In addition, spatial relationship terms such as "upper", "lower", "front", "back", "left" and "right" are used to facilitate the description to explain the positional relationship between two components.

Embodiment 1

[0019] like Figure 1 As shown, the present application provides a method for determining ink components, comprising the following steps: Step T110, collecting expected printing performance parameters and initial printing condition parameters of the batch to be printed; Ink is an important material in the printing industry. It prints patterns and texts on substrates through printing or spraying. The composition parameters of ink and printing condition parameters (substrate material, environmental factors (such as ambient temperature and humidity), printing parameters (such as printing speed, printing pressure, printing temperature), printing component compatibility parameters (such as scraper compatibility, ink roller compatibility, printhead compatibility), etc.) all have an important impact on the quality of printing.

[0020] The quality of each batch of printing will be reflected in printing performance parameters such as color parameters (color accuracy, color saturation, color consistency, etc.), clarity parameters (resolution, dot quality, overprint accuracy, etc.), ink layer parameters (ink layer uniformity, ink layer thickness, etc.), and surface quality parameters (gloss, flatness, wear resistance, etc.).

[0021] Therefore, in order to determine the ink composition that can achieve the expected printing quality, it is necessary to consider the printing condition parameters of the ink when it is used in printing and the expected printing performance parameters after printing with the ink. Therefore, when determining the ink composition for each printing batch, it is necessary to collect the initial printing condition parameters of the batch to be printed, and also collect the expected printing performance parameters of the batch to be printed. , in, is the first expected printing performance parameter of the first expected printing performance parameter, is a second expected printing performance parameter of the first expected printing performance parameter, is the first expected printing performance parameter of the second expected printing performance parameter, The second expected printing performance parameter is the second expected printing performance parameter.

[0022] Step T120, modifying the dynamic initial printing condition parameters and keeping the static initial printing condition parameters unchanged; During the printing process of each printing batch, as time goes by, some categories of printing condition parameters (for example, environmental factors (ambient temperature, ambient humidity)) will change, some categories of printing condition parameters (for example, printing parameters (printing speed, printing pressure, printing temperature, paper tension, oven temperature)) will be adjusted, while other categories of printing condition parameters (for example, substrate material, printing component compatibility parameters (scraper compatibility, ink roller compatibility, nozzle compatibility), etc.)) will not change. Therefore, in order to comprehensively consider whether the overall printing quality can be achieved by using the ink in the entire printing batch, it is necessary to consider the different changing patterns of different printing condition parameters.

[0023] Therefore, the present application classifies the collected initial printing condition parameters into multiple groups of initial dynamic printing condition parameters and multiple groups of initial static printing condition parameters. Specifically, the initial dynamic printing condition parameters are , in, is the first initial dynamic printing condition parameter in the first group of initial dynamic printing condition parameters, is the second initial printing condition parameter in the first group of initial dynamic printing condition parameters, is the first initial dynamic printing condition parameter in the second group of initial dynamic printing condition parameters, is the second initial printing condition parameter in the second group of initial dynamic printing condition parameters. For example: the initial printing speed of the TRESU printing equipment is 250-300 m / min, the initial drying temperature of the oven is 120°C, and the initial power of the UV lamp is 75KW. The initial static printing condition parameters are , in, is the first initial static printing condition parameter in the first group of initial static printing condition parameters, is the second initial static printing condition parameter in the first group of initial static printing condition parameters, is the first initial static printing condition parameter in the second group of initial static printing condition parameters, It is the second initial static printing condition parameter in the second group of initial static printing condition parameters.

[0024] According to each group of initial dynamic printing condition parameters, its type parameter is obtained, and then according to the type parameter, a dynamic adjustment model that adapts to the corresponding type parameter is selected from the preset dynamic adjustment model, and the selected dynamic adjustment model is applied to dynamically adjust the initial dynamic printing condition parameters of the corresponding group, so as to correct the initial dynamic printing condition parameters. For example: if a group of initial dynamic printing condition parameters is an initial environmental factor (ambient temperature, ambient humidity), then according to the type parameter of the initial environmental factor, a dynamic adjustment model that adapts to the environmental factor is selected from all preset dynamic adjustment models, so as to dynamically adjust the initial environmental factor through the dynamic adjustment model that adapts to the environmental factor.

