Inkjet printing method, device, equipment and storage medium for overlapping area of nozzle group Technical Field The present invention relates to the field of inkjet printing technologies, and in particular, to a method, an apparatus, a device, and a storage medium for inkjet printing in an overlapping area of a nozzle set. Background Inkjet printing technology refers to technology in which ink droplets are ejected through a head onto a printing medium to obtain an image or text. Because the height of the nozzle is fixed, in order to improve the width of one-time scanning printing, a plurality of nozzles are often used to splice along the sub-scanning direction Y to obtain a nozzle group as shown in fig. 1, and the height of the nozzle group is the width of one-time scanning printing. However, when the nozzles are spliced, part of the nozzles are overlapped, and when the overlapped nozzles are used for printing, if all the ink is discharged, the ink quantity concentration of the printed image corresponding to the spliced position is deepened, the printing effect of the whole image is affected, and therefore the printing data corresponding to the spliced channel is subjected to eclosion treatment and then is subjected to ink-jet printing. However, in some practical production, in order to effectively utilize the nozzles, the number of overlapping holes between the nozzles is small when the nozzles are spliced, so that even if the nozzles are subjected to feathering, the corresponding printing effect of the spliced channel is not good enough, and the nozzles are limited to be cured on the bottom plate, so that the nozzles cannot be moved to change the size of the spliced region so as to increase the number of the overlapping holes to improve the printing effect of the spliced channel of the nozzles, and how to improve the image printing quality of the spliced channel on the basis of not moving the nozzles is needed to be solved.
