Description

Technical Field

[0001] The present invention relates to the field of inkjet printing technology, and in particular to an inkjet printing method, device, equipment and storage medium based on multiple nozzles. Background Art

[0002] The process of printing images and texts by an inkjet printer is to convert the image data used as the printing target into print data that can be recognized by the inkjet printer after being processed by a raster image processor (RIP). The raster image processor then distributes the print data to the main control board of the inkjet printer. The main control board parses the received print data and distributes it to the nozzle control board. Finally, the nozzle control board controls the nozzle to perform inkjet printing based on the received print data. During the inkjet printing process, the main control board not only transmits the print data to the nozzle control board, but also transmits the print parameters to the nozzle control board for parameter configuration.

[0003] At present, in order to increase the printing speed, inkjet printers generally use multiple nozzles to work in parallel. When multiple nozzles work together, a large amount of printing data is required, and at the same time, it is necessary to ensure that the nozzles can discharge ink at the corresponding positions according to the printing data when they move to the corresponding positions. In the prior art, the consistency of the printing position is ensured when multiple nozzles work in parallel, but when a single nozzle among the multiple nozzles is used for printing, the initial printing position may change, and the consistency of the initial printing position cannot be guaranteed.

[0042] Example 1

[0043] See also Figure 1 , assuming that the left boundary of the current nozzle 1 (indicated by a dotted line) is exactly located at the boundary of the image printing area, in the prior art, when only nozzle 1 is selected, or nozzle 1 and nozzle 2 are selected at the same time, or nozzle 1, nozzle 2 and nozzle 3 are selected at the same time for printing, the printing start position is the position of the left boundary of nozzle 1 plus a preset white margin value, and when only nozzle 2 is selected or nozzle 2 and nozzle 3 are selected at the same time for printing, the printing start position is the position of the left boundary of nozzle 2 plus the preset white margin value, and when only nozzle 3 is selected for printing, the printing start position is the position of the left boundary of nozzle 3 plus the preset white margin value. The consistency of the printing start position cannot be guaranteed, resulting in deviations in the position of the printed image when switching different nozzle combinations for printing, reducing the printing quality and wasting printing media.

[0044] See also Figure 2 The embodiment of the present invention provides an inkjet printing method based on multiple nozzles, characterized in that the method is applied to a printer, the printer at least includes a first nozzle, a second nozzle and a third nozzle, and the method includes the following steps:

[0045] S1: determining an initial printing position according to the printing medium position information and a preset white margin value;

[0046] In this step, the initial printing position is first determined based on the print medium position information and the preset white margin value. The print medium position information can be obtained by manual input, or by positioning the print medium through the printer's position sensor or image sensor to automatically obtain the print medium position information. The preset white margin value is the white margin value set by the printing software during printing, and can be modified according to user needs.

[0047] S2: selecting a combination of one or more of the first nozzle, the second nozzle and the third nozzle to perform inkjet printing;

[0048] In the process of inkjet printing, an inkjet printer is usually equipped with only one type of nozzle. When using an inkjet printer to print multiple patterns of different colors on a print medium, the inkjet printer will often print a pattern of one color first, then change the printing ink, and then print another color pattern. It takes a certain amount of time for the inkjet printer to change the ink, which will result in a long pattern printing time and low printing efficiency of the inkjet printer;

[0049] By arranging multiple nozzles on the inkjet printer and using various nozzles to print patterns of different colors on the printing medium respectively, each nozzle for printing patterns of different colors can complete the ink preparation and cache of the data required for printing before the start of inkjet printing. During the printing process, various nozzles can be used for printing at any time, thereby improving the printing efficiency of the inkjet printer;

[0050] In this step, the nozzles required for inkjet printing are selected. The selection of the nozzles can be determined according to the printing requirements, for example, by the color of the image to be printed and the accuracy of the image to be printed. When the accuracy of the image to be printed is high, the first nozzle, the second nozzle and the third nozzle can be selected simultaneously for inkjet printing, which can improve the printing efficiency and printing accuracy. Alternatively, only one of the first nozzle, the second nozzle and the third nozzle can be selected for printing. The selection of the nozzles is not limited here.

[0051] In one embodiment, see Figure 1 The first nozzle, the second nozzle and the third nozzle are installed in a stepped manner. In the direction of nozzle movement, the first nozzle is located in front of the second nozzle, and the second nozzle is located in front of the third nozzle.

[0052] S3: According to the selected nozzle, adjusting the initial printing position to obtain the actual printing position;

[0053] After selecting the nozzle for inkjet printing, the initial printing position is adjusted according to the selected nozzle to ensure that the starting position of printing remains consistent when printing is performed using different nozzle combinations.

