[0040] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings.

[0041] Figure 1 It is a flowchart of a method for analyzing and processing demand for customized printed products according to the present invention. DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1 As shown, a method for analyzing and processing demand for customized printed products includes:

[0044] Step 1: Collect customer demand information through online platforms; customer demand information includes design preferences, styling preferences, usage scenarios, color choices, size specifications, and quantity requirements;

[0045] Step 2: Define the design plan based on customer demand information, specifically:

[0046] S21: Set up the design set , n represents the maximum number of design solutions;

[0047] S22: According to the customer demand information, identify the cost information in the customer demand information, and establish an n*n demand and cost matrix C accordingly;

[0048] S23: Use exhaustive search algorithms (such as brute force search, backtracking, etc.) to generate all possible design combination sequences ,in, , pi represents the i-th demand element in customer demand information;

[0049] S24: For each design solution, the total cost of the design solution is calculated based on the cost of the design solution sequence contained in the design solution. The formula is: ;

[0050] S25: Obtain the budget range Bmin and Bmax set by the customer, and retain the design scheme whose total cost is within the budget range, that is, satisfying the condition of Bmin≤CP≤Bmax;

[0051] Step 3: Evaluate any design scheme and obtain the design value corresponding to the design scheme; arrange the design schemes in descending order of the design value to obtain a list of design schemes;

[0052] The specific method for evaluating any design solution is as follows:

[0053] S31: Extract the factory time of the printing coating required in the design scheme, calculate the time difference between the factory time and the current time to obtain the factory time, subtract the corresponding factory time from the shelf life of the printing coating to obtain the shelf life, marked as FD1; calculate the shelf life of the printing coating required in the design scheme, using the formula , and obtain the factory impact value FD; where u represents the index of the type of printing coating used in the design, and uFD1 represents the shelf life corresponding to the type of printing coating u. The weight of the shelf life corresponding to the type of printing coating u;

[0054] S32: Obtain the historical usage records of each printing coating, extract the color value of the printing coating at each collection time in the set time zone from the historical usage records, perform similarity calculation on the color value of the printing coating at any collection time and its corresponding standard color value, and obtain a similar value marked as Gk, where k represents the index of the collection time; perform variance calculation on the similar value at any collection time in the set time zone, and use the formula , and obtain the color decay value FG1; where, represents the mean of similar values ​​of all acquisition moments within the set time zone, and Z represents the total number of acquisition moments within the set time zone; calculate the color decay value of all printed coatings in the design scheme, using the formula , and obtain the overall decay value FG; where uFG1 represents the color decay value corresponding to the printing coating of type u, The weight of the color decay value corresponding to the printing coating of type u;

[0055] S33: extracting the estimated design creation time and printing production time in any design solution, wherein the estimated design creation time is obtained by sending an estimated time feedback instruction to the designer's smart terminal; summing up the estimated design creation time and printing production time to obtain a comprehensive estimated time; obtaining the customer's time limit, calculating the time difference between the time limit and the current time to obtain the remaining time; calculating the difference between the comprehensive estimated time and the remaining time, and marking the surplus time as FR;

[0056] S34: The factory impact value, the total decay value, and the margin time are then normalized, and the design value ZF corresponding to the design scheme is obtained using the formula ZF=FD×f1+FG×f2+FR×f3; wherein f1, f2, and f3 represent the weights corresponding to the factory impact value, the total decay value, and the margin time, respectively.

[0057] It should be noted that the corresponding design value is obtained by comprehensively evaluating multiple factors such as the factory delivery time, color decay, estimated design creation time, and printing production time of the printing coating used in the design scheme. This evaluation method takes into account factors such as the quality and stability of the printing coating, the time efficiency of design creation and production, and can more comprehensively and objectively reflect the advantages and disadvantages of the design scheme, providing a strong basis for subsequent scheme selection and optimization.

[0058] Step 4: Conduct customer interaction and design iteration, specifically:

[0059] S41: Feedback the design scheme list to the customer for interactive communication and selection of a design scheme, and obtain design feedback information of the selected design scheme;

[0060] S42: retaining the number of design solutions with the highest evaluation values ​​according to the set solution selection threshold;

[0061] S43; sending the design scheme and the corresponding design feedback information to the designer's smart terminal, the designer receives the design feedback information through the smart terminal, and optimizes its design scheme accordingly to improve its design and obtain an optimized design scheme;

[0062] S44: Feedback the optimized design solution to the customer, and repeat steps S41-S43 until the customer selects the final design solution;

[0063] Step 5: Execute the production process according to the final design plan.

[0064] It should be noted that by comprehensively collecting and analyzing customer demand information, we are able to meet customer needs efficiently and accurately. At the same time, in the process of formulating and optimizing the design plan, we fully consider the cost factors and the customer's budget range to ensure that the design plan not only meets customer expectations, but is also feasible and economical. In addition, through customer interactive communication and design iterations, we continuously improve the design quality so that the final design plan can better meet the customer's personalized requirements and improve customer satisfaction with the design. Finally, we strictly follow the production process to ensure product quality and on-time delivery.

