Technical Field

[0001] The present invention relates to the technical field of prefabricated inks, and in particular to an intelligent prefabricated ink method, device, computer equipment and storage medium. Background Art

[0002] At present, as the printing industry continues to increase its requirements for printing quality and efficiency, the adjustment of ink ratio and amount has become increasingly important in the textbook printing process. In order to ensure color accuracy and reduce resource waste, traditional ink mixing methods usually rely on fixed ratios and simple physical property models, such as ink absorption or paper type. However, these methods have certain limitations when faced with different textbook types, paper types, and dynamically changing environmental conditions during the printing process.

[0003] Most existing ink adjustment technologies cannot accurately adjust for different textbook contents and printing requirements, and fail to fully consider the impact of real-time feedback information and environmental changes during the printing process on ink performance. Traditional methods often result in problems such as ink waste, color deviation or color unevenness, which in turn affects printing effects and production efficiency.

[0004] Regarding the above-mentioned related technologies, there are the following defects: the existing technology fails to provide a dynamic ink adjustment mechanism based on real-time feedback information, environmental conditions and teaching material types, resulting in the inability to accurately match ink usage and color requirements, thereby affecting printing quality. Summary of the invention

[0005] In order to improve printing quality, the present application provides an intelligent pre-printed ink method, apparatus, computer equipment and storage medium.

[0006] The above-mentioned invention objective of the present application is achieved through the following technical solutions: A method for intelligently preparing ink, the method comprising: Obtain the type information of the textbook to be printed, and map the textbook type information with the corresponding ink color requirements through a preset color mapping algorithm to generate preliminary ink color requirement information; Acquire the paper type information to be printed, calculate the ink usage required for the paper type information during the printing process according to the paper property analysis algorithm, and obtain preliminary ink usage information; During the printing process, real-time feedback information of the printing device is obtained in real time, and according to the real-time feedback information, the preliminary ink color requirement information and the preliminary ink usage information are optimized by a dynamic ink adjustment algorithm to obtain optimized ink color requirement information and optimized ink usage information; According to the optimized ink color requirement information and the optimized ink usage information, combined with the real-time printing environment information, ink template information is obtained, and the ink template information includes the final ink color requirement information and the final ink usage information.

[0007] By adopting the above technical solution, through the combination of color mapping algorithm and textbook type information, it is possible to ensure that the printed ink color accurately matches the requirements of the textbook and meet the special color requirements of different textbook contents, thereby greatly improving the printing quality. Secondly, through the combination of paper property analysis algorithm and real-time feedback information, the ink usage can be accurately calculated to avoid ink waste and optimize the ink distribution ratio, thereby achieving a more economical and efficient printing process. In addition, the dynamic ink adjustment algorithm automatically optimizes the ink color requirements and usage during the entire printing process, reducing manual intervention, improving production efficiency, and being able to cope with different environmental conditions, such as temperature and humidity, to maintain the viscosity and fluidity of the ink, thereby ensuring printing quality.

[0008] In a preferred example, the present application can be further configured as follows: the obtaining of the type information of the teaching material to be printed, mapping the teaching material type information with the corresponding ink color requirement through a preset color mapping algorithm, and generating preliminary ink color requirement information, including: Acquire the color requirement characteristics in the teaching material type information, and map the color requirement characteristics with the color values ​​in the ink color database through the preset color mapping algorithm to obtain an ink color combination that matches the teaching material content; According to the ink color combination, combined with the color characteristic parameters in the ink color database, the ink component ratio is calculated to generate the preliminary ink color requirement information.

[0009] By adopting the above technical solution, firstly, the color requirement characteristics in the textbook type information are accurately matched with the color values ​​in the ink color database through the color mapping algorithm to ensure that the ink color fully meets the requirements of the textbook content. This process avoids the common color distortion problem in the traditional printing process, and can provide a more accurate color reproduction effect, thereby improving the visual effect of the textbook. Secondly, combined with the color characteristic parameters in the ink color database, the preliminary ink color requirement information is generated by calculating the ink component ratio, which not only effectively avoids the problem of excessive use of ink, but also ensures the stability and consistency of the color, so that each printed output can achieve the expected color effect. In this way, the color difference problem in the printing process is effectively controlled, and the printing accuracy and quality are significantly improved.

