Step S600: Perform global optimization within the set of jet printing solutions to obtain the optimal jet printing scheme;

Further, step S600 of this application also includes:

Step S610: Randomly select one jet printing scheme from the plurality of jet printing scheme sets as the first jet printing scheme;

Step S620: Calculate the fitness of the first jet printing scheme according to the preset rules to obtain the first fitness;

Step S640: Calculate the fitness of the second jet printing scheme according to the preset rules to obtain the second fitness;

Step S650: Determine whether the second fitness is greater than the first fitness. If so, use the second jet printing scheme as the current optimization scheme. If not, use the second jet printing scheme according to probability. The solution is used as the current optimization solution, where the probability is calculated by the following formula:

Among them, r ₂ is the second fitness, r ₁ is the first fitness, and k is the optimization speed factor that decreases with the optimization process;

Step S660: When the current optimization solution does not change in the preset number of iterations, output the current optimization solution as the optimal jet printing solution.

Specifically, preset rules are used to calculate the fitness of the first jet printing scheme and the second jet printing scheme respectively, and the first fitness and the second fitness are obtained. Further, it is judged whether the second fitness is greater than the first fitness, and if the second fitness is greater than the first fitness, the second jet printing plan is used as the current optimization plan. If the second fitness is not greater than (that is, equal to or less than) the first fitness, use the probability calculation formula After calculation, the second jet printing scheme is used as the current optimization scheme. Furthermore, an iterative optimization with a preset number of iterations is performed on the current optimization plan.

For example, the preset number of iterations is 20 times. In 20 iterative optimizations, the current optimization plan has not changed, which indicates that it is difficult to find a new current optimization plan. The current optimization plan can be considered as the global optimal, that is, the current optimization plan is the optimal jet printing plan.

In the probability calculation formula Among them, k is the optimization speed factor that decreases with the optimization process. In the early stage of optimization with a preset number of iterations, if k is large, the first printing plan has a high probability not to be the final optimal printing plan, but may be a local optimum. In order to avoid the optimization process stagnating at the first At the first jet printing scheme, k is larger, so that P is larger, and the second, inferior jet printing scheme is accepted as the optimal jet printing scheme with a greater probability, and the probability is the same as the first fitness r ₁ and the second jet printing scheme. The difference between the two fitness r ₂ is related to improve the optimization speed and quickly iterate the optimization. In the later stage of optimization, the current optimization solution has a high probability of being the optimal printing solution. In order to improve the accuracy of optimization, k is smaller, so that P is smaller, and the inferior third solution is accepted with a smaller probability. The second jet printing scheme is the optimal jet printing scheme. Optionally, the reduction method of k can be exponential reduction or any reduction method in the prior art. Based on this, the technical effect of determining the optimal jet printing solution with high reliability and adaptability is achieved.

Further, step S620 of this application also includes:

Step S621: Calculate the printing quality information of each of the products under the jet printing scheme according to the plurality of required information sets;

Step S622: Calculate the printing efficiency information of each of the products under the jet printing scheme according to the plurality of required information sets;

Step S623: Perform a weighted sum of the printing quality information and the printing efficiency information to obtain fitness.

Specifically, when calculating the fitness of the first jet printing scheme according to the preset rules, based on the multiple required information sets that have been obtained, the information of multiple products that need to be jet printed corresponding to the first jet printing scheme are obtained. Printing quality information and printing efficiency information are weighted and summed to obtain the first fitness. Similarly, when calculating the fitness of the second jet printing scheme according to the preset rules, the printing quality of multiple products that need to be jet printed corresponding to the second jet printing scheme is obtained based on the multiple required information sets that have been obtained. information and printing efficiency information, and after weighting and summing them, the second fitness is obtained. It achieves the technical effect of obtaining first adaptation and second adaptation with high accuracy according to the preset rules, thereby improving the accuracy of the subsequent optimal jet printing solution.

Step S700: Use the optimal jet printing scheme to control the production of multiple products.

Specifically, actual inkjet printing production control of multiple products that require inkjet printing is carried out based on the obtained optimal inkjet printing plan. The technical effect of using the optimal jet printing solution to control the production of more precise and highly automated multi-product production line jet printing has been achieved.
