Description

Technical Field

[0001] The invention relates to the technical field of anti-counterfeiting, and in particular to an anti-counterfeiting tracing method for production information of gravure water-based ink printing. Background Art

[0002] The anti-counterfeiting and traceability technology of gravure water-based ink printing ensures that each product can be accurately located and traced throughout its life cycle by recording and tracking each link in the production process. It involves 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 the products.

[0003] Existing methods usually select production information of key production links in the product production process to generate traceability codes, randomly select information of other production links to generate anti-counterfeiting codes, and obtain product traceability codes by combining them; however, since the randomly selected production links of the anti-counterfeiting codes have a poor degree of correlation with the key production links, the anti-counterfeiting codes miss key data in the production process and the traceability chain may be incomplete, thereby 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 and the key production links in the production process of randomly selected products is poor, and the accuracy and security of the traceability code are reduced, the purpose of the present invention is to provide an anti-counterfeiting and traceability method for gravure water-based ink printing production information, and the technical scheme adopted is as follows: The present invention proposes an anti-counterfeiting and tracing method for gravure water-based ink printing production information, the method comprising: Obtain the final quality score sequence of the same batch of gravure water-based ink printing products and the link quality score sequence in the same production link; According to the correlation and difference between the link quality score sequences of each production link and the other production links of the gravure water-based ink printing products, the strongly correlated links of each production link are screened; According to the correlation between the link quality score sequence of each production link and the final quality score sequence, as well as the discrete degree of the elements in the link quality score sequence, the final quality contribution of each production link is obtained; According to the correlation between the link quality score sequence of each production link and each of its strongly associated links and the final quality score sequence and the final quality contribution, the correlation between each production link and each of its strongly associated links is adjusted, and the strongly associated links in the same direction of each production link are screened; According to the final quality contribution of the strongly associated links in the same direction of the production link, the display link and the anti-counterfeiting link are determined, and a product traceability code is generated based on the production data of the display link and the anti-counterfeiting link of each gravure water-based ink printing product.

[0005] Furthermore, the screening of strongly related links in each production link includes: Determine the quality analysis element of each element in the link quality scoring sequence of each production link; obtain the overall quality degradation index of each production link based on the differences between all elements in the link quality scoring sequence of each production link and its quality analysis element; Obtain the correlation coefficient of the link quality score sequence of each production link with the remaining production links; obtain the link correlation degree of each production link with the remaining production links according to the difference of the overall quality degradation index of each production link with the remaining production links and the correlation coefficient; Based on the link correlation, the strongly correlated links of each production link are selected.

[0006] Furthermore, the screening of strongly associated links in the same direction of each production link includes: Obtaining the interference coefficient between each production link and each of its strongly associated links according to the correlation between the link quality score sequence of all production links between each production link and each of its strongly associated links and the final quality score sequence and the final quality contribution; The interference coefficient is used to adjust the link correlation between each production link and each of its strongly associated links to obtain a revised correlation between each production link and each of its strongly associated links; based on the revised correlation, strongly associated links in the same direction are selected from the strongly associated links of each production link.

[0007] Furthermore, the determination of the display link and the anti-counterfeiting link includes: Calculate the average of the final quality contribution of all the strongly associated links in the same direction of each production link as the associated contribution of each production link; select the production link corresponding to the maximum value of the associated contribution of all production links of gravure water-based ink printing products, and record it as the traceability link; For the traceability link and all its strongly associated links in the same direction, the link corresponding to the largest final quality contribution is used as the display link, and the remaining links are used as anti-counterfeiting links.

[0008] Furthermore, obtaining the final quality contribution of each production link includes: Obtain the correlation coefficient between the link quality score sequence of each production link and the final quality score sequence; The variance of the elements in the link quality score sequence of each production link is negatively mapped, and 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 is used as the final quality contribution of each production link.

[0009] Furthermore, the obtaining of the overall quality degradation index of each production link includes: Calculate the absolute value of the difference between each element in the link quality score sequence of each production link and the mean of all its quality analysis elements as the local quality degradation index of each element; take the mean of the local quality degradation indicators of all elements in the link quality score sequence of each production link as the overall quality degradation index of each production link.

