EP0245002A2 Ink jet printing 失效

摘要： A continuous-stream ink jet printhead (10) is disclosed utilizing constant thermal pulses to perturb the ink streams (11) emitted through a plurality of nozzles (27) to break up the ink streams into droplets at a fixed distance from the nozzles whereat the drops are individually charged by a charging electrode in accordance with digitized data signals. Each printhead has a manifold, a plurality of ink channels (22) communicating at one end with the manifold and terminating at the other end with nozzles, and at least one resistor addressed by a predetermined frequency of current pulses for applying thermal pulses to the ink. In one embodiment, a resistor is positioned in each of the channels adjacent the nozzles, and in another embodiment, a single resistor is located in the ink manifold. The resistors are pulsed at low power to generate a perturbation of ink properties such as density, viscosity, or surface tension, without producing a phase change in the ink.
摘要翻译：公开了一种连续流喷墨打印头（10），其使用恒定的热脉冲来扰乱通过多个喷嘴（27）发射的墨水流（11），以将油墨流分散成与喷嘴固定距离的液滴根据数字化数据信号，通过充电电极单独地充电滴。每个打印头具有歧管，多个墨水通道（22）在一端与歧管连通并且在另一端处连接有喷嘴，并且至少一个电阻器由预定频率的电流脉冲寻址，以将热脉冲施加到墨水。在一个实施例中，电阻器位于与喷嘴相邻的每个通道中，并且在另一个实施例中，单个电阻器位于墨水歧管中。电阻器以低功率脉冲以产生油墨性质（例如密度，粘度或表面张力）的扰动，而不会导致油墨中的相变。
