Description

Technical Field

[0001] This invention relates to the field of inkjet printing, and more particularly to a method, apparatus, equipment, and medium for determining a compensation scheme based on efficiency and quality. Background Technology

[0002] Inkjet printing refers to the process of spraying ink droplets onto a printing medium through nozzles on a printhead to obtain images or text. However, after a long period of operation, inkjet printer printheads are prone to abnormal nozzle conditions due to ink path contamination, ink sedimentation, dust, moisture, etc., such as clogging, oblique spraying, blurring, and insufficient ink volume. This can lead to problems such as streaks and blank areas in the printed image, seriously affecting product quality.

[0003] When printhead nozzles malfunction, existing technologies involve cleaning, ink pressing, and scraping to unclog the nozzles, or using compensation techniques to correct the malfunctioning nozzles. However, in practice, it has been found that even after cleaning or compensation, the print quality remains unimproved or only partially improved in some cases, ultimately requiring printhead replacement. Both printhead cleaning and compensation printing are time-consuming. Therefore, if cleaning and compensation fail to improve print quality when nozzles malfunction, it severely impacts printing efficiency and product delivery. Conversely, replacing the printhead directly while compensation significantly improves print quality increases printing costs considerably. Furthermore, analysis reveals that inappropriate compensation techniques can lead to no improvement or only a poorly improved print quality. Therefore, developing a solution that determines the handling strategy based on the condition of malfunctioning nozzles is urgently needed. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a method, apparatus, equipment and medium for determining a compensation scheme based on efficiency and quality.

[0064] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the invention.

[0065] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0066] Please see Figure 1 This invention provides a method for determining a compensation scheme based on efficiency and quality, the method comprising:

[0067] S1. Obtain all available compensation schemes for this abnormal nozzle;

[0068] S2. Calculate the corresponding printing efficiency and printing quality for each of the compensation schemes to be used;

[0069] S3. Determine the final actual compensation scheme to be used based on each of the stated printing efficiencies and each of the stated printing qualities.

[0070] Specifically, for a malfunctioning nozzle in a printing task, there are multiple compensation schemes to be used depending on the printing mode and printing parameters. Each compensation scheme has its corresponding printing efficiency and printing quality. By combining the calculated printing efficiency and printing quality, the actual compensation scheme to be used for the malfunctioning nozzle is determined. This ensures that the final production solves the nozzle malfunction problem and meets the requirements of quality and efficiency, avoiding the waste of resources caused by blind compensation.

[0071] In some embodiments, the printing mode includes two printing modes: interlaced printing and high-speed continuous printing; for details, please refer to [link to relevant documentation]. Figure 2 The interlaced printing is achieved by alternating reciprocating motion of the printhead along the X-axis and forward motion along the Y-axis of the printer, or by alternating forward motion of the printing medium along the Y-axis. During the reciprocating motion of the printhead along the X-axis, ink is ejected to print the image, and the forward motion of the printhead or printing medium along the Y-axis moves the printing position. Please refer to [link to relevant documentation]. Figure 3 The high-speed continuous printing is achieved by keeping the printhead stationary while the printing medium moves continuously at a certain speed along the Y-axis of the printer. During the continuous movement of the printing medium along the Y-axis, the printhead sprays ink to print the image.

[0072] Furthermore, in the interlaced printing mode, the compensation scheme to be used includes: a first step compensation scheme, a first feathering compensation scheme, and an ink dot compensation scheme.

