[0040] Example 1

[0041] This invention provides a multi-processor-based inkjet printing method, apparatus, device, and storage medium to solve the technical problem of high complexity in existing inkjet printing and laser etching positioning methods.

[0042] like Figure 1 As shown, the present invention provides a multi-processor-based inkjet printing method for an inkjet printer, the inkjet printer comprising: at least one controller and a processor group, wherein the processor group comprises a plurality of first processors, and the controller is communicatively connected to each processor in the processor group;

[0043] S1. Obtain the image data to be printed and send it to the controller;

[0044] Specifically, the image data to be printed refers to the image data that needs to be printed on the substrate. It can be digital image data obtained from a computer, storage device, or other data source. The controller is a component in an inkjet printer that manages and coordinates the entire printing process. It communicates with each processor in the processor group, receiving the image data to be printed and sending it to the appropriate processor.

[0045] In this embodiment, the controller includes, but is not limited to, an FPGA, a central controller, and an IC. An FPGA is a programmable hardware device that can be adapted to different application requirements by reconfiguring its internal logic circuitry. This makes FPGAs highly flexible and allows for customization and optimization based on specific printing needs. The central controller is a dedicated control device used to manage and coordinate the work of multiple CPUs. It can allocate tasks, schedule computing resources, and handle communication and synchronization between multiple CPUs.

[0046] As an optional embodiment of this application, the controller is an FPGA or an IC. Since the FPGA performs tasks at the hardware level without the need for operating system or software intervention, it has lower processing latency. This is crucial for real-time control during the printing process, reducing response time and transmission latency, and improving printing accuracy and stability. The FPGA also has parallel processing capabilities, allowing it to execute multiple tasks or operations simultaneously. During printing, the FPGA can process multiple print data simultaneously, achieving efficient data processing and control. This is essential for real-time printing applications, improving printing speed and responsiveness.

[0047] Similarly, integrated circuits (ICs) can be used to replace FPGAs to control multiple processors. Using existing or specially designed ICs or other custom IC solutions may be more suitable. For the need to control multiple processors, a custom IC can be designed to implement specific control functions, which can achieve higher performance and a more compact solution without relying on the programmability of FPGAs.

[0048] In summary, the choice between FPGA and IC depends on specific application requirements and constraints. FPGAs offer flexibility and programmability, making them suitable for rapid prototyping, rapid iteration, and short-term production. ICs, on the other hand, are suitable for applications requiring high performance, low power consumption, high integration, and long-term production. Considering factors such as cost, performance, time, and resources, the most suitable solution can be chosen. Using an FPGA as a print controller offers advantages such as high customization, parallel processing, low latency, high reliability, and low power consumption. These characteristics make FPGAs widely used in industrial printing, high-speed printing, and complex printing applications, providing superior performance and reliability.

[0049] As an optional embodiment of this application, the processor group further includes a second processor, wherein the second processor is communicatively connected to the data source and the controller respectively, and the step of acquiring the image data to be printed and sending it to the controller includes:

[0050] S11. Obtain the image data to be printed from the data source and send it to the second processor;

[0051] S12. The image data to be printed is sent to the controller;

[0052] Specifically, in addition to the first processor, the processor group also includes a second processor. The second processor is responsible for communicating with the data source to acquire the image data to be printed and sending it to the controller. The data source is the place where the image data to be printed is stored; it can be a computer, storage device, or other data source. By introducing the second processor and communicating with the data source, the image data to be printed can be obtained directly from the data source, avoiding delays and interruptions during data transmission. This helps improve the real-time performance and reliability of the data. Furthermore, while the second processor is responsible for data acquisition and transmission, the controller is responsible for further processing and scheduling for subsequent rasterization and inkjet printing. This division of labor and collaboration can improve the overall efficiency and stability of the printing process.

