Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the following description will be made with reference to the accompanying drawings and examples.
It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
As shown in figure 1, the invention provides a manufacturing method of a variable printing anti-fake card, which comprises the following steps:
s1, prefabricating a blank card material;
the prefabricated blank material is formed by pressing the base material layer 1, the laser etching layer 2 and the first transparent protective layer 3 together to form a piece of PC material.
As shown in figure 2, the variable printing anti-fake card manufactured by the method comprises a base material layer 1, a laser etching layer 2, a first transparent protective layer 3, a transparent coating layer 4, an ink layer 5 and a second transparent protective layer 6 which are sequentially laminated. Wherein, the substrate layer 1, the laser etching layer 2 and the first transparent protective layer 3 can be pre-pressed together to form a piece of PC material. Specifically:
substrate layer 1: typically polyvinyl chloride, polycarbonate. For a single-sided anti-counterfeiting card (such as a certain entrance card, etc.), the base material layer 1 is positioned at the bottommost layer of the card, and a laser etching layer 2, a first transparent protective layer 3, a transparent coating 4, an ink layer 5 and a second transparent protective layer 6 can be arranged from bottom to top in sequence; for a double-sided anti-counterfeiting card (such as the front side, the back side and the like of an identity card), the substrate layer 1 is positioned in the middle layer of the card, and the laser etching layer 2, the first transparent protective layer 3, the transparent coating 4, the ink layer 5 and the second transparent protective layer 6 can be sequentially arranged from the middle layer upwards or downwards.
Laser etching layer 2: laser etching is a technique that uses a laser beam to directly evaporate or ablate material from the surface of an object. Etching of the material can be achieved by controlling the laser. The laser etching layer 2 may be formed by adding a material such as carbon to a PC material, and partially pyrolyzing the material when receiving a high-intensity laser beam to form carbide deposited on the etched region, thereby forming a black pattern. These are already prior art and are not described in detail here. Because of the high energy of laser etching, the user identity information is etched in a destructive manner, so that the user identity information obtained by laser etching has the effect of being difficult to tamper with. Simultaneously, when the etching materials are etched by laser, the black effect can be etched perfectly. The laser etching layer 2 is used for etching user identity information in a laser etching mode, and after laser etching, black and white identity information of a user is generated in the card laser etching layer 2, wherein the user identity information comprises image information and character information; wherein, the black-and-white image information comprises the portrait of the user, and the text information comprises the text information such as the name, the certificate number and the like of the user and related to the identity of the user.
A first transparent protective layer 3: typically PC material; the first transparent protective layer 3 is arranged on the laser etching layer 2 of the anti-counterfeiting card, which has the following advantages: durability is improved: the first transparent protective layer 3 can effectively protect the laser etched layer 2 from external environments such as scratches, friction, and erosion of chemical substances. Therefore, the service life of the anti-fake card can be prolonged, and the anti-fake card has better durability. Preventing the etching layer from being damaged by people: the first transparent protective layer 3 can effectively prevent the laser etched layer 2 from being scratched or scraped by a person. Without a transparent protective layer, the laser etched layer 2 may be susceptible to damage, resulting in the security feature being exposed or tampered with. Increasing the optical effect: the transparent protective layer can increase the optical effect of the anti-fake card, such as improving the definition of laser etching patterns, increasing the reflection effect, etc. Therefore, the anti-counterfeiting card can attract eyeballs more, and the identification degree and anti-counterfeiting effect of the anti-counterfeiting card can be improved. Difficult to imitate: the transparent protective layer can increase the complexity of the anti-fake card, so that a counterfeiter is more difficult to copy the identical appearance. The transparent protective layer is made of special materials or processes, so that the imitation difficulty of the anti-counterfeiting card can be further improved, and the anti-counterfeiting performance is improved. Particularly when the substrate is made of a metal material, a relatively smooth surface is often formed after laser etching, and adhesion of ink in a later stage is not facilitated, so that the printing effect is affected.
S2, etching user identity information on the card material on the laser etching layer 2 by utilizing laser according to a first variable;
when the personalized card is manufactured, the laser is used for etching, the laser can penetrate through the transparent protective layer, and the user identity information comprising patterns and characters is formed on the laser etching layer 2. The laser etching layer 2 etches user identity information according to a first variable, wherein the user identity information can comprise all or part of black-white images and text information; the variables may be proportions, regions, or a superposition of proportions and regions.
