    • PURPOSE: An ink eruption characteristic control method and driving method of the ink-jet printing apparatus are provided to be applied to the various fields of minute structure generating processes including the organic thin film transistor field etc, flexible display field, the metal wiring, including, the printing electronics field including the flat board display field, the electronic paper etc. CONSTITUTION: The ink eruption characteristic control method and driving method of the ink-jet printing apparatus includes: controlling at least one of voltage and approval duration of the driving signal on each of a plurality of piezoelectric actuators(130) which offers the discharge pressure to a plurality of nozzles so that the volume of a plurality of ink droplets discharged from a plurality of nozzles(128) be similar. A plurality of ink droplets discharged from a plurality of nozzles are at the same time arrived to the print media. The authorization start timing of the driving signal is displaced about a plurality of piezoelectric actuators. The same first driving signal of waveform is sanctioned at the same time in a plurality of piezoelectric actuators and a plurality of ink droplets is discharged. When the base time to be corresponded to the home location is expired, the volume of a plurality of ink droplet of the discharged are detected. The value in which the detected volume becomes similar to a plurality of piezoelectric actuators. The second driving signal is determined by controlling at least one of voltage and approval duration of the first driving signal.
    • 目的:提供喷墨打印设备的喷墨特性控制方法和驱动方法,用于包括有机薄膜晶体管领域等的微小结构生成处理的各个领域,柔性显示领域,金属布线,包括 ,包括平板显示领域,电子纸等的印刷电子领域。构成:喷墨打印设备的喷墨特性控制方法和驱动方法包括:控制驱动信号的电压和批准持续时间中的至少一个 在对多个喷嘴提供排出压力的多个压电致动器(130)中的每一个上,使得从多个喷嘴(128)排出的多个墨滴的体积相似。 从多个喷嘴排出的多个墨滴同时到达打印介质。 驱动信号的授权开始定时围绕多个压电致动器移位。 在多个压电致动器中同时对同一波形的第一驱动信号进行同时处理,并且排出多个墨滴。 当与原始位置相对应的基准时间期满时,检测出排出的多个墨滴的体积。 检测到的体积变得类似于多个压电致动器的值。 通过控制第一驱动信号的电压和许可持续时间中的至少一个来确定第二驱动信号。
