Description

Technical Field

[0001] The present invention relates to the field of anti-counterfeiting technology, and particularly to an anti-counterfeiting and traceability method for the production information of intaglio water-based ink printing. Background Art

[0002] The anti-counterfeiting and traceability technology of intaglio water-based ink printing ensures the accurate positioning and traceability of each product throughout its life cycle by recording and tracking all links in the production process, involving information such as production data, production batches, equipment usage, and raw material sources, which helps manufacturers and consumers understand the origin, quality, and circulation process of products.

[0003] Existing methods usually generate traceability codes based on the production information of key production links in the product production process, and randomly select the information of the remaining production links to produce anti-counterfeiting codes, and combine them to obtain product traceability codes; however, due to the poor correlation between the production links of the randomly selected anti-counterfeiting codes and the key production links, the anti-counterfeiting codes miss key data in the production process and the traceability chain may be incomplete, thus reducing the accuracy and security of the traceability codes. Summary of the Invention

[0004] In order to solve the technical problem that the correlation between the production links randomly selected in the product production process and the key production links is poor, reducing the accuracy and security of the traceability code, the purpose of the present invention is to provide an anti-counterfeiting and traceability method for the production information of intaglio water-based ink printing, and the specific technical solution adopted is as follows:

[0005] The present invention provides an anti-counterfeiting and traceability method for the production information of intaglio water-based ink printing, and the method includes:

[0006] Obtain the final quality score sequence of intaglio water-based ink printing products in the same batch and the link quality score sequence in the same production link;

[0007] According to the correlation degree and difference between the link quality score sequence of the intaglio water-based ink printing product in each production link and the link quality score sequences of the remaining production links, screen out the strongly correlated links of each production link;

[0008] According to the correlation degree between the link quality score sequence of each production link and the final quality score sequence, and the dispersion degree of the elements in the link quality score sequence, obtain the final quality contribution degree of each production link;

[0009] According to the correlation degree between the link quality score sequence of the production link between each production link and its strongly correlated links and the final quality score sequence, and the final quality contribution degree, adjust the correlation degree between each production link and its strongly correlated links, and screen out the strongly correlated links in the same direction of each production link;

[0010] Based on the final quality contribution degree of the strongly associated links in the same direction of the production links, determine the display link and the anti-counterfeiting link, and generate a product traceability code based on the production data of the display link and the anti-counterfeiting link of each gravure water-based ink printed product.

[0011] Further, the screening of the strongly associated links of each production link includes:

[0012] Determine the quality analysis elements of each element in the link quality score sequence of each production link; based on the differences between all elements in the link quality score sequence of each production link and their quality analysis elements, obtain the overall quality deterioration index of each production link.

[0013] Obtain the correlation coefficients between the link quality score sequences of each production link and the other production links respectively; based on the differences between the overall quality deterioration indexes of each production link and the other production links respectively and the correlation coefficients, obtain the link association degrees between each production link and the other production links respectively.

[0014] Based on the link association degrees, select the strongly associated links of each production link.

[0015] Further, the screening of the strongly associated links in the same direction of each production link includes:

[0016] Based on the correlation degree between the link quality score sequence of all production links between each production link and its each strongly associated link and the final quality score sequence and the final quality contribution degree, obtain the interference coefficient between each production link and its each strongly associated link.

[0017] Use the interference coefficient to adjust the link association degree between each production link and its each strongly associated link, obtain the corrected link association degree between each production link and its each strongly associated link; based on the corrected link association degree, select the strongly associated links in the same direction from the strongly associated links of each production link.

[0018] Further, the determination of the display link and the anti-counterfeiting link includes:

[0019] Calculate the mean value of the final quality contribution degrees of all the strongly associated links in the same direction of each production link as the association contribution degree of each production link; select the production link corresponding to the maximum value among the association contribution degrees of all production links of the gravure water-based ink printed product as the traceability link.

[0020] For the traceability link and all its strongly associated links in the same direction, respectively take the link corresponding to the maximum final quality contribution degree as the display link, and the remaining links as the anti-counterfeiting links.

[0021] Further, the obtaining of the final quality contribution degree of each production link includes:

[0022] Obtain the correlation coefficient between the quality score sequence of each production link and the final quality score sequence;

[0023] Perform a negative correlation mapping on the variance of the elements in the quality score sequence of each production link, and take the product of the mapping result and the correlation coefficient between the quality score sequence of each production link and the final quality score sequence as the final quality contribution degree of each production link.