[0025] Specifically, the dynamic adjustment model is as follows: ; According to the dynamic adjustment model, the adjustment values ​​of each set of initial dynamic printing condition parameters at different times are obtained; wherein, For the The first of the initial dynamic printing condition parameters Initial dynamic printing condition parameters; for the moment; For the A dynamic adjustment model corresponding to a set of initial dynamic printing condition parameters; For the The first of the initial dynamic printing condition parameters The initial dynamic printing condition parameters are The adjustment value of the moment.

[0026] For example, the dynamic adjustment model for adjusting the initial environmental factors is: ; in, The first factor in the initial environment initial environmental factors; For the The weight of the initial environmental factors; For the The adjustment value corresponding to the initial environmental factors; It is a positive number, with a value of 0.1; For the Initial environmental factors adjust the weight value; It is a dynamic adjustment model corresponding to environmental factors.

[0027] The dynamic adjustment model for adjusting the initial printing parameters is: ; in, is the initial printing parameter Initial printing parameters; is the first parameter in the initial printing The initial printing parameters are The adjustment value of the moment; For the The weight of the adjustment value at the moment; is the first parameter in the initial printing The initial printing parameters are The adjustment value of the moment; Dynamic adjustment model corresponding to printing parameters.

[0028] Step T130, inputting the static initial printing condition parameters, the corrected dynamic initial printing condition parameters and the expected printing performance parameters into the ink component determination model to predict the comprehensive evaluation value of the ink components; Construct an ink component determination model as follows: ; in, is the comprehensive evaluation value of ink components; For the The first of the expected printing performance parameters Expected printing performance parameters; For the The first of the expected printing performance parameters The weight value corresponding to each expected printing performance parameter; is the number of expected printing performance parameters in each expected printing performance parameter; For the The weight values ​​of the expected printing performance parameters; is the number of expected printing performance parameters; is the total weight value of the expected printing performance parameters; It is the comprehensive standard value of the expected printing performance parameter, the dynamic initial printing condition parameter and the static initial printing condition parameter; It is the comprehensive standard evaluation value of ink components; For the The first one in the initial static printing condition parameters of the group Initial static printing condition parameters; For the The first one in the initial static printing condition parameters of the group The weight values ​​corresponding to the initial static printing condition parameters; is the number of initial static printing condition parameters for each set of initial static printing condition parameters; For the The weight values ​​of the initial static printing condition parameters of the group; is the number of groups of initial static printing condition parameters; For the The first of the initial dynamic printing condition parameters The initial printing condition parameters are The adjustment value of the moment; The total time limit for printing a batch; For the The first of the initial dynamic printing condition parameters The weight value corresponding to the initial printing condition parameters; The number of initial dynamic printing condition parameters for each set of initial dynamic printing condition parameters; For the The weight values ​​of the initial dynamic printing condition parameters of the group; is the number of groups of initial dynamic printing condition parameters; It is the total weight value of static printing condition parameters and dynamic printing condition parameters.

[0029] After the ink component determination model is constructed, the ink component determination model needs to be trained. In order to train the ink component determination model, it is also necessary to collect the actual historical ink component comprehensive evaluation values ​​in the historical printing batches, as well as the historical static printing condition parameters, historical dynamic printing condition parameters and historical printing performance parameters generated during the printing process of the historical printing batches, and then train the ink component determination model based on the actual historical ink component comprehensive evaluation values, historical static printing condition parameters, historical dynamic printing condition parameters and historical printing performance parameters.

[0030] In order to ensure the accuracy of the trained ink component determination model, it is also necessary to define a loss function for the ink component determination model. The loss function is as follows: ; in, Determine the loss function of the model for the ink components; For the The comprehensive evaluation value of the actual historical ink components of the historical printing batch; For the The predicted historical ink component comprehensive evaluation value of the historical printing batch; is the number of historical printing batches.

[0031] By inputting the historical static printing condition parameters, historical dynamic printing condition parameters and historical printing performance parameters generated during the printing process of the historical printing batch into the trained ink component determination model, the predicted historical ink component comprehensive evaluation value of the historical printing batch can be obtained. Then, the value of the loss function of the ink component determination model can be calculated based on the actual historical ink component comprehensive evaluation value of the historical printing batch and the predicted historical ink component comprehensive evaluation value of the historical printing batch.

