Abstract:
1. A method of controlling the driving of a function liquid droplet ejection head having a plurality of nozzle arrays disposed therein with a different function liquid droplet ejection amount per unit nozzle, wherein, in one print cycle, driving of the plurality of nozzle arrays is controlled by using a single driving signal inclusive of: wherein the micro oscillation pulse is inputted before the first and second ejection pulses are inputted in said one print cycle, and the damping pulse is inputted after the first and second ejection pulses are inputted in said one print cycle, and wherein the first nozzle array ejects a first function liquid droplet ejection amount and the second nozzle array ejects a second function liquid droplet ejection amount which is smaller than the first function liquid droplet ejection amount.
