Description

Technical Field

[0001] This invention relates to the field of hot stamping printing technology, and in particular to a method and system for controlling the amount of hot stamping film used. Background Technology

[0002] Hot stamping is a process in which a hot stamping machine applies hot stamping foil (such as electroplated aluminum foil) to the surface of a substrate under specific temperature and pressure. It allows for the printing of patterns, text, and lines to highlight product names, trademarks, anti-counterfeiting designs, etc., thereby enhancing the appearance of product packaging. For example... Figure 1 As shown, during hot stamping, the electroplated aluminum foil is on top of the paper. 1-5 hot stamping blocks can be set as needed, and the distance between each hot stamping block and the pattern on the hot stamping block can be different. The hot stamping blocks are heated by a heating plate and moved downwards to press the hot stamping blocks onto the paper. The pressure and high temperature between the moving platform and the heating plate press the pattern on the electroplated aluminum foil onto the paper.

[0003] However, in existing hot stamping methods, the paper and electroplated aluminum foil are fed synchronously at a constant speed to ensure the hot stamping effect. But most packaging products only require hot stamping on a portion of the packaging area. If the electroplated aluminum foil is fed synchronously with the paper, a lot of electroplated aluminum foil material will be wasted. Therefore, reasonable control of the amount of electroplated aluminum foil used is crucial for saving costs and improving production efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a method and system for controlling the amount of hot stamping film used, so as to solve the problem of waste caused by unreasonable use of hot stamping film.

[0005] The technical solution of the present invention is as follows:

[0006] This invention provides a method and system for controlling the amount of hot stamping film used, comprising:

[0007] Obtain the parameters of the hot stamping pattern;

[0008] Calculate the optimal number of steps, optimal step distance, and amount of hot stamping film based on the hot stamping pattern parameters.

[0009] During hot stamping, the actual amount of hot stamping film used is monitored in real time, and the utilization rate of hot stamping film is calculated based on the monitoring results.

[0010] The hot stamping pattern parameters include: the number of hot stamping blocks, the width of the hot stamping blocks, the spacing between adjacent hot stamping blocks, and the spacing between the hot stamping blocks when walking.

[0011] After calculating the optimal number of steps and jump distance for the hot stamping film based on the hot stamping pattern parameters, the method further includes:

[0012] The hot stamping process is simulated based on the optimal number of steps and jump distance, and pattern overlap detection and empty areas are recorded.

[0013] When overlapping hot stamping patterns are detected, adjust the optimal number of steps and / or jump distance before simulating hot stamping again.

[0014] After the steps of monitoring the actual amount of hot stamping film used in real time during hot stamping and calculating the utilization rate of hot stamping film based on the monitoring results, the method further includes:

[0015] Determine whether the utilization rate of the hot stamping film is equal to or higher than a preset threshold;

[0016] When the utilization rate of the hot stamping film is higher than the preset threshold, the hot stamping film is delivered according to the optimal number of steps and the optimal jump distance.

[0017] After the steps of monitoring the actual amount of hot stamping film used in real time during hot stamping and calculating the utilization rate of hot stamping film based on the monitoring results, the method further includes:

[0018] When the utilization rate of the hot stamping film is lower than the preset threshold, the optimal number of steps and the jump distance are evaluated or adjusted as the optimal number of steps and the jump distance for the next hot stamping.

[0019] When the widths of the hot stamping blocks are equal and the spacing between adjacent hot stamping blocks is equal:

[0020] Optimal number of steps N = P ÷ G

[0021] Optimal jump distance M = (X-1)×P + X×W + H

[0022] Where X is the number of hot stamping blocks, P is the spacing between adjacent hot stamping blocks, W is the width of the hot stamping blocks, H is the spacing between the hot stamping blocks when walking, G is the step distance, G = W + H, and the optimal number of steps is rounded down to the nearest integer.

[0023] When the widths of the hot stamping blocks are not equal, but the spacing between adjacent hot stamping blocks is equal:

[0024] Optimal number of steps N = P ÷ G

[0025] Optimal jump distance M = (X-1)×P + ∑W x +H

[0026] Where X is the number of hot stamping blocks, P is the spacing between adjacent hot stamping blocks, W is the width of the hot stamping blocks, H is the spacing between the hot stamping blocks during walking, and G is the step distance, G = W max +H, W max Take the widest one among the hot stamping blocks, and round down to the nearest integer for the optimal number of steps. The hot stamping cycle jump distance Y = N × G + M.