[0073] The first step of the compensation scheme involves adjusting the forward distance of the printhead relative to the printing medium in the Y-axis direction each time, so that the normal nozzle moves to the position of the abnormal nozzle, thereby compensating for the abnormal nozzle. Please refer to [link to relevant documentation]. Figure 4In one implementation of the first-step compensation scheme, the printing coverage per unit area is 4 times in this compensation printing. The step distance is 1 / 4 of the printhead height, meaning the printhead moves forward a distance of 1 / 4 of the printhead height relative to the printing medium in the Y-axis direction each time. The printhead is then divided into four equal parts, J1, J2, J3, and J4, based on the distance the printhead moves relative to the medium in the Y-axis direction each time. There is an abnormal nozzle in part J4. The printing medium is divided into several regions, B1, B2, B3, B4, B5…, based on the distance the printhead moves relative to the medium in the Y-axis direction each time. At the start of printing, part J4 first enters region B1 for printing. Due to the abnormal nozzle in part J4… The nozzles in the J4 section are normal, so the white gaps in the printout will be compensated by using normal nozzles that are in the same position as the malfunctioning nozzles. Then, the printhead moves 1 / 4 of its height relative to the nozzle in the Y-axis direction, so the J4 section enters the B2 region, the J3 section enters the B1 region, and the J2 section enters the B1 region. At this time, the nozzles in the J2 section are normal, so the J2 section can also be compensated by using normal nozzles that are in the same position as the malfunctioning nozzles. This process is repeated. The above embodiments are merely one implementation of the step compensation scheme. When determining the final compensation scheme, different step distances will be calculated. For example, compensation schemes with step distances of 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.5, 2, and 3 times the base distance will be automatically calculated according to the following rules, or compensation schemes with step distances of 0.25, 0.5, and 0.75 times the base distance will be calculated. The base distance is the distance obtained based on printing requirements and printing parameters to meet printing needs. Figure 4 If the print coverage of a unit area is 4 times, then the step distance of 1 / 4 of the printhead height is the base distance. Furthermore, the above embodiments are compensation schemes with uniform step distances. Simultaneously, a compensation scheme with non-uniform step distances can be calculated by customizing the forward distance of the printhead relative to the printing medium in the Y-axis direction each time. Different step distances affect the probability of abnormal nozzle compensation, thus affecting the printing efficiency and quality of the compensation scheme. Therefore, it is necessary to calculate the printing efficiency and quality under various step distances to find a compensation scheme with relatively good efficiency and quality. The values ​​in the above embodiments are only for better explanation and illustration of the implementation of the scheme and are not the only limitation; specific values ​​are not limited.

[0074] The first feathering compensation scheme adds feathering technology to the original printing scheme, that is, some data that would originally be printed in one go is printed in two parts, thereby increasing the number of times certain areas are covered, and compensation can be performed on each coverage, thus increasing the probability of compensation; please refer to Figure 5 In one implementation of the first feathering compensation scheme, 100% feathering is used in this compensation printing, meaning all data that would normally be printed in one go is split into two parts. Originally, the printhead was divided into two equal parts, A1 and A2, based on the relative distance it moves along the Y-axis each time. There was an abnormal nozzle × in part A1. With staggered printing, the abnormal nozzle × could only be compensated once. However, with the addition of 100% feathering, the printhead is divided into four equal parts, L1, L2, L3, and L4, based on the relative distance it moves along the Y-axis each time. The abnormal nozzle × is located in part L4. The printing medium is divided into several regions, D1, D2, D3, etc., based on the relative distance the printhead moves along the Y-axis each time. At the start of printing, part L4 first enters region D1 for printing. Because part L4 contains an abnormal nozzle ×... The normal nozzle × will cause gaps in the printout. Then, the printhead moves 1 / 4 of its height relative to the abnormal nozzle in the Y-axis direction. At this time, the L4 part enters the D2 area and the L3 part enters the D1 area. At this time, the nozzles in the L3 part are normal. Therefore, the normal nozzles in the L3 part can be used to compensate for the gaps in the L4 part. Then, the printhead moves 1 / 4 of its height relative to the abnormal nozzle in the Y-axis direction again. At this time, the L4 part enters the D3 area, the L3 part enters the D2 area, and the L2 part enters the D1 area. At this time, the nozzles in the L2 part are normal. Therefore, the normal nozzles in the L2 part can be used to compensate for the gaps in the L4 part. This process is repeated. It can be seen that the abnormal nozzle × can compensate three times. Therefore, feathering can increase the probability of compensation, but it will also reduce the distance the printhead moves relative to the abnormal nozzle in the Y-axis direction each time, resulting in a decrease in printing efficiency. The above embodiments are merely one implementation of the first feathering compensation scheme. When determining the final compensation scheme, compensation schemes under different feathering amplitudes will be calculated. For example, compensation schemes with feathering amplitudes of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, and 90% will be automatically calculated according to the following rules, or compensation schemes with custom feathering amplitudes will be calculated. Different feathering amplitudes will affect the probability of abnormal nozzle compensation, thereby affecting the printing efficiency and printing quality of the compensation scheme. Therefore, it is necessary to calculate the printing efficiency and printing quality under multiple feathering amplitudes in order to find a compensation scheme with better efficiency and quality.

