喷墨控制参数对UV喷墨油墨墨滴状态的影响

Influence of Nozzle Control Parameters on the Drop State of UV-curable Ink-jet Ink

喷墨油墨墨滴状态是影响喷墨成像质量的重要因素,喷墨设备控制参数的设定对最终墨滴状态的影响较大。为满足喷墨印刷质量的要求,配制适用于XAAR喷头的UV喷墨油墨,控制喷头分别在不同电压和点火频率下对油墨进行喷射,观测和分析不同条件下油墨的墨滴状态。结果表明,UV喷墨油墨在驱动喷头的不同工作电压和点火频率下,所喷射的油墨的墨滴速度、墨滴拖尾长度和墨滴体积、圆度均存在较大差异,喷头的控制参数与油墨的墨滴状态存在一定关系。

The drop state of the ink-jet ink is an important factor that influences the ink-jet imaging quality, nozzle characteristics and parameters have a great influence on the final drop state. In order to meet the requirement of printing quality, we prepare UV ink-jet ink appropriate for XAAR, control the nozzle under different voltage and ignition frequency, observe and analyze the drop state under different ink-jet condition . The result shows that it＇s existed a large differences of the drop state including drop speed, drop volume and drop tail length when the UV ink-jet inks have different voltage and ignition frequency, there is a certain relationship between control parameters of the nozzle and the ink＇s drops state.
