<P>PROBLEM TO BE SOLVED: To provide an ink composition high in jet stability and giving high-quality printed images when used in an inkjet printing method, to provide a printing method using the ink composition, to provide printed images obtained using the ink composition, and to provide an ink set and an ink head. <P>SOLUTION: The ink composition 60 is produced in such a way that the difference between dynamic surface tension(mN/m) and static surface tension(mN/m) determined at 24-26°C by maximum foam pressure method is 0-7(mN/m). The printing method comprises the following process. The ink composition 60 is reserved in the ink tank 50 of the ink head 1 and fed from the ink tank 50 into an ink chamber 40 with a jet nozzle 31, voltage is applied on a diaphragm section 12 formed of a piezoelectric material and pressure is applied on the ink composition 60 filled in the ink chamber 40 through the diaphragm section 12 to jet droplets of the ink composition 60 via the jet nozzle 31, and the droplets are put on a printing material to print images on the printing material. <P>COPYRIGHT: (C)2004,JPO |