[0010] Furthermore, the obtaining of the interference coefficient between each production link and each of its strongly associated links includes: The cumulative sum of the product of the link quality score sequence of all production links between each production link and each of its strongly associated links and the correlation coefficient of the final quality score sequence and the final quality contribution is used as the interference coefficient between each production link and each of its strongly associated links.

[0011] Furthermore, the step of obtaining the corrected correlation between each production link and each of its strongly correlated links includes: The interference coefficient is negatively correlated and normalized, and based on the processing result, the link correlation between each production link and each of its strongly associated links is weighted to obtain a corrected correlation between each production link and each of its strongly associated links.

[0012] Furthermore, each element in the link quality score sequence is not equal to the corresponding element of its quality analysis element in the final quality score sequence.

[0013] Furthermore, the correlation coefficient is a Pearson correlation coefficient.

[0014] The present invention has the following beneficial effects: In an embodiment of the present invention, in order to avoid leaking too much key production data in the product traceability code, the production mode in the production link is extracted, and a unique production logic for ink printing products is generated, specifically: the degree of correlation and difference between the link quality score sequences of each production link and the other production links, the degree of correlation of different production links is analyzed in turn from the quality-related aspects and chain reaction aspects, and the strongly correlated links are selected; based on the degree of correlation between different production links, the key information in the production process is determined to obtain the final quality contribution of the production quality; since the quality fluctuations of the production links between each production link and its strongly correlated links may interfere with or change the degree of correlation between the corresponding two production links, it is necessary to use the quality changes of the intermediate production links to adjust the degree of correlation between each production link and each of its strongly correlated links, so as to better cope with the changes that may occur in the production process and improve the accuracy of the strongly correlated links in the same direction; determine the key display links in the product production process and the anti-counterfeiting links with a strong degree of correlation, 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 improving traceability security.

DETAILED DESCRIPTION

[0017] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the anti-counterfeiting traceability method of gravure water-based ink printing production information proposed by the present invention, its specific implementation method, structure, characteristics and effects as follows in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0018] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0019] The specific scheme of the anti-counterfeiting and tracing method for gravure water-based ink printing production information provided by the present invention is described in detail below with reference to the accompanying drawings.

[0020] Embodiment 1: The present invention proposes an anti-counterfeiting and tracing method for production information of gravure water-based ink printing. Figure 1 , which shows a flowchart of steps of an anti-counterfeiting and tracing method for gravure water-based ink printing production information provided by an embodiment of the present invention, the method comprising: Step S1: obtaining a final quality score sequence of the same batch of gravure water-based ink printing products and a link quality score sequence in the same production link.

[0021] The production process of gravure water-based ink printing products is, in order, raw material preparation, ink mixing, gravure printing, drying and curing, and packaging and shipping. Combined with integrated sensors and manual data recording, the production data of each production process of the same batch of gravure water-based ink printing products in the ink printing process is collected, as follows: The production data of the raw material preparation stage includes: the batch number of the raw materials, supplier information and production date; the production data of the ink preparation stage includes: the ratio of pigment and solvent, the temperature and humidity during the preparation process; the production data of the gravure printing stage includes: the temperature, pressure and humidity of the production equipment during the printing process, the amount, quality and viscosity of the ink used; the production data of the drying and curing stage includes: the drying temperature and wind speed; the production data of the packaging and shipping stage includes: the production batch number, packaging information and logistics tracking information.

[0022] Blockchain technology is used to store production data of each production link of gravure water-based ink printing products to ensure data persistence, non-tamperability and high availability.

[0023] All production data of each production link of each gravure water-based ink printing product is input into the trained neural network, and the neural network outputs a score between 0 and 1, which is recorded as the link quality score of the corresponding production link. The total color difference of each gravure water-based ink printing product is collected in turn using a colorimeter and a densitometer , ink concentration. The smaller the total color difference and the greater the ink concentration, the clearer the printed product and the better the quality. The total color difference and ink concentration of each gravure water-based ink printed product are normalized respectively, and the difference between the constant 1 and the normalized total color difference and the average of the normalized ink concentration are used as the final quality score of each gravure water-based ink printed product.

