Description

[0001] This application is a divisional application of the invention patent application with the application number 202110877221.7, titled "Intensive Inkjet Printing Method, Device and Equipment with Random Distribution of the Position of the Printed Matter", which was filed on July 31, 2021. Technical Field

[0002] The present invention relates to the technical field of inkjet printing, and in particular to a method, device and equipment for self-adaptive intensive inkjet printing of the position and pose of the printed matter. Background Art

[0003] Inkjet printing technology refers to the technology of ejecting ink droplets onto a printing medium through nozzles on a print head to obtain images or text. Compared with the traditional screen printing process that requires 13 processes such as stretching the screen, printing, and baking, inkjet printing technology only requires 4 processes such as inkjet printing and baking, which can effectively save the processes of making the screen and baking the text, and is more economically beneficial than traditional screen printing in terms of production cost and production efficiency.

[0004] In a traditional digital inkjet printing system, it is basically necessary to fix the position of the printing medium for printing. If the printing medium is placed randomly, or several printing media are placed randomly on the carrier of the printed matter, accurate printing cannot be achieved. Recently, digital inkjet printers have an accurate CCD automatic alignment function, which can automatically adjust the size of the graphic according to the different sizes of the printing medium, so that the size of the digital graphic to be printed matches the actual size of the printing medium. However, existing inkjet printers can only print on one piece of printing medium at a time. After the image on the printing medium is printed, the next printing medium is repositioned and the corresponding image is printed. Repositioning is required for printing images on each piece of printing medium, resulting in low printing efficiency. Summary of the Invention

Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, the elements defined by the statement "comprising..." do not exclude the presence of additional identical elements in the process, method, article or device comprising the said elements.

[0047] Please refer to Figure 1 , an embodiment of the present invention provides an intensive inkjet printing method with randomly distributed printing substrates. The number of the printing substrates is at least two, and each printing substrate is simultaneously distributed at different positions on the printing substrate carrier. The method only needs to take a single shot of all the printing substrates located on the printing substrate carrier. After the shooting is completed, the printing files corresponding to the printing substrates are automatically obtained, saving the positioning time during the printing process of the printing substrates, improving the printing efficiency. At the same time, after the shooting is completed, the image printing files are processed such as rotation and / or scaling according to the contour information of each printing substrate, ensuring the accuracy of image printing. At the same time, it also reduces the operation difficulty of placing multiple printing substrates, saves the time for precise placement, and makes the placement of the printing substrates more flexible. The intensive inkjet printing method with randomly distributed printing substrates specifically includes the following steps:

[0048] S1. Obtain the position information and contour information of each printing substrate located on the printing substrate carrier;

[0049] In one embodiment, taking the geometric center of the printing substrate carrier as the origin, the reciprocating movement direction of the print head as the X-axis, the stepping direction of the print head as the Y-axis, a plane coordinate system or a three-dimensional coordinate system is established with the plane where the printing substrate carrier is located. Please refer to Figure 2 , and the specific content of S1 includes:

[0050] S11. Obtain an image including all the printing substrates on the printing substrate carrier;

[0051] S12. Obtain the contour information corresponding to each printing substrate based on the image;

[0052] S13. According to the contour information of each printing substrate, when each printing substrate is a thin sheet medium, obtain the coordinate data of each printing substrate in the plane coordinate system; when at least one of each printing substrate is a non-thin sheet medium, obtain the coordinate data of each printing substrate in the three-dimensional coordinate system.

[0053] Specifically, by controlling the CCD camera to capture an image of all the printing materials on the printing material carrier, filtering the captured image to filter out some noise in the image, using a second-order gradient Canny edge detection operator to extract the edges of the target image, and extracting contour information based on a contour extraction algorithm. The contour information includes the coordinate parameters of the contour points, which are used as the position information of each printing material. In the present invention, all coordinate systems are plane coordinate systems or three-dimensional coordinate systems constructed based on the printing material carrier. When all the printing materials on the printing material carrier are thin sheet media, that is, the thickness of each printing material is consistent, a plane coordinate system is established. The thin sheet media can be printed circuit boards, radio frequency tags, identification cards, paper, etc. This is only an example and not a limitation here. When at least one of the printing materials is a non-thin sheet media, that is, when the thicknesses of the printing materials are inconsistent, a three-dimensional coordinate system is established to obtain the thickness, that is, the height information of each printing material. The coordinate origin can be set as needed. For example, the geometric center of the printing material carrier can be selected as the coordinate origin, or the starting printing position on the printing material carrier can be selected as the coordinate origin. These can all be determined according to the actual printing needs and calculation needs. The reciprocating movement direction of the print head is used as the X-axis of the coordinate system, and the stepping direction of the print head is used as the Y-axis of the coordinate system;

[0054] S2. According to the contour information of each printing material, process the printing data of the corresponding printing file for each printing material so that the position of the ink droplets ejected on each printing material is consistent with the desired ink ejection position on the printing material;

[0055] In one embodiment, the S2 includes:

[0056] S21. According to the contour information of each printing material, obtain the rotation angle and / or scaling factor of the corresponding printing file for each printing material;

[0057] S22. Process the printing file according to the rotation angle and / or the scaling factor to obtain a corresponding file to be printed;

[0058] In one embodiment, before step S21, the method further includes obtaining the corresponding printing file for each printing material through the contour information of each printing material;

[0059] Specifically, after obtaining the contour information of each substrate, several preset printing files are matched through the contour information of each substrate. The printing file includes dot matrix data for printing. By depicting the dot matrix data in an image file, coordinate data of each image can be obtained in the image file. Based on the correspondence between the coordinate data of each contour point in the contour information and the coordinate data of the image, the rotation angle and / or the scaling factor are determined, where the rotation angle and / or the scaling factor are derived based on the extreme value conditions that need to be satisfied when the coordinate data of each contour point and the coordinate data of its corresponding image are minimized.