[0053] S2. The image data to be printed is divided into multiple sub-printed image data;

[0054] In this step, the image data to be printed is divided into multiple sub-print image data. This is done to break down the printing task into smaller parts so that each processor can process one of the sub-print image data in parallel;

[0055] Specifically, the image data to be printed is first divided into multiple regions, each corresponding to a sub-printed image data. This division can be based on the image's pixel coordinates or other specific rules to ensure each region is of appropriate size and evenly distributed. Each region is then segmented and converted into appropriate data blocks. Segmentation can be performed according to the printer's processing capabilities and communication requirements, ensuring each data block is of suitable size and easy to process and transmit. Next, each data block is encapsulated, adding necessary identification and control information for subsequent processing and transmission. This can include the data block's identifier, sequence number, checksum, etc., to ensure data integrity and accuracy. Finally, the encapsulated sub-printed image data is transmitted to the corresponding processor for further processing. Transmission can be performed through a high-speed data communication interface or other appropriate transmission methods to ensure timely arrival and reliable transmission of data.

[0056] By dividing the image data to be printed into multiple sub-printed image data and processing them in parallel using multiple processors in the processor group, the speed of rasterization processing can be accelerated, and the printing efficiency can be improved. After the image data to be printed is processed in packets, the size of each sub-printed image data is moderate, which reduces the transmission latency and load of a single data packet and improves the efficiency and stability of data transmission.

[0057] As an optional embodiment of this application, the step of sub-packaging the image data to be printed to obtain multiple sub-printed image data includes:

[0058] S21. Obtain the actual number of the first processors;

[0059] In this step, the actual number of first-order processors available in the current system is obtained. This can be obtained through system configuration or dynamic detection at runtime.

[0060] S22. Based on the actual quantity, the image data to be printed is divided into packets to obtain a target number of sub-printed image data, wherein the target quantity is the same as the actual quantity;

[0061] In this step, the image data to be printed is divided into packets based on the actual number of the first processors to obtain a target number of sub-printed image data, which is the same as the actual number of processors. The packet division can be performed according to the principle of uniform division to ensure that each sub-printed image data is of similar size.

[0062] By processing multiple sub-print image data in parallel, rasterization and printing operations can be performed simultaneously. Compared to processing each sub-print image data sequentially, parallel processing can significantly accelerate printing speed and shorten printing time.

[0063] Distributing print data evenly across each processor achieves load balancing. This ensures each processor handles a relatively balanced amount of data, preventing overload of any single processor and improving system stability and efficiency.

[0064] S23. Distribute the target number of sub-print data to each of the first processors.

[0065] In this step, the target number of sub-printed image data is allocated to each first processor. Each processor will be responsible for processing its assigned sub-printed image data and performing rasterization.

[0066] Dividing the print data into sub-print image data packets, the same number as the first processor, fully utilizes the processing power of each processor. Each processor can process its assigned sub-print image data in parallel, maximizing the use of processor resources in the system.

[0067] S3. Each of the first processors performs rasterization processing on the corresponding sub-printed image data to obtain multiple rasterized images;

[0068] Specifically, rasterization refers to the process of converting continuous image data into discrete pixels or dot matrices. In inkjet printing, rasterization converts image data into an arrangement of ink dots that the printhead can recognize and eject. Each sub-printed image data needs to be rasterized to generate a corresponding rasterized image;

[0069] By rasterizing the sub-printed image data corresponding to each first processor, continuous image data can be converted into discrete pixel representations, generating a rasterized image. This processing scheme can adapt to the printhead's operating mode and provide the necessary inkjet commands and data to achieve accurate printing results.

[0070] S4. Based on each rasterized image, perform inkjet printing to obtain the target image.

[0071] Inkjet printing from each rasterized image is a crucial step, achieving accurate reproduction of patterns and text by controlling the inkjet position and intensity of the printhead. This step requires controlling the inkjet mechanism to complete the inkjet operation according to the instructions of the rasterized images, and repeating the process for each rasterized image until all images have been inkjet printed. This process ensures printing precision, accuracy, and efficiency.

[0072] As an optional embodiment of this application, the step of inkjet printing based on each rasterized image to obtain a target image includes:

[0073] S41. After each of the first processors completes the rasterization processing of the sub-printed image data, the resulting rasterized image is sent to the controller.