[0024] The link quality scores of the same production link of all gravure water-based ink printing products of the same batch are arranged in order to form a link quality score sequence for each production link; the final quality scores of all gravure water-based ink printing products of the same batch are arranged in order to form a final quality score sequence.

[0025] It should be noted that the elements with the same subscript in the quality score sequence of all links 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 the same batch of gravure water-based ink printing products.

[0026] Step S2: According to the correlation degree and difference between the link quality score sequences of each production link and the other production links of the gravure water-based ink printing products, the strongly associated links of each production link are screened.

[0027] There is a strong correlation between different production links in the production process of gravure water-based ink printing products. The production links with a strong correlation will produce a chain reaction. For example, the ratio of pigment and solvent in the ink mixing 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 ink mixing link and the drying and curing link are highly correlated.

[0028] The correlation degree between the link quality score sequence of each production link and the other production links directly presents the correlation degree of different production links; the link quality score sequence represents the quality situation of each production link, and the difference between the link quality score sequence of each production link and the other production links presents the possibility that the quality change of each production link and the other production links is caused by a chain reaction; the comprehensive analysis of the two factors can effectively improve the accuracy of the correlation degree between each production link and the other production links, so as to select the strongly correlated links with a strong correlation degree with each production link.

[0029] See also Figure 2 , which shows a flowchart of a method for obtaining a strongly associated link provided by an embodiment of the present invention, the method comprising: Step S210: Determine the quality analysis element of each element in the link quality scoring sequence of each production link; obtain the overall quality degradation index of each production link according to the differences between all elements in the link quality scoring sequence of each production link and its quality analysis element.

[0030] 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 real impact of each production link on other links. Therefore, when analyzing the impact of a single production link on the quality of printed products, the link quality scores of ink printing products with different final quality scores in the same production link are screened for analysis to obtain the quality analysis elements of each element. In one implementation of an embodiment of the present invention, each element in the link quality score sequence is not equal to the corresponding element of its quality analysis element in the final quality score sequence. It should be noted that the subscript of each element in the link quality score sequence is equal to the subscript of the corresponding element in the final quality score sequence.

[0031] In a specific implementation of the embodiment of the present invention, the specific method for obtaining the overall quality degradation index is: calculating the absolute value of the difference between each element in the link quality scoring sequence of each production link and the mean of all its quality analysis elements as the local quality degradation index of each element; taking the mean of the local quality degradation index of all elements in the link quality scoring sequence of each production link as the overall quality degradation index of each production link. The overall quality degradation index E of each production link is expressed by the formula: Where 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 for 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; The local quality degradation index of the nth element in the link quality scoring sequence for each production link; is the absolute value function. It should be noted that Represents the standard production level of each production link. The larger it is, the more significant the production precision error of the ink printing product corresponding to the nth element in the link quality score sequence of each production link is in this production link, the greater the impact of this production link on the subsequent production links, the more serious the production quality deterioration of this production link is, and the larger the overall quality degradation index E is.

[0032] Step S220: Obtain the correlation coefficient of the link quality score series of each production link with the remaining production links; obtain the link correlation degree of each production link with the remaining production links according to the difference and correlation coefficient of the overall quality degradation index of each production link with the remaining production links.

[0033] In a specific implementation of the embodiment of the present invention, the link correlation is expressed by the formula: In the formula, is the link correlation between the u-th production link and the remaining v-th production links; is the link quality score sequence of the u-th production link; is the link quality score sequence of the vth production link except the uth production link; is the correlation coefficient between the u-th production link and the remaining v-th production links; is the overall quality degradation index of the u-th production link; is the overall quality degradation index of the vth production link except the uth production link; is the absolute value function; Norm is the normalization function. It should be noted that if The larger is, the stronger the correlation between the u-th production link and the remaining v-th production links; because the link quality of the production links with a strong correlation will produce a chain reaction, that is, if a production link has a quality problem, the production links with a strong correlation will also have quality problems, so if The smaller it is, the greater the possibility that the change in production quality between the u-th production link and the remaining v-th production link is caused by a chain reaction, and the stronger the correlation between the two production links. The bigger.

