Abstract
A compensation method includes determining position information of an abnormal nozzle of an inkjet head; acquiring printing parameters, determining first data corresponding to the abnormal nozzle, and based on the position information of the abnormal nozzle and the printing parameters, determining position information of a compensation nozzle for compensating the first data corresponding to the abnormal nozzle; and based on the printing parameters, acquiring second data of the compensation nozzle in a normal printing state which includes ink out data and ink holding data, determining an address of the ink holding data, and generating compensation data by writing the first data into the address of the ink holding data. A compensation device includes: an abnormal nozzle position determination module; a compensation nozzle position determination module; and a compensation data generation module. An inkjet printer includes: a controlling unit, an inkjet head unit, and a nozzle compensation unit.