When the variables are the ratios, at the moment, the first variable is a first ratio, and the first ratio is a set etching ratio when the user identity information is etched by laser; the second variable is the second proportion, and the second proportion is the set melanin printing proportion when the black part information in the user identity information is printed by the ink and the 100% normal printing proportion when the color part information is printed by the ink. At this time, there are several setting modes as follows:
first kind: the first proportion is 100%, namely the etching proportion is set to be 100% when the user identity information is etched by laser; the second ratio is 0, namely, the black pigment printing ratio is set to be 0 when the black part information in the user identity information is printed by ink and the normal printing ratio is set to be 100% when the color part information is printed by ink. At this time, the black part information in the user identity information is the laser etching, and the ink is not printed. During verification, whether the black part information only presents pigment points etched by laser under a microscope is checked, so that identification of a fake card is facilitated.
Second kind: a first ratio of <100%, i.e. the etching ratio is set when the user identity information is laser etched
<100%; the second ratio is >0, namely the set melanin printing ratio when the black part information in the user identity information is printed by ink is >0 and the 100% normal printing ratio when the color part information is printed by ink. For example: the first ratio was 70% and the second ratio was 40%. At this time, if the laser etching is to print 100 pigment dots (100% ratio), and the ratio is reduced to 70% for printing, which means that the printing result will only include 70% of the original pigment dots, then only 70 laser etched pigment dots 7 will be printed in practice, as shown in fig. 3.
When the variable is a region, the first variable is a first region, and the first region is a set etching region for laser etching of user identity information. The laser etching layer 2 of the invention etches the user identity information according to the first variable, wherein the proportion and the area can be set by one card, the proportion and the area are matched with the second variable (proportion and area) to be equal to one card, the image-text reserved file with the original setting state is checked in the cloud server, and the verification module is arranged on the cloud server, so that the pigment proportion and/or the area of the card to be verified can be effectively identified, and the authenticity can be distinguished.
S3, performing a printing process on the etched card, wherein the printing process specifically comprises the following steps:
s31, printing a transparent coating layer 4 on the first transparent protective layer 3;
transparent coating 4: generally, the transparent protective layer is made of resin, and the composition and granularity of the transparent coating layer 4 are modulated according to the material and the surface smoothness of the transparent protective layer, so that the transparent coating layer 4 can be well bonded with the transparent protective layer. The transparent coating 4 can increase the adhesion of ink in the security print. The transparent coating 4 has good adhesiveness and adhesion, and can firmly fix the ink on the surface of the printed matter to prevent the ink from falling off or being damaged. The transparent coating layer 4 is an optional setting layer, and the transparent coating layer 4 may not be set when the transparent protective layer itself has good ink adhesion. By adding specific chemical components to the transparent coating 4, the adhesion of the ink to the surface of the printed matter can be enhanced. These additives may promote interactions between the ink and the printing material, increasing the binding force between them. At the same time, the transparent coating 4 can also fill tiny depressions or uneven parts of the surface of the printed matter, so that the ink can be more uniformly covered on the surface, and the adhesiveness is further increased. Good adhesion of the ink is critical for security prints. The anti-counterfeiting label can ensure that information such as anti-counterfeiting characteristics, patterns, characters and the like cannot be blurred, faded or tampered in the long-time use process. The presence of the transparent coating 4 can effectively improve the adhesion of the ink and increase the durability and security of the security printed matter.
S32, printing user identity information of the ink layer 5 on the transparent coating 4 according to a second variable;
ink layer 5: typical ink printing, commonly known as YMCK color printing mode, represents four color channels: yellow (Yellow), magenta (Magenta), cyan (Cyan), and black (Key). The YMCK printing mode is based on the color superposition principle. By sequentially superimposing the ink cartridges of these four color channels during printing, a rich color effect can be produced. By means of the color superposition mode, the YMCK printing mode can achieve more accurate and rich color printing effects. It is commonly used for printing colour photos, images, business cards, certificates and other occasions where high quality colour output is required. In the spray printing process, the printer sprays four colors of ink according to a certain rule and mode according to the required patterns or characters. Because each spraying is at the same position, the ink dots can be gradually overlapped to form larger and denser pigment dots, and finally the required color effect is displayed.
The invention sets the performance of the printer before printing, sets the color taking mode of the printer as three-color black, wherein the color taking mode of the three-color black is different from the color taking mode of common four-color black, and the color taking mode of the three-color black refers to that the four color channels take M0Y 0C 0K 100 to print. The four-color black color taking mode refers to that four color channels take C75M 68Y 67K 90, and the four colors are black printed by overlapping. When the color taking mode is three-color black, the printed black-white image-text is amplified by a microscope, and only melanin is contained, so that other pigment points can not be doped. The color information in the color text information is the mixed display of normal pigment.
