<P>PROBLEM TO BE SOLVED: To efficiently and properly perform density adjustment that reduces a density difference between heads. <P>SOLUTION: An adjusting drop number setting part 335 establishes an adjusting drop number (liquid droplet number) in which density change of an image takes place notably when a droplet amount of ink per one liquid droplet is changed according to each of types of a print medium (printing paper) input from an operation panel 340, or establishes uniformly not relating to a type of a print medium. When density difference which needs adjusting is accepted by viewing between images by two adjacent ink heads on a density measuring chart which a chart printing execution section 333c has made to print, an ink droplet amount per one liquid drop of an established adjusting drop number is adjusted by adjusting of driving voltage of an ink head of a head unit 110 responding to input from an operation panel 340. <P>COPYRIGHT: (C)2012,JPO&INPIT |