[0010] In a preferred example, the present application can be further configured as follows: the color requirement feature in the teaching material type information is obtained, and the color requirement feature is mapped with the color value in the ink color database through the preset color mapping algorithm to obtain an ink color combination matching the teaching material content, including: The color requirement characteristics are expressed by the following formula: C 需求 ={H 需求 , S 需求 , L 需求 , ΔH 需求 , ΔS 需求}, wherein the H 需求 For hue, the S 需求 For saturation, the L 需求 For brightness, the ΔS 需求 is the chromaticity change parameter, the ΔH 需求 is the hue shift, the C 需求 is the color requirement feature; The color requirement feature is converted into standard color space information through the preset color mapping algorithm. The process of color space conversion is: 需求标准 =f 转换 (The C 需求 ), wherein the C 需求标准 is the standard color space information, the f 转换 A conversion function representing the conversion of colors from the original space to the color space; According to the standard color space information of the color requirement feature, the color difference between the color requirement feature and each color value in the ink color database is calculated, and the calculation formula of the color difference is as follows: Among them, the H 需求标准 is the hue of the color requirement feature in the standard color space, and the S 需求标准 is the saturation of the color requirement feature in the standard color space, and the L 需求标准 is the brightness of the color requirement feature in the standard color space, and the w H , the w S , the w L It is the weight coefficient of hue, saturation and brightness, which is used to adjust the emphasis on different color characteristics when calculating color difference; The ink color combination matching the color requirement characteristics is selected by the following formula: C 匹配油墨 = argminΔE i 油墨 , the C 匹配油墨is the matching ink color combination, argmin means selecting the ink color value with the smallest color difference among all ink color values, and by selecting the matching ink color combination, the ink color combination matching the teaching material type information is formed.

[0011] By adopting the above technical solution, the color requirement characteristics (such as hue, saturation, brightness, etc.) in the textbook type information are converted into standard color space information through the color mapping algorithm, making the expression of color requirements more standardized and unified. This process avoids color deviations caused by different color spaces and ensures that the color requirements of the textbook can be accurately understood and implemented. Then, based on the color difference calculation between the color requirement characteristics and each color value in the ink color database, the accuracy of color matching is further refined. By adjusting the calculation of hue, saturation and brightness through the weight coefficient, the influence of different color characteristics on the final color difference can be flexibly adjusted, so that the deviation between the printed ink color and the color requirements of the textbook content is minimized, thereby achieving the best color reproduction effect. Finally, by selecting the ink color combination with the smallest color difference, the scheme can accurately match the most suitable ink formula to ensure that the ink color is highly consistent with the textbook type information during the printing process, which not only improves the color reproduction, but also enhances the consistency and stability of the printing effect.

[0012] In a preferred example, the present application can be further configured as follows: the paper type information to be printed is obtained, and the ink usage required for the paper type information in the printing process is calculated according to the paper characteristic analysis algorithm to obtain preliminary ink usage information, including: Acquire paper physical property information from the paper type information, and calculate the ink distribution ratio in each printing area by using the paper property analysis algorithm according to the paper physical property information and the ink property information; According to the allocation ratio, the required ink usage is calculated and determined to obtain the preliminary ink usage information.

[0013] By adopting the above technical solution, according to the physical properties in the paper type information (such as ink absorption rate, smoothness, etc.), combined with the ink characteristic information, the paper characteristic analysis algorithm is used to calculate the ink distribution ratio in each printing area. The paper characteristic analysis algorithm automatically adjusts the ink distribution plan according to the different characteristics of the paper and the physical characteristics of the ink to ensure that the ink can be evenly distributed during the printing process to avoid excessive or insufficient ink use. Secondly, based on the calculated ink distribution ratio, the total amount of ink required is further determined. This step ensures the accurate delivery of ink and makes dynamic adjustments based on the needs of the actual printing area, ensuring that the amount of ink used meets the color requirements and can effectively reduce ink waste.

[0014] In a preferred example, the present application may be further configured as follows: the paper physical property information is obtained from the paper type information, and the distribution ratio of ink in each printing area is calculated by the paper property analysis algorithm according to the paper physical property information and in combination with the ink property information, including: The paper property analysis algorithm calculates the distribution ratio of the ink in each printing area based on the following formula: Among them, the R i represents the ink distribution ratio of the i-th printing area, the P 纸质 is the paper physical property information, the T 油墨 is the ink characteristic information, A i is the area influence factor of the printing area, It is the sum of the various printing areas.

[0015] By adopting the above technical solution, the amount of ink required for each printing area is automatically calculated by considering the physical properties of the paper such as ink absorption rate, smoothness, surface roughness, etc., combined with the viscosity, coverage and other characteristics of the ink, combined with the area influencing factor of the printing area. In this way, the ink can be reasonably allocated according to the demand of each area, thereby avoiding the use of too much or too little ink and improving the printing effect.

