting graph has a certain anti-counterfeiting effect. However, due to the printing characteristics of engraving gravure, most of the prior anti-counterfeiting graphics are multi-color block spliced graphics with larger area, and when the graphics are spliced by the multi-color blocks, seamless connection cannot be realized between lines of two adjacent multi-color block spliced graphics, namely gaps exist between the adjacent spliced graphics, so that the integrity of the anti-counterfeiting graphics is reduced, the sense of high-grade of the anti-counterfeiting graphics cannot be improved, and the integral visual characteristics of the anti-counterfeiting graphics are further reduced.

Disclosure of Invention

The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

To this end, a first aspect of the invention proposes a security structure.

A second aspect of the present invention provides a security article.

The third aspect of the invention provides a method for preparing the anti-counterfeiting structure.

In view of this, there is provided according to a first aspect of the present invention a security structure comprising: a print layer; the printing layer is arranged on the printing layer, the printing layer comprises at least one first layer and at least one second layer, the lines in at least one first layer in all the first layers are connected with the lines in at least one second layer in all the second layers in a non-error manner, the second layer is different from the first layer in visual characteristics, and the visual characteristics comprise at least one of the following: luminescence brightness, thickness, color, gloss, reflectance, and transparency.

The anti-counterfeiting structure comprises a printing layer and a printing layer, wherein the printing layer is printed on the printing layer and comprises at least one first layer and at least one second layer, and at least one line in the first layer is connected with at least one line in the second layer in a non-error manner, namely in a seamless manner. The arrangement makes up the problem that gaps are easy to exist in the existing spliced pictures and texts, improves the integrity of the anti-counterfeiting structure, and enables the anti-counterfeiting structure to be more exquisite. Therefore, the visual effect of the anti-counterfeiting structure can be enhanced, so that the anti-counterfeiting structure is easy to identify and difficult to forge. So that the anti-counterfeiting structure has stronger anti-counterfeiting characteristic when being used for printed matters such as bank notes, securities, notes and the like. Wherein, in this application, the lines of first layer and second layer can not link to each other at partial region, but the lines that link to each other are all error-free concatenation to can not overlap each other between the lines, the pattern that this kind of error-free concatenation formula integrally formed is richer, has multiple colours on a line, has richer visual effect, can make the pattern finer and more complete.

The fact that the visual characteristics of the first layer and the second layer are different means that the first layer and the second layer may have different thicknesses or colors, or different light-emitting brightness, glossiness, reflectivity, transparency, and the like. The different visual characteristics can enable the two seamlessly connected layers to be distinguished, so that the anti-counterfeiting structure has various different visual effects, such as color change, different reflection degrees, reduced transparency, different luminous brightness, different thickness and the like. The thickness of the anti-counterfeiting structure is different, so that the anti-counterfeiting structure can not only observe visual characteristics of the anti-counterfeiting structure through vision, but also sense the bulges of the patterns in the anti-counterfeiting structure through touch sense, and the anti-counterfeiting effect is greatly increased through the concave-convex touch sense. The fine patterns and various different visual characteristics greatly enrich the color effect of the anti-counterfeiting structure, greatly improve the anti-counterfeiting property of the anti-counterfeiting structure, make the anti-counterfeiting structure difficult to forge, and can be rapidly distinguished from copied or printed copied images and texts because the normal copying and printed images and texts cannot ensure seamless connection. In a word, the anti-counterfeiting structure realizes error-free connection or seamless splicing between two different layers, and improves the integrity of the anti-counterfeiting structure.

Preferably, the printed layer may be printed by engraving gravure or/and screen printing or the like.

Detailed Description

In order that the above-recited objects, features and advantages of embodiments of the present invention can be more clearly understood, a further detailed description of embodiments of the present invention will be rendered by reference to the appended drawings and detailed description thereof. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, embodiments of the invention may be practiced otherwise than as described herein, and therefore the scope of the present application is not limited to the specific embodiments disclosed below.