[0034] In one implementation of the present invention, the correlation coefficient is a Pearson correlation coefficient; in other embodiments of the present invention, the correlation coefficient may also be a Spearman correlation coefficient, a Kendall rank correlation coefficient, a canonical correlation coefficient, etc. The correlation coefficients at other positions in the specification are the same as those selected here.

[0035] Step S230: Based on the link correlation, select the strongly correlated links of each production link.

[0036] The greater the link correlation between each production link and the other production links, the greater the correlation between each production link and the other production links. In one implementation of the embodiment of the present invention, for the link correlation between each production link and the other production links, the production link corresponding to the link correlation greater than the preset correlation threshold is taken as the strongly correlated link of each production link.

[0037] In an implementation of the embodiment of the present invention, the preset correlation threshold is set to 0.7, and the implementer can set it according to the specific situation.

[0038] Step S3: According to the correlation between the link quality score sequence of each production link and the final quality score sequence, and the discrete degree of the elements in the link quality score sequence, the final quality contribution of each production link is obtained.

[0039] Due to the differences in gravure water-based ink printing technology and product requirements, the quality of different production links of gravure water-based ink printing products has different degrees of influence on the final quality score. The discrete degree of the elements in the link quality score sequence reflects the accuracy required for production data in each production link, which in turn affects product quality. Combined with the correlation between the link quality score sequence of each production link and the final quality score sequence, the importance of each production link to product quality is analyzed to obtain the final quality contribution.

[0040] In one implementation of the present invention, the method for obtaining the final quality contribution is: obtaining the correlation coefficient between the link quality score sequence of each production link and the final quality score sequence; performing negative correlation mapping on the variance of the elements in the link quality score sequence of each production link, and taking 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 of each production link. The final quality contribution is expressed by the formula: In the formula, is the final quality contribution 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. Function pair Negative correlation mapping is performed. It should be noted that if The smaller it is, the more stable the production data of the u-th production link is during the printing process, and the higher the production link's requirement for production data accuracy is, indicating that the u-th production link contributes more to the quality of gravure water-based ink printing products. The bigger; if The larger the value is, the greater the impact of the u-th production link on product quality, and the greater the contribution of the u-th production link to product quality. The bigger.

[0041] Step S4: According to the correlation between the link quality score sequence of each production link and each of its strongly associated links and the final quality score sequence and the final quality contribution, adjust the correlation between each production link and each of its strongly associated links, and screen the strongly associated links in the same direction of each production link.

[0042] There may be multiple production links between each production link and each of its strongly associated links. If the intermediate production links can significantly affect the quality of ink printing products, the quality fluctuations of the intermediate production links may interfere with or change the degree of association between each production link and each of its strongly associated links. The correlation between the link quality score sequence and the final quality score sequence of the production link and the final quality contribution can both reflect the degree of influence of the production link on product quality. The degree of association between each production link and each of its strongly associated links is adjusted by using two factors, and then the strongly associated links in the same direction are determined.

[0043] See also Figure 3 , which shows a flowchart of a method for acquiring strongly associated links in the same direction provided by an embodiment of the present invention, the method comprising: Step S410: Obtain the interference coefficient between each production link and each of its strongly associated links according to the correlation between the link quality score sequence of all production links between each production link and each of its strongly associated links and the final quality score sequence and the final quality contribution.

[0044] In one implementation of the embodiment of the present invention, the interference coefficient is obtained by taking the product of the correlation coefficient of the link quality score sequence of all production links between each production link and each of its strongly associated links and the final quality score sequence and the final quality contribution as the interference coefficient between each production link and each of its strongly associated links. The interference coefficient is expressed by the formula: 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 of the mth production link between the uth production link and its cth strongly associated link; is the link quality score sequence of the mth production link between the uth production link and its cth strongly associated link; ZX is the final quality score sequence; is the correlation coefficient between the link quality score sequence of the mth production link and the final quality score sequence between the uth production link and its cth strongly associated link. It should be noted that if and The larger the mth production link is, the greater the impact of the mth production link on the product quality. The greater the interference degree of the mth production link on the correlation between the uth production link and its cth strongly correlated link is, the greater the interference coefficient is. The bigger.