[0074] S42. Each of the rasterized images is stitched together to obtain the target printing data;

[0075] Specifically, stitching ensures that multiple rasterized images are correctly combined in a predetermined order and position to form a continuous and complete target print data. This avoids broken or discontinuous patterns during printing. Stitching also ensures smooth transitions between adjacent rasterized images, resulting in no obvious transition lines or defects between different parts of the printed pattern. This improves print quality and appearance consistency.

[0076] S43. Perform inkjet printing based on the target printing data to obtain the target image.

[0077] As an optional embodiment of this application, the inkjet printer further includes: multiple printhead driver boards and multiple printheads, and the step of performing inkjet printing based on the target printing data to obtain a target image includes:

[0078] S431. Obtain the nozzle parameters for each nozzle, wherein the nozzle parameters include nozzle arrangement information, nozzle layout information, and printing accuracy;

[0079] Specifically, nozzle arrangement information specifies the position and arrangement of the nozzles on the printhead, determining the accuracy and resolution of ink ejection; printhead layout information determines the position and arrangement of the printhead in the printer, used to precisely control the ink ejection position and coverage. Print accuracy indicates the accuracy and resolution of the printhead, i.e., the number of dots printed per inch (or per millimeter);

[0080] S432. Based on the printhead parameters of each printhead, the target printing data is allocated to each printhead driver board to drive the corresponding printhead to perform inkjet printing.

[0081] The purpose of allocating target print data to each printhead driver board based on the printhead parameters is to achieve precise inkjet control and optimize print quality. The layout of the printheads on the printer determines the effective range and coverage area of ​​each printhead. By allocating target print data to the corresponding printhead driver board, each printhead can be responsible for its specific area, ensuring the consistency and balance of the entire pattern. This avoids uneven ink distribution or color differences during the printing process.

[0082] Different printheads have different printing precisions, that is, the number of dots printed per inch (or millimeter). By allocating the target print data to the corresponding printhead driver board according to the printing precision of each printhead, the detail and resolution of the print can be controlled as needed. This enables high-precision printing, ensuring clear details and accurate color output.

[0083] By acquiring printhead parameters and allocating target print data to the corresponding printhead driver board, inkjet printers can perform precise inkjet operations based on printhead characteristics and requirements. This ensures print quality and accuracy, achieving high-resolution, high-speed, and high-efficiency inkjet printing to meet the needs of various application scenarios.

[0084] As an optional embodiment of this application, one nozzle drive board corresponds to one or more nozzles;

[0085] Specifically, each printhead driver board independently controls one printhead, making the control system simpler and easier to manage. The position, angle, and parameters of each printhead can be adjusted as needed to adapt to different printing requirements.

[0086] When one printhead driver board corresponds to multiple printheads, these printheads can work simultaneously, increasing printing speed and production efficiency. Sharing a single driver board reduces the number of hardware and devices in the system, saving costs and space. Whether to select one printhead driver board for one printhead or one printhead driver board for multiple printheads depends on specific printing needs and system design. A single printhead driver board is suitable for situations requiring precise control and flexible configuration, while multiple printhead driver boards are suitable for situations requiring improved production efficiency and cost savings.

[0087] In one embodiment, the inkjet printer further includes a display device, which is communicatively connected to a second processor and is used to display a human-machine interface for selecting print data, controlling machine operation, etc. All operations are performed through a touch screen, and the display device can be a touch screen.

[0088] In summary, the beneficial effects of this application are as follows:

[0089] The multi-processor-based inkjet printing method of this application enables parallel processing of the image data to be printed by employing a processor group composed of multiple first processors. Each processor is responsible for processing one sub-printed image data, thereby greatly improving the efficiency and speed of data processing. After the image data to be printed is processed in packets, each sub-printed image data is rasterized by its corresponding first processor. This packetization and rasterization processing method can better utilize the parallel computing power of the multi-processor, allowing the rasterization process to be performed simultaneously, thus accelerating the image data processing speed. The controller communicates with each processor in the processor group to realize data transmission and collaborative work. This parallel communication mechanism allows the controller to send multiple sub-printed image data to different processors simultaneously, thereby managing and scheduling the entire printing process more efficiently.
