摘要： A method and an apparatus for executing the method are disclosed, wherein, based upon the analysis of print data for a printing element of an inkjet printhead, the printing element is not driven if zero-pixels are detected, corresponding with print not requiring the printing element to eject an ink drop. Successive occurrences of such events provide a continuous period of inactivity for the printing element, i.e. a period of rest allowing the ink in the printing element and the printing element itself to recover from the excitations enforced by preceding drop ejection processes. Periods of inactivity of a printing element are interrupted at regular time intervals by driving the printing element's actuator with a precursor signal to prevent latency problems associated with inactive printing elements.
摘要翻译：公开了一种用于执行该方法的方法和装置，其中，基于对喷墨打印头的打印元件的打印数据的分析，如果检测到零像素，则不驱动打印元件，对应于不需要打印的打印元素以喷射墨滴。这种事件的连续发生为打印元件提供连续不活动的时间段，即，允许打印元件中的墨水和打印元件本身从通过先前的液滴喷射过程强化的激发恢复的休止期。通过用前驱信号驱动打印元件的致动器，以规则的时间间隔中断打印元件的不活动时间段，以防止与非活动打印元件相关联的延迟问题。

摘要： An ink supply system for an industrial ink jet printer is provided making use of a least one buffer vessel (8) wherein ink at low pressure is isolated and pressurized to a high pressure suited for feeding the ink to the printhead (1). A recirculation ink supply system using plural buffer vessels is suited for repressurizing the ink without the use of a pump. The system avoids generation of gas bubbles due to cavitation which are present in systems using a pump for repressurizing ink.