[0027] When the widths of the hot stamping blocks are equal and the spacing between adjacent hot stamping blocks is unequal:

[0028] Optimal number of steps N = P min ÷G

[0029] Optimal jump distance M = (X-1)×P + ∑P y +H

[0030] Where X is the number of hot stamping blocks, P is the spacing between adjacent hot stamping blocks, and P min H is the minimum distance between adjacent hot stamping blocks, and G is the distance between hot stamping blocks during the step. G = W + H, where W is the width of the hot stamping block. The optimal number of steps is rounded down to the nearest integer.

[0031] When the widths of the hot stamping blocks are not equal and the spacing between adjacent hot stamping blocks is not equal, the number of steps and the step distance are calculated according to the following formula:

[0032] The first step distance S1 = W max +H;

[0033] Number of steps N(S1) = P1 ÷ S1

[0034] Second step distance S2=a+H

[0035] The number of small jumps N(S2) = P2 ÷ (S2 + N(S1) × S1) + N(S1) × S1

[0036] Third step distance S3=K+H'

[0037] Aluminum foil follows the following sequential step-by-step formula:

[0038] N(S2)[N(S1)×S1+S2]+S3 (N(S2) is at least equal to 1; if it is less than 1, the loop skipping step is N(S1)×S1+S3)

[0039] In this context, the number of steps N(S1) and the number of small jumps N(S2) are both rounded down to the nearest integer. X is the number of hot stamping blocks, P1 is the distance between the first and second hot stamping blocks, P2 is the distance between the second and third hot stamping blocks, and P2 > P1. max H represents the width of the widest hot stamping block, H represents the spacing between hot stamping blocks during walking and small jumps, H' represents the spacing between hot stamping blocks during large jumps, K represents the distance from the first hot stamping pattern to the end of the last hot stamping pattern, and a represents the distance between the first hot stamping pattern and the second hot stamping pattern.

[0040] The present invention also provides a hot stamping film material usage control system, characterized in that it includes:

[0041] The pattern acquisition module is used to acquire the parameters of the hot stamping pattern;

[0042] The usage calculation module is used to calculate the optimal number of steps, the optimal step distance, and the amount of hot stamping film used based on the hot stamping pattern parameters.

[0043] The monitoring module is used to monitor the actual amount of hot stamping film used in real time, and calculate whether the utilization rate of hot stamping film is equal to or higher than the preset threshold based on the monitoring results.

[0044] The hot stamping control module is used to monitor the actual amount of hot stamping film used in real time during hot stamping and to calculate the utilization rate of hot stamping film based on the monitoring results.

[0045] Beneficial effects: This invention obtains the hot stamping pattern parameters in advance, and calculates the optimal number of steps, optimal jump distance, and amount of hot stamping film based on the hot stamping pattern parameters. During hot stamping, the actual amount of hot stamping film used is monitored in real time, and the utilization rate of hot stamping film is calculated based on the monitoring results, thereby improving the utilization rate of hot stamping film, reducing waste of hot stamping film, and saving material costs.

[0054] To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention is further described in detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0055] This invention provides an intelligent hot stamping production management method, which includes multiple modules and can be used for hot stamping process management. Please refer to [link / reference]. Figure 2 The hot stamping film usage control method provided in this embodiment of the invention includes:

[0056] S10. Obtain the hot stamping pattern parameters.

[0057] S20. Calculate the optimal number of steps, optimal step distance, and amount of hot stamping film based on the hot stamping pattern parameters.

[0058] S30. During hot stamping, monitor the actual amount of hot stamping film used in real time, and calculate the utilization rate of hot stamping film based on the monitoring results.

[0059] The hot stamping pattern parameters include: the number of hot stamping blocks, the width of each hot stamping block, the spacing between adjacent hot stamping blocks, and the spacing between hot stamping blocks when walking.

[0060] In one embodiment, the hot stamping machine is provided with 2-5 hot stamping blocks. The patterns on each hot stamping block can be the same or different, and the width of the hot stamping blocks and the spacing between each hot stamping block can be the same or different.

[0061] This invention can import hot stamping design patterns and analyze them to identify key parameters such as the spacing between hot stamping patterns and the size of the hot stamping patterns. By automatically converting graphic data into computer-understandable parameters, it provides an accurate and efficient foundation for the subsequent printing and hot stamping process, and the parameter acquisition efficiency is high.

