[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the following is a Figure 1-4 The invention is further described with examples.

[0026] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0027] As attached Figure 1 As shown, the utility model provides a variable printing anti-counterfeiting card, which includes a substrate layer 1, a laser etching layer 2, a first transparent protective layer 3, an ink layer 4 and a second transparent protective layer 5 which are stacked in sequence.

[0028] Substrate layer 1: generally polyvinyl chloride, polycarbonate. For single-sided anti-counterfeiting cards (such as some entry cards, etc.), substrate layer 1 is at the bottom of the card, and laser etching layer 2, first transparent protective layer 3, ink layer 4 and second transparent protective layer 5 can be arranged from bottom to top; for double-sided anti-counterfeiting cards (such as the front and back of identity cards, etc.), substrate layer 1 is in the middle layer of the card, and laser etching layer 2, first transparent protective layer 3, ink layer 4 and second transparent protective layer 5 can be arranged from the middle layer to the top or bottom.

[0029] Laser etching layer 2: Laser etching is a technology that uses a laser beam to directly evaporate or ablate the surface material of an object. Etching of materials can be achieved by controlling the laser. Laser etching layer 2 can generally be to add carbon and other materials to the PC material, which will partially pyrolyze when subjected to a high-intensity laser beam to form carbides that are deposited in the etching area, thereby forming a black pattern. These are already existing technologies and will not be repeated here. Due to the high energy of laser etching, the user identity information is etched in a destructive manner, so the user identity information obtained by laser etching has the effect of being difficult to tamper with. At the same time, when laser etching these etching materials, a black effect can be perfectly etched. The laser etching layer 2 of the utility model is used to etch the user identity information by laser etching. After laser etching, the black-and-white identity information of the user is generated in the laser etching layer 2 of the card, and the user identity information includes image information and text information; wherein, the black-and-white image information includes the user's portrait, and the text information includes the user's name, ID number and other text information related to the user's identity; wherein, the user identity information is etched on the laser etching layer 2 of the utility model according to the first variable, and the user identity information may include all or part of the black-and-white image and text information; the variable here can be a ratio, an area, or a superposition of a ratio and an area.

[0030] When the variable is a ratio, at this time, the first variable is the first ratio, which is the set etching ratio when laser etching the user identity information; the second variable is the second ratio, which is the set melanin printing ratio when ink prints the black part of the user identity information and the 100% normal printing ratio when the color part is printed. At this time, there are several settings:

[0031] The first type: the first ratio is 100%, that is, the set etching ratio when laser etching the user identity information is 100%; the second ratio is 0, that is, the set melanin printing ratio when the ink prints the black part of the user identity information is 0 and the normal printing ratio when the color part is 100%. At this time, it is equivalent to that the black part of the user identity information is all laser etched, and the ink is not printed. During verification, see whether the black part of the information only presents the laser etched pigment points under the microscope, which is convenient for the identification of false evidence.

[0032] The second type: the first ratio is <100%, that is, the set etching ratio when laser etching the user identity information is <100%; the second ratio is >0, that is, the set melanin printing ratio when the ink prints the black part of the user identity information is >0 and the normal printing ratio of 100% when the color part is printed. For example: the first ratio is 70% and the second ratio is 40%. At this time, if the laser etching is originally to print 100 pigment dots (100% ratio), after choosing to reduce its ratio to 70% for printing, it means that the printed result will only contain 70% of the original number of pigment dots, so in fact only 70 laser-etched pigment dots will be printed, as shown in the attached figure 6. Figure 2 If the inkjet printer is supposed to print 100 pigment dots (100% ratio), and it is chosen to reduce the ratio to 40% for printing, then only 40 ink-printed pigment dots will actually be printed 7. After the two print results are aligned and overlapped, the black part information and the color part information of the complete user identity information are presented. However, as shown in the attached figure, Figure 3 As shown in FIG. 1 , the black part information will appear in an orderly overlapping state under a microscope. In actual operation, the sum of the set etching ratio and the set melanin printing ratio can be set to about 100% (as shown in FIG. 1 ). Figure 4 As shown) or greater than 100% to ensure the fullness of the graphic information. Moreover, the overlapping and interlacing of the pigment dots is not perfectly complementary even under a microscope at the microscopic level, but there are some uneven overlaps, interlacing, and blank areas. However, because the human eye's perception of color is relative, it will perceive color according to the surrounding color and light brightness, so it does not affect the visual effect of image printing under human vision. During verification, see whether the black part of the information presents orderly overlapping and interlacing of the pigment dots under a microscope, which is convenient for the identification of false evidence. In addition, this variable can be set for each certificate, and can be used with the comparison files pre-stored in the cloud server for identification and appraisal, thereby improving the performance of anti-counterfeiting cards.