[0024] Furthermore, the obtaining of the overall quality deterioration index of each production link includes:

[0028] Furthermore, the obtaining of the corrected association degree between each production link and each of its strongly associated links includes:

[0029] Perform negative correlation and normalization processing on the interference coefficient, and perform weighted processing on the link association degree between each production link and each of its strongly associated links based on the processing result to obtain the corrected association degree between each production link and each of its strongly associated links.

[0030] Furthermore, each element in the quality score sequence of the production link is not equal to the corresponding element in the final quality score sequence of its quality analysis element.

[0031] Furthermore, the correlation coefficient is the Pearson correlation coefficient.

[0032] The present invention has the following beneficial effects:

[0033] In the embodiments of the present invention, to avoid excessive leakage of key production data in product traceability codes, the production mode in the production process is extracted to generate a unique production logic for ink-printed products, specifically as follows: the degree of correlation and differences between the quality score sequences of each production link and the rest of the production links are analyzed in turn from the aspects of quality correlation and chain reaction to analyze the degree of association of different production links, and strongly associated links are selected; based on the degree of correlation between different production links, key information in the production process is determined to obtain the final quality contribution degree of production quality; since the quality fluctuations of the production links between each production link and its strongly associated links may interfere with or change the degree of association between the corresponding two production links, it is necessary to use the quality changes in the intermediate production links to adjust the degree of association between each production link and each of its strongly associated links, so as to better cope with the possible changes in the production process and improve the accuracy of the strongly associated links in the same direction; the key display links and the anti-counterfeiting links with a relatively strong degree of association in the product production process are determined, so that the anti-counterfeiting links can directly reflect the core production process of the product, thereby providing more accurate product traceability information, strengthening the anti-counterfeiting effect and enhancing the traceability security.

[0040] In order to further elaborate on the technical means and effects adopted by the present invention to achieve the intended invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details a method for anti-counterfeiting and traceability of intaglio water-based ink printing production information proposed according to the present invention, including its specific implementation manner, structure, features, and effects. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs.

[0042] The following specifically describes the specific solution of a method for anti-counterfeiting and traceability of intaglio water-based ink printing production information provided by the present invention in conjunction with the accompanying drawings.

[0043] Example 1:

[0044] The present invention proposes a method for anti-counterfeiting and traceability of intaglio water-based ink printing production information. Please refer to Figure 1 , which shows the step flowchart of a method for anti-counterfeiting and traceability of intaglio water-based ink printing production information provided by an embodiment of the present invention. The method includes:

[0045] Step S1: Obtain the final quality score sequence of intaglio water-based ink printing products in the same batch and the in-process quality score sequence in the same production process.

[0046] The production processes of intaglio water-based ink printing products are, in sequence, the raw material preparation process, the ink formulation process, the intaglio printing process, the drying and curing process, and the packaging and shipping process. Combining integrated sensors and manual data recording, collect the production data of intaglio water-based ink printing products in the same batch during the ink printing process in each production process, specifically as follows:

[0047] The production data of the raw material preparation process includes: the batch number of raw materials, supplier information, and production date; the production data of the ink formulation process includes: the ratio of pigments and solvents, the temperature and humidity during the formulation process; the production data of the intaglio printing process includes: the temperature, pressure, and humidity of the production equipment during the printing process, the usage amount, quality, and viscosity of the ink; the production data of the drying and curing process includes: the drying temperature and wind speed; the production data of the packaging and shipping process includes: the production batch number, packaging information, and logistics tracking information.

[0048] Use blockchain technology to store the production data of each production process of intaglio water-based ink printing products to ensure the persistence, immutability, and high availability of the data.

[0049] Input all production data of each production link of each gravure water-based ink printing product into the trained neural network. The neural network outputs a score between 0 and 1, which is recorded as the link quality score of the corresponding production link. Use a color difference meter and a densitometer to collect the total color difference of each gravure water-based ink printing product in turn and ink concentration. The smaller the total color difference and the larger the ink concentration, the clearer the printed product and the better the quality. Normalize the total color difference and ink concentration of each gravure water-based ink printing product respectively, and use the difference between the constant 1 and the normalized total color difference and the mean value of the normalized ink concentration as the final quality score of each gravure water-based ink printing product.

[0050] Arrange the link quality scores of the same production link of all gravure water-based ink printing products in the same batch in order to form a link quality score sequence for each production link; arrange the final quality scores of all gravure water-based ink printing products in the same batch in order to form a final quality score sequence.

[0051] It should be noted that the elements with the same subscript in all link quality score sequences and the final quality score sequence represent the relevant quality scores of the same gravure water-based ink printing product; there are differences in the quality of gravure water-based ink printing products in the same batch.