[0062] In another alternative embodiment, when obtaining hot stamping pattern parameters, the hot stamping sample can be directly scanned to identify the hot stamping pattern in the sample, and the size and spacing of the hot stamping pattern can be automatically calculated to obtain the required hot stamping pattern parameters and import them. Through the digital processing of existing samples, the acquisition of hot stamping pattern parameters becomes convenient, while ensuring the accuracy and consistency of the imported parameters.

[0063] Of course, the hot stamping pattern parameters can also be manually entered by the operator, and this invention does not impose any restrictions on this. This invention simplifies the workflow for obtaining hot stamping pattern parameters by importing the hot stamping design pattern and automatically recognizing the hot stamping sample, thereby improving efficiency and making the control method more intelligent and flexible.

[0064] In step S20, the hot stamping film material can be electroplated aluminum foil. According to different parameters of the hot stamping pattern, such as size, shape, and spacing, a suitable calculation method can be flexibly selected to calculate the optimal number of steps and the optimal jump distance, so as to optimize the utilization efficiency of the hot stamping film material.

[0065] In practical implementation, the present invention needs to intelligently select the most suitable calculation method for the amount of electroplated aluminum based on the hot stamping pattern parameters. Considering that different shapes and sizes of patterns may require different calculation formulas, the present invention can flexibly cope with various situations to optimize the efficiency of electroplated aluminum usage.

[0066] In the first embodiment, when the widths of the hot stamping blocks are equal and the spacing between adjacent hot stamping blocks is equal, the optimal number of steps and the optimal jump distance are calculated using the following formulas:

[0067] Optimal number of steps N = P ÷ G

[0068] Optimal jump distance M = (X-1)×P + X×W + H

[0069] Where X is the number of hot stamping blocks, P is the spacing between adjacent hot stamping blocks, H is the spacing between hot stamping blocks during the step, which can also be understood as the spacing between two patterns on the electroplated aluminum foil during the step, G is the step distance, G = W + H, W is the width of the hot stamping block, the optimal number of steps is rounded down to the integer, and the hot stamping cycle jump distance is Y = N × G + M.

[0070] Please see Figure 3 In one specific embodiment, it is assumed that the number of hot stamping blocks X is 4, the width W of each hot stamping block is 30mm, the spacing P between each hot stamping block is equal and is 120mm, and the spacing H between two patterns on the hot stamping film is 2mm during hot stamping.

[0071] pass Figure 3 As can be seen, the first step involves pressing the hot stamping block down onto the first printed material (such as the first sheet of paper) using existing hot stamping methods, and then resetting it. Afterward, the hot stamping film can move around. (For ease of differentiation...) Figure 3 The gray circle indicates the area where the hot stamping film is used after the first hot stamping step.

[0072] In the second step, the rewinding servo motor causes the hot stamping film to move once, and the distance of each move is G = W + H = 30 + 2 = 32 mm;

[0073] The number of steps N = P ÷ G = 120 ÷ 32 = 3.75. Using the floor method, the optimal number of steps is 3.

[0074] And the optimal jump distance M = (X-1)×P + X×W + H = 482mm, in the first jump, if Figure 3As shown in the fifth step, the cyclic jump distance is Y = N × G + M = 578 mm. That is, in this embodiment, the cyclic jump distance is the sum of the distance of walking 3 times and the jump distance, which is the distance of each jump.

[0075] Please see Figure 4 In the second embodiment of the present invention, when the widths of the hot stamping blocks are not equal and the spacing between adjacent hot stamping blocks is equal:

[0076] Optimal number of steps N = P ÷ G

[0077] Optimal jump distance M = (X-1)×P + ∑W x +H

[0078] Where X is the number of hot stamping blocks, P is the distance between adjacent hot stamping blocks, H is the distance between hot stamping blocks during walking, and G is the step distance, G = W max +H, W is the width of the hot stamping block, W max Take the widest one among the hot stamping blocks, and round down to the nearest integer for the optimal number of steps. The hot stamping cycle jump distance Y = N × G + M.

[0079] Please see Figure 4 In one specific embodiment, assuming the number of hot stamping blocks X is 4, the width W1 of the first hot stamping block A1 is 30mm, the width W2 of the second hot stamping block B1 is 50mm, the width W3 of the third hot stamping block C1 is 30mm, and the width W4 of the fourth hot stamping block D1 is 50mm, the spacing P between them is equal and 120mm, and the spacing H between two patterns is 2mm when the hot stamping film moves, it can be according to... Figure 4 The third step is to perform hot stamping.

