ABSTRACT:
A line head inkjet printer includes an inkjet head, a controller and a storage unit. The controller generates n kinds of waveforms used to eject different amounts of ink from the nozzles (3≦n (natural number)). The storage unit stores a combination of m kinds of waveforms selected from the n kinds of waveforms, for each block including at least one nozzle (2≦m (natural number)≦n−1). When the printer conducts gradation printing with using m kinds of waveforms selected from the n kinds of waveforms, a difference among the blocks in an amount of ejected ink per nozzle in a case of using the stored combinations of m kinds of waveforms for the respective blocks is smaller than that in a case of using one and the same combination of m kinds of waveforms for all the blocks.