[0052] Step S2: According to the correlation degree and difference between the link quality score sequences of the gravure water-based ink printing products in each production link and the other production links, screen the strongly correlated links in each production link.

[0053] There is a strong correlation between different production links in the production process of gravure water-based ink printing products. Production links with a strong correlation degree will cause a chain reaction. For example, the ratio of pigments and solvents in the ink preparation link affects the rheological properties and uniformity of the ink, which in turn affects the drying effect in the subsequent drying and curing link. Therefore, the correlation degree between the ink preparation link and the drying and curing link is relatively strong.

[0054] The correlation degree between each production link and the link quality score sequences of the other production links directly presents the correlation degree between different production links; the link quality score sequence represents the quality situation of each production link, and the difference between the link quality score sequences of each production link and the other production links presents the possibility that the quality changes between each production link and the other production links are caused by chain reactions; by comprehensively analyzing the two factors, the accuracy of the correlation degree between each production link and the other production links is effectively improved, so as to select the strongly correlated links with a relatively strong correlation degree with each production link.

[0055] Please refer to Figure 2 , which shows the step flowchart of a method for obtaining strongly correlated links provided by an embodiment of the present invention. The method includes:

[0056] Step S210: Determine the quality analysis elements of each element in the link quality score sequence of each production link; obtain the overall quality deterioration index of each production link according to the differences between all elements in the link quality score sequence of each production link and their quality analysis elements.

[0057] If the final quality scores of multiple gravure water-based ink printing products are equal, the link quality scores of these ink printing products in the same production link should be relatively close, and it is impossible to accurately evaluate the true impact of each production link on other links. Therefore, when analyzing the impact of a single production link on the quality of printing products, screen the link quality scores of ink printing products with different final quality scores in the same production link for analysis to obtain the quality analysis elements of each element. In an implementation manner of the embodiment of the present invention, each element in the link quality score sequence is not equal to the corresponding element in the final quality score sequence for its quality analysis element. It should be noted that the subscripts of each element in the link quality score sequence and the corresponding elements in the final quality score sequence are equal.

[0058] In a specific implementation manner of the embodiment of the present invention, the specific method for obtaining the overall quality deterioration index is as follows: calculate the absolute value of the difference between each element in the link quality score sequence of each production link and the mean value of all its quality analysis elements as the local quality deterioration index of each element; take the mean value of the local quality deterioration indexes of all elements in the link quality score sequence of each production link as the overall quality deterioration index of each production link. The overall quality deterioration index E of each production link is expressed by the formula:

[0059]

[0060] In the formula, N is the total number of elements in the link quality score sequence of each production link, that is, the total number of gravure water-based ink printing products in the same batch; is the nth element in the link quality score sequence of each production link; is the mean value of all quality analysis elements of the nth element in the link quality score sequence of each production link; is the local quality deterioration index of the nth element in the link quality score sequence of each production link; is the absolute value function. It should be noted that represents the standard production level of each production link. If is larger, it means that the ink printing product corresponding to the nth element in the link quality score sequence of each production link has a more significant production precision error in this production link, the impact of this production link on the subsequent production links is greater, the production quality deterioration of this production link is more serious, and the overall quality deterioration index E is larger.

[0061] Step S220: Obtain the correlation coefficients of the quality score sequences of each production link with the other production links respectively; based on the differences and correlation coefficients between the overall quality deterioration indexes of each production link and the other production links respectively, obtain the link correlation degrees of each production link with the other production links respectively.

[0062] In a specific implementation manner of the embodiment of the present invention, the link correlation degree is expressed by the formula:

[0063]

[0064] In the formula, is the link correlation degree of the u-th production link with the v-th other production link; is the quality score sequence of the u-th production link; is the quality score sequence of the v-th other production link except the u-th production link; is the correlation coefficient of the u-th production link with the v-th other production link; is the overall quality deterioration index of the u-th production link; is the overall quality deterioration index of the v-th other production link except the u-th production link; is the absolute value function; Norm is the normalization function. It should be noted that if is larger, the correlation degree between the u-th production link and the v-th other production link is stronger; because the quality of the production links with a strong correlation degree will produce a chain reaction, that is, if there is a quality problem in a certain production link, the production links with a strong correlation degree with it will also have quality problems. Therefore, if is smaller, the greater the possibility that the production quality change between the u-th production link and the v-th other production link is caused by a chain reaction, and the stronger the correlation degree between the two production links, is larger.