The security device 100 and the method of manufacturing the security device according to some embodiments of the present invention are described below with reference to fig. 1 to 4.

Example 1

As shown in fig. 1 and 2, a security structure 100 according to an embodiment of the first aspect of the present invention includes a print substrate 1 and a print layer 2 disposed on the print substrate 1. The printed layer 2 comprises at least one first layer 22 and at least one second layer 24, wherein lines in at least one first layer 22 of all first layers 22 are error free connected to lines in at least one second layer 24 of all second layers 24, and the second layer 24 is different from the first layer 22 in visual characteristics including at least one of: luminescence brightness, thickness, color, gloss, reflectance, and transparency.

The anti-counterfeiting structure 100 provided by the invention comprises a printing layer 1 and a printing layer 2, wherein the printing layer 2 is printed on the printing layer 1, the printing layer 2 comprises at least one first layer 22 and at least one second layer 24, and at least one line in the first layer 22 and at least one line in the second layer 24 are connected in a non-error manner, namely in a seamless manner. The arrangement overcomes the problem that gaps are easy to exist in the existing spliced pictures and texts, improves the integrity of the anti-counterfeiting structure 100, and enables the anti-counterfeiting structure 100 to be more exquisite. This may enhance the visual effect of the security device 100 such that the security device 100 is easily identifiable and difficult to forge. Thereby enabling the security structure 100 to have stronger security characteristics when used in printed matter such as bank notes, securities, notes, etc. In this application, the lines of the first layer 22 and the second layer 24 may be not connected in a partial area, but all the connected lines are spliced without errors, and the lines cannot overlap with each other, so that the patterns formed by the spliced without errors are richer, and the patterns have multiple colors on one line, enrich the visual effect, and make the patterns finer and complete.

The fact that the first layer 22 and the second layer 24 have different visual characteristics means that the first layer 22 and the second layer 24 may have different thicknesses or colors, or different light-emitting brightness, glossiness, reflectivity, transparency, and the like. Such different visual characteristics allow the two seamlessly joined layers to be distinguished, thereby allowing security device 100 to have a variety of different visual effects, such as color changes, different degrees of reflection, reduced transparency, different brightness, and different thickness. And the thickness is different, so that the anti-counterfeiting structure 100 can not only observe the visual characteristics thereof visually, but also sense the bulges of the patterns in the anti-counterfeiting structure 100 through touch sense, and the anti-counterfeiting effect is greatly increased through the concave-convex touch sense. The fine pattern and various different visual characteristics greatly enrich the color effect of the anti-counterfeiting structure 100, greatly improve the anti-counterfeiting property of the anti-counterfeiting structure 100, make the anti-counterfeiting structure 100 difficult to forge, and can be rapidly distinguished from copied or printed copied graphics because the graphics and texts which are normally copied and printed cannot be ensured to be connected seamlessly. In summary, the anti-counterfeiting structure 100 of the present application achieves error-free connection or seamless splicing between two different layers, and improves the integrity of the anti-counterfeiting structure 100.

Preferably, the printed layer 2 may be printed by engraving gravure or/and screen printing or the like.

In these embodiments, the first image layer 22 is first divided into at least two areas along a preset direction, for example, divided along a left-right direction or divided along an up-down direction, and then the divided partial areas may be subjected to anti-counterfeiting process treatment, so that at least two ink layers with different thicknesses and/or different colors can be formed on the first image layer 22 along the front-back direction or the up-down direction of the printing layer 1. And because the thickness and the colour are different between the different ink layers, when observing this anti-fake structure 100 from different angles, thicker ink layer can produce the shielding phenomenon to adjacent thinner ink layer, and the dark ink layer of colour also can cause the influence to adjacent light ink layer, makes it deepen in visual colour, from this, will show different visual effects when observing this anti-fake structure 100 from different angles, has enriched the colour of this anti-fake structure 100 greatly, has improved the forging degree of difficulty. In addition, because the first layer 22 is processed into a two-layer structure, the lines of the first ink layer 222 and the second ink layer 224 are also connected seamlessly or without errors.

