Recently, inkjet systems have been used in the field of commercial printing thanks to print-on-demand. To disseminate the IJ widely in the commercial printing field, high speed printing for high productivity would be required. In high speed printing, high jetting performance is needed. Good jetting performance means that a jetted droplet forms a spherical droplet before it reaches the paper surface. From the hypothesis that jetting performance depends on dynamic surface tension in a time scale of micro second order, the relationship between jetting performance and dynamic surface tension was investigated using the ink including pigment, humectant and surfactant. To check the jetting performance, the ink jetting behavior was investigated using a commercial line type print head at high jetting frequency. Dynamic surface tension in micro second order was measured by the Continuous Ink Jet system. The higher dynamic surface tension in the short time range was found to show better jetting performance with its single droplet formation. It was concluded that good jetting performance could be achieved by adjusting the ink composition to control dynamic surface tension.
