[0042] The features and exemplary embodiments of each aspect of the present application will be described in detail below, in order to make the purpose, technical solutions and advantages of the present application more clear and apparent, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present application, and are not configured to limit the present application. The present application can be implemented without some of these specific details for those skilled in the art. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.
[0043] It should be noted that in this paper, the relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device. Without more limitation, the elements defined by the statement "include" do not exclude the presence of other identical elements in the process, method, article or device including the elements.
[0044] Embodiment 1
[0045] The inkjet nozzle of the printing device is composed of a plurality of nozzles arranged in one or more columns longitudinally, which determines that the inkjet nozzle has a fixed resolution, i.e., an inherent resolution. For example, the resolution of a certain nozzle is 300 DPI, etc., i.e., there are 300 nozzles per inch.
[0046] As shown in Figure 1 , the printing of a high-resolution image can be completed by printing back and forth by the inkjet nozzle multiple times. For example, the image with a resolution of 600 DPI is printed by using the nozzle with a resolution of 300 DPI, and the nozzle needs to be printed twice by scanning twice to completely print the image data. As shown in Figure 1 , the triangle and the circle both represent one ink dot sprayed by the nozzle. The nozzle can print the image formed by the dots represented by the circle in the figure by one scanning, and the resolution of the pattern is 300 DPI. On this basis, the nozzle can print the dots represented by the triangle in the figure by one scanning again, and finally the two kinds of dots form an image with a resolution of 600 DPI. The specific printing process can be that the nozzle scans and prints the dots represented by the circle in the figure first, and then scans and prints the dots represented by the triangle in the figure after moving a certain distance along the longitudinal direction in the figure, and the distance is the inkjet step distance. The foregoing process needs to be scanned and printed twice, and therefore the initial scanning number of the printing is 2. If each scanning and printing is regarded as one PASS, the printing is 2PASS printing.
[0047] On the basis of the foregoing printing method, the application provides an inkjet printing method based on data splitting, which comprises the following steps:
[0048] S1, splitting the initial printing data according to the image to be printed to obtain contour printing data and filling printing data;
[0049] Specifically, first, the initial printing data is split according to the image to be printed to obtain contour printing data and filling printing data, wherein the contour printing data is used to print the contour in the image to be printed, i.e., the boundary of the object in the image to be printed, and the filling printing data is used to print the closed area in the contour in the image to be printed.
[0050] In an embodiment, the edge of the image to be printed can be detected to obtain contour information, and an edge detection algorithm such as Canny edge detection or Sobel algorithm can be used to perform morphological processing, such as inflation or closing operation, on the edge information to fill the holes in the contour and connect the broken contour lines to obtain a complete contour image. An image segmentation algorithm, such as threshold segmentation, region growing algorithm, etc., is used to segment the image to be printed into a contour image and a filling area image. During the segmentation process, according to the characteristics of the contour image, the pixel points or regions belonging to the contour are allocated to the contour image, and other pixel points or regions are allocated to the filling area image.
[0051] Subsequently, the obtained contour image and the filled region image are rasterized respectively to obtain contour printing data and filling printing data; however, this method is relatively cumbersome, and image segmentation is required to obtain the contour image and the filling image, and two rasterization processes are required, which is relatively low in efficiency;
[0052] To solve the above problems, as an optional embodiment of the present application, the step of splitting the printing data according to the to-be-printed image to obtain contour printing data and filling printing data comprises:
[0053] S11, edge detection is performed on the to-be-printed image according to a preset edge detection algorithm to obtain a contour image;
[0054] Specifically, the preset edge detection algorithm comprises a Canny edge detection algorithm, a Sobel algorithm, and a Roberts algorithm; the Canny algorithm is a classical edge detection algorithm, has good noise resistance and accurate edge positioning, and its steps comprise Gaussian filtering, gradient amplitude and direction calculation, non-maximum suppression, and double-threshold processing; the Sobel algorithm is a simple and commonly used edge detection algorithm. It detects edges by calculating the gradient of the pixel points in the image, and has the characteristics of simplicity and efficiency; the Roberts algorithm is an algorithm that detects edges based on the difference operation of the pixel neighborhood. It determines the edge position by calculating the difference of the pixel values in the neighborhood.