[0060] In one embodiment, referring to Figure 3 , S22 specifically includes:

[0061] S221. Establish an affine transformation matrix according to the rotation angle and / or the scaling factor;

[0062] S222. Perform data processing on the image printing file according to the affine transformation matrix;

[0063] Among them, the affine transformation matrix is:

[0064] {cos(θ)*α, sin(θ), 0, -sin(θ), cos(θ)*β, 0}

[0065] In the formula, θ is the rotation angle, α is the scaling factor of the coordinate data in the X direction in the printing file, and β is the scaling factor of the coordinate data in the Y direction in the printing file;

[0066] Let the original coordinate data of any image be (X, Y), and the new coordinate of the image after being processed by the affine transformation matrix is (X', Y');

[0067] Among them, X' = cos(θ)*α*X + sin(θ)*Y;

[0068] Y' = -sin(θ)*X + cos(θ)*β.

[0069] In this embodiment, the image in the parsed printing file is rotated and scaled according to the rotation angle and the scaling factor to obtain a to-be-printed image that matches the substrate. In this way, accurate printing of substrates at any placement position and any size can be achieved. For example, Figure 4 during the process of parsing the printing file and converting it into a bitmap that can be printed by the printer, such as obliquely placed or upside-down, the image printing file can be quickly rotated and scaled, so as to accurately print the image to the accurate position of the substrate and improve the image printing accuracy;

[0070] S3. Obtain the printing data position information of the processed printing files relative to the substrate carrier according to the position information of each substrate on the substrate carrier;

[0071] S4. Output the printing data of each printing file for inkjet printing on the corresponding substrate according to the printing data position information.

[0072] Specifically, according to the position information of each substrate on the substrate carrier, obtain the printing data position information of the processed printing files relative to the substrate carrier. When the position information of each substrate on the substrate carrier is two-dimensional coordinate information, the two-dimensional coordinate information of each substrate on the substrate carrier can be directly used as the corresponding printing data position information; when the position information of each substrate on the substrate carrier is three-dimensional coordinate information, that is, the thicknesses of the substrates are inconsistent. At this time, if the printing data position information is not adjusted, during printing, due to the height difference between the substrates, the printed image will be offset. The offset can be calibrated by obtaining a calibration value based on the thickness of each substrate and the moving speed of the nozzle, and adjusting the corresponding printing data position information according to the calibration value; in another embodiment, the offset caused by the inconsistent thickness can also be adjusted by setting trigger parameters, so that the printing data of each printing file can be inkjet printed on the corresponding substrate without offset.

[0073] In one embodiment, step S4 specifically includes:

[0074] S41: Arrange the printing data of all the to-be-printed files on the canvas in a preset order according to the printing data position information to obtain a first to-be-printed file;

[0075] S42: Perform inkjet printing on all the substrates according to the first to-be-printed file.

[0076] Specifically, during printing, first arrange the printing data of the to-be-printed files on a canvas in a preset order according to the printing data position information to obtain a first to-be-printed file. The size of the canvas is the same as that of the substrate carrier. During printing, directly perform inkjet printing according to the printing data of the first to-be-printed file, and thus the printing of multiple substrates can be completed at one time. Since the first to-be-printed file is obtained by arranging according to the printing data position information, when printing the first to-be-printed file, the corresponding image or text can be accurately printed on each substrate.

[0077] In another embodiment, before step S41, it further includes arranging all the files to be printed and obtaining the minimum bounding rectangle after arranging all the files to be printed, obtaining a canvas with the same size as the minimum bounding rectangle in the image processing software. Using the minimum bounding rectangle saves the data processing time for stitching images, improves the data processing efficiency, and since the canvas size is reduced, it saves the travel distance of the printing carriage's reciprocating movement, further improving the printing efficiency.

[0078] The intensive inkjet printing method with randomly distributed substrate positions in this embodiment obtains the position information and contour information of each substrate on the substrate carrier; according to the contour information of each substrate, processes the printing data of the corresponding printing file for each substrate so that the position of the ink droplets ejected on each substrate is consistent with the desired ink ejection position on the substrate, making the image or text to be printed on each substrate match the size, inclination, and position of the substrate, ensuring the accuracy of printing the image or text on the substrate; secondly, according to the position information of each substrate on the substrate carrier, obtains the printing data position information of the processed printing files relative to the substrate carrier, and according to the printing data position information, outputs the printing data of each printing file for inkjet printing on the corresponding substrate, ensuring that the printing data of each file to be printed corresponds to the position of the corresponding substrate on the substrate carrier, making the positioning of the substrate more flexible, reducing the operation difficulty of positioning multiple substrates, saving the positioning time, and enabling simultaneous printing of substrates with the same shape or different shapes, improving the printing flexibility and printing efficiency.