[0065] In the present application, based on step four, the present invention also includes setting an iteration number threshold, extracting the number of times steps S41-43 are repeatedly executed and marking it as the number of re-executions; comparing the number of re-executions with the set iteration number threshold, if the number of re-executions is greater than or equal to the set iteration number threshold, then generating a confirmation strategy and an iterative optimization strategy; the confirmation strategy is used to require the customer to select one of the current design schemes as the final design scheme within a limited time; the iterative optimization strategy is used to evaluate the optimization cost, and the selected design scheme and customer feedback information are sent to the designer's smart terminal, and the designer feeds back the optimization cost based on the customer feedback information, and the optimization cost includes but is not limited to time cost, technical cost and company operating cost; the optimization cost is fed back to the customer, and if the customer agrees, the iteration number threshold is increased by one.

[0066] It should be noted that by setting a threshold for the number of iterations, after a certain number of repeated executions is reached, a confirmation strategy and an iterative optimization strategy are generated to ensure the efficient implementation of the design process. The confirmation strategy ensures that the customer makes a choice within a limited time to avoid unlimited delays; the iterative optimization strategy evaluates the optimization cost and allows the customer to understand the cost impact of further optimization. This method can not only meet customer needs, but also reasonably control the time and cost of the design process. At the same time, the operation of adding one to the threshold for the number of iterations also provides a more flexible processing method for subsequent design iterations.

[0067] In this application, based on step S22, the present invention also includes real-time cost update, specifically:

[0068] Set the update duration. When the update is triggered, collect the cost information corresponding to the current customer demand information and update the demand and cost matrix.

[0069] It should be noted that real-time updates can timely control changes in cost information so that design plans can be better adjusted to adapt to new customer needs, improve design flexibility and adaptability, ensure that the design is more in line with customer expectations, and also help control costs and avoid waste.

[0070] In this application, after updating the demand and cost matrix, the cost changes of the evaluation design solutions are also analyzed, specifically:

[0071] Execute step S24 to obtain the new total cost of the updated design solution; calculate the difference between the new total cost and the total cost before the update to obtain the cost change difference; set an acceptable cost change threshold, if the cost change difference is less than the cost change range, do nothing; if the cost change difference is within the cost change range, feed back the cost information and the cost change difference to the customer, and take corresponding measures based on the customer's feedback.

[0072] It should be noted that by evaluating the cost changes after the design plan is updated, the cost changes can be understood in a timely manner; when the cost change difference is within an acceptable range, a decision is made based on the specific circumstances whether to take further measures; and when the cost change difference exceeds the acceptable range, the relevant information is fed back to the customer so that the customer can make a decision. This processing method helps to ensure the cost rationality of the design plan and customer satisfaction.

[0073] In this application, the present invention also includes:

[0074] Step 6: After the production process is completed, the printed product is audited and analyzed to obtain the printing quality value of the printed product; a quality threshold is set, and the printing quality value is compared with the set quality threshold to generate a corresponding quality processing strategy.

[0075] In this application, the quality audit and analysis of printed products are carried out, specifically:

[0076] The image of the printing area on the printed matter is obtained by a high-definition camera, and the image is enlarged to obtain pixel blocks; the color value of the pixel block is identified; the color value deviation range is set, and the pixel blocks in the color value deviation range are connected to obtain the pixel area; the color value of the pixel blocks in each pixel area is averaged to obtain the area color mean; the area color threshold is set, the area color mean is compared with its area color threshold, and the pixel area whose area color mean is greater than its area color threshold is marked as the color difference area; the number of color difference areas is counted and marked as the number of different colors, which is expressed as YF1; the area of ​​the different color areas is calculated and summed to obtain the color difference face value, which is marked as YF2;

[0077] The color value of any pixel block in the color difference area is calculated by the difference between it and its standard color value, and the color value difference of the pixel block is marked as Yg, where g represents the index of the pixel block; the color value difference of all pixel blocks in the color difference area is calculated, and the formula is used , and obtain the zone difference value YF3; where, Represents the weight of the color value difference corresponding to the pixel block g;

[0078] Normalize the number of heterochromatic colors, color difference values, and area difference values, and use the formula , and obtain the printing quality value YF; where y1, y2, and y3 represent the influencing factors of the number of heterochromatic colors, the color difference face value, and the area difference value on the printing quality of the printed product respectively; set a quality threshold, if the printing quality value is greater than or equal to its quality threshold, no processing is performed; on the contrary, if the printing quality value is less than its quality threshold, it means that the quality of the printed product is unqualified, and a reprinting strategy is generated; the reprinting strategy is used to trigger the production process to increase the number of prints by one.

[0079] It should be noted that the quality of printed products is comprehensively and accurately evaluated through the quality audit steps; from acquiring images, identifying color values, dividing color difference areas, calculating various indicators, to normalization processing and comparison with quality thresholds, it is possible to effectively discover possible quality problems in printed products and take corresponding measures based on the results, ensuring the quality stability and consistency of printed products while protecting the rights and interests of customers.