[0055] According to the selected preset edge detection algorithm, edge detection is performed on the to-be-printed image. The algorithm will find the possible edge position according to the gray value change in the image and mark it as an edge. According to the edge detection result, a contour image is generated.
[0056] Through edge detection, contour information can be extracted from the to-be-printed image. The contour image will only contain the information of the object boundary in the image, and the details of other regions are removed. This helps the extraction and processing of the contour printing data in the subsequent steps;
[0057] S12, corresponding data is extracted from the initial printing data according to the contour image to obtain contour printing data;
[0058] Specifically, the initial printing data is obtained by rasterizing the to-be-printed image, and is usually pixel data represented in bitmap form. It is necessary to ensure that the size of the contour image and the initial printing data is the same to maintain a one-to-one correspondence relationship. Each pixel point in the contour image corresponds to the corresponding position in the initial printing data, and the corresponding data can be extracted according to the contour image to obtain the contour printing data;
[0059] As an optional embodiment of the present application, the step of extracting corresponding data from the initial printing data according to the contour image to obtain contour printing data comprises:
[0060] S121, obtaining position information of each pixel in the contour image in the image to be printed;
[0061] In this step, the position information of each pixel point in the contour image in the image to be printed needs to be obtained, which can be achieved by traversing the pixel points of the contour image. For each pixel point in the contour image, its row and column coordinates can be obtained, which can be directly mapped to the corresponding position in the image to be printed. For example, the pixel point (x, y) in the contour image corresponds to the corresponding position (x, y) in the image to be printed.
[0062] S122, extracting corresponding data from the initial printing data according to the position information of each pixel to obtain contour printing data.
[0063] Specifically, the position information of each contour image pixel point obtained in step S121 is used to extract corresponding data from the initial printing data to obtain contour printing data. The specific operation is as follows:
[0064] 1) traverse each pixel point of the contour image;
[0065] 2) for each pixel point (x, y) in the contour image, find the corresponding position in the initial printing data according to its position information;
[0066] 3) extract the corresponding value or pixel information in the initial printing data according to the position as part of the contour printing data. It can be color value, gray level, or other data representing printing attribute;
[0067] 4) record or save the extracted data to gradually build the contour printing data;
[0068] Through the above steps, the corresponding data can be extracted from the initial printing data according to the position information of each contour image pixel point in the image to be printed to obtain the contour printing data. The purpose of this is to associate the edge position in the contour image with the initial printing data, so as to construct printing data containing only contour information, so as to realize subsequent inkjet printing and solidification operation.
[0069] S13, taking the initial printing data after extracting the contour printing data as the filling printing data.
[0070] The data obtained after extracting the contour printing data from the initial printing data is the filling printing data, which can be used for inkjet printing and solidification in the internal area of the contour image to realize accurate printing of the filling part of the image.
[0071] In this embodiment, the edge detection algorithm is used to detect the edges of the image to be printed, which can more accurately extract the contour information. Compared with the simple image segmentation method, the edge recognition can more accurately capture the contour line of the image. In the process of extracting the contour printing data, the corresponding data is directly extracted from the initial printing data, which ensures the size and spatial position of the contour printing data and the filling printing data. This can avoid the problem of data mismatch caused by errors in the image segmentation and rasterization process. The scheme integrates the extraction of contour printing data and the generation of filling printing data, simplifying the process. Compared with the scheme of segmenting the image and performing rasterization, one processing process is reduced, improving the efficiency. By directly extracting the initial printing data as the filling printing data, the additional image segmentation and rasterization process is avoided, reducing the demand for computing resources and storage space.
[0072] S2, performing inkjet printing and curing according to the contour printing data to obtain a contour image;
[0073] S3, performing inkjet printing and curing on the contour image according to the filling printing data to obtain a target printing image.
[0074] As an optional embodiment of the present application, the step of performing inkjet printing and curing according to the contour printing data to obtain a contour image comprises:
[0075] S21, performing inkjet printing according to the contour printing data to obtain an initial contour image;
[0076] S22, curing the initial contour image to obtain a contour image.
