摘要： Imaging apparatus and method adapted to control ink droplet volume and void formation. The apparatus (10) includes an ink jet print head (45) having a nozzle (110) for ejecting an ink droplet (150) therefrom. A heater element (130) is in heat transfer communication with the ink droplet for variably supplying heat energy to the ink droplet, so that the volume of the ink droplet is controlled as the heat energy is variably supplied to the ink droplet. A controller (40) is connected to the heater element for variably controlling the heat energy supplied to the ink droplet. The controller variably controls the heat energy by variably controlling a plurality of voltage pulses sequentially supplied to the heater element. Moreover, in order to reduce the potential for void formation in the ink droplet, the pulses are spaced-apart by a predetermined delay interval. Suitable control of ink droplet volume and delay interval between pulses results in uniform print density and "gray-scaling" of each dot or pixel in the output image and also precludes void formation.

摘要翻译：成像装置和方法angepasst控制墨滴体积和空隙形成。的装置（10）包括在喷嘴的喷墨打印头（45）具有（110），用于从喷射液滴（150）的墨水存在。的加热器元件（130）与所述墨滴热能可变地供给到墨滴传热连通，所以没有作为热能被可变地提供到墨滴的墨滴的体积被控制。控制器（40）被连接至加热器元件，用于可变地控制供给到墨滴的热能。控制器可变地通过可变地控制顺序地提供给加热元件的电压脉冲的复杂控制的热能。更完了，为了减少在墨滴形成空隙的可能性，脉冲由一预定延迟间隔间隔开的。墨滴体积和均匀的印刷密度和输出图像中的每个点或像素的“灰色缩放”脉冲结果之间的延迟间隔的适当的控制，从而排除了空隙的形成。
