This article describes a series of modern developments carried out by the inkjet community in its quest to improve material compatibility, printing quality, and reliability. Recent progresses in rheology have advanced our understanding of liquids at the time scales that are characteristic of inkjet printing processes. As a result, microsecond rheology now permits the formulation of inks with tailored viscosities that vary according to the time-scale of their dynamics, i.e. low effective viscosity during jetting but high at break up and landing. These advances have permitted the community to assess, and often predict, the ink jetting behaviour, at a given printing frequency, based on the linear or non-linear viscoelasticity and other fluid characteristics. Advances in fluidic systems and in waveform design have now enabled the printing of high viscous inks that were previously impossible to jet on demand. This capability is opening up new markets and opportunities for inkjet, from the printing of glues to the use of heavily loaded ceramic inks. Advances in printhead design, and the assessment of printing patterns using common standards, now allow the verifiable and reliable operation of industrial-scale digital inkjet printing in a wide range of environments. Recent improvements on printhead cleaning protocols, have contributed to an increase in printing speed and operating time by reducing the production of mist and satellite droplets neighbouring the printhead region. Thanks to these improvements, inkjet is displacing traditional technologies, such as offset and screen printing, in large markets including graphics, packaging and labelling.

喷墨打印的配方，质量，清洁和其他进步

本文介绍了喷墨社区为提高材料兼容性，打印质量和可靠性而进行的一系列现代开发。流变学的最新进展使我们对喷墨打印过程所特有的时间尺度上的液体有了更深入的了解。结果，微秒流变学现在允许配制具有定制粘度的油墨，该粘度根据其动力学的时间尺度而变化，即在喷射过程中的有效粘度较低，但在分解和着陆时较高。这些进步使社区能够根据线性或非线性粘弹性和其他流体特性，在给定的印刷频率下评估并经常预测喷墨行为。流体系统和波形设计方面的进步现已使以前无法按需喷射的高粘度油墨得以印刷。从胶水的印刷到重载陶瓷油墨的使用，这种能力为喷墨技术打开了新的市场和机会。打印头设计的进步以及使用通用标准对打印图案的评估，现在使工业规模的数字喷墨打印可以在各种环境中进行可验证且可靠的操作。打印头清洁方案的最新改进通过减少打印头区域附近的雾气和卫星液滴的产生，有助于提高打印速度和操作时间。由于这些改进，喷墨技术正在取代传统技术，例如胶印和丝网印刷，
