Abstract
Description
Technical Field
[0001] This invention relates to the field of inkjet printing technology, and in particular to an intelligent curing method, apparatus, device, and storage medium for inkjet printing. Background Technology
[0002] As the application fields of industrial inkjet printing continue to expand, the demand for customized images is increasing. Different images have different colors and densities. Since inkjet printing involves rapidly spraying ink onto a specified printing medium, when printing images with different color densities, it is essential to ensure that the ink can be quickly absorbed or fixed on the printing medium without spreading, in order to achieve the best image printing effect.
[0003] Currently, a common method is to quickly solidify the image (ink) onto the material using a heating / curing device, thereby enhancing the material's absorption of the ink. However, this approach still has some drawbacks. Because the curing power of the device is often fixed during image curing, this fixed power cannot adapt to images with varying ink concentrations. If the curing power is adjusted to suit images with higher ink concentrations, then images with lower ink concentrations may experience over-curing or overheating, leading to deformation or damage to the printing media. Conversely, images with higher ink concentrations may not be cured, causing the ink to spread across the material and reducing image quality. Summary of the Invention

[0054] 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.
[0055] 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.
[0056] Example 1
[0057] like Figure 1 As shown, after an inkjet printer prints an image, a curing device cures the image to prevent image diffusion during subsequent ink rewinding or undried ink adhering to the back of the printed medium when it is rolled up, thus affecting image quality. In existing technologies, the curing device has a fixed power throughout the image curing process. This results in poor curing in areas with high ink volume or density, while over-curing occurs in areas with low ink volume or density, leading to deformation or damage to the printed medium. Therefore, this invention provides an intelligent curing method for inkjet printing that intelligently adjusts the curing power based on the ink volume corresponding to the image, thereby avoiding under- or over-curing.
[0058] Please see Figure 2 This invention provides an inkjet printing smart curing method, which includes:
[0059] S1: Divide the image to be printed into several image units;
[0060] S2: Obtain the ink volume corresponding to each image unit, and record it as the first ink volume;
[0061] S3: Obtain the curing power corresponding to each image unit based on the first ink volume, and record it as the first curing power;
[0062] S4: Perform solidification processing on the corresponding image unit according to the first solidification power.
[0063] Specifically, due to the limited curing area in the curing device, it does not cure the entire printed image at once, but rather cures while printing, that is, curing only the printed portion of the image while the inkjet printer continues printing the remaining portions. Therefore, the image to be printed can be divided into several image units (regions), and the ink volume corresponding to each image unit is obtained, denoted as the first ink volume. Based on the first ink volume for each image unit, the curing power corresponding to each image unit is obtained, denoted as the first curing power. When the image unit is finished printing and moves past the curing device, the curing device adjusts its power to the curing power corresponding to that image unit, performing heat curing on that image unit. Before printing, a mapping relationship between ink volume and curing power can be established, for example, specifying a certain ink volume corresponding to a higher curing power. In one embodiment, the mapping relationship can be many-to-one, meaning that all ink volumes within a certain range correspond to a single curing power. For example, when the ink volume is greater than or equal to a and less than or equal to b, its corresponding curing power is m; when the ink volume is greater than b and less than or equal to c, its corresponding curing power is n. In another embodiment, the mapping relationship can be a one-to-one relationship, which can be discrete or continuous. For example, when the ink volume is 'a', the corresponding curing power is 'm'; when the ink volume is 'b', the corresponding curing power is 'n'; and when the ink volume is 'c', the corresponding curing power is 'k'. A continuous one-to-one mapping relationship is achieved by establishing a function of ink volume versus curing power. For example, y = ax, where y is the curing power, x is the ink volume, and a is a coefficient. Once the ink volume of the image unit is obtained, the curing power can be calculated using the above function. Therefore, based on the mapping relationship, the curing power corresponding to the image unit can be obtained by obtaining the ink volume of that image unit. After printing the image unit, the power of the curing device can be intelligently adjusted according to the ink volume of the image unit, achieving intelligent curing of the image and avoiding under- or over-curing, thus ensuring image quality.