[0016] In a preferred example, the present application can be further configured as follows: in the printing process, real-time feedback information of the printing device is obtained in real time, and according to the real-time feedback information, the preliminary ink color requirement information and the preliminary ink usage information are optimized by a dynamic ink adjustment algorithm to obtain optimized ink color requirement information and optimized ink usage information, including: Based on the ink state parameters in the real-time feedback information, the preliminary ink color requirement information is automatically adjusted through a dynamic ink adjustment algorithm to obtain optimized ink color requirement information; Ink distribution feedback information is obtained from the real-time feedback information, and based on a dynamic ink adjustment algorithm, the ink distribution ratio is dynamically adjusted in combination with the preliminary ink usage information and the ink distribution feedback information to obtain optimized ink usage information.

[0017] By adopting the above technical solution, the dynamic ink adjustment algorithm can automatically optimize the preliminary ink color requirement information in combination with the ink state parameters in the real-time feedback information to ensure that the ink color in the printing process achieves the expected effect. In addition, based on the ink distribution feedback information obtained in the real-time feedback information, the algorithm can dynamically adjust the ink distribution ratio in combination with the preliminary ink usage information to adapt to the actual changes in the printing process.

[0018] In a preferred example, the present application may be further configured as follows: in the printing process, real-time printing environment information is obtained, and based on the real-time printing environment information, the optimized ink color requirement information and the optimized ink usage information are adjusted by the dynamic ink adjustment algorithm to obtain ink template information, wherein the ink template information includes the final ink color requirement information and the final ink usage information, including: By combining the dynamic ink adjustment algorithm with the real-time printing environment information, the color parameter information in the optimized ink color requirement information is adjusted to obtain the final ink color requirement information; By using the dynamic ink adjustment algorithm and combining the influence of the real-time printing environment information on the viscosity and fluidity of the ink, the distribution ratio of the ink in each printing area is adjusted to obtain the final ink usage information.

[0019] By adopting the above technical solution, the color parameters (such as hue, saturation, brightness, etc.) in the optimized ink color requirement information are finely adjusted through the dynamic ink adjustment algorithm combined with real-time printing environment information to ensure color consistency under different environmental conditions (such as temperature, humidity, etc.) and avoid the potential impact of environmental factors on color. Secondly, real-time printing environment information (such as temperature and humidity) will affect the viscosity and fluidity of the ink. Based on this information, the dynamic ink adjustment algorithm automatically adjusts the distribution ratio of ink in each printing area to ensure that the ink is evenly distributed during the printing process, avoid excessive or insufficient ink use, and thus improve printing quality.

[0020] The second object of the invention is achieved by the following technical solutions: An intelligent pre-printed ink device, the intelligent pre-printed ink device comprising: The textbook type color mapping module is used to obtain the textbook type information required for printing, and map the textbook type information with the corresponding ink color requirements through a preset color mapping algorithm to generate preliminary ink color requirement information; A paper type ink usage calculation module is used to obtain the paper type information required for printing, calculate the ink usage required for the paper type information during the printing process according to the paper characteristic analysis algorithm, and obtain preliminary ink usage information; A dynamic ink adjustment optimization module is used to obtain real-time feedback information of the printing equipment in real time during the printing process, and optimize the preliminary ink color requirement information and the preliminary ink usage information through a dynamic ink adjustment algorithm according to the real-time feedback information to obtain optimized ink color requirement information and optimized ink usage information; The ink template generation module is used to obtain ink template information according to the optimized ink color requirement information and the optimized ink usage information in combination with real-time printing environment information, wherein the ink template information includes final ink color requirement information and final ink usage information.

[0021] By adopting the above technical solution, through the combination of color mapping algorithm and textbook type information, it is possible to ensure that the printed ink color accurately matches the requirements of the textbook and meet the special color requirements of different textbook contents, thereby greatly improving the printing quality. Secondly, through the combination of paper property analysis algorithm and real-time feedback information, the ink usage can be accurately calculated to avoid ink waste and optimize the ink distribution ratio, thereby achieving a more economical and efficient printing process. In addition, the dynamic ink adjustment algorithm automatically optimizes the ink color requirements and usage during the entire printing process, reducing manual intervention, improving production efficiency, and being able to cope with different environmental conditions, such as temperature and humidity, to maintain the viscosity and fluidity of the ink, thereby ensuring printing quality.

[0023] The fourth objective of the present application is achieved through the following technical solutions: A computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the above-mentioned intelligent pre-printed ink method are implemented.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1.

DETAILED DESCRIPTION

[0026] The present application is further described in detail below in conjunction with the accompanying drawings.

