[0004] However, in the prior art, the influence of the coordination of the printing equipment cannot be eliminated before the multi-color printing process is executed, and real-time printing color analysis cannot be performed, so that multi-color printing control cannot be performed. In addition, the printing quality cannot be tested, the printing cannot be adjusted in time, and the printing environment cannot be monitored, so that targeted printing adjustment cannot be performed.

[0005] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0006] The purpose of the present invention is to solve the above-mentioned problems and to propose an intelligent adjustment method and system for multi-color printing process based on artificial intelligence.

[0009] The printing equipment coordination analysis unit performs printing coordination analysis on the printing equipment, collects coordination conveying data and coordination printing data, and infers whether there is a deviation in the coordination of the printing equipment based on data comparison. If yes, the equipment is controlled, otherwise, the printing process continues;

[0010] The printing color analysis unit performs printing color analysis on the execution process of the multi-color printing process, sets the color filling object, collects the color embodiment data and the color control data, and infers whether the printing color is abnormal based on the data analysis.

The deviation value is marked as color embodiment data;

[0016] The color control data is the density speed ratio corresponding to the numerical deviation between the actual density ratio of the color filling object in the real-time color printing area of ​​the printed product and the set density ratio and the decreasing speed of the area ratio of the color printing area where the corresponding density ratio deviates.

[0017] As a preferred embodiment of the present invention, if the color representation data exceeds the color ratio deviation threshold, or the color control data exceeds the density speed ratio threshold, a process control adjustment signal is generated; if the color representation data does not exceed the color ratio deviation threshold, or the color control data exceeds the density speed ratio threshold, a process color qualified signal is generated.

[0018] As a preferred embodiment of the present invention, the quality control information and the occasional deviation information are respectively the continuous area of ​​the color depth fluctuation corresponding to the color printing area of ​​the real-time printed product when the paper type is different during the execution of the multi-color printing process, and the continuous frequency of color uniformity fluctuation at the same position in the color printing area of ​​non-same printed products during the execution of the multi-color printing process.

If yes, perform equipment control, otherwise, continue the printing process;

[0024] Printing color analysis: Perform printing color analysis on the multi-color printing process, set color filling objects, collect color performance data and color control data, and infer whether the printing color is abnormal based on data analysis.

If yes, then perform printing environment control, otherwise, continue to monitor the printing environment.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. In the present invention, a printing coordination analysis is performed on the printing equipment, and the printing equipment coordination analysis of the printing equipment is used to infer whether there is any printing equipment influence on the current printing process, so as to avoid deviations in the printing effect caused by inconsistent paper conveying speeds of the printing equipment, reduce the execution efficiency of the multi-color printing process, affect the stability of the printing execution, and thus fail to achieve the optimal display effect;

[0029] Perform printing color analysis on the multi-color printing process. Use printing color analysis to infer whether the real-time printing color of the multi-color printing process meets actual needs, so that color monitoring can be carried out in a timely manner to ensure the color filling efficiency of the printing area. Real-time color monitoring can ensure that the printing color meets the efficiency and avoid abnormal multi-color coordination, which will cause a decrease in printing quality.

[0030] 2. In the present invention, the printing quality of the multi-color printing process is detected in real time to infer whether the printing quality of the current multi-color printing process meets the requirements, so as to avoid the occurrence of printing efficiency impact under the premise that the printing color process parameters and the printing equipment are qualified, thereby affecting the execution efficiency of the multi-color printing process and reducing the printing quality of the printed product;

[0031] The printing environment monitoring is carried out on the multi-color printing process. Through the printing environment monitoring, it is inferred whether the current printing environment affects the printing quality of the multi-color printing process, so as to carry out targeted screening of the printing quality detection and control objects, to avoid the influence of the printing environment. Frequent adjustment of the process parameters of the multi-color printing process causes the printing quality of the process to be unable to be in the optimal display state, and cannot effectively overcome the influence of the printing environment, further reducing the printing quality.