[0065] In an implementation manner of the embodiment of the present invention, the correlation coefficient is the Pearson correlation coefficient; in other embodiments of the present invention, the correlation coefficient can also be the Spearman correlation coefficient, the Kendall rank correlation coefficient, the canonical correlation coefficient, etc. The correlation coefficients in other positions in the specification are selected in the same way as the correlation coefficient here.

[0066] Step S230: Based on the link correlation degrees, select the strongly correlated links of each production link.

[0067] The greater the degree of association between each production link and the remaining production links respectively, the greater the degree of association between each production link and the remaining production links. In one implementation of the embodiment of the present invention, for the degree of association between each production link and the remaining production links respectively, the production link corresponding to the degree of association greater than the preset association threshold is used as the strong association link of each production link.

[0068] In one implementation of the embodiment of the present invention, the preset association threshold is set to 0.7, and the implementer can set it according to specific circumstances.

[0069] Step S3: Obtain the final quality contribution degree of each production link according to the correlation degree between the link quality score sequence of each production link and the final quality score sequence, and the dispersion degree of the elements in the link quality score sequence.

[0070] Due to the differences in the gravure water-based ink printing process and product requirements, the influence degrees of the quality of different production links of gravure water-based ink printing products on the final quality score are different. The dispersion degree of the elements in the link quality score sequence reflects the required precision of each production link for production data, which in turn affects the product quality. Combining the correlation degree between the link quality score sequence of each production link and the final quality score sequence, analyze the importance degree of each production link to the product quality, and obtain the final quality contribution degree.

[0071] In one implementation of the embodiment of the present invention, the method for obtaining the final quality contribution degree is: obtain the correlation coefficient between the link quality score sequence of each production link and the final quality score sequence; perform a negative correlation mapping on the variance of the elements in the link quality score sequence of each production link, and take the product of the mapping result and the correlation coefficient between the link quality score sequence of each production link and the final quality score sequence as the final quality contribution degree of each production link. The final quality contribution degree is expressed by the formula:

[0072]

[0073] In the formula, is the final quality contribution degree of the u-th production link; is the link quality score sequence of the u-th production link; ZX is the final quality score sequence; is the correlation coefficient between the link quality score sequence of the u-th production link and the final quality score sequence; is the variance of the elements in the link quality score sequence of the u-th production link. The function in the formula is used to perform a negative correlation mapping on . It should be noted that if The smaller it is, the more stable the production data of the u-th production link during the printing process. The higher the precision requirement of the production link for the production data, it indicates that the contribution degree of the u-th production link to the quality of the gravure water-based ink printing product is greater. Then the larger; if is larger, the greater the impact of the u-th production link on the product quality, then the greater the contribution of the u-th production link to the product quality. the larger.

[0074] Step S4: According to the correlation degree and the final quality contribution degree between the link quality score sequence and the final quality score sequence of the production links between each production link and each of its strongly associated links, adjust the association degree between each production link and each of its strongly associated links, and screen out the same-direction strongly associated links of each production link.

[0075] There may be multiple production links between each production link and each of its strongly associated links. If the intermediate production link can significantly affect the quality of the ink printing product, the quality fluctuation of the intermediate production link may interfere with or change the association degree between each production link and each of its strongly associated links. The correlation degree and the final quality contribution degree between the link quality score sequence and the final quality score sequence of the production link can both reflect the influence degree of the production link on the product quality. By using these two factors to adjust the association degree between each production link and each of its strongly associated links, the same-direction strongly associated links are determined.

[0076] Please refer to Figure 3 , which shows the step flow chart of a method for obtaining the same-direction strongly associated links provided by an embodiment of the present invention. The method includes:

[0077] Step S410: According to the correlation degree and the final quality contribution degree between the link quality score sequence and the final quality score sequence of all the production links between each production link and each of its strongly associated links, obtain the interference coefficient between each production link and each of its strongly associated links.

[0078] In an implementation manner of the embodiment of the present invention, the method for obtaining the interference coefficient is: taking the sum of the products of the correlation coefficient between the link quality score sequence and the final quality score sequence of all the production links between each production link and each of its strongly associated links and the final quality contribution degree as the interference coefficient obtained between each production link and each of its strongly associated links. The interference coefficient is expressed by the formula:

[0079]

[0080] In the formula, is the interference coefficient between the u-th production link and its c-th strongly associated link; is the total number of production links between the $u$-th production link and its $c$-th strongly associated link; is the final quality contribution degree of the $m$-th production link between the $u$-th production link and its $c$-th strongly associated link; is the sequence of link quality scores of the $m$-th production link between the $u$-th production link and its $c$-th strongly associated link; ZX is the sequence of final quality scores; is the correlation coefficient between the sequence of link quality scores of the $m$-th production link between the $u$-th production link and its $c$-th strongly associated link and the sequence of final quality scores. It should be noted that if and the larger, the greater the impact of the $m$-th production link on the product quality, then the greater the degree of interference of the $m$-th production link on the association degree between the $u$-th production link and its $c$-th strongly associated link, and the interference coefficient is larger.

