Abstract:
An inkjet recording method is performed using an inkjet recording device including a recording head provided with a nozzle, a pressure chamber, a pressure generator and a driving signal generator, the method satisfying the following requirements (1) and (2): (1) it is required to use aqueous ink having a dynamic surface tension larger by 10 mN/m or more than a static surface tension when the surface life measured at 25° C. by a maximum foaming pressure method is 15 ms and a dynamic surface tension larger by 5 mN/m or more than a static surface tension when the surface life measured by a maximum foaming pressure method is 1500 ms and (2) it is required that the signals have a drawing pulse in one print period and a meniscus of the aqueous ink is drawn into the nozzle in two stages by the drawing pulse.
