目的 研究利用凹版胶印方式印制电子产品必须满足的相关条件。 方法 从网形状的角度探究对“锯齿”边缘的影响， 采用模拟分析的方法研究接触角对油墨转移的影响。 结果 100%的油墨从网穴转移到橡皮布上必须满足cosθ 像＞ 1+cosθ 版。 如果采取圆形网点、椭圆形网点等其他形状的网点，无论在何种印刷压力下都会产生“锯齿”边缘；采用方形网点， 在适当的印刷压力下可以降低甚至消除“锯齿”边缘。 结论 上板接触角与油墨的转移率呈负相关关系,下板接触角与油墨转移率呈正相关关系。 印刷电子产品应当采用方形网点。

Objective To study the conditions to be satisfied when printing electronic products using gravure-offset．Methods The effects of dot shape on the saw-teeth edge were studied, and the effects of contact angle on the transferredvolume and rate of ink were analyzed by simulation. Results The surface energy must meet cosθ 像＞ 1+cosθ 版 so that theink could be 100% transferred from the gravure plate to the blanket. If other dot shapes like round dot or oval dot were used,then saw-teeth edge occurred regardless of the printing pressure. However, using square dots could decrease or eveneliminate the saw-teeth edge under appropriate printing pressure. Conclusion When the upper contact angle had a negative correlation with the ink transfer rate, and the lower contact angle had a positive correlation with the ink transfer rate, square dot should be used in printing of electronic products.