[0032] The obtained loss function value of the ink component determination model is compared with the preset loss value range. If the obtained loss function value of the ink component determination model exceeds the preset loss value range, the ink component determination model training fails and needs to be retrained; if the obtained loss function value of the ink component determination model does not exceed the preset loss value range, the ink component determination model training is successful, and the trained ink component determination model can be applied to the subsequent prediction of ink components.

[0033] In the present application, the historical data (actual historical ink component comprehensive evaluation values, historical static printing condition parameters, historical dynamic printing condition parameters and historical printing performance parameters) used in the process of training the ink component determination model and the historical data (actual historical ink component comprehensive evaluation values, historical static printing condition parameters, historical dynamic printing condition parameters and historical printing performance parameters) used in the process of determining the loss of the ink component determination model are different historical data.

[0034] When predicting the ink components, the static initial printing condition parameters, the corrected dynamic initial printing condition parameters and the expected printing performance parameters are input into the trained ink component determination model to predict the comprehensive evaluation value of the ink components of the printing batch.

[0035] Step T140, determining the ink components of the batch to be printed according to the predicted comprehensive evaluation value of the ink components; After predicting the comprehensive evaluation value of the ink component, the predicted comprehensive evaluation value of the ink component is compared with the preset standard comprehensive evaluation value of the ink component corresponding to each ink component, and the ink component corresponding to the standard comprehensive evaluation value of the ink component closest to the predicted comprehensive evaluation value of the ink component is used as the component of the ink used for the batch to be printed.

[0036] The above steps T110 , T120 , T130 and T140 are all executed by a computer.

[0037] Embodiment 2 like Figure 2 As shown, the present application provides a system 200 for determining ink components, including: a collection module 210 , a correction module 220 , a maintenance module 230 , a prediction module 240 , a determination module 250 and a model determination module 260 .

[0038] The acquisition module 210 acquires expected printing performance parameters and initial printing condition parameters of the batch to be printed.

[0039] Ink is an important material in the printing industry. It prints patterns and texts on substrates through printing or spraying. The composition parameters of ink and printing condition parameters (substrate material, environmental factors (such as ambient temperature and humidity), printing parameters (such as printing speed, printing pressure, printing temperature), printing component compatibility parameters (such as scraper compatibility, ink roller compatibility, printhead compatibility), etc.) all have an important impact on the quality of printing.

[0040] The quality of each batch of printing will be reflected in printing performance parameters such as color parameters (color accuracy, color saturation, color consistency, etc.), clarity parameters (resolution, dot quality, overprint accuracy, etc.), ink layer parameters (ink layer uniformity, ink layer thickness, etc.), and surface quality parameters (gloss, flatness, wear resistance, etc.).

[0041] Therefore, in order to determine the ink composition that can achieve the expected printing quality, it is necessary to consider the printing condition parameters of the ink when it is used in printing and the expected printing performance parameters after printing with the ink. Therefore, when determining the ink composition for each printing batch, the collection module 210 collects the initial printing condition parameters of the batch to be printed, and also collects the expected printing performance parameters of the batch to be printed. , in, is the first expected printing performance parameter of the first expected printing performance parameter, is a second expected printing performance parameter of the first expected printing performance parameter, is the first expected printing performance parameter of the second expected printing performance parameter, The second expected printing performance parameter is the second expected printing performance parameter.

[0042] The correction module 220 corrects the dynamic initial printing condition parameters, and the maintenance module 230 keeps the static initial printing condition parameters unchanged.

[0043] During the printing process of each printing batch, as time goes by, some categories of printing condition parameters (for example, environmental factors (ambient temperature, ambient humidity)) will change, some categories of printing condition parameters (for example, printing parameters (printing speed, printing pressure, printing temperature, paper tension, oven temperature)) will be adjusted, while other categories of printing condition parameters (for example, substrate material, printing component compatibility parameters (scraper compatibility, ink roller compatibility, nozzle compatibility), etc.)) will not change. Therefore, in order to comprehensively consider whether the overall printing quality can be achieved by using the ink in the entire printing batch, it is necessary to consider the different changing patterns of different printing condition parameters.