[0064] The ink volume of an image unit can be obtained by calculating the print data obtained after RIP processing of the image to be printed. For example, the print data obtained after RIP processing can be divided into image units, and the ink volume of the image unit can be obtained according to the ink volume of each print data corresponding to that image unit. Alternatively, the ink volume corresponding to each image unit can be calculated and counted by using the printhead drive board during the printing process.
[0065] The image to be printed is divided into image units, which can be done according to the actual printing task. Taking repeating scanning inkjet printing as an example, such as... Figure 3 The diagram illustrates a 4-pass printing process (4 scans) of an image to be printed. In the first pass, the printhead moves along the main scanning direction, printing pixel ①. Then, the printhead moves a certain distance relative to the printing medium (either the printhead remains stationary while the printing medium moves along the secondary scanning direction, or vice versa), and then moves in the opposite direction along the main scanning direction, printing pixel ②. Next, the printhead moves a certain distance relative to the printing medium, then moves again along the main scanning direction and prints pixel ③. After moving a certain distance relative to the printing medium, it moves in the opposite direction again, printing pixel ④. After 4 passes, image area A is printed; after another 4 passes, image area B is printed, and this process is repeated until printing is complete. Therefore, the image to be printed can be divided into image units according to the size of image areas such as A and B. After printing one image unit in every 4 passes, when that image unit moves to the curing unit, the curing unit adjusts the curing power according to the ink volume of that image unit and performs heat curing.
[0066] In Single-Pass inkjet printing, the printing process involves a single paper feed and image formation, unlike reciprocating inkjet printing which requires multiple passes to complete a portion of the image. In this case, the image unit can be divided based on the maximum curing area of the curing unit in a single pass. The ink volume for each image unit is then determined from the image data. When the Single-Pass printer completes printing one image unit in a single pass and moves to the curing unit, the curing unit adjusts its curing power based on the ink volume corresponding to that image unit, thus achieving intelligent curing.
[0067] In practical printing applications, cyan, magenta, yellow, and black inks, i.e., CMYK four-color inks, are often used for color image printing. Different color inks have different leveling or curing times due to the different materials added. Therefore, these factors can be taken into account to further optimize the image printing effect while achieving intelligent curing.
[0068] In some embodiments, cyan ink, magenta ink, yellow ink, and black ink are used for printing. The step of obtaining the ink volume corresponding to each image unit, denoted as the first ink volume, includes:
[0069] The ink volume of cyan ink, magenta ink, yellow ink, and black ink corresponding to the printed image unit is obtained respectively, and the first ink volume is the sum of the ink volumes of cyan ink, magenta ink, yellow ink, and black ink;
[0070] The step of obtaining the curing power corresponding to each image unit based on the first ink volume, denoted as the first curing power, includes:
[0071] The leveling time of cyan ink, magenta ink, yellow ink, and black ink were obtained respectively;
[0072] The first curing power is obtained based on the leveling time and ink volume of the cyan ink, magenta ink, yellow ink, and black ink.
[0073] Specifically, after RIP processing of the image to be printed, the resulting print data is further divided into image units. Then, the print data for each image unit is further divided into four CMYK channels to obtain the print data corresponding to each color channel. The cyan channel is printed with cyan ink, the magenta channel with magenta ink, the yellow channel with yellow ink, and the black channel with black ink. Based on the print data for each channel, the ink volume for each color can be determined. Therefore, the print data for each image unit is actually a combination of the print data for each channel, and the sum of the ink volumes for each color is the first ink volume. In addition to obtaining the ink volume for each color channel, the leveling time for each color ink is also obtained. The leveling time affects the image printing quality, and the curing time can be adjusted based on the leveling time to achieve better printing results. Therefore, by combining the ink volume and leveling time for each color channel in the image unit, the curing power for that image unit is determined, thereby controlling the curing time. For example, a weight value is assigned to each color ink based on the ink volume and leveling time. The larger the ink volume or the longer the leveling time, the greater the weight, and vice versa. Finally, the final curing power corresponding to the image unit is obtained by multiplying the weight of each color ink by a preset curing power, thereby further optimizing the image printing effect while achieving intelligent curing.
