在分析影响导电油墨电阻值因素的基础上,设计了丝网印刷工艺,在不同承印物上印刷了导电油墨条码,经过测量承印物上充分干燥后的导电油墨条码的电阻值,对电阻值数据进行了分析和处理,探讨了使用导电油墨电阻值防伪的可行性。结果表明，不同网目线数的网版印刷的导电油墨条码的电阻值也不同，所以用导电油墨印制条形码，使条形码增加了一项电阻防伪功能。

Influencing factors on electric resistance of electrically conductive ink were analyzed. A screen printing process was designed and bar codes were printed on different substrates using electrically conductive ink. The prints were dried and the electric resistance of bar codes of electrically conductive ink was tested, processed and analyzed. The results showed that the bar code resistances of electrically conductive ink change with different screen lines, therefore, bar code printed by electrically conductive ink can be another effective way for package anti-counterfeit printing.