[0027] In one embodiment, if Figure 1 As shown, the present application discloses a method for intelligent prefabricated ink, which specifically includes the following steps: S10: Obtain the type information of the teaching material to be printed, and map the teaching material type information with the corresponding ink color requirement through a preset color mapping algorithm to generate preliminary ink color requirement information.

[0028] Specifically, the content features of the textbooks are first extracted from the type of textbooks to be printed, especially the color requirements, which include color requirement features such as hue, saturation, brightness, etc., and the color requirements of graphics, pictures or texts that may be contained in different types of textbooks are considered. Through the preset color mapping algorithm, these color requirement features are mapped with the color values ​​in the ink color database to find the ink color combination that best matches the textbook content, and finally generate preliminary ink color requirement information.

[0029] S20: Acquire the paper type information required for printing, calculate the ink usage required for the paper type information during the printing process according to the paper characteristic analysis algorithm, and obtain preliminary ink usage information.

[0030] Specifically, first obtain the information on the type of paper to be printed, mainly including the physical properties of the paper, such as the thickness, ink absorbency, smoothness, surface roughness, etc. These properties directly affect the distribution and adsorption of ink on the paper surface. By combining the ink characteristic information, such as the viscosity and coverage of the ink, the paper characteristic analysis algorithm is used to calculate and deduce the ink demand for each type of paper during the printing process. The algorithm calculates the ink distribution ratio of different papers in each printing area based on the paper properties and ink properties, and finally obtains preliminary ink usage information. Here, it is necessary to comprehensively consider factors such as the ink absorption capacity, surface state, and ink adhesion of different paper types to ensure accurate control of ink usage.

[0031] S30: During the printing process, real-time feedback information of the printing equipment is obtained in real time, and preliminary ink color requirement information and preliminary ink usage information are optimized through a dynamic ink adjustment algorithm according to the real-time feedback information to obtain optimized ink color requirement information and optimized ink usage information.

[0032] Specifically, during the printing process, feedback information from the printing equipment is obtained in real time, mainly including the ink status (such as ink concentration, viscosity, color consistency, etc.) and the working status of the equipment (such as printing speed, pressure, etc.). Based on these feedback data, a dynamic ink adjustment algorithm is used to optimize the preliminary ink color demand information and preliminary ink usage information in real time. The algorithm will automatically adjust the color ratio and usage of the ink according to the actual performance of the equipment to ensure the color accuracy and rationality of the ink usage during the printing process. For example, when the equipment feedback shows color deviation, the dynamic algorithm will automatically adjust the ink ratio according to the size of the deviation to ensure that the final printing effect meets expectations.

[0033] S40: During the printing process, real-time printing environment information is obtained. Based on the real-time printing environment information, the optimized ink color requirement information and the optimized ink usage information are adjusted by a dynamic ink adjustment algorithm to obtain ink template information. The ink template information includes the final ink color requirement information and the final ink usage information.

[0034] Specifically, after obtaining the optimized ink color requirement information and ink usage information, further combine the real-time printing environment information, such as temperature, humidity and other environmental status information, to make final adjustments. The fluidity and viscosity of the ink will change under different environmental conditions, so the color parameters and usage of the ink need to be adjusted according to the environmental information. For example, in a high temperature environment, the viscosity of the ink may decrease, resulting in insufficient color saturation. At this time, the ink ratio needs to be adjusted to adapt to the temperature change. On this basis, the final ink template information is generated, which contains the final ink color requirement information and the final ink usage information, providing accurate ink formulas for printing equipment. The ink template information can be used to guide the preparation and distribution of inks during the printing process, thereby ensuring the stability and consistency of the entire printing process.

[0035] In one embodiment, if Figure 2 As shown, in step S10, the type information of the textbook to be printed is obtained, and the textbook type information is mapped with the corresponding ink color requirement through a preset color mapping algorithm to generate preliminary ink color requirement information, including: S101: Acquire color requirement features in the teaching material type information, and map the color requirement features with color values ​​in the ink color database through a preset color mapping algorithm to obtain an ink color combination that matches the teaching material content.

[0036] Specifically, color requirement features are extracted from the textbook type information. These features include but are not limited to the color requirements of the pictures, charts, titles, backgrounds, etc. in the textbooks. These color requirements may be expressed as parameters such as hue, saturation, and brightness. After analyzing the textbook type information and identifying the color characteristics, these features are input into the preset color mapping algorithm. The mapping algorithm matches the color values ​​in the ink color database according to the color requirements of the textbooks to ensure that the selected ink color can accurately reflect the visual requirements of the textbooks.