[0074] In some embodiments, after the image unit is printed, it is not cured immediately. Instead, it needs to travel for a certain period of time with the printing medium to reach the curing device before curing. To ensure that the curing device adjusts its curing power to match the ink volume of the image unit when it arrives, the following steps are required before curing:
[0075] S10: Obtain the time when each printed image unit arrives at the curing device, and record it as the image arrival time;
[0076] S11: Switch the first curing power of the curing device according to the arrival time of the image.
[0077] Furthermore, the time it takes for each printed image unit to reach the curing device includes:
[0078] S101: Record the printing completion time of each image unit;
[0079] S102: Obtain the movement time corresponding to each image unit based on the moving speed and moving distance of the printing medium;
[0080] S103: Obtain the image arrival time based on the printing completion time and the movement time.
[0081] After printing an image unit, the printing completion time of that image unit is recorded. The time it takes for the image unit to reach the curing device from the point of printing completion needs to be determined based on the data and distance the image moves during this process. The moving speed of the image unit is actually the moving speed of the printing medium, which can be determined from the stepper speed of the motor and is constant. The moving distance depends on the specific position of the curing device in the printing equipment, and can therefore be measured based on actual conditions. Based on the moving distance and moving speed of the image unit, the time interval from the point of printing completion to the point of reaching the curing device can be determined and recorded as the moving time. Therefore, by recording the printing completion time of the image unit and adding the moving time, the arrival time of the image to the curing device can be obtained. When the current time is the arrival time corresponding to the image unit, the curing power of the curing device is adjusted to the power corresponding to the image unit, and the curing process of the image unit is performed.
[0082] In some embodiments, the image unit can be pre-cured / heat-treated before reaching the curing device. Therefore, after the image unit is printed, it is not cured immediately, but needs to be moved to the curing device along with the printing medium before curing. If the ink is not fixed or cured, it may affect the final image printing quality. In this case, pre-curing treatment can be performed before printing the image unit or immediately after printing, and final curing treatment can be performed after reaching the curing device.
[0083] In one embodiment, when an image unit requires several scans to print, pre-curing can be performed on the image portion after each pass (single scan print) is completed. The image scanned in each pass, or the image printed in each scan, is denoted as a single scan image. Similarly, based on the ink volume corresponding to a single scan image, the pre-curing power corresponding to that single scan image is obtained and denoted as the second curing power. After each pass is completed, the pre-curing power corresponding to that pass image (single scan image) is used to perform pre-curing processing on that pass's image (single scan image). This pre-curing can be performed using an accelerated curing device installed on the printing platform. The specific steps are as follows:
[0084] S20: Obtain the ink volume corresponding to the single scan image, and record it as the second ink volume;
[0085] S21: Obtain the curing power corresponding to a single scan image based on the second ink volume, and record it as the second curing power;
[0086] S22: Perform pre-curing processing on the corresponding single-scan image according to the second curing power.
[0087] Preferably, the second curing power is less than the first curing power. This is because the second curing power is the power used in the pre-curing process, which can be lower, while the first curing power is used during the final curing process, allowing for a higher power in the final curing stage to ensure the image is ultimately cured. In other embodiments, the second curing power can be greater than the first curing power, allowing the image to be essentially cured during the pre-curing process, and the curing function to be optimized and adjusted during the final curing process for intelligent image curing.
[0088] Before curing each image unit, pre-curing is performed on each single printed portion of the image unit during printing to prevent ink diffusion and improve the printing quality.