[0054] In one embodiment, see Figure 3 , the step S3 specifically includes:

[0055] S31: when the selected nozzles include only one nozzle, obtaining a nozzle distance between the first nozzle and the selected nozzle in the nozzle moving direction;

[0056] In this step, when the selected nozzles include only one nozzle, the nozzle spacing between the first nozzle and the selected nozzle in the nozzle moving direction is obtained. For example, when only the second nozzle is selected for printing, the spacing between the first nozzle and the second nozzle is obtained. When only the third nozzle is selected for inkjet printing, the nozzle spacing between the first nozzle and the third nozzle is obtained.

[0057] S32: when the selected nozzle includes a plurality of nozzles, obtaining a nozzle spacing between the nozzle closest to the first nozzle in the nozzle moving direction and the first nozzle;

[0058] In this step, when the selected nozzles include only multiple nozzles, the nozzle spacing between the nozzle closest to the first nozzle in the nozzle moving direction and the first nozzle is obtained. For example, when the second nozzle and the third nozzle are selected for printing at the same time, the second nozzle is the nozzle closest to the first nozzle in the nozzle moving direction, and the spacing between the first nozzle and the second nozzle is obtained. When the first nozzle and the second nozzle are selected at the same time or all the nozzles are selected for printing at the same time, since the selected nozzles include the first nozzle, the nozzle spacing is 0;

[0059] S33: adjusting the initial printing position according to the nozzle spacing to obtain the actual printing position.

[0060] After obtaining the nozzle spacing, the initial printing position is adjusted according to the nozzle spacing to obtain the actual printing position. In a specific embodiment, when the second nozzle is selected for inkjet printing or the second nozzle and the third nozzle are selected for printing at the same time, the nozzle spacing is to obtain the spacing between the first nozzle and the second nozzle, and the initial printing position is adjusted according to the first nozzle spacing to obtain the actual printing position, wherein the actual printing position is equal to the sum of the initial printing position and the first nozzle spacing.

[0061] In another specific embodiment, the third nozzle is selected for inkjet printing, the nozzle spacing is to obtain the spacing between the first nozzle and the third nozzle, and the initial printing position is adjusted according to the second nozzle spacing to obtain the actual printing position, wherein the actual printing position is equal to the sum of the initial printing position and the second nozzle spacing.

[0062] In a specific embodiment, only the first nozzle is selected, or the first nozzle and the second nozzle are selected at the same time, or the first nozzle, the second nozzle and the third nozzle are selected at the same time for inkjet printing. Since the selected nozzles include the first nozzle, the nozzle spacing is 0, and the actual printing position is the initial printing position, and no adjustment is required.

[0063] S4: Start inkjet printing at the actual printing position through the selected nozzle.

[0064] See also Figure 4 In one embodiment, step S4 specifically includes:

[0065] S41: for any one of the selected nozzles, setting a trigger parameter corresponding to the nozzle type for the nozzle according to the actual printing position, wherein the trigger parameter corresponding to the nozzle type is used to generate a trigger signal for causing the nozzle type to start ejecting ink;

[0066] S42: According to the trigger parameter corresponding to the selected nozzle, the selected nozzle is controlled to start ejecting ink at the actual printing position.

[0067] The printer uses channels as units when performing output printing. For any of the selected nozzles, the trigger parameters corresponding to the nozzle are set for the nozzle according to the actual printing position. The trigger parameters corresponding to the nozzle are used to generate a trigger signal for the nozzle to start spraying ink. If the trigger parameter is 0, it means that the printer will immediately perform inkjet printing once the task is established; if the trigger parameter is 10, the ignition printing will start after the counter has printed ten lines. By setting the trigger parameters, the printing position of the nozzle can be controlled to control the nozzle to perform inkjet printing at the specified position.

[0068] The multi-nozzle based inkjet printing method of the present invention determines the initial printing position according to the printing medium position information and the preset white margin value, selects one or more combinations of the first nozzle, the second nozzle and the third nozzle for inkjet printing, adjusts the initial printing position according to the selected nozzle to obtain the actual printing position, starts inkjet printing at the actual printing position through the selected nozzle, and can automatically obtain the actual printing position according to the initial printing position according to the nozzle selected for printing, thereby ensuring the consistency of the initial printing position when switching different nozzles for printing, thereby ensuring the image printing effect.

[0077] A second nozzle spacing acquisition unit, configured to acquire, when the selected nozzle includes a plurality of nozzles, a nozzle spacing between a nozzle closest to the first nozzle in the nozzle moving direction and the first nozzle;

[0078] The printing position adjustment unit is used to adjust the initial printing position according to the nozzle spacing to obtain the actual printing position.

[0079] The multi-nozzle based inkjet printing device of the present invention determines the initial printing position according to the printing medium position information and the preset white margin value, selects a combination of one or more of the first nozzle, the second nozzle and the third nozzle for inkjet printing, adjusts the initial printing position according to the selected nozzle to obtain the actual printing position, starts inkjet printing at the actual printing position through the selected nozzle, and can automatically obtain the actual printing position according to the initial printing position according to the nozzle selected for printing, thereby ensuring the consistency of the initial printing position when switching different nozzles for printing, thereby ensuring the image printing effect.