[0044] Therefore, in the present application, the acquisition module 210 classifies the acquired initial printing condition parameters into multiple groups of initial dynamic printing condition parameters and multiple groups of initial static printing condition parameters. Specifically, the initial dynamic printing condition parameters are , in, is the first initial dynamic printing condition parameter in the first group of initial dynamic printing condition parameters, is the second initial printing condition parameter in the first group of initial dynamic printing condition parameters, is the first initial dynamic printing condition parameter in the second group of initial dynamic printing condition parameters, is the second initial printing condition parameter in the second group of initial dynamic printing condition parameters. For example: the initial printing speed of the TRESU printing equipment is 250-300 m / min, the initial drying temperature of the oven is 120°C, and the initial power of the UV lamp is 75KW. The initial static printing condition parameters are , in, is the first initial static printing condition parameter in the first group of initial static printing condition parameters, is the second initial static printing condition parameter in the first group of initial static printing condition parameters, is the first initial static printing condition parameter in the second group of initial static printing condition parameters, It is the second initial static printing condition parameter in the second group of initial static printing condition parameters.

[0045] The correction module 220 obtains the type parameter of each group of initial dynamic printing condition parameters, and then selects a dynamic adjustment model that is adapted to the corresponding type parameter from the preset dynamic adjustment model according to the type parameter, and dynamically adjusts the initial dynamic printing condition parameters of the corresponding group using the selected dynamic adjustment model, thereby correcting the initial dynamic printing condition parameters. For example, if a group of initial dynamic printing condition parameters is an initial environmental factor (ambient temperature, ambient humidity), then a dynamic adjustment model that is adapted to the environmental factor will be selected from all preset dynamic adjustment models according to the type parameter of the initial environmental factor, thereby dynamically adjusting the initial environmental factor through the dynamic adjustment model that is adapted to the environmental factor.

[0046] Specifically, the dynamic adjustment model is as follows: ; The correction module 220 obtains the adjustment value of each set of initial dynamic printing condition parameters at different times according to the dynamic adjustment model; wherein, For the The first of the initial dynamic printing condition parameters Initial dynamic printing condition parameters; for the moment; For the A dynamic adjustment model corresponding to a set of initial dynamic printing condition parameters; For the The first of the initial dynamic printing condition parameters The initial dynamic printing condition parameters are The adjustment value of the moment.

[0047] For example, the dynamic adjustment model for adjusting the initial environmental factors is: ; in, The first factor in the initial environment initial environmental factors; For the The weight of the initial environmental factors; For the The adjustment value corresponding to the initial environmental factors; It is a positive number, with a value of 0.1; For the Initial environmental factors adjust the weight value; It is a dynamic adjustment model corresponding to environmental factors.

[0048] The dynamic adjustment model for adjusting the initial printing parameters is: ; in, is the initial printing parameter Initial printing parameters; is the first parameter in the initial printing The initial printing parameters are The adjustment value of the moment; For the The weight of the adjustment value at the moment; is the first parameter in the initial printing The initial printing parameters are The adjustment value of the moment; Dynamic adjustment model corresponding to printing parameters.

[0049] The prediction module 240 inputs the static initial printing condition parameters, the modified dynamic initial printing condition parameters and the expected printing performance parameters into the ink component determination model to predict the comprehensive evaluation value of the ink components.

[0050] The model determination module 260 constructs an ink component determination model, which is as follows: ; in, is the comprehensive evaluation value of ink components; For the The first of the expected printing performance parameters Expected printing performance parameters; For the The first of the expected printing performance parameters The weight value corresponding to each expected printing performance parameter; is the number of expected printing performance parameters in each expected printing performance parameter; For the The weight values ​​of the expected printing performance parameters; is the number of expected printing performance parameters; is the total weight value of the expected printing performance parameters; It is the comprehensive standard value of the expected printing performance parameter, the dynamic initial printing condition parameter and the static initial printing condition parameter; It is the comprehensive standard evaluation value of ink components; For the The first one in the initial static printing condition parameters of the group Initial static printing condition parameters; For the The first one in the initial static printing condition parameters of the group The weight values ​​corresponding to the initial static printing condition parameters; is the number of initial static printing condition parameters for each set of initial static printing condition parameters; For the The weight values ​​of the initial static printing condition parameters of the group; is the number of groups of initial static printing condition parameters; For the The first of the initial dynamic printing condition parameters The initial printing condition parameters are The adjustment value of the moment; The total time limit for printing a batch; For the The first of the initial dynamic printing condition parameters The weight value corresponding to the initial printing condition parameters; The number of initial dynamic printing condition parameters for each set of initial dynamic printing condition parameters; For the The weight values ​​of the initial dynamic printing condition parameters of the group; is the number of groups of initial dynamic printing condition parameters; It is the total weight value of static printing condition parameters and dynamic printing condition parameters.