[0033] When the variable is an area, the first variable is the first area, which is the set etching area when the user identity information is laser-etched; the second variable is the second area, which is the set melanin printing area when the black part of the user identity information is printed with ink and the 100% normal printing area when the color part is printed. The set etching area overlaps with the set melanin printing area to form the black part of the complete user identity information. At this time, the complementary state of each part of the black part area is presented under a microscope, and this variable can also be set for each certificate, which can be used with the recognition and identification of the cloud server to improve the performance of the anti-counterfeiting card.

[0034] First transparent protective layer 3: generally made of PC material; setting the first transparent protective layer 3 on the laser etching layer 2 of the anti-counterfeiting card has the following advantages: Improve durability: The first transparent protective layer 3 can effectively protect the laser etching layer 2 from damage by the external environment, such as scratching, friction and chemical erosion. This can extend the service life of the anti-counterfeiting card and make it more durable. Prevent the etching layer from being damaged by human beings: The first transparent protective layer 3 can effectively prevent the laser etching layer 2 from being scratched or scraped off by human beings. Without the transparent protective layer, the laser etching layer 2 may be easily damaged, resulting in the exposure or tampering of the anti-counterfeiting features. Increase optical effect: The transparent protective layer can increase the optical effect of the anti-counterfeiting card, such as improving the clarity of the laser etching pattern, increasing the reflective effect, etc. This can make the anti-counterfeiting card more eye-catching, improve its recognition and anti-counterfeiting effect. Difficult to imitate: The setting of the transparent protective layer can increase the complexity of the anti-counterfeiting card, making it more difficult for counterfeiters to replicate the exact same appearance. By using special materials or processes to make a transparent protective layer, the difficulty of imitation of anti-counterfeiting cards can be further increased, and the anti-counterfeiting performance can be improved. Especially when the substrate is a metal material, a relatively smooth surface is often formed after laser etching, which is not conducive to the adhesion of the subsequent ink, thus affecting the printing effect.

[0035] Ink layer 4: The YMCK color printing mode is commonly used, which represents four color channels: Yellow, Magenta, Cyan and Key. The YMCK printing mode is based on the principle of color superposition. By superimposing the ink cartridges of these four color channels in sequence during the printing process, rich color effects can be produced. Through this color superposition method, the YMCK printing mode can achieve more accurate and rich color printing effects. It is often used in printing color photos, images, business cards, certificates and other occasions that require high-quality color output. During the spraying process, the printer will spray four colors of ink according to certain rules and methods according to the required pattern or text. Since each spray is in the same position, the ink dots will gradually overlap to form larger and denser pigment dots, and finally present the required color effect.

[0036] Before printing the ink layer 4, the printer performance is set first. When making the card of the utility model, the color picking mode of the printer needs to be set to three-color black. The color picking mode of three-color black refers to the black color printed by M0 Y0 C0 K100. The color image is printed on the black and white image etched by the laser in an overlapping manner, so that the color image and the black and white image are aligned and overlapped with each other to obtain a personalized information surface; that is, the black and white image is covered with a color image layer, and the color image layer and the black and white image are aligned with each other; the ink layer 4 prints all or part of the color user identity information including the black partial image and text information according to the second variable, and the color partial image and text information are printed normally. The second variable can include a second ratio and a second area.