[0080] pass Figure 4 As can be seen, the first step is to directly use the existing hot stamping method to press the hot stamping block down onto the first printed product (such as the first sheet of paper) and then reset it.

[0081] In the second step, the rewinding servo motor causes the hot stamping film to move once, and the distance of each move is G = W2 (or W4) + H = 50 + 2 = 52 mm;

[0082] The number of steps N = P ÷ G = 120 ÷ 52 ≈ 2.31. Using the floor method, the optimal number of steps is 2.

[0083] And the optimal jump distance M = (X-1)×P + ∑W x +H=522mm, during the first jump, if Figure 3 The arrow in the third step indicates the jump step, and its cyclic jump step distance is Y=N×G+M=626mm. That is, in this embodiment, the cyclic jump step distance is the sum of the distance of walking twice and the jump step distance, that is, the distance of each jump step.

[0084] Please see Figure 5 In the third embodiment of the present invention, when the widths of the hot stamping blocks are equal and the spacing between adjacent hot stamping blocks is unequal:

[0085] Optimal number of steps N = P min ÷G

[0086] Optimal jump distance M = (X-1)×P + ∑P y +H

[0087] Where X is the number of hot stamping blocks, P is the spacing between adjacent hot stamping blocks, and P min H is the minimum distance between adjacent hot stamping blocks, and G is the distance between hot stamping blocks during the step. G = W + H, where W is the width of the hot stamping block. The optimal number of steps is rounded down to the nearest integer. The hot stamping cycle jump distance Y = N × G + M.

[0088] Please see Figure 5 In one specific embodiment, assuming the number of hot stamping blocks X is 4, the width W of the hot stamping blocks is 30mm, the spacing between them Pab is 105mm, Pbc is 140mm, Pcd is 120mm, and the spacing H between the two patterns is 2mm during the step, it can be calculated according to... Figure 5 The hot stamping process is carried out using the steps described in the text.

[0089] pass Figure 5 As can be seen, the first step is to directly use the existing hot stamping method to press the hot stamping block down onto the first printed product (such as the first sheet of paper) and then reset it.

[0090] In the second step, the rewinding servo motor causes the hot stamping film to move once, and the distance of each move is G = W + H = 30 + 2 = 32 mm;

[0091] The number of steps N = P ÷ G = 105 ÷ 32 ≈ 3.28. Using the floor method, the optimal number of steps is 3.

[0092] And the optimal jump distance M = ∑P y +X×30+H=487mm, during the first jump, if Figure 5 The arrow in step 5 indicates the jump step, and its cyclic jump step distance is Y=N×G+M=583mm. That is, in this embodiment, the cyclic jump step distance is the sum of the distance of 3 walking steps and the jump step distance, that is, the distance of each jump step.

[0093] Please see Figure 6 In the fourth embodiment of the present invention, when the widths of the hot stamping blocks are not equal and the spacing between adjacent hot stamping blocks is not equal, the number of steps and the step distance are calculated according to the following formula:

[0094] The first step distance S1 = Wmax +H;

[0095] Number of steps N(S1) = P1 ÷ S1

[0096] Second step distance S2=a+H

[0097] The number of small jumps N(S2) = P2 ÷ (S2 + N(S1) × S1) + N(S1) × S1

[0098] Third step distance S3=K+H'

[0099] Aluminum foil follows the following sequential step-by-step formula:

[0100] N(S2)[N(S1)×S1+S2]+S3 (N(S2) is at least equal to 1. If it is less than 1, the loop skipping step is N(S1)×S1+S3).

[0101] In this context, the number of steps N(S1) and the number of small jumps N(S2) are both rounded down to the nearest integer. X is the number of hot stamping blocks, P1 is the distance between the first and second hot stamping blocks, P2 is the distance between the second and third hot stamping blocks, and P2 > P1. max H represents the width of the widest hot stamping block, H represents the spacing between hot stamping blocks during walking and small jumps, H' represents the spacing between hot stamping blocks during large jumps, K represents the distance from the first hot stamping pattern to the end of the last hot stamping pattern, and a represents the distance between the first hot stamping pattern and the second hot stamping pattern.