[0089] In some embodiments, if the curing apparatus has a zone curing function, then the image unit can be divided into several sub-image units, and each sub-image unit can be cured in zones using different curing powers according to the ink volume corresponding to each sub-image unit. Specifically, this includes the following steps:
[0090] S40: Divide the image unit into several sub-image units;
[0091] S41: Obtain the ink volume corresponding to each sub-image unit, denoted as the third ink volume;
[0092] S42: Obtain the curing power corresponding to each sub-image unit based on the third ink volume, and record it as the third curing power;
[0093] S43: Perform solidification processing on the corresponding sub-image unit according to the third solidification power.
[0094] The step of performing solidification processing on the corresponding sub-image unit according to the third solidification power includes:
[0095] S431: Obtain the solidified area corresponding to each printed sub-image unit;
[0096] S432: Within the curing area, the corresponding sub-image unit is cured according to the third curing power.
[0097] For example, such as Figure 4 As shown, image unit A is divided into four sub-image units (A1, A2, A3, A4), and the corresponding curing device B can also be divided into four curing regions (B1, B2, B3, B4). Before curing image unit A, the ink volume of each sub-image unit is obtained, and the curing power corresponding to each sub-image unit is obtained according to the above mapping relationship of ink volume-curing power, denoted as the third curing power. Let the third curing power corresponding to sub-image unit A1 be P1, the third curing power corresponding to sub-image unit A2 be P2, the curing power corresponding to A1 be P1, the third curing power corresponding to A3 be P3, and the third curing power corresponding to A4 be P4. Then, when the image unit reaches the curing device B, curing region B1 uses curing power P1 to cure sub-image unit A1, curing region B2 uses curing power P2 to cure sub-image unit A3, and curing region B4 uses curing power P4 to cure sub-image unit A4.
[0098] Of course, the method of partitioning image units is not limited to... Figure 4 The examples given can also be as follows: Figure 5 or Figure 6 As shown, the area (size) of each sub-image unit can be equal or unequal, and the number of sub-image units can be set according to the actual printing situation. Accordingly, the curing device needs to be structurally adjusted to adapt its curing partitions to the partitioning method of the image units.
[0099] By performing partitioned curing on image units, the curing power can be intelligently adjusted to cure image areas with different ink volumes within the same image unit, thus avoiding insufficient or excessive curing due to uneven ink volume in different areas of the same image unit. This further ensures the curing effect of the image unit and improves image quality.
[0100] In summary, the intelligent curing method for inkjet printing provided by this invention divides the image to be printed into several image units, obtains the ink volume of each image unit, and determines the corresponding curing power based on the ink volume. After printing each image unit, the power of the curing device is adjusted according to the ink volume, achieving intelligent curing of the image unit and avoiding under- or over-curing, thus ensuring image quality. If the image unit is printed by multiple scans, further, pre-curing can be performed on each scan portion of the image unit during printing to prevent ink diffusion and improve print quality. After the image unit is printed, it undergoes zoned curing. For image areas with different ink volumes within the same image unit, the curing power is intelligently adjusted based on the ink volume to prevent under- or over-curing due to uneven ink volume in different areas of the same image unit, further ensuring the curing effect of the image unit and improving image quality.

[0135] In summary, the inkjet printing intelligent curing method, apparatus, device, and storage medium provided in this embodiment of the invention, specifically the inkjet printing intelligent curing method, divides the image to be printed into several image units, obtains the ink volume of each image unit, and determines its corresponding curing power based on the ink volume. After printing each image unit, the power of the curing device is adjusted according to the ink volume of the image unit to achieve intelligent curing of the image unit, avoiding under-curing or over-curing and ensuring image quality. If the image unit is printed by multiple scans, further, pre-curing processing can be performed on each scan portion of the image unit during printing to prevent ink diffusion and improve image printing quality. After the image unit is printed, it undergoes partitioned curing processing. For image areas with different ink volumes within the same image unit, the curing power can be intelligently adjusted according to their ink volume to prevent under-curing or over-curing due to uneven ink volume in different areas of the same image unit, further ensuring the curing effect of the image unit and improving image quality.