[0034] Figure 2 Flow chart of the method of the present invention. DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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.

[0036] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] See also Figure 1 As shown, an artificial intelligence-based multi-color printing process intelligent adjustment system includes a printing intelligent management platform, and the printing intelligent management platform is communicatively connected with a printing equipment coordination analysis unit, a printing color analysis unit, a printing quality detection unit, and a printing environment monitoring unit;

[0038] The printing management intelligent platform generates a printing equipment coordination analysis signal and sends the printing equipment coordination analysis signal to the printing equipment coordination analysis unit. After receiving the printing equipment coordination analysis signal, the printing equipment coordination analysis unit performs printing coordination analysis on the printing equipment. Through the printing equipment coordination analysis of the printing equipment, it is inferred whether there is any printing equipment influence on the current printing process, so as to avoid deviations in printing effects caused by inconsistent paper conveying speeds of the printing equipment, reduce the execution efficiency of the multi-color printing process, affect the stability of printing execution, and fail to achieve the optimal display effect.

[0039] Obtain the color uniformity floating span of the conveyed printing paper corresponding to the floating stage of the conveying speed of the printing paper during the execution of the multi-color printing process, wherein the color uniformity is expressed as the degree of visual consistency of the color on the surface of the printed matter or in a specific printing area, such as the color hue, saturation and other parameters; and mark the color uniformity floating span of the conveyed printing paper corresponding to the floating stage of the conveying speed of the printing paper during the execution of the multi-color printing process as coordinated conveying data;

[0040] Acquire the horizontality deviation value of the color printing area boundary of the adjacent printing paper during the execution of the multi-color printing process, and mark the horizontality deviation value of the color printing area boundary of the adjacent printing paper during the execution of the multi-color printing process as matching printing data;

[0041] And the color uniformity floating span corresponding to the conveying printing paper in the floating stage of the printing paper conveying speed during the execution of the multi-color printing process, and the horizontality deviation value of the color printing area boundary corresponding to the adjacent printing paper during the execution of the multi-color printing process are compared with the uniformity floating span threshold and the horizontality deviation threshold respectively:

[0042] If the color uniformity floating span of the conveyed printing paper corresponding to the floating stage of the printing paper conveying speed during the execution of the multi-color printing process exceeds the uniformity floating span threshold, or the horizontality deviation value of the color printing area boundary corresponding to the adjacent printing paper during the execution of the multi-color printing process exceeds the horizontality deviation threshold, it is inferred that there is a deviation in the coordination of the printing equipment during the execution of the multi-color printing supply, and a coordination deviation signal is generated and sent to the printing intelligent management platform. After receiving the coordination deviation signal, the printing intelligent management platform performs operation detection on the printing equipment, and timely adjusts the paper speed according to the remaining ink volume and ink output speed of the real-time multi-color printing to avoid the paper speed not meeting the current printing and causing the printing quality to decline;

[0043] If the color uniformity floating span of the conveyed printing paper corresponding to the floating stage of the printing paper conveying speed during the execution of the multi-color printing process does not exceed the uniformity floating span threshold, and the horizontality deviation value of the color printing area boundary corresponding to the adjacent printing paper during the execution of the multi-color printing process does not exceed the horizontality deviation threshold, it is inferred that there is no deviation in the coordination of the printing equipment during the execution of the multi-color printing supply, and a qualified coordination signal is generated and sent to the printing intelligent management platform;

[0044] After receiving the qualified matching signal, the printing intelligent management platform generates a printing color analysis signal and sends the printing color analysis signal to the printing color analysis unit. After receiving the printing color analysis signal, the printing color analysis unit performs printing color analysis on the execution process of the multi-color printing process, and infers whether the real-time printing color of the multi-color printing process meets the actual demand through printing color analysis, so as to be able to conduct color monitoring in time and ensure the color filling efficiency of the printing area. Through real-time color monitoring, the printing color can be guaranteed to meet the efficiency and avoid abnormal multi-color matching, which will cause the decline of printing quality.

