[0052] The following will Figures 1 to 4 further describe the present application in detail.

[0053] To improve the printing effect, the present application provides a printing method, system, terminal, and storage medium.

[0054] The present application provides a printing system, as Figure 1 shown, a printing system includes: a storage module 401, an acquisition module 402, an image acquisition module 403, a processing module 404, and an adjustment module 405; the above modules all belong to the internal modules of the printing server, that is, the functions implemented by the above modules are all executed by the server as the main body, and are displayed and operated through the intelligent terminal and the display device.

[0055] The storage module 401 is used to store the printing model; the acquisition module 402 is used to acquire the printing content and the printing model; the image acquisition module 403 is used to acquire the image information of the printed matter; the processing module 404 is used to generate the electronic version of the printing content, analyze the chromaticity information of the electronic version, and call the corresponding printing program from the printing model according to the chromaticity information; it is also used to output the optimal ink output rate according to the electronic version, the image information, and the printing model; the adjustment module 405 is used to output an adjustment instruction according to the optimal ink output rate.

[0056] When printing, the printing content can be printed once first, the printing result can be analyzed by using this system, and then the optimal ink output rate can be calculated according to the analysis result, so as to improve the overall printing effect.

[0057] An embodiment of the present application provides a printing method, and the main process of the method is described as follows.

[0058] Referring to Figure 2 , a printing method includes the following steps:

[0059] S101: Acquire the electronic version of the printing content and the preset printing model.

[0060] Wherein the electronic version is a picture and contains multiple printing pages, and the printing model contains multiple printing programs, and the ink output rates in the multiple printing programs are different.

[0061] Specifically, convert the printing content into a picture.

[0062] Obtain the data of the relationship between chromaticity and ink output rate through big data, and establish a printing model; wherein the printing model includes the relationship between the ink consumption of different colors and chromaticity, and the relationship between the ink output rate of the printing press and the ink consumption, and divide into different printing programs according to these corresponding relationships.

[0063] S102: Identify the electronic version, and input the identification result into the printing model to call the corresponding printing program.

[0064] Specifically, identify the image information of the electronic version, analyze the chromaticity of the image information, and call the corresponding printing program from the printing model according to the identification result for printing.

[0065] S103: Collect the image information of the printed matter after drying, and perform chromaticity comparison between the printed matter and the printed page, and output the comparison result.

[0066] After different inks dry, there may be different chromaticity changes. Therefore, it is necessary to analyze the image information of the printed matter in regions.

[0067] Specifically, each page is divided into regions with the same area according to a preset quantity.

[0068] Compare the chromaticity of each of the regions with the chromaticity of the corresponding region of the printed content, and determine the difference between the chromaticity of each region and the chromaticity of the corresponding region of the printed content.

[0069] Compare the differences of each adjacent region, and merge the regions with differences in the same interval according to a preset difference interval to generate multiple region blocks; the division of the preset difference interval is based on the absolute value of the difference, and is divided into continuous equal-difference intervals according to the same unit span, and the interval with the smallest absolute value of the difference is the standard difference interval.

[0070] Calculate the average difference of each region block and output it.

[0071] By dividing the entire page into small regions, it is possible to reduce the number of colors in a region and reduce the situation where the chromaticity difference in each region is too large; then by calculating the difference of each region and merging the regions with differences in the same interval according to a preset difference interval to generate multiple region blocks and adjusting the large region blocks, it is possible to reduce the requirements for calculation and the number of parameters to be adjusted, and will not have an obvious impact on the overall adjustment effect.

[0072] S104: Based on the material usage rule, calculate the optimal ink output rate according to the comparison result.

[0073] Specifically, do not process the region blocks with the average difference within the standard difference interval.

[0074] When the average difference of the region block is not within the standard difference interval, calculate the ink change amount; the calculation of the ink change amount includes: obtaining the area of the region block, the total area of the printed page, and the total ink consumption of the printed page; calculate the ink change amount according to the area of the region block, the average difference, the total area of the printed page, and the total ink consumption.

[0075] Based on the ink change amount and the printing model, calculate the optimal ink output rate for each region block.

[0076] By not processing the region blocks with small chromaticity differences, that is, the average difference is within the absolute difference interval, it is possible to reduce the fine calculations required for adjustment, and for the region blocks with the average difference outside the absolute difference interval, calculate the optimal ink output rate again.

[0077] After calculating the optimal ink output rate, the printing model is further improved.

[0078] Establishing the printing model further includes: training and adjusting the printing model according to the optimal ink output rate obtained each time and the comparison result; after each printing by this method, recording the relationship between the obtained optimal ink output rate and chromaticity into the printing model, so that when the next printing is performed through the printing model, the printing effect of the printed matter is better.

[0079] In another embodiment:

[0080] Referring to Figure 3 , since the drying temperature also has a certain influence on the chromaticity of the ink, a printing method further includes a drying parameter adjustment method.

[0081] S201: Collect the humidity information of the printed matter and the humidity information of the printed matter after drying.

[0082] Specifically, by detecting the humidity of the printed matter and the printed matter after drying, the corresponding humidity information is collected.

[0083] S202: Based on the drying model, recalculate the optimal drying parameters according to the humidity information of the printed matter and the humidity information of the printed matter after drying.

[0084] Specifically, establishing the drying model includes:

[0085] Obtain the historical data of printing and the limited temperature for ink drying.

[0086] Based on the historical data, establish a drying relationship model between the drying duration, drying temperature, limited temperature for ink drying and the humidity change of the printed matter.