[0037] Second transparent protective layer 5: In order to increase the durability and protective effect of the printed product, a transparent protective coating is added to the top layer of the print. On the second transparent protective layer 5, a contour anti-counterfeiting mark is provided which is printed with optically variable ink and is consistent with the contour of the user's image information.

[0038] The printed contour-shaped anti-counterfeiting mark frame is set on the periphery of the user image information formed by the overlapping of laser etching and ink printing. Since the contour-shaped anti-counterfeiting mark is consistent with the image contours of the black-and-white image and the color image, and the image contours of users vary greatly due to gender, hairstyle, clothing, etc., when the color image is maliciously tampered with, the anti-counterfeiting mark and the black-and-white image and the contours of the tampered color image will not match, making it easier for people to identify whether the card has been tampered with.

[0039] Embodiment 1:

[0040] Take the anti-counterfeiting card as an example when the variable is a proportion:

[0041] As a variable printing anti-counterfeiting card provided by the present utility model, black and white user identity information is etched on the laser etching layer 2 according to a first proportional variable, that is, the user identity information is etched using black with a first ratio (100% or other ratios greater than 0 and less than 100%) set by the proportional variable (generally speaking, in order to ensure the anti-counterfeiting effect of laser etching, the etching ratio will not be set too low); the ink layer 4 prints all the black information in the user's color identity information according to a second proportional variable, that is, it is printed using black ink with a second ratio (0 when the first ratio is 100% or other ratios less than 100%) set by the proportional variable, while the color information in other color identity information is printed normally. It should be noted that to ensure a more saturated display effect, the sum of the first ratio and the second ratio needs to be around 100% or greater than 100%. For example, the first ratio is set to 70% and the second ratio is set to 40%. At this time, there will be some blank areas between the 70% black pigment dots etched by laser under the microscope, that is, the full coverage state when the proportion is 100% will not be shown between the black pigment dots. 40% of the black pigment dots of all the black information in the color user identity information printed by the ink layer 4 cover and overlap the 70% black pigment dots etched by laser in a dispersed and orderly manner, forming a saturated user identity information under normal vision, so that an orderly overlap of black pigment dots is formed under the microscope for anti-counterfeiting inspection.

[0042] Example Two:

[0043] Taking the anti-counterfeiting card with variables as regions as an example:

[0044] As a variable printing anti-counterfeiting card provided by the present utility model, black and white user identity information is etched on the laser etching layer 2 according to a first regional variable, that is, the user identity information is etched using a first region (a certain or some regions of the user identity information, such as some stroke regions in the user's name or some digit regions in the ID number) set by the regional variable; the ink layer 4 prints the black information in the user's color identity information according to a second regional variable, that is, it is printed using black ink with a second region (complementary to the region in the first ratio) set by the regional variable, while the color information in other color identity information is printed normally, and the pattern color is restored after superposition. Specifically, for example, the first ratio is set such that the first horizontal stroke of the character "Wang" in the name "Wang Gang" is laser-etched, and the following "Tu" character is sprayed with black ink of color ink, forming a normal user identity information with no difference in vision. Under the microscope, the difference between the etched pigment dots and the ink pigment dots can be clearly seen for anti-counterfeiting inspection.

[0045] Example Three:

[0046] As another embodiment of the present invention, the anti-counterfeiting card can be produced by mixing proportional variables and regional variables.

[0047] Applied to the above-mentioned embodiment, the process of making a variable printing anti-counterfeiting card includes the following steps:

[0048] S1. Pre-made blank card materials;

[0049] The prefabricated blank material is formed by pressing the substrate layer 1, the laser etching layer 2, and the first transparent protective layer 3 together to form a PC material.

[0050] S2, on a blank card material, using a laser to etch the user identity information on the laser etching layer 2 according to the first variable;

[0051] When making a personalized card, laser etching is first performed, and the laser can pass through the first transparent protective layer 3 to form user identity information including patterns and texts on the laser etching layer 2. The user identity information is a black and white image and text information.