[0037] S102: Calculate the ink component ratio based on the ink color combination and the color characteristic parameters in the ink color database to generate preliminary ink color requirement information.

[0038] Specifically, after obtaining the ink color combination, the color characteristic parameters contained in the combination are further analyzed. These color characteristic parameters usually include the concentration, transparency, drying time, coverage, etc. of each ink. Combined with the ink component parameters in the ink color database, the proportion of each color ink component is calculated through a preset algorithm. For example, if there is a high demand for red in the ink color combination, the algorithm will calculate the required amount of red ink based on the red component ratio, combined with the physical properties of the ink used and the printing requirements, and adjust the proportions of other colors to achieve the desired color balance.

[0039] In one embodiment, if Figure 3 As shown, in step S101, the color requirement characteristics in the teaching material type information are obtained, and the color requirement characteristics are mapped with the color values ​​in the ink color database through a preset color mapping algorithm to obtain an ink color combination that matches the teaching material content, including: S1011: The color requirement characteristics are expressed by the following formula: C 需求 ={H 需求 , S 需求 , L 需求 , ΔH 需求 , ΔS 需求}, where H 需求 is hue, S 需求 is saturation, L 需求 is the brightness, ΔS 需求 is the chromaticity change parameter, ΔH 需求 is the hue shift, C 需求 Required characteristics for color.

[0040] Specifically, hue (H 需求 ) indicates the type of color, usually expressed as an angle between 0 and 360 degrees, and saturation (S 需求 ) represents the purity or grayscale component of the color, ranging from 0 to 100%. The larger the value, the purer the color. Brightness (L需求 ) indicates the lightness or darkness of the color, usually a value from 0 to 100%, with 0 representing black and 100 representing white. In order to more accurately capture the color requirements of the teaching material content, ΔS 需求 and ΔH 需求 They represent the chromaticity change parameter and hue shift, which can describe the subtle changes in color and the shift of hue. 需求 Usually used to adjust the change in saturation, ΔH 需求 It is used to adjust the hue offset to ensure the accuracy of the matching textbook content. 需求 Represents the comprehensive result of the entire color demand characteristics, which can be combined with H 需求 , S 需求 , L 需求 and ΔS 需求 , the influence of ΔH demand is given, and a specific color demand value is given to guide the selection and adjustment of ink color.

[0041] S1012: Convert the color requirement characteristics into standard color space information through a preset color mapping algorithm. The process of color space conversion is: 需求标准 =f 转换 (The C 需求 ), where C 需求标准 is the standard color space information, f 转换 A conversion function that represents the conversion of colors from the original space to the color space.

[0042] Specifically, the color requirement features need to be mapped to the standard color space through a preset color mapping algorithm. The color space conversion process can be achieved through a color conversion function f 转换 This function is used to convert the original color requirement characteristics into values ​​in the target standard color space. Standard color spaces usually include common color modes such as RGB, CMYK, and Lab. The color space corresponding to each mode has different characteristics. Choosing a suitable color space can ensure that the final ink color is accurate. When converting, the color space conversion function f 转换 The color gamut difference between the original color characteristics and the standard color space and the weight coefficient of each color channel will be taken into account to make appropriate weight adjustments. For example, when converting HSL (hue, saturation, brightness) to RGB (red, green, blue) space, the color mapping algorithm will adjust the proportion of RGB color channels according to the hue angle, and adjust the color intensity of each channel based on the saturation and brightness information to ensure that the converted color can accurately represent the original color requirements. The converted standard color space information is C 需求标准 , representing the precise ink color combination required for the teaching material.

[0043] S1013: Calculate the color difference between the color requirement feature and each color value in the ink color database according to the standard color space information of the color requirement feature. The color difference calculation formula is as follows: Among them, H 需求标准 is the hue of the color requirement feature in the standard color space, S 需求标准 is the saturation of the color requirement feature in the standard color space, L 需求标准 is the brightness of the color requirement feature in the standard color space, w H , w S , w L It is the weight coefficient of hue, saturation and brightness, which is used to adjust the emphasis on different color characteristics when calculating color difference.