[0081] Step S420: Adjust the link association degree between each production link and each of its strongly associated links using the interference coefficient to obtain the corrected association degree between each production link and each of its strongly associated links; based on the corrected association degree, select the co-directional strongly associated links from the strongly associated links of each production link.

[0082] The link association degree between each production link and each of its strongly associated links presents the association degree between the corresponding two production links. If the degree of interference generated by the production links between two production links is greater, it will weaken the association degree between each production link and each of its strongly associated links, and then the corrected association degree is smaller.

[0083] In an implementation manner of the embodiment of the present invention, the method for obtaining the corrected association degree is: perform negative correlation and normalization processing on the interference coefficient, and perform weighted processing on the link association degree between each production link and each of its strongly associated links based on the processing result to obtain the corrected association degree between each production link and each of its strongly associated links. The corrected association degree is expressed by the formula:

[0084]

[0085] In the formula, is the corrected association degree between the $u$-th production link and its $c$-th strongly associated link; is the link association degree between the $u$-th production link and its $c$-th strongly associated link; is the interference coefficient between the $u$-th production link and its $c$-th strongly associated link; Norm is the normalization function.

[0086] If the correction correlation degree between each production link and each of its strongly associated links is greater, then the degree of association between the corresponding two production links is greater. In one implementation of the embodiment of the present invention, for the correction correlation degree between each production link and all its strongly associated links, the strongly associated links corresponding to the correction correlation degree greater than the preset same-direction association threshold are used as the same-direction strongly associated links of each production link.

[0087] In one implementation of the embodiment of the present invention, the preset same-direction association threshold is set to 0.6, and the implementer can set it according to specific circumstances.

[0088] Step S5: Determine the display link and the anti-counterfeiting link according to the final quality contribution degree of the same-direction strongly associated links of the production link, and generate a product traceability code based on the production data of the display link and the anti-counterfeiting link of each gravure water-based ink printed product.

[0089] To avoid excessive leakage of key production data in the product traceability code, it is necessary to extract the production information with anti-counterfeiting significance during the production process of the gravure water-based ink printed product, extract the specific production mode in the production link, generate the unique production logic of the ink printed product, determine the display link and the anti-counterfeiting link, strengthen the anti-counterfeiting effect and improve the traceability security.

[0090] Preferably, in some possible implementation manners of the embodiment of the present invention, the method for obtaining the display link and the anti-counterfeiting link is as follows: calculate the mean value of the final quality contribution degrees of all the same-direction strongly associated links of each production link as the association contribution degree of each production link; select the production link corresponding to the maximum value among the association contribution degrees of all the production links of the gravure water-based ink printed product, and denote it as the traceability link; for the traceability link and all its same-direction strongly associated links, respectively take the link corresponding to the maximum final quality contribution degree as the display link, and the remaining links as the anti-counterfeiting links. The production link with the maximum association contribution degree is the most important for the gravure water-based ink printed product. Take this production link as the protection object and display object of the product, and incorporate the production data of the same-direction strongly associated links of this production link into the anti-counterfeiting information, thereby strengthening the anti-counterfeiting effect and improving the traceability security.

[0091] The specific process of generating the product traceability code based on the production data of the display link and the anti-counterfeiting link is as follows:

[0092] First, store the production data of the display link of each gravure water-based ink printing product in JSON in the form of key-value pairs; second, convert the production data in JSON format into Base64 encoding; then, use an online QR code generator to convert the Base64 encoding corresponding to the production data of the display link into a QR code, denoted as the display traceability code; next, use the same method as above to convert the production data of all anti-counterfeiting links of each gravure water-based ink printing product into a QR code, denoted as the anti-counterfeiting traceability code; finally, use ordinary ink printing to write the display traceability code, and special ink printing to write the anti-counterfeiting traceability code. The special ink needs to be identified under specific light conditions or through special methods. Cover the anti-counterfeiting traceability code on the surface of the display traceability code to obtain the product traceability code of each gravure water-based ink printing product.

[0093] It should be noted that the method of converting the production data of the display link and the anti-counterfeiting link of the gravure water-based ink printing product into QR codes is the same. The online QR code generator can be software such as QRStuff and tools such as QRCode Monkey.

[0094] So far, the present invention is completed.