[0075] The ink droplet compensation scheme compensates for abnormal nozzle print data by changing the size of the ink droplets in the adjacent rows above and below the nozzle and in the current row, or adjacent columns above and below the nozzle and in the current column. In some embodiments, the ink droplet types include small, medium, and large droplets, where the volume of a small droplet is smaller than that of a medium droplet, and vice versa. During compensation, small droplets can be changed to medium or large droplets, and medium droplets can be changed to large droplets. This ink droplet compensation scheme does not affect the relative distance the printhead moves along the Y-axis each time; that is, it operates according to a base distance, and the printing efficiency remains constant. However, it can improve print quality within a certain range. Therefore, this compensation scheme can be chosen when the efficiency is fixed and the compensation quality is acceptable.

[0076] Furthermore, in the high-speed continuous printing mode, the compensation scheme to be used includes: a second step compensation scheme and an ink dot compensation scheme.

[0077] The second step compensation scheme compensates for abnormal nozzles by adjusting the step distance of the printing medium per unit time in the Y-axis direction of the printer; please refer to [link to relevant documentation]. Figure 6In one implementation of the second step compensation scheme, in this embodiment, without step compensation, the step distance of the printing medium in the Y-axis direction of the printer per unit time is V. The cyan ink nozzle C, magenta ink nozzle M, yellow ink nozzle Y, and black ink nozzle K print uniformly without overlap. At this time, there is an abnormal nozzle × in the cyan ink nozzle C. Because the non-overlapping printing of the ink nozzles causes white spots, to compensate for these white spots, the step distance of the printing medium in the Y-axis direction of the printer is adjusted to V / 2 per unit time. Because the step distance is halved, the yellow ink nozzle Y and the cyan ink nozzle C overlap printing, and the black ink nozzle K and the magenta ink nozzle M overlap printing. The nozzles in the yellow ink nozzle Y are all normal. Therefore, during overlapping printing, this can be used to compensate for the ink dots of the abnormal nozzle × in the cyan ink nozzle C. The above embodiment is only the second step. One approach to compensation schemes involves calculating compensation schemes at different step distances when determining the final compensation scheme. For example, compensation schemes can be automatically calculated using step distances of 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.5, 2, or 3 times the base distance, or using step distances of 0.25, 0.5, or 0.75 times the base distance, or using a custom step distance. The base distance is the step distance of the printing medium per unit time in the Y-axis direction of the printer when various ink color printheads are non-overlapping and printing uniformly. Different step distances affect the probability of abnormal nozzle compensation, thus affecting the printing efficiency and quality of the compensation scheme. Therefore, it is necessary to calculate the printing efficiency and quality under various step distances to find a compensation scheme with both good efficiency and quality.

[0078] The ink dot replenishment scheme in the high-speed continuous printing mode is the same as the ink dot replenishment scheme in the staggered printing mode, and will not be described again here.