[0044] Specifically, based on the standard color space information, the color difference between the color requirement feature and each color value in the ink color database needs to be calculated first. The calculation of color difference is based on hue (H 需求标准 ), Saturation (S 需求标准 ), brightness (L 需求标准 ) and consider their relative importance in color difference calculation by weighting. The color difference calculation formula will adopt the CIEDE2000 standard color difference model, where w H 、w S , w L is the weight coefficient assigned to hue, saturation and brightness to adjust the accuracy and sensitivity of color difference. When calculating, first extract the hue, saturation and brightness parameters of each color value, and calculate the difference between these parameters and the corresponding values ​​in the standard color space required by the target color. Then, according to the weight coefficient in the formula, the difference between hue, saturation and brightness is integrated to obtain a comprehensive color difference value. The setting of weight coefficient is usually optimized according to the visual perception characteristics of color. Hue difference may have a greater impact on the perception of the human eye, so the corresponding weight w H may be set larger, and the effect of brightness differences is small, w L The weight can be lower. For example, when calculating the color difference between a certain ink color and the color requirement characteristics of the textbook, if the color requirement of the textbook is biased towards blue (H requirement is 180°), and the hue of the ink color is 170°, the calculation of the color difference will increase the impact of the hue difference, while considering the changes in saturation and brightness. Ultimately, the calculated color difference value will serve as the basis for evaluating the matching degree of the ink color with the color required by the textbook, helping to further determine the selection and adjustment of the required ink.

[0045] S1014: Select an ink color combination that matches the color requirement characteristics by the following formula: C 匹配油墨 = argminΔEi 油墨 , C 匹配油墨 For the matching ink color combination, argmin means selecting the ink color value with the smallest color difference among all ink color values. By selecting the matching ink color combination, an ink color combination matching the teaching material type information is formed.

[0046] Specifically, according to the color difference calculation result, the ink color combination matching the color requirement characteristics is selected by minimizing the color difference formula. Specifically, argmin in the formula means selecting the ink color value with the smallest color difference in the ink color database. By calculating the color difference of all possible ink colors, comparing the difference between the color difference of each ink color and the color requirement characteristics, the ink color combination with the smallest color difference is finally selected as the ink color combination matching the teaching material type information. For example, assuming that the color requirement characteristic of the teaching material is a specific blue tone, after the standard color space value is converted, the color requirement of the target hue of 180°, saturation of 75%, and brightness of 55% is obtained. If there are multiple candidate ink colors in the ink color database, for each candidate ink color, the color difference between the target color requirement is first calculated. Through calculation, the color difference value of each ink color can be obtained. Finally, the ink color value with the smallest color difference is selected as the matching result.

[0047] In one embodiment, if Figure 4 As shown, in step S20, the paper type information required for printing is obtained, and the ink usage required for the paper type information during the printing process is calculated according to the paper characteristic analysis algorithm to obtain preliminary ink usage information, including: S201: Acquire paper physical property information from paper type information, and calculate the ink distribution ratio in each printing area through a paper property analysis algorithm based on the paper physical property information and ink property information.

[0048] Specifically, first, the relevant paper physical property information is extracted from the paper type information, including ink absorption rate, surface smoothness, surface roughness, porosity, etc. These paper properties directly affect the diffusion and adsorption capacity of ink on the paper surface. Then, these paper physical property information is combined with the ink characteristic information (such as ink viscosity, coverage, drying time, etc.), and a comprehensive analysis is performed using the paper characteristic analysis algorithm to calculate the ink distribution ratio of each area during the printing process. The algorithm is adjusted based on the characteristics of different areas of the paper. For example, the edge area may have a larger surface roughness and stronger ink absorption, so more ink needs to be distributed, while the center area may have a smoother surface and lower ink absorption, so less ink is required. Specifically, the algorithm will optimize the ink distribution method according to the physical properties of different areas of the paper and the properties of the ink. For example, for paper with a higher ink absorption rate, the algorithm will ensure a uniform ink layer by increasing the ink distribution ratio of the edge area, while on smooth paper, the algorithm may reduce the amount of ink in this area to avoid uneven coating caused by excessive ink. The calculation of the ink distribution ratio will be optimized according to the distribution characteristics of the paper, such as texture, porosity, surface density, etc., so as to achieve the best ink distribution.

[0049] S202: Calculate and determine the required ink usage according to the allocation ratio to obtain preliminary ink usage information.

[0050] Specifically, according to the ink distribution ratio obtained by the paper characteristics analysis algorithm, combined with the area of ​​each printing area and the coverage of the ink, the required ink amount for each area is calculated. First, according to the area of ​​each area, the ink distribution ratio of the corresponding area is multiplied to obtain the preliminary ink amount for each area. This process needs to consider the viscosity, coverage and other characteristics of the ink to determine the amount of ink required per unit area. By combining these calculation results, the actual ink amount of each area is obtained, and the ink amount of all areas is further summarized. For example, for an area with a large surface roughness, the ink absorption is strong. The algorithm will calculate that the area requires more ink according to the distribution ratio of the area, while for a smooth area, due to poor ink absorption, the required amount of ink will be relatively reduced. The calculation of ink usage not only depends on the physical properties of the paper, but also needs to consider the performance of the ink under different conditions. For example, in a high humidity or high temperature environment, the ink may have different expansion characteristics. Therefore, the algorithm will adjust these parameters in time to ensure the accuracy of the ink usage. Finally, by comprehensively considering the distribution ratio and ink characteristics of each area, the total amount of ink required for the overall printing is calculated to obtain preliminary ink usage information.