Further, the first ink layer 222 and the second ink layer 224 also have the following differences under the same excitation light source: luminescence brightness, glossiness, reflectance, and transparency. That is, the first ink layer 222 and the second ink layer 224 may be different in terms of light emission brightness, glossiness, reflectivity, transparency, etc. besides different colors and thicknesses, so that the difference between the first ink layer 222 and the second ink layer 224 is more obvious, the color brightness is more abundant, and the whole first image layer 22 is more beautiful.

The excitation light source in the present application is a light source used for identifying authenticity of the anti-counterfeiting structure 100, such as ultraviolet light, sunlight, infrared light, and the like.

In any of the above embodiments, the printed image layer 2 is preferably a color-changeable image layer made of color-changeable ink. Namely, the printed pattern layer 2 is an optically variable ink pattern layer, a magnetically variable ink pattern layer, or the like, which can change visual characteristics by a post process. I.e. the printed layer 2 should be a variable layer, so that the printed layer 2 can be divided into a plurality of layers with different visual properties according to the later anti-counterfeit process.

In any of the above embodiments, as shown in fig. 1 to 3, the printed pattern layer 2 preferably has at least two thicknesses on the printing layer 1, and the minimum thickness of the printed pattern layer 2 is 7 micrometers or more and 13 micrometers or less.

In these embodiments, the thickness of the printed layer 2 is not constant, and the minimum thickness is 7 microns or more and 13 microns or less. The printed pattern layer 2 with different thickness enables the pattern to be uneven, the convex of the pattern can be perceived through touch sense, the thicker part can be used for visually shielding the thinner part, the visual characteristic of the shielded part is invisible, the different parts are shielded from different observation angles, the visual effect of the anti-counterfeiting structure 100 with different angles is enriched, the anti-counterfeiting characteristic of the anti-counterfeiting structure 100 is enriched, the anti-counterfeiting difficulty is increased, and the anti-counterfeiting is more difficult.

Further, the minimum thickness of the printed layer 2 is 10 microns.

In any of the above embodiments, it is preferred that the thickness of the second layer 24 is less than the thickness of the first layer 22, and/or that the second layer 24 is a different color than the first layer 22, as shown in fig. 1 and 2.

In these embodiments, the second layer 24 and the first layer 22 have different colors or thicknesses, so as to form a fine and complete pattern, the different colors can make the color of the anti-counterfeiting structure 100 more colorful, and since the first layer 22 and the second layer 24 are connected without errors, one line can have multiple colors, which are not single color in the past, the different thicknesses can make the pattern surface uneven, the convex of the pattern can be perceived through touch sense, the thicker part can be shielded from the thinner part by using the different thicknesses, the visual characteristics of the shielded part can be invisible, the different parts can be shielded from different observation angles, the visual effects of the anti-counterfeiting structure 100 with different angles can be enriched, the anti-counterfeiting characteristics of the anti-counterfeiting structure 100 are enriched, and the anti-counterfeiting difficulty is increased.

In any of the above embodiments, the predetermined direction of the print-receiving layer 1 is preferably one of the length direction, the width direction and the thickness direction of the print-receiving layer 1, and the other direction of the print-receiving layer 1 is preferably the other one of the length direction, the width direction and the thickness direction of the print-receiving layer 1. That is, the first image layer 22 may form at least two ink layers along one of the length direction, the width direction or the thickness direction of the printing substrate 1, where the two ink layers have different thicknesses and/or colors under the same excitation light source, so that when the images and texts are observed from the preset direction and other directions of the printing substrate 1, different image and text appearances are presented, the color effect of the anti-counterfeiting structure 100 is greatly enriched, and the anti-counterfeiting characteristic of the anti-counterfeiting structure 100 is greatly improved, so that the anti-counterfeiting structure 100 is difficult to forge.