After the setting is completed, color ink is utilized to print color images and character information of user identity information on the transparent coating 4 above the etched black-and-white images and character information according to a second variable, so that the color images and character information and the etched black-and-white images and character information are mutually aligned and overlapped, and a personalized information surface is obtained.
When the variables are ratios, at this time, the second variable is a second ratio, and the second ratio is a set melanin printing ratio when the black part information in the user identity information is printed by the ink and a 100% normal printing ratio when the color part information is printed. At this time, there are several setting modes as follows:
first kind: the first proportion is 100%, namely the etching proportion is set to be 100% when the user identity information is etched by laser; the second ratio is 0, namely, the black pigment printing ratio is set to be 0 when the black part information in the user identity information is printed by ink and the normal printing ratio is set to be 100% when the color part information is printed by ink. At this time, the black part information in the user identity information is the laser etching, and the ink is not printed. During verification, whether the black part information only presents pigment points etched by laser under a microscope is checked, so that identification of a fake card is facilitated.
Second kind: a first ratio of <100%, i.e. the etching ratio is set when the user identity information is laser etched
<100%; the second ratio is >0, namely the set melanin printing ratio when the black part information in the user identity information is printed by ink is >0 and the 100% normal printing ratio when the color part information is printed by ink. For example: the first ratio was 70% and the second ratio was 40%. At this time, if the ink printer is to print 100 pigment dots (100% ratio), the ratio is selected to be reduced to 40% for printing, and then only 40 ink-printed pigment dots 8 are actually printed. And after aligning and overlapping the two printing results, displaying black part information and color part information in the complete user identity information. However, as shown in fig. 4, the black partial pigment dot information may exhibit an orderly coverage overlapping state under a microscope. In practical operation, the sum of the set etching proportion and the set melanin printing proportion can be about 100% (as shown in fig. 5) or more than 100%, so as to ensure the plumpness of the graphic information. In addition, even though the coverage staggering of the pigment points is not perfect complementation under a microscope of a microscopic level, a plurality of staggered overlapping, staggering and blank areas appear, but because the human eyes are opposite to the perception of the colors, the colors can be perceived according to the surrounding colors and the brightness of the light rays, and the visual effect of image printing is not influenced under the human eyes. When the first variable is a first proportion, the first proportion is 100%, namely the etching proportion is set to be 100% when the user identity information is etched by laser; the second ratio is 0, namely, when the black part information in the user identity information is printed by ink, the melanin printing ratio is set to be 0 and the normal printing ratio is set to be 100% when the color part information is printed, and the melanin of the color ink is not sprayed. Other cases are sprayed according to the setting.
When the variable is the area, the second variable is the second area, and the second area is the set melanin printing area when the black part information in the user identity information is printed by the ink and the 100% normal printing area when the color part information is printed by the ink. The set etching area and the set melanin printing area are overlapped to form a black part area in the complete user identity information. Printing color images above the black-and-white images etched by the laser in a mutually overlapping mode by utilizing the color ink, so that the color images and the black-and-white images are mutually aligned and overlapped to obtain a personalized information surface; namely, a color image layer is covered on the black-and-white image, and the color image layer and the black-and-white image are mutually aligned; at this time, the etching of the black part area and the complementary state of each part of the ink are presented under the microscope, and the variable can be set one by one, and the performance of the anti-fake card is improved by matching with the identification and authentication of the cloud server.
When checking false, other pigments with ink in the black part of the user identity information are false (three-color black printing is not adopted), and only the melanin of the ink is false (no laser etching), and the mode of overlapping nesting without overlapping nesting or non-matching overlapping nesting (printing according to a set variable) is also false, wherein the first proportion of the printing condition as a special set variable is 100%, the second proportion is 0, and only the etched melanin is true.
The specific data of the proportion and the area in the variable printing can be set in a one-by-one mode, or can be set according to the date or the time period for examination.
In addition, the verification modules can be combined with the identification aiming at the proportion or the area to verify the difference between the original correct setting mode and the card to be verified so as to identify the authenticity of the card.
S33, printing a second transparent protective layer 6 on the ink layer 5;
in order to increase the durability and the protective effect of the printed matter, a transparent second transparent protective layer 6 is added on the uppermost layer of the printing.
S4, printing a contour anti-counterfeiting mark which is consistent with the contour of the image information of the user on the second transparent protective layer 6 by using optically variable ink.
