ABSTRACT:
A testing method includes sorting inkjet heads into a plurality of groups on the basis of known information about ink flow, preparing basic driving waveform data corresponding to each of the groups and modification data that partially modifies the basic driving waveform data to individually store them in advance in a storing section, creating individual waveform information that instructs combinations of the basic driving waveform data with the modification data with respect to an inkjet head to be tested to apply a modified driving waveform, and repeating the modification of the individual waveform information until a recording state becomes good.
