Embodiment 1
[0051] Specifically, see image 3 , the step S1 also includes:
[0052] S111. Acquire nozzle arrangement information, and generate a reference nozzle state diagram according to the nozzle arrangement information;
[0053] S112. Obtain reference image data corresponding to the reference nozzle state map, and control the nozzle to spray ink on the printing medium according to the reference image data to obtain an actual nozzle state map;
[0054] S113. According to the actual nozzle state map and the reference nozzle state map, determine whether the shower head has abnormal nozzles.
[0055] When an abnormal nozzle is detected in the print head, the abnormal state of the abnormal nozzle is determined according to the detection result. Preferably, the abnormal nozzle includes one or more of oblique spraying, emptying, clogging, and insufficient ink. When there is only one kind of blocked nozzle in the abnormal nozzle, it is not necessary to write the non-inking data into the pr...
Embodiment 2
[0066] see Figure 5 , in a specific embodiment, the step S1 also includes:
[0067] S121. Obtain the detection time for detecting each nozzle, and calculate and obtain the ink ejection start time and ink ejection stop time of each nozzle of the nozzle according to the detection time;
[0068] S122. According to the start time of ink ejection and the stop time of ink ejection of each nozzle, send a detection signal through the expected ejection trajectory of each nozzle, and the expected ejection trajectory is the ejection trajectory of ink droplets when the nozzle is normal motion trajectory;
[0069] S123. Control each nozzle to eject ink and obtain a feedback signal after the detection signal passes through the expected ejection trajectory of each nozzle;
[0070] S124. Determine whether each nozzle of the shower head is abnormal according to the feedback signal.
[0071] Specifically, as Figure 6 , the inkjet situation of each nozzle on the nozzle is detected by the t...

Abstract
The invention discloses a spraying head and nozzleabnormality treatment method, device and equipment and a storage medium. The spraying head and nozzleabnormality treatment method comprises the steps of: detecting if abnormal nozzles are in spraying heads; if so, obtaining position information of the abnormal nozzles; determining printing data addresses corresponding to the abnormal nozzles according to the position information of the abnormal nozzles; and writing non-ink outlet data into the printing data addresses corresponding to the abnormal nozzles. Through writing of the non-ink outletdata into the printing data addresses corresponding to the abnormal nozzles, the method prevents weak quality of printing products caused by ink spraying of the abnormal nozzles.
Description
technical field [0001] The present invention relates to the technical field of inkjet printing, in particular to a processing method, device, equipment and storage medium for abnormal nozzles of a nozzle. Background technique [0002] Inkjet printing technology refers to the technology of spraying ink droplets onto the printing medium through the nozzles on the nozzle to obtain images or texts, mainly including reciprocating scanning printing, one-time scanning printing, multi-nozzle side-by-side scanning printing, etc., reciprocating scanning printing Also known as multi-pass scanning printing, multi-pass scanning printing means that each unit of the image to be printed needs to be interpolated multiple times before printing can be completed. Each unit is composed of multiple pixels, such as 2pass scanning printing. A unit is composed of 2 pixels, and for 3pass scanning printing, each unit is composed of 3 pixels; one-time scanning printing is also called single-pass scanni...
