Abstract: An inkjet printing correction method is used with an inkjet printing apparatus. The inkjet printing correction method includes the following steps. Firstly, a first test image file is printed out as a print test pattern by the inkjet printing apparatus. Then, the print test pattern is scanned to obtain a second test image file. Then, all second block intervals are compared with respective first block intervals, thereby obtaining correction interval difference data. According to the comparing results, a procedure of ejecting ink droplets from the ink nozzles is determined to be advanced or delayed.

Abstract: An inkjet head maintenance method is used in an inkjet printing apparatus, the inkjet printing apparatus includes a control unit, an inkjet head maintenance unit and at least one inkjet head. Firstly, the control unit reads inkjet head maintenance data from a predetermined inkjet head maintenance table. The inkjet head maintenance table includes the inkjet head maintenance data correlating with different printing modes. The inkjet head maintenance data include the number of maintenance times of the inkjet head during a predetermined printing period or a time interval between two adjacent maintenance times of the inkjet head. Next, the control unit issues an inkjet head maintenance command to the inkjet head maintenance unit according to the read inkjet head maintenance data. In response to the inkjet head maintenance command, the inkjet head maintenance unit is controlled to perform an inkjet head maintenance task corresponding to the inkjet head maintenance data.