[0045] Step S420: Use the interference coefficient to adjust the link correlation between each production link and each of its strongly associated links, and obtain the corrected correlation between each production link and each of its strongly associated links; based on the corrected correlation, select the strongly associated links in the same direction from the strongly associated links of each production link.

[0046] The correlation degree between each production link and each of its strongly associated links presents the correlation degree between the corresponding two production links. If the interference degree between the two production links is greater, the correlation degree between each production link and each of its strongly associated links will be weakened, and the corrected correlation degree will be smaller.

[0047] In one implementation of the embodiment of the present invention, the method for obtaining the corrected correlation is: negatively correlate and normalize the interference coefficient, and based on the processing result, weight the correlation between each production link and each of its strongly associated links to obtain the corrected correlation between each production link and each of its strongly associated links. The corrected correlation is expressed by the formula: In the formula, is the modified correlation between the u-th production link and its c-th strongly associated link; is the link correlation 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.

[0048] The greater the corrected correlation between each production link and each of its strongly associated links, the greater the correlation between the two corresponding production links. In one implementation of the embodiment of the present invention, for the corrected correlation between each production link and all of its strongly associated links, the strongly associated links corresponding to the corrected correlations greater than the preset same-direction correlation threshold are taken as the same-direction strongly associated links of each production link.

[0049] In an 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 the specific situation.

[0050] Step S5: Determine the display link and the anti-counterfeiting link according to the final quality contribution of the same-direction strongly associated links in 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 printing product.

[0051] In order to avoid leaking too much key production data in the product traceability code, it is necessary to extract production information with anti-counterfeiting significance during the production process of gravure water-based ink printing products, extract specific production patterns in the production link, generate a unique production logic for ink printing products, determine the display link and anti-counterfeiting link, strengthen the anti-counterfeiting effect and improve traceability security.

[0052] Preferably, in some possible implementations of the embodiments of the present invention, the method for obtaining the display link and the anti-counterfeiting link is: calculate the average of the final quality contribution of all the links strongly associated in the same direction of each production link as the associated contribution of each production link; select the production link corresponding to the maximum value of the associated contribution of all the production links of the gravure water-based ink printing product, and record it as the traceability link; for the traceability link and all its links strongly associated in the same direction, the link corresponding to the maximum final quality contribution is respectively used as the display link, and the remaining links are used as the anti-counterfeiting link. The production link with the maximum associated contribution is the most important for the gravure water-based ink printing product. This production link is used as the protection object and display object of the product, and the production data of the links strongly associated in the same direction with the production link are included in the anti-counterfeiting information, thereby strengthening the anti-counterfeiting effect and improving the traceability security.

[0053] The specific process of generating product traceability codes based on production data from the display and anti-counterfeiting stages is as follows: Firstly, the production data of the display link of each gravure water-based ink printing product is stored in JSON in the form of key-value pairs; secondly, the production data in JSON format is converted into Base64 code; then, the Base64 code corresponding to the production data of the display link is converted into a QR code using an online QR code generator, which is recorded as the display traceability code; then, the production data of all anti-counterfeiting links of each gravure water-based ink printing product is converted into a QR code using the same method as above, which is recorded as the anti-counterfeiting traceability code; finally, the display traceability code is written by ordinary ink printing, and the anti-counterfeiting traceability code is written by special ink printing. The special ink needs to be identified under specific lighting conditions or by special methods. The anti-counterfeiting traceability code is covered on the surface of the display traceability code to obtain the product traceability code of each gravure water-based ink printing product.

[0054] 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 a QR code is the same. Online QR code generators can be QRStuff software and QRCode Monkey tools.

[0055] So far, the present invention is completed.

[0056] Embodiment 2: The present invention proposes an anti-counterfeiting and traceability system for gravure water-based ink printing production information.

The traceability code generation module 650 is used to determine the display link and the anti-counterfeiting link according to the final quality contribution of the same-direction strongly associated links in 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 printing product.