In any of the above embodiments, preferably, as shown in fig. 1 and 2, at least one first ink layer 222 is formed after at least one preset area of the first layer 22 is subjected to a preset anti-counterfeiting process, and an area of the first layer 22 not subjected to the preset anti-counterfeiting process is at least one second ink layer 224, where the preset anti-counterfeiting process includes one of the following steps: light process treatment, heat radiation process treatment, pressurization process treatment, gravity process treatment, electric field process treatment, magnetic field process treatment and air flow process treatment.

In these embodiments, the specified area of the first layer 22 is subjected to a specific anti-counterfeiting process, and at least one first ink layer 222 and at least one untreated second ink layer 224 are formed after the processing. The arrangement makes the treated first ink layer 222 have different appearances compared with the untreated second ink layer 224, so that the color effect of the anti-counterfeiting structure 100 is greatly enriched while the seamless connection of lines of different layers is ensured, and the anti-counterfeiting characteristic of the anti-counterfeiting structure 100 is greatly improved, so that the anti-counterfeiting structure 100 is difficult to forge.

In these embodiments, the printed layer 2 is integrally formed on the printing layer 1, i.e. the entire printed layer 2 is printed at one time, i.e. the ink materials used for the first layer 22 and the second layer 24 are the same. That is, when printing the printing layer 1, the first layer 22 and the second layer 24 are printed on the printing layer 1 at the same time, and at this time, since the ink of the first layer 22 has not been subjected to the anti-counterfeit process, the visual characteristics of the inks of the two layers are the same. And the formation of the first layer 22 and the second layer 24 is different due to the later anti-counterfeiting process. After the first layer 22 is subjected to the anti-counterfeiting process, the visual characteristics of part of the ink of the first layer 22 are changed, so that a first ink layer 222 with different visual characteristics is formed, and the untreated part of the first layer 22 forms a second ink layer 224, so that the same first layer 22 is divided into two ink layers with different colors, thereby ensuring that the visual characteristics of the anti-counterfeiting structure 100 are richer and the counterfeiting difficulty is enhanced.

That is, when printing the printing layer 1, the first layer 22 and the second layer 24 are printed on the printing layer 1 at the same time, and at this time, since the ink of the first layer 22 has not been subjected to the anti-counterfeit process, the visual characteristics of the inks of the two layers are the same. And the formation of the first layer 22 and the second layer 24 is different due to the later anti-counterfeiting process. After the first image layer 22 is subjected to the anti-counterfeiting process, the visual characteristics of part of the ink of the first image layer 22 are changed, so that a first ink layer 222 with different visual characteristics is formed, and the untreated part of the first image layer 22 is formed into a second ink layer 224, so that the same first image layer 22 is divided into two ink layers with different colors, and therefore, the situation of errors in color block splicing is avoided, error-free splicing is realized, the patterns are finer, the visual characteristics of the anti-counterfeiting structure 100 are richer, and the counterfeiting difficulty is enhanced.

In any of the above embodiments, preferably, the at least two layers with different visual characteristics include at least one first layer 22, and the method for manufacturing the security structure further includes:

dividing the first image layer 22 into at least two areas in parallel along the preset direction of the printing layer 1, carrying out preset anti-counterfeiting process treatment on the image layers of partial areas in the at least two areas, and not carrying out preset anti-counterfeiting process treatment on the image layers of partial areas in the at least two areas, so that the first image layer 22 forms at least two ink layers along the preset direction of the printing layer 1, wherein the at least two ink layers comprise a first ink layer 222 and a second ink layer 224 with different thicknesses and/or colors under the same excitation light source, and at an observation angle along the preset direction of the printing layer 1, the first ink layer 222 can form visual shielding for the adjacent second ink layer 224, so that the first image layer 22 can present two different graphic appearances at the observation angle along the preset direction of the printing layer 1 and the observation angle relative to the other direction of the printing layer 1; the preset anti-counterfeiting process treatment comprises one of the following steps: light process treatment, heat radiation process treatment, pressurization process treatment, gravity process treatment, electric field process treatment, magnetic field process treatment and air flow process treatment.