[0077] As an optional embodiment of the present application, the step of performing inkjet printing and curing on the contour image according to the filling printing data to obtain a target printing image comprises:
[0078] S31, performing inkjet printing on the contour image according to the filling printing data to obtain an initial printing image;
[0079] S32, curing the initial printing image to obtain a target printing image.
[0080] Specifically, in the present embodiment, first, inkjet printing is performed according to the contour printing data to obtain a contour printed image. The nozzles on the inkjet head are arranged according to the preset printing path, and ink droplets are sprayed onto the printing medium. The inkjet head can control the ink ejection of the nozzles according to the information of the contour printing data, so that the ink droplets are only sprayed to the edge area of the contour image. After inkjet printing, the ink is cured using a curing technology (such as ultraviolet irradiation or thermal curing), so that it is fixed on the printing medium and forms a visible contour image.
[0081] After inkjet printing, the ink is cured using a curing technology (such as ultraviolet irradiation or thermal curing), so that it is fixed on the printing medium and forms a visible contour image. After inkjet printing, the ink is cured using a curing technology, so that it is fixed on the printing medium and forms a complete target printed image.
[0082] Through the above scheme, first, data splitting is performed according to the to-be-printed image to obtain contour printing data and filling printing data. Then, inkjet printing and curing are performed on the contour printing data through step S2 to obtain a contour image. Next, inkjet printing and curing are performed on the contour image according to the filling printing data through step S3 to obtain a final target printed image. This scheme can realize accurate printing of the contour and filling parts of the image respectively, and ensure that the printed result is clear and distinguishable.
[0083] In the above scheme, since curing is performed after the contour image printing is completed, and the printing of the filling area is finally performed, there may be a problem of low printing efficiency; on the basis of reciprocating scanning printing, this problem can be improved;
[0084] As an optional embodiment of the present application, the inkjet printing and curing according to the contour printing data to obtain a contour image comprises:
[0085] S021, inkjet printing is performed along a first reciprocating scanning printing direction according to the contour printing data;
[0086] S022, curing is performed during the inkjet printing process to obtain a contour image;
[0087] Specifically, first, printing is performed according to the contour printing data along a first reciprocating scanning printing direction, and curing is also performed simultaneously during the printing process. By performing curing during the inkjet printing process, the ink can be quickly cured to prevent the ink from spreading or blurring on the printing medium. In this way, the clarity and stability of the contour image can be ensured, and ink bleeding or blurring can be avoided.
[0088] As an optional embodiment of the present application, the step of performing inkjet printing and curing on the contour image according to the filling printing data to obtain a target printed image comprises:
[0089] S031, according to the filling printing data, inkjet printing is performed on the contour image along a second reciprocating scanning printing direction, wherein the second reciprocating scanning printing direction is opposite to the first reciprocating scanning printing direction;
[0090] S032, curing is performed in the process of inkjet printing to obtain a target printed image.
[0091] Specifically, according to the filling printing data, printing is performed on the contour image along a second reciprocating scanning printing direction, and the second reciprocating scanning printing direction is opposite to the first reciprocating scanning printing direction; in this embodiment, high-power curing is started during the printing process to accelerate the curing process and improve the printing efficiency, and this method can reduce the printing time.
[0092] In summary, according to the data splitting based on the image to be printed, the initial printing data is split to obtain contour printing data and filling printing data, the original data is separated according to the contour information of the image, so that the subsequent processing can be performed on the contour part and the filling part of the image respectively; then, according to the contour printing data, inkjet printing and curing are performed to obtain a contour image, the contour part has a clear printing effect, and through the curing process, the ink is quickly dried to avoid the problems of blur or difficulty in identification of the contour part; finally, according to the filling printing data, inkjet printing and curing are performed on the contour image to obtain a target printed image, the printing and curing process of the contour printing data will ensure that the boundary of the image is clear and accurate, and the gradual printing of the filling printing data will gradually present the filling area, which can effectively avoid the color mixing and penetration phenomenon and improve the details of the filling area.
