<P>PROBLEM TO BE SOLVED: To provide a technique for obscuring uneven density to be visually confirmed, even when the number of used nozzles is reduced. <P>SOLUTION: An inkjet printing apparatus includes a printhead including a temperature sensor and a plurality of heat generation elements each of which generates a thermal energy required to discharge an ink in response to application of a driving pulse, and the inkjet printing apparatus performs printing by causing the printhead to relatively scan a recording medium. The inkjet printing apparatus further includes: a storage unit configured to store a plurality of driving pulse tables required to define a plurality of driving pulses; a specifying unit configured to specify the number of the heat generation elements used in printing out of the plurality of heat generation elements; and a control unit configured to perform control so as to select any of the plurality of driving pulse tables based on the number of the heat generation elements specified by the specifying unit and so as to select a driving pulse to be applied to the plurality of the heat generation elements from the selected driving pulse table based on the temperature of the printhead measured by the temperature sensor. <P>COPYRIGHT: (C)2013,JPO&INPIT |