[0079] Furthermore, please refer to Figure 7 The step of calculating the corresponding printing efficiency based on each of the compensation schemes to be used includes:

[0080] S211. Obtain the step distance corresponding to each of the compensation schemes to be used;

[0081] S212. Calculate the printing speed corresponding to each compensation scheme to be used based on each step distance and the printing parameters of the task to be printed;

[0082] S213. Determine the printing efficiency corresponding to each of the compensation schemes to be used based on each of the printing speeds.

[0083] Specifically, the printing parameters include: the size information of the image to be printed, the printing mode, the number of times the unit area is covered, and the operating speed of the inkjet device; the size information of the image to be printed includes the width in the X-axis direction and the length in the Y-axis direction, and the operating speed of the inkjet device includes the speed at which the printhead moves relative to the printing medium in the X-axis and Y-axis directions; in the staggered printing mode, the printing speed corresponding to the compensation scheme is calculated based on the step distance, the speed at which the printhead moves in the X-axis and Y-axis directions, and the width of the image to be printed in the X-axis direction, and then the printing speed is calculated based on the number of times the unit area is covered, the printing speed corresponding to the compensation scheme, and the length of the image to be printed in the Y-axis direction. The printing efficiency is calculated as follows: If a certain compensation scheme to be used adopts a uniform stepping method for printing, that is, the distance the printhead moves relative to the printing medium in the Y-axis direction is the same each time, the stepping distance is S1, the number of times the unit area is covered is N, the printing parameters of the printing task are the speed of the printhead relative to the printing medium in the X-axis direction is V1, the speed of the printhead relative to the printing medium in the Y-axis direction is V2, the width of the image to be printed in the X-axis direction is M1, and the length in the Y-axis direction is M2, then the printing speed corresponding to the compensation scheme to be used is: (S1V1+M1V2) / V2V1, and the printing efficiency is: (S1V1+M1V2)(M2+NS1-S1) / V2V1S1. In high-speed continuous printing mode, the speed of the printhead relative to the printing medium in the X-axis direction is 0. The printing speed is obtained based on the step distance and the speed of the printhead in the Y-axis direction. The printing efficiency is obtained based on the printing speed and the length of the image to be printed in the Y-axis direction. Generally, the step distance and the speed of the printhead in the Y-axis direction are equal and equal to the printing speed. For example, if the step distance of a certain compensation scheme to be used is S2 and the length of the image to be printed in the Y-axis direction is M3, then the printing efficiency is: M3 / S2.

[0084] Furthermore, please refer to Figure 8 The calculation of the corresponding print quality based on each of the compensation schemes to be used includes:

[0085] S221. Obtain the printing parameters for the task to be printed;

[0086] S222. Control the inkjet device with abnormal nozzles to print test images according to the printing parameters and each of the compensation schemes to be used;

[0087] S223. Scan and analyze the test image to obtain the compensation quality of each of the compensation schemes to be used.

[0088] Specifically, the printing parameters of the task to be printed are obtained. Based on the printing parameters, a portion of the image to be printed is extracted as a test image, or a new test image is designed. Then, according to the printing parameters, all compensation schemes to be used are applied to control the inkjet equipment with abnormal nozzles to print the test image once. After printing, an image acquisition device scans all the printed test images and analyzes them to obtain the compensation quality of each compensation scheme to be used. In some embodiments, the printing parameters include the number of print passes (the number of times a unit area of ​​image is scanned back and forth by the printhead), the required printing accuracy of the image, the number of nozzles in the inkjet equipment, and the nozzle arrangement. Using a portion of the image corresponding to the task to be printed as the test image makes the evaluation of compensation quality more accurate and closer to reality, but it may be less efficient. Using a redesigned image as the test image is more targeted and can quickly test the compensation quality, which is more efficient, but the accuracy needs to be considered. In some cases, the compensation quality is obtained by binarizing the effect image obtained by scanning the test image, and calculating the number of blank points in the image corresponding to the abnormal hole based on the binarized image, thus obtaining the compensation quality.