[0051] Furthermore, the required ink dosage is calculated by the following formula: Among them, M totalIndicates the total ink usage, X i is the area of ​​the ith printing area (unit: square millimeters or square centimeters), R i is the ink distribution ratio of the i-th printing area (unit: proportional coefficient, the value range is usually 0 to 1), V i is the viscosity characteristic or coverage coefficient of the ink in the i-th printing area (this coefficient is used to indicate the fluidity or adhesion of the ink in this area), C i It is the paper ink absorption coefficient of the i-th printing area (the coefficient calculated based on the surface roughness, water absorption and other properties of the paper, in milliliters per square meter).

[0052] In one embodiment, if Figure 5 As shown, in step S201, the paper physical property information is obtained from the paper type information, and the distribution ratio of ink in each printing area is calculated by a paper property analysis algorithm according to the paper physical property information and the ink property information, including: S2011: The paper characteristics analysis algorithm calculates the ink distribution ratio in each printing area based on the following formula: Among them, R i represents the ink distribution ratio of the i-th printing area, P 纸质 is the physical property information of the paper, T 油墨 is the ink characteristic information, A i is the area influence factor of the printing area, It is the sum of all printing areas.

[0053] Specifically, in this formula, R i represents the ink distribution ratio of the i-th printing area, according to the paper property information P 纸质 , Ink characteristic information T 油墨 And the area influence factor A of the printing area i First, P 纸质 It includes many physical parameters of paper, such as ink absorption rate, smoothness, surface roughness, etc. These paper properties will affect the absorption degree and coating uniformity of ink. The higher the ink absorption rate of paper, the more ink will be needed to maintain the color saturation, and the surface roughness will affect the spreading effect of ink on the paper. The rough paper surface may cause uneven ink diffusion and affect the final printing quality. Smoothness affects the fluidity and uniformity of ink distribution on the paper. The ink distribution on the paper with higher smoothness is more uniform, which reduces the color difference. 油墨It covers the viscosity, coverage and other characteristics of the ink, which directly affect the printing effect of the ink. The viscosity of the ink determines the fluidity on the paper surface. Ink with too high viscosity may cause uneven printing. Coverage affects the uniformity of the ink when covering the paper surface. Ink with good coverage can better adhere to the paper surface, reducing color difference and ink waste. Next, A i is the area influencing factor of each printing area, which takes into account the area differences of different printing areas. For printing areas with larger areas, the algorithm will give a higher ink distribution ratio, while for areas with smaller areas, the ink distribution ratio will be correspondingly lower, ensuring that the ink distribution during the printing process is more reasonable and avoids waste. By combining these factors together, the algorithm calculates the R of each printing area. i The ink distribution ratio ensures that the ink distribution between different areas meets the printing requirements.

[0054] In one embodiment, if Figure 6 As shown, in step S30, that is, during the printing process, real-time feedback information of the printing equipment is obtained in real time, and according to the real-time feedback information, the preliminary ink color requirement information and the preliminary ink usage information are optimized through a dynamic ink adjustment algorithm to obtain optimized ink color requirement information and optimized ink usage information, including: S301: Based on the ink state parameters in the real-time feedback information, the preliminary ink color requirement information is automatically adjusted through a dynamic ink adjustment algorithm to obtain optimized ink color requirement information.

[0055] Specifically, the dynamic ink adjustment algorithm obtains the ink state parameters in the real-time feedback, including ink concentration, drying time, viscosity, temperature, etc., and then compares these parameters with the preset standard values. When it is detected that a certain ink state parameter deviates from the standard value, the algorithm will automatically take corresponding measures to adjust it. For example, if the ink concentration in the real-time feedback is too low, the algorithm will automatically increase the ink concentration or adjust the proportion of each component in the ink formula, such as increasing the solid particles in the ink and reducing the proportion of solvents to restore the ink concentration. If the feedback shows that the ink drying time is too long, the algorithm will adjust the drying process according to the printing speed and the characteristics of the ink, and optimize the ink drying time by adjusting the composition of the ink or the operating speed of the printing equipment, thereby improving production efficiency. In addition, the algorithm will make adjustments based on the changes in the viscosity of the ink. When the viscosity is too high, the solvent will be added or the operating mode of the printing equipment will be adjusted to reduce the viscosity of the ink to ensure that the ink can evenly cover the printing surface and avoid excessive ink viscosity, which affects the printing quality.

