The invention discloses an ink-jet printer nozzle anomaly compensation method, device and equipment and a storage medium. The method comprises the steps that position information of an abnormal nozzlein spray heads is determined; printing parameters are acquired, first printing data corresponding to the abnormal nozzle is determined, and compensation nozzle position information corresponding to the first printing data for compensating for the abnormal nozzle in the spray heads is determined according to the abnormal nozzle position information and the printing parameters; according to the printing parameters, second printing data corresponding to the compensation nozzle during normal printing is acquired, wherein the second printing data comprises ink output data and non-ink output data;the address of the non-ink output data in the second printing data is determined, and the first printing data is corresponding written into the address of the non-ink output data to generate compensation data; and the ink output data of the second printing data and the compensation data are output to the compensation nozzle. According to the technical scheme, the problem that the image quality becomes poor due to ink output anomaly of the abnormal nozzle is solved, and spray head maintenance cost is reduced.
Description
technical field [0001] The invention relates to the technical field of inkjet printing, in particular to a method, device, equipment and storage medium for compensating abnormality of inkjet printer nozzles. Background technique [0002] Inkjet printing refers to spraying ink droplets onto the printing medium through the nozzles on the nozzle to obtain images or text. Reciprocating scanning printing technology is a commonly used technology in the field of inkjet printing at present. Reciprocating scanning printing is also called 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 and printing, each unit is composed of 2 pixels, and 3pass scanning and printing, each unit is composed of 3 pixels. Such as figure 1 It is the principle diagram of 4pass scanning and printing. A certain ...
