The embodiment of the invention provides a nozzle abnormity compensation method and device, an inkjet printing device and a storage medium. The method includes the steps that a first printing parameter is acquired, feathering processing is performed on first printing data corresponding to the first printing parameter, and second printing data are obtained; according to abnormal nozzle position information and the first printing parameter, first data corresponding to an abnormal nozzle are acquired from the second printing data, and compensation nozzle position information corresponding to compensation of the first data in a sprayer is determined; according to the compensation nozzle position information and the first printing parameter, corresponding second data during normal printing of acompensation nozzle are acquired from the second printing data, and the second data comprise ink outflow data and ink non-outflow data; and an address of the ink non-outflow data in the second data is determined, the first data are written into the address of the ink non-outflow data in the second data, and compensation data are generated. Due to the technical scheme, the problem that because ofabnormal ink outflow of the abnormal nozzle, the image quality becomes poor is solved, and the sprayer maintaining cost is reduced.
Description
technical field [0001] The invention relates to the technical field of inkjet printing, in particular to a nozzle abnormal compensation method, device, inkjet printing equipment and storage medium. 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 area A (or...