[0056] S302: Obtain ink distribution feedback information from the real-time feedback information, and dynamically adjust the ink distribution ratio based on a dynamic ink adjustment algorithm in combination with the preliminary ink usage information and the ink distribution feedback information to obtain optimized ink usage information.

[0057] Specifically, the dynamic ink adjustment algorithm further adjusts the ink distribution ratio of each printing area according to the ink distribution in the real-time feedback information. If too much ink is distributed in a certain printing area, the feedback information may show that the color of the area is too dark and the printing effect is uneven. The algorithm will reduce the ink supply in the area and adjust the ink distribution ratio. On the contrary, if the ink distribution in a certain area is insufficient, resulting in unsaturated colors and poor printing effects, the algorithm will increase the ink supply in the area to ensure that the color of the area is more uniform and full. At the same time, the algorithm will also consider the different areas of the printing area and the characteristics of the paper, such as the ink absorption rate and surface smoothness of the paper, comprehensively calculate the ink demand for each area, and make dynamic adjustments. This means that for different paper types or printing areas, the ink distribution ratio and amount will be optimized in real time according to the feedback information to ensure that the printing effect of each area meets expectations and the ink utilization is more efficient.

[0058] In one embodiment, if Figure 7 As shown, in step S40, i.e., during the printing process, real-time printing environment information is obtained, and based on the real-time printing environment information, the optimized ink color requirement information and the optimized ink usage information are adjusted by a dynamic ink adjustment algorithm to obtain ink template information, and the ink template information includes the final ink color requirement information and the final ink usage information, including: S401: adjusting the color parameter information in the optimized ink color requirement information through a dynamic ink adjustment algorithm in combination with real-time printing environment information to obtain the final ink color requirement information.

[0059] Specifically, in the actual printing process, the color requirements of the ink not only depend on the composition and ratio of the ink, but also on environmental factors. For example, factors such as temperature, humidity, and air flow rate will affect the coating effect and color presentation of the ink. When the temperature is too high, the volatility of the ink increases, which may cause the color saturation to decrease. When the humidity is too low, the ink absorption of the paper weakens, which may cause the ink adhesion to decrease and the color vividness to decrease. Therefore, the dynamic ink adjustment algorithm first collects environmental data in real time and analyzes the potential impact of the ink color. Based on this analysis result, the dynamic ink adjustment algorithm automatically adjusts the color parameters of the ink, such as hue, saturation, brightness, etc., to ensure that the ink can still maintain the expected color effect under different environmental conditions. For example, when the temperature is high, the dynamic ink adjustment algorithm can reduce the volatile components and reduce the color change of the ink to avoid color deviation, while when the humidity is low, the dynamic ink adjustment algorithm may increase the saturation of the ink and improve the color vividness to ensure consistent printing effects.

[0060] S402: By using a dynamic ink adjustment algorithm and combining the influence of real-time printing environment information on the viscosity and fluidity of the ink, the distribution ratio of the ink in each printing area is adjusted to obtain the final ink usage information.

[0061] Specifically, during the printing process, the viscosity and fluidity of the ink have an important impact on the ink distribution ratio and printing quality. Environmental factors, especially temperature and humidity, usually have a significant effect on the fluidity and viscosity of the ink. High temperature usually reduces the viscosity of the ink, resulting in enhanced ink fluidity, which may lead to uneven distribution on the paper, excess ink or color distortion, while in a low temperature environment, the viscosity of the ink is high and the fluidity is poor, which may lead to uneven ink distribution and even blockage. In order to cope with this change, the dynamic ink adjustment algorithm adjusts the physical properties of the ink such as viscosity and fluidity according to real-time printing environment information (such as temperature, humidity, etc.), and then accurately adjusts the ink distribution ratio in each printing area. For example, in a high temperature environment, the algorithm will reduce the fluidity of the ink and increase the viscosity component, thereby reducing the distribution of excessive ink. In a low temperature environment, the algorithm will increase the fluidity of the ink and reduce the uneven coating caused by excessive viscosity. This adjustment ensures that the ink distribution ratio of each printing area can maintain the best effect under different environmental conditions, thereby ensuring the stability and high quality of the final printing result.