[0045] Mark the fill color of the color space. In the prior art, the color space includes cyan, magenta, yellow, and black. In actual printing, the subtractive color mixing principle of the pigment is used to perform real-time printing color control.

[0046] When the printing equipment is running properly, the color type of the color space is set according to the real-time multi-color requirements of the current printing product, and marked as a color filling object;

[0047] A color analysis is performed on the real-time printed product at the start of printing, and a color value corresponding to a color emission spectrum in a color printing area of ​​the printed product is collected by a spectrophotometer. A numerical deviation value corresponding to a color ratio of the real-time color area and a set color ratio of the color filling object is obtained according to the real-time color value and the supply distribution of the color filling object, and the numerical deviation value corresponding to the color ratio of the real-time color area and the set color ratio of the color filling object is marked as color embodiment data;

[0048] The density speed ratio corresponding to the decrease speed of the color printing area area ratio with deviation in the corresponding density ratio is obtained by a densitometer, and the numerical deviation value between the actual density ratio of the color filling object in the real-time color printing area of ​​the printed product and the set density ratio is marked as color control data;

[0049] And the color embodiment data and the color control data are compared with the color ratio deviation threshold and the density speed ratio threshold respectively:

[0050] If the color performance data exceeds the color ratio deviation threshold, or the color control data exceeds the density speed ratio threshold, it is inferred that the printing color analysis of the multi-color printing process is abnormal, and a process control adjustment signal is generated and sent to the printing intelligent management platform. After receiving the process control adjustment signal, the printing intelligent management platform sets the process parameters for the multi-color printing process of the printing equipment, that is, adjusts the supply of each type of corresponding real-time color filling objects;

[0051] If the color performance data does not exceed the color ratio deviation threshold, or the color control data exceeds the density speed ratio threshold, it is inferred that the printing color analysis of the multi-color printing process is normal, and a process color qualified signal is generated and sent to the printing intelligent management platform;

[0052] At the same time, a printing quality detection signal is generated and sent to a printing quality detection unit. After receiving the printing quality detection signal, the printing quality detection unit performs real-time detection on the printing quality of the multi-color printing process, and infers whether the printing quality of the current multi-color printing process meets the requirements, so as to avoid the printing efficiency being affected under the premise that the printing color process parameters and the printing equipment are qualified, so as to affect the execution efficiency of the multi-color printing process and reduce the printing quality of the printed product;

[0053] The continuous area of ​​the color depth corresponding to the color printing area of ​​the real-time printed product when the paper type is different during the execution of the multi-color printing process is obtained, and at the same time, the continuous frequency of the color uniformity fluctuation at the same position of the color printing area in non-identical printed products during the execution of the multi-color printing process is obtained, and the continuous area of ​​the color depth corresponding to the color printing area of ​​the real-time printed product when the paper type is different during the execution of the multi-color printing process and the continuous frequency of the color uniformity fluctuation at the same position of the color printing area in non-identical printed products during the execution of the multi-color printing process are marked as quality control information and deviation sporadic information, respectively, and are compared with the continuous area area threshold and the continuous frequency threshold respectively: the specifications of the printed products of the same batch are consistent, and the same position in the scheme is marked as the same position relative to the non-identical printed products;

[0054] If the continuous area of ​​color depth fluctuation corresponding to the color printing area of ​​the real-time printed product exceeds the continuous area threshold when the paper type is different during the execution of the multi-color printing process, or the continuous frequency of color uniformity fluctuation at the same position in the color printing area of ​​different printed products during the execution of the multi-color printing process exceeds the continuous frequency threshold, it is inferred that the printing quality detection during the execution of the multi-color printing process is abnormal, and a printing quality risk signal is generated and sent to the printing intelligent management platform. After receiving the printing quality risk signal, the printing intelligent management platform synchronously adjusts the color supply of the real-time printing color in the multi-color printing process according to the type change of the printed product to ensure the printing quality, and controls the occasional failure of the printing deviation. If it exceeds the set threshold, the execution component corresponding to the failure is regulated;