[0102] Please see Figure 6 In one specific embodiment, the width W1 of the first hot stamping block is 20mm, the width W2 of the second hot stamping block is 15mm, the distance P1 between them is 85mm, the distance P2 between the second and third hot stamping blocks is 460mm, the distance P3 between the third and fourth hot stamping blocks is 85mm, the distance H between the two patterns is 2mm when walking, and the distance H' between the two patterns is 3mm when jumping. The distance K from the first hot stamping pattern to the end of the last hot stamping pattern is 700mm, and the distance a between the first hot stamping pattern and the second hot stamping pattern is 120mm; it can be arranged according to... Figure 6 The hot stamping process is carried out using the steps described in the text.

[0103] pass Figure 6 As can be seen, the first step is to directly use the existing hot stamping method to press the hot stamping block down onto the first printed product (such as the first sheet of paper) and then reset it.

[0104] The first step distance S1 = b1 + H = 22 mm;

[0105] The second step distance S2 = a + H = 122 mm;

[0106] The third step distance S3 = k + H' = 700 + 3 = 703 mm;

[0107] The number of steps N(S1) = P1 ÷ S1 = 85 ÷ 22 = 3.86. Rounding down, let N(S1) = 3 times, that is, set the first step distance to be 3 steps evenly within the spacing P1, so that the hot stamping pattern of the hot stamping film in segment P1 is printed.

[0108] Then, small jumps can be performed, N(S2) = P2 ÷ (S2 + N(S1) × S1) + N(S1) × S1 = 2.09. Rounding down, this means two small jumps can be performed. After three even steps of the first step distance, another small jump (a combination of one second step distance and three first step distances) is performed twice. That is, first perform three even steps, then perform one small jump with the second step distance, and repeat twice. Figure 6 As shown, the distance of each small jump is the second step distance, filling the large gap to the maximum.

[0109] Finally, take a third large jump step to complete the entire jump step cycle.

[0110] The final hot stamping film will be applied in a cyclical manner according to the following formula:

[0111] 3×S1+2(S2+3×S1])+S3=1145mm

[0112] In an optional embodiment, after step S20 and before step S30, the hot stamping film usage control method of the present invention further includes:

[0113] S21. Simulate hot stamping based on the optimal number of steps and jump distance, and perform pattern overlap detection and record the empty parts;

[0114] S22. When the hot stamping pattern is found to overlap, adjust the optimal number of steps and / or the jump distance before simulating hot stamping again.

[0115] In other words, when hot stamping patterns overlap, the number of steps can be reduced, the step distance can be increased, or both can be reduced and increased to avoid overlapping. This saves hot stamping film material while ensuring the yield of hot stamping, allowing users to make quick adjustments to ensure the accuracy and clarity of the hot stamping pattern.

[0116] In step S21, based on the obtained hot stamping pattern parameters and the actual process flow, the hot stamping operation of the hot stamping machine is simulated. The simulation will display the specific position of the pattern on the hot stamping film, allowing users to intuitively check whether there are overlapping or empty parts.

[0117] Furthermore, step S21 also includes: assessing the secondary utilization potential of the hot stamping film based on the empty portion. That is, when the empty portion is greater than the set value, the empty portion can be adapted to be utilized by modifying the step distance, jump distance, etc. After adjusting the optimal number of steps and the optimal jump distance, hot stamping needs to be simulated again and the pattern overlap detection and empty portion recording are performed again until the simulated hot stamping pattern has no overlap and a reasonable empty portion is found.

[0118] In the absence of overlap, this invention automatically records and archives data on the empty areas around the pattern. This archiving of data helps staff assess the potential for secondary use of the material. Operators can then use these records to determine whether these empty areas can be better utilized during the production process, thereby maximizing the utilization rate of the hot stamping film.

[0119] This invention significantly reduces waste by calculating the utilization rate of hot stamping film. For example, if a strip of electroplated aluminum foil is 100 meters long and the width of the hot stamping pattern is 0.1 meters, with a total of 800 patterns printed, the utilization rate of the hot stamping film using this invention is 80%, thereby improving the efficiency of hot stamping film use, reducing waste, and ensuring the quality and accuracy of the printing and hot stamping process. This will also enable printing companies to more easily manage and control the amount of hot stamping film (such as electroplated aluminum foil) used, thus improving work efficiency.

[0120] Furthermore, the hot stamping film usage control method of the present invention also includes displaying the simulation results and recorded spare data in an intuitive way, which can be used for subsequent analysis to help operators make more optimized decisions and improve material utilization and production efficiency.

[0121] This invention provides operators with real-time simulation of the hot stamping process and offers data support to help printing companies optimize the layout of hot stamping patterns while minimizing material waste. This intelligent simulation will greatly simplify the process, improve production efficiency, and provide more possibilities for secondary utilization.