The outline anti-counterfeiting mark which is consistent with the outline of the image information of the user is printed on the second transparent protective layer 6 by using optically variable ink, and the printed outline anti-counterfeiting mark is framed on the periphery of the image information of the user formed by overlapping laser etching and ink printing.
The anti-counterfeiting card manufactured under the condition of taking the proportion as a variable is taken as an example according to the method of the invention:
as a variable printing anti-fake card manufactured by the method, the laser etching layer 2 is etched with black and white user identity information according to a first proportion variable, namely, the etching of the user identity information is carried out by using the black of a first proportion (100% or other proportion lower than 100% and larger than 0) set by the proportion variable (generally, however, in order to ensure the anti-fake effect of the laser etching, the etching proportion is not set too low); the ink layer 5 prints all black information in the user color identity information according to a second ratio variable, i.e. the black ink is used to print at a second ratio (0 when the first ratio is 100% or other ratios below 100%) set by the ratio variable, while the color information in the other color identity information is printed normally. It should be noted that, to ensure that the appearance effect is more full, the sum of the first proportion and the second proportion needs to be about 100% or more than 100%, for example, the first proportion is set to 70% and the second proportion is set to 40%, and at this time, some blank areas between 70% of the black pigment dots etched by the laser will appear under the microscope, that is, the full coverage state when the 100% proportion will not appear between each black pigment dot. And the 40% of black pigment points of all black information in the color user identity information printed by the ink layer 5 are subjected to scattered orderly coverage and overlapping on 70% of black pigment points etched by laser, so that full user identity information under normal vision is formed. This forms an orderly overlap of black pigment spots under the microscope to check for artifacts.
The anti-counterfeiting card manufactured under the condition of taking the area as a variable is taken as an example according to the method of the invention:
as a variable printing anti-fake card manufactured by the method, black and white user identity information is etched on a laser etching layer 2 according to a first area variable, namely, etching of the user identity information is performed by using a first area (a certain area or a certain area of the user identity information, such as a certain stroke area in a user name or a certain digital area of a certificate number) set by the area variable; the ink layer 5 prints black information in the user color identity information according to the second area variable, i.e., the black ink is used to print through the second area (complementary to the area in the first ratio) set by the area variable, while the color information in the other color identity information is printed normally. Specifically, for example, the first ratio is set as the first horizontal of the "king" character in the name "Wang Gang" is laser etching, the lower "earth" character is black ink spraying of color ink, so as to form normal user identity information which is indiscriminate under vision, and when under a microscope, the difference between the etched pigment points and the ink pigment points can be obviously seen so as to check the falsification.

The ink is printed firstly, then the laser is used for printing, the place where the laser needs to be printed is left empty, and the laser passes through the second transparent protective layer, the transparent coating and the first transparent protective layer to form an image on the etching layer. And the pattern color of the first variable laser etching layer and the pattern color printed by the second variable layer ink are overlapped to realize the pattern color reduction.
Three kinds of information can be stored on the cloud server, namely, the real original card image-text information of the user, the real information of the image-text printing variable and the outline anti-counterfeiting mark information of the user, and the three kinds of information can be stored in different positions of the cloud server so as to prevent falsification of the cloud information by a counterfeiter. The verification module can respectively call the three kinds of information to verify authenticity.
According to the invention, through setting the variable of the proportion and/or the area of the laser etching quantity and the ink spraying quantity, the black and white user identity information etched on the laser etching layer according to the first proportion and/or the area and all black information in the user color identity information printed on the ink layer according to the second proportion and/or the area are orderly overlapped and/or partially complementary under a microscope, so that identification of a fake card is facilitated, the variable can be set in a first card, and the identification and authentication of a cloud server are matched, so that the performance of the fake card is improved; and the image-text reserved file with the original setting state and the authenticity verification module are stored on the cloud server and used for verifying the melanin proportion of the black part and/or the correctness of the region, and the card to be verified is effectively identified and the authenticity is distinguished, so that the safety and the reliability of the anti-fake card are improved; in addition, the outline-shaped anti-counterfeiting mark printed by optically variable ink, which is consistent with the outline of the image information of the user, is arranged in the second transparent protective layer and is framed on the periphery of the image information of the user formed by overlapping laser etching and ink printing, and because the outline-shaped anti-counterfeiting mark is consistent with the image outlines of the black-and-white image and the color image, when the color image is tampered maliciously, the outline of the anti-counterfeiting mark is not matched with the outline of the black-and-white image and the tampered color image, so that the identification and the identification of whether the card is tampered or not are facilitated for people.