[0055] If the continuous area of ​​color depth fluctuation corresponding to the color printing area of ​​the real-time printed product does not exceed the continuous area threshold when the paper types are different during the execution of the multi-color printing process, and the continuous frequency of color uniformity fluctuation at the same position in the color printing area of ​​different printed products during the execution of the multi-color printing process does not exceed the continuous frequency threshold, it is inferred that the printing quality detection during the execution of the multi-color printing process is normal, and a printing quality stability signal is generated and sent to the printing intelligent management platform;

[0056] At the same time, the printing intelligent management platform generates a printing environment monitoring signal and sends the printing environment monitoring signal to the printing environment monitoring unit. After receiving the printing environment monitoring signal, the printing environment monitoring unit monitors the multi-color printing process. Through the printing environment monitoring, it is inferred whether the current printing environment affects the printing quality of the multi-color printing process, so as to carry out targeted screening of the printing quality detection and control objects, so as to avoid the printing environment affecting the process parameters of the multi-color printing process. Frequent adjustment causes the printing quality of the process to be unable to be in the optimal display state, and the printing environment cannot be effectively overcome, which further reduces the printing quality.

[0057] The speed-duration ratio of the pigment drying speed fluctuation span at different temperatures and the pigment supply control duration at the printing time at different temperatures during the execution of the multi-color printing process is obtained, and the real-time color ratio duration of the corresponding color printing area under different humidity environments during the execution of the multi-color printing process is obtained. The speed-duration ratio of the pigment drying speed fluctuation span at different temperatures and the pigment supply control duration at the printing time at different temperatures during the execution of the multi-color printing process, and the real-time color ratio duration of the corresponding color printing area under different humidity environments during the execution of the multi-color printing process are marked as temperature impact data and humidity impact data, respectively, and compared with the speed-duration ratio threshold and the duration threshold, respectively:

[0058] If the speed time ratio of the floating span of the pigment drying speed at different temperatures and the pigment supply control time at the printing time at different temperatures during the execution of the multi-color printing process exceeds the speed time ratio threshold, or the real-time color ratio duration of the corresponding color printing area under different humidity environments during the execution of the multi-color printing process exceeds the duration threshold, it is inferred that the printing environment monitoring of the multi-color printing process is abnormal, and a printing environment abnormality signal is generated and sent to the printing intelligent management platform. After receiving the printing environment abnormality signal, the printing intelligent management platform performs printing environment control on the multi-color printing process. If there is currently printing quality control, the printing quality control will not be performed temporarily, and the printing environment control will be given priority. If there is still an abnormality, the printing quality control will be performed;

[0059] If the speed-to-time ratio of the pigment drying speed fluctuation span at different temperatures and the pigment supply control time at the printing moment at different temperatures during the execution of the multi-color printing process does not exceed the speed-to-time ratio threshold, and the real-time color ratio duration of the corresponding color printing area under different humidity environments during the execution of the multi-color printing process does not exceed the duration threshold, it is inferred that the printing environment monitoring of the multi-color printing process is normal, a normal printing environment signal is generated, and the normal printing environment signal is sent to the printing intelligent management platform;

[0060] See also Figure 2 As shown, an intelligent adjustment method for multi-color printing process based on artificial intelligence, the specific steps of the intelligent adjustment method are as follows:

[0061] Printing equipment coordination analysis: Conduct printing coordination analysis on printing equipment, collect coordination transmission data and coordination printing data, and infer whether there is any deviation in the coordination of printing equipment based on data comparison. If yes, perform equipment control, otherwise, continue the printing process;

[0062] Printing color analysis: Perform printing color analysis on the multi-color printing process, set color filling objects, collect color performance data and color control data, and infer whether the printing color is abnormal based on data analysis. If yes, make process adjustments, otherwise, continue the printing process;