[0089] Furthermore, please refer to Figure 9 Step S3: Determining the final actual compensation scheme based on each of the printing efficiencies and each of the printing qualities includes:

[0090] S311. Obtain a first efficiency threshold and compare the first magnitude relationship between each printing efficiency and the first efficiency threshold;

[0091] S312. Based on the first size relationship, obtain all compensation schemes to be used whose printing efficiency is greater than or equal to the first efficiency threshold, and denot them as the first compensation scheme group.

[0092] S313. Obtain a first quality threshold and compare the second magnitude relationship between each of the printed qualities and the first quality threshold;

[0093] S314. Based on the second size relationship, obtain all compensation schemes to be used whose print quality is greater than or equal to the first quality threshold, and denot them as the second compensation scheme group.

[0094] S315. Based on the first compensation scheme group and the second compensation scheme group, obtain all the compensation schemes to be used that are simultaneously in the first compensation scheme group and the second compensation scheme group, and denot them as the third compensation scheme group.

[0095] S316. Determine the final actual compensation scheme to be used based on the print quality and print efficiency corresponding to each of the compensation schemes in the third compensation scheme group.

[0096] Specifically, in some embodiments, printing efficiency and printing quality have minimum limits based on production requirements and printing quality requirements, namely a first efficiency threshold and a first quality threshold. At this point, a group of compensation schemes that simultaneously meet both requirements can be selected, referred to as a third compensation scheme group. Then, the final compensation scheme to be used is determined from the third compensation scheme group. This method is highly efficient and simple to calculate. Specifically, the printing efficiency corresponding to each compensation scheme is compared with the first efficiency threshold, and all compensation schemes with printing efficiencies greater than or equal to the first efficiency threshold are selected, referred to as the first compensation scheme group. The printing quality corresponding to each compensation scheme is compared with the first quality threshold, and all compensation schemes with printing qualities greater than or equal to the first quality threshold are selected, referred to as the second compensation scheme group. At this point, most compensation schemes that do not meet the requirements have been filtered out. Then, based on the first and second compensation scheme groups, all compensation schemes that are simultaneously in both compensation scheme groups are calculated and referred to as the third compensation scheme group. Finally, the actual compensation scheme to be used is selected from the third compensation scheme group.

[0097] Furthermore, in this embodiment, the compensation scheme to be used corresponding to the print quality with the largest value in the third compensation scheme group is the actual compensation scheme. This can maximize the print quality while also meeting the production requirements in terms of printing efficiency.

[0098] Furthermore, in this embodiment, the compensation scheme to be used corresponding to the printing efficiency with the largest value in the third compensation scheme group is the actual compensation scheme. This can maximize production efficiency while ensuring that the printing quality meets the printing requirements.

[0099] Furthermore, please refer to Figure 10 In this embodiment, step S316: determining the final actual compensation scheme to be used based on the print quality and print efficiency corresponding to each of the compensation schemes in the third compensation scheme group includes:

[0100] S3161. Obtain the first sequence table of the printing efficiencies corresponding to the third compensation scheme group, arranged in order of size.

[0101] S3162. Obtain the second sequence table of the print quality corresponding to the third compensation scheme group, which is numbered in order of size.

[0102] S3163. Based on the first sequence table and the second sequence table, obtain the number values ​​of the printing efficiency and the printing quality, and the minimum compensation scheme to be used as the actual compensation scheme;

[0103] This method ensures that the final compensation plan can perfectly balance printing efficiency and printing quality, avoiding the problem of one of the indicators being relatively low due to using the maximum printing efficiency or the maximum printing quality.

[0104] Furthermore, please refer to Figure 11 Step S3: Determining the final actual compensation scheme based on each of the printing efficiencies and each of the printing qualities includes:

[0105] S321. Obtain a third sequence table of each printing efficiency numbered in ascending order;
