The invention provides a multi-spray-head nozzle abnormal compensating method, device, equipment and a storage medium. The method comprises the steps that according to printing parameters, the overlapping nozzle area is obtained, first printing data corresponding to the overlapping nozzle area are subject to feathering to obtain second printing data; abnormal nozzle position information of the overlapping nozzle area is obtained, according to the abnormal nozzle position information, first data corresponding to abnormal nozzles are obtained from the second printing data, and compensation nozzle position information of the first data is obtained from the overlapping nozzle area; according to the compensation nozzle position information, second data corresponding to compensation nozzles areobtained from the second printing data, and the second data comprise ink output data and non ink output data; the address of the non ink output data in the second data is determined, and the first printing data are corresponding written in the address of the non ink output data to generate compensation data. According to the technical scheme, the problem that the abnormal nozzles output ink abnormally, and the image quality is poor is solved, and the spraying head maintaining cost is reduced.
Description
technical field [0001] The invention relates to the technical field of inkjet printing, in particular to a multi-head nozzle abnormality compensation method, device, 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. Multi-nozzle scanning printing technology is a high-speed printing technology in the field of inkjet printing at present. Multi-nozzle scanning printing technology is to connect multiple nozzles end to end to form a nozzle group, which can cover the entire image to be printed. Scanning and printing can be completed with fast speed and high efficiency, such as figure 1 It is a schematic diagram of the nozzle installation of a multi-nozzle scanning printer. The inkjet printer has a nozzle group Q with several nozzles, namely the first nozzle, the second nozzle...the X nozzle, and the moving direction of the printing medium ...