[0052] The laser etching layer 2 of the utility model is etched with user identity information according to the first variable, and the user identity information includes a black and white image and text information; the first variable may include a first ratio and / or a first area, wherein the ratio and the area can be set for one card (can also be set by date or time period), which is equivalent to one card and one password, and a graphic and text backup file of the original setting state is stored in the cloud server for reference. The cloud server is equipped with a verification module for verifying the correctness of the melanin ratio and / or area of ​​the black part, which can effectively identify the pigment ratio and / or area of ​​the card to be verified and distinguish the authenticity.

[0053] S3, printing process of the etched card, specifically including:

[0054] S31, printing user identity information of the ink layer 4 on the first transparent protective layer 3 according to the second variable;

[0055] Before printing, set the printer performance and set the printer's color picking mode to three-color black. The color picking mode of three-color black is different from that of ordinary four-color black. The commonly used YMCK color printing mode represents four color channels: yellow (Yellow), red (Magenta), cyan (Cyan) and black (Key). The color picking mode of three-color black refers to the black printed by M0 Y0 C0 K100. The color picking mode of four-color black is C75 M68 Y67 K90, which is the black printed by superimposing four colors. When the color picking mode is three-color black, the printed black and white image will only have melanin after being magnified by a microscope, and no other pigment dots will be mixed. The color information in the color image and text information is a mixed display of normal pigments.

[0056] After the setting is completed, the color image and text information of the user identity information are printed on the first transparent protective layer 3 above the etched black and white image and text information according to the second variable using color ink, so that the color image and text information are aligned and overlapped with the etched black and white image and text information to obtain a personalized information surface. When the first variable is the first ratio, the first ratio is 100%, that is, the set etching ratio when the laser is etching the user identity information is 100%; the second ratio is 0, that is, the set melanin printing ratio when the ink is printing the black part of the user identity information is 0 and the normal printing ratio of 100% when the color part is printed, the melanin of the color ink is not sprayed at this time. In other cases, spray according to the setting.

[0057] When checking for falsehood, if there are other pigments of ink in the black part of the user identity information, it is false (no three-color black printing), only ink black pigment is false (no laser etching), no overlapping nesting or incorrect overlapping nesting mode (not printing according to the set variables) is also false. Among them, the first proportion of the special setting variable printing situation is 100%, and the second proportion is 0, then only the etched black pigment is true.

[0058] The specific data of the proportion and area in the variable printing can be set one by one, or by date or time period for inspection.

[0059] In addition, these can also be verified through the verification module available on the cloud server. The verification module can combine the recognition of proportions or areas to verify the difference between the original correct setting mode and the card to be verified to identify the authenticity of the card.

[0060] S32, printing a second transparent protective layer 5 on the ink layer 4, wherein the transparent protective layer can achieve high-quality color printing effect;

[0061] S33, on the second transparent protective layer 5, use optically variable ink to print an outline anti-counterfeiting mark that is consistent with the outline of the user image information.

[0062] The printed contour-shaped anti-counterfeiting mark frame is set on the periphery of the user image information formed by the overlapping of laser etching and ink printing. Since the contour-shaped anti-counterfeiting mark is consistent with the image contours of the black-and-white image and the color image, when the color image is maliciously tampered with, the anti-counterfeiting mark and the black-and-white image and the contours of the tampered color image will not match, making it easier for people to identify whether the card has been tampered with.

[0063] Furthermore, the process of making a variable printing anti-counterfeiting card of the utility model can also be:

[0064] P1, pre-made blank card materials;

[0065] P2. Print the user identity information of the ink layer on the first transparent protective layer according to the second variable. When printing, leave a blank where the laser needs to be etched, and then print the ink part to form an ink layer;

[0066] P3, printing a second transparent protective layer on the ink layer;

[0067] P4. On the card material, laser is used to penetrate the second transparent protective layer and the first transparent protective layer, and the user identity information is etched on the laser etching layer according to the first variable. The user identity information of the black water layer is aligned and overlapped with the user identity information of the laser etching layer as a whole, and the color restoration of the pattern is achieved after superposition.

[0068] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0069] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