[0122] This invention can also control the hot stamping operation of the hot stamping machine through simulation results. During the hot stamping trial run, the machine operator can flexibly adjust the position of the electroplated aluminum and the printed material based on experience and actual conditions to ensure the best hot stamping effect.

[0123] This invention not only achieves precise control of the hot stamping process by monitoring the amount of hot stamping film used, but also provides detailed data on the amount of electroplated aluminum used, so as to better manage waste and support procurement decisions.

[0124] In step S30, monitoring the actual usage of hot stamping film also includes recording and classifying the usage. In real-time applications, three main types of electroplated aluminum usage are generally recorded: First, the usage during machine setup, which reflects the amount of electroplated aluminum lost due to adjusting machine parameters. Second, the actual printing usage, calculated based on the number of printed products. Third, the total usage.

[0125] Furthermore, after step S20 and before step S30, after obtaining the step distance, number of steps, and jump distance for each of the above situations, the corresponding calculation formulas are stored. The total amount of electroplated aluminum can then be calculated based on the quantity of printed materials and the type of hot stamping pattern. The total amount of aluminum is then submitted to the ERP (Enterprise Resource Planning) system to generate a purchase order to guide the purchasing department in purchasing consumables.

[0126] This application calculates and records the total usage of hot stamping film and feeds this total back to the Enterprise Resource Planning (ERP) system, providing real-time data support for adjusting procurement quantities. In addition, it can compare this usage with the theoretical usage (i.e., the usage calculated in step S20). Operators can set thresholds based on experience to determine if the difference between actual and theoretical usage is within a reasonable range. If the threshold is exceeded, the system will issue an alarm, prompting the process engineer and machine operator to investigate the problem. Specifically, when the hot stamping film utilization rate is lower than the preset threshold, an alarm message is output, prompting the process engineer and machine operator to investigate the problem, or adjusting the optimal number of steps and the optimal jump distance to further improve the film utilization rate.

[0127] This invention enables precise control of the hot stamping process and real-time monitoring of the amount of electroplated aluminum used, providing printing companies with a more intelligent and efficient production management method. Simultaneously, the output of alarm feedback information helps to provide early warning of potential problems, ensuring the stability and controllability of the production process, maximizing the utilization rate of electroplated aluminum, reducing waste, and ensuring the quality and accuracy of the printing and hot stamping process.

[0128] Based on the above-described method for controlling the amount of hot stamping film used, this invention also provides a control system for the amount of hot stamping film used. Please refer to [link / reference needed]. Figure 7 It includes:

[0129] Pattern acquisition module 1 is used to acquire hot stamping pattern parameters;

[0130] The usage calculation module 2 is used to calculate the optimal number of steps and the optimal step distance of the hot stamping film and the amount of hot stamping film used based on the hot stamping pattern parameters.

[0131] Hot stamping control module 3 is used to monitor the actual amount of hot stamping film used in real time during hot stamping and to calculate the utilization rate of hot stamping film based on the monitoring results.

[0132] Please refer to the embodiments corresponding to the above control methods for details.

[0133] In summary, this invention has an automatic hot stamping pattern parameter recognition function, which can intelligently extract key parameters of the hot stamping pattern from the imported file, including size, shape, spacing, etc., and flexibly select the best hot stamping scheme based on the recognized parameters, thereby optimizing the utilization rate of electroplated aluminum and improving the hot stamping quality.

[0134] Furthermore, by simulating the actual hot stamping process, operators can intuitively view the layout of the hot stamping pattern on the material, check for overlaps, and record any empty areas to support subsequent reuse.

[0135] Furthermore, this application supports procurement decisions and problem investigation by monitoring the actual usage of hot stamping film in real time and recording the usage of machine adjustments and actual printing.

[0136] In summary, this invention establishes a highly efficient hot stamping process control system by interconnecting various steps, including identifying hot stamping pattern parameters, calculating the number of steps and jump distances of the hot stamping film, simulating hot stamping based on settings, and actual machine control. It also provides timely feedback on total usage to the ERP system, offering accurate data support for procurement. Furthermore, it enables printing companies to manage the entire process from hot stamping pattern design to actual production, improving production efficiency and quality while minimizing waste of electroplated aluminum, thus saving costs for enterprises.

[0137] The contents already described herein in this specification and accompanying drawings include examples of methods and systems for controlling the amount of hot stamping film used.