[0051] After the ink component determination model is constructed, the ink component determination model needs to be trained. In order to train the ink component determination model, the acquisition module 210 needs to collect the actual historical ink component comprehensive evaluation value in the historical printing batch, as well as the historical static printing condition parameters, historical dynamic printing condition parameters and historical printing performance parameters generated during the printing process of the historical printing batch, and then the model determination module 260 trains the ink component determination model based on the actual historical ink component comprehensive evaluation value, historical static printing condition parameters, historical dynamic printing condition parameters and historical printing performance parameters.

[0052] In order to ensure the accuracy of the trained ink component determination model, the model determination module 260 is also required to define a loss function for the ink component determination model. The loss function is as follows: ; in, Determine the loss function of the model for the ink components; For the The comprehensive evaluation value of the actual historical ink components of the historical printing batch; For the The predicted historical ink component comprehensive evaluation value of the historical printing batch; is the number of historical printing batches.

[0053] The model determination module 260 inputs the historical static printing condition parameters, historical dynamic printing condition parameters and historical printing performance parameters generated during the printing process of the historical printing batch into the trained ink component determination model, and can obtain the predicted historical ink component comprehensive evaluation value of the historical printing batch. Then, the model determination module 260 can calculate the value of the loss function of the ink component determination model based on the actual historical ink component comprehensive evaluation value of the historical printing batch and the predicted historical ink component comprehensive evaluation value of the historical printing batch.

[0054] The model determination module 260 compares the obtained value of the loss function of the ink component determination model with the preset loss value range. If the obtained value of the loss function of the ink component determination model exceeds the preset loss value range, the ink component determination model training fails and needs to be retrained; if the obtained value of the loss function of the ink component determination model does not exceed the preset loss value range, the ink component determination model training is successful, and the trained ink component determination model can be applied to subsequent ink component predictions.

[0055] In the present application, the historical data (actual historical ink component comprehensive evaluation values, historical static printing condition parameters, historical dynamic printing condition parameters and historical printing performance parameters) used in the process of training the ink component determination model and the historical data (actual historical ink component comprehensive evaluation values, historical static printing condition parameters, historical dynamic printing condition parameters and historical printing performance parameters) used in the process of determining the loss of the ink component determination model are different historical data.

[0056] When predicting the ink components, the prediction module 240 inputs the static initial printing condition parameters, the corrected dynamic initial printing condition parameters and the expected printing performance parameters into the trained ink component determination model to predict the comprehensive evaluation value of the ink components of the printing batch.

[0057] The determination module 250 determines the ink components of the batch to be printed according to the predicted comprehensive evaluation values ​​of the ink components.

[0058] After predicting the comprehensive evaluation value of the ink component, the determination module 250 compares the predicted comprehensive evaluation value of the ink component with the preset standard comprehensive evaluation value of the ink component corresponding to each ink component, and uses the ink component corresponding to the standard comprehensive evaluation value of the ink component closest to the predicted comprehensive evaluation value of the ink component as the component of the ink used for the batch to be printed.

[0059] The above-mentioned acquisition module 210, correction module 220, retention module 230, prediction module 240, determination module 250 and model determination module 260 are all program segments executed by the CPU, or hardware units with data processing capabilities.

[0060] The present application determines the components of the ink to be used for the batch to be printed by considering the expected printing performance parameters, the static initial printing condition parameters, and the corrected dynamic initial printing condition parameters, so that the ink components can meet the ink requirements for printing on the TRESU equipment and the performance standards of the instant invoice product, thereby improving the printing performance.
