摘　　要：印刷油墨的粘性对提高印刷质量和效率有重要影响,本文阐述了雷德式油墨粘性测量系统的结构与组成,采用高精度力传感器有效解决了粘性测量问题,精度可达到0.01N,分析了油墨流变学特性与粘性测量系统的动力学过程,得到了油墨粘性值的实用估算公式并通过实验验证。结果表明:油墨粘性值与转速成线性,与温度成指数关系。研究结果为油墨的生产和使用提供了理论与实验依据。Ink tack has important influence on improving printing quality and efficiency. The paper presents the structure and composition of Reed Inkometer. A high precision force sensor has been used to detect tack-force. The result has a precision of 0.01 N. It analyses the rheological characteristics of ink and dynamic process of tack-measurement system, a practical formula for ink tack estimating has been obtained and verified by experiment. Practical test shows that ink tack bears a linear relationship to roller speed, and has an exponential relationship with temperature. The research result provides theoretical and experimental basis for ink production and use.
