结合喷墨印刷原理分析了影响RFID标签识别性能的因素，进而研究了叠印率及底基温度对RFID标签天线识别性能的影响。实验证明:随着叠印率的增大，导体的连续性增强，墨层增厚，线宽变大，标签识别性能也得以提高，而且提高操作温度对导体连续性起着正作用，表面更为光滑，线宽先增大后减小。

Influencing factors of RFID tag's identification performance were analyzed with inkjet principles. The influence of trapping rate and substrate temperature on RFID tag's identification performance was studied. Experiments showed that with increase of trapping rate, the continuity of the conductor is improved, the line thickness and width become larger, and the identification performance is also improved; as temperature increases, the continuity of conductor is also enhanced, the surface is more smooth, and the line width first increases and then decreases.