Example two

As shown in fig. 1 and 2, the present embodiment provides a security structure 100, which includes a printing layer 1, and uses engraving gravure to print ink on the printing layer 1 to form a security image (i.e. a printing image layer 2), wherein the thickness of the printing image layer 2 is greater than 10 micrometers. The anti-counterfeiting image comprises an image B (namely a first image layer 22) and an image C (namely a second image layer 24), wherein the printing image layer 2 is printed on the printing layer 1 by adopting a printing material and is used for displaying a pattern printing material layer and displaying a set pattern. The printed layer 2 comprises at least one first layer 22 and at least one second layer 24, and the pattern displayed by the first layer 22 and the pattern displayed by the second layer 24 can be spliced with each other without errors to form an overall pattern of the printed layer 2. In particular, the lines of the first layer 22 are connected to the lines of the second layer 24, so that the overall pattern of the printed layer 2 can appear complete and fine.

In this embodiment, the thickness of the image B is much greater than that of the image C, so that the protrusion of the pattern in the anti-counterfeiting image can be felt by touching, and the anti-counterfeiting image itself has a certain anti-counterfeiting characteristic. The patterns of the image text B and the image text C can be directly perceived to be different in characteristics through vision, and meanwhile, the lines of the image text B and the lines of the image text C can be connected without errors, namely, multiple visual effects can be achieved on the same line, so that the patterns are richer. The visual information is most sensitive to the user, and thus, enabling the lines of the pattern having raised features to have a variety of visual features can greatly increase the security features of the security structure 100. The visual characteristics of the anti-counterfeiting image and text can be one or more of luminous brightness, luminous wavelength, thickness, glossiness, reflectivity and transparency.

In this embodiment, the color of the ink of the graphic B may be changed by an illumination process, as shown in fig. 3, the left side 3 of the line, the right side 4 of the line are the left side portion and the right side portion of one line of the graphic B, and the second line 5 is the cross section of the line of the graphic C. The image-text B is illuminated from the upper right side of the printing layer 1, and as the image-text B has a certain height, the color of the right side 4 of the line changes due to illumination, and the left side 3 of the line is not illuminated, and the color of the left side 3 of the line does not change, so that the left side 3 of the line and the right side 4 of the line belong to different inks. The colors of which are different.

When a user views the security device 100 from the upper right, it is apparent that only the right side 4 of the line is visible and the left side 3 of the line is obscured. The user can only see the color of the right side 4 of the line at this time, unlike what the user would see when viewing the security device 100 from directly above. The ink on the right side 4 of the line can thus be regarded as a barrier layer.

In contrast, when the user views the security device 100 from the top left, the right side 4 of the line cannot be blocked, and the ink layer on the left side 3 of the line can be considered as a barrier layer.

It should be noted that the blocking layer may also be preset at the corresponding position of the graphic B.

When the image B is irradiated with the excitation light source, since the image B includes a plurality of ink layers, the different ink layers have different visual characteristics, such as color change, reflection, luminescence, becoming opaque, etc., when the image B is observed at one observation angle with respect to the print-receiving layer 1. Here, the excitation light source is a light source used for authentication of the security device 100. Such as ultraviolet light, sunlight, infrared light, etc.

The anti-counterfeiting structure provided in the embodiment can enhance the visual effect of the anti-counterfeiting structure, so that the anti-counterfeiting structure is easy to identify and difficult to forge, and has strong anti-counterfeiting characteristics when being used for printed matters such as bank notes, securities, notes and the like.
