【摘要】 本文制备了可逆温致变色胶印油墨,并通过印刷适性仪等实验设备,改变印刷压力、叠印方式等参数,探讨了可逆温致变色油墨的印刷适性,利用分光光度计等设备测定了可逆温致变色油墨在胶版印刷方式下,L、a、b值、色差以及印刷油墨的防伪变色性能。最后通过实验得到可逆温致变色油墨最佳制备方案,达到最优印刷防伪性能。更多还原

【Abstract】 By experimentment equipment like printability tester,this paper prepared the reversible thermochromism material in offset printing ink,changed parameters like printing pressure and overprint patterns.Then,it discussed the printability of reversible thermochromism off-set printing ink;and by spector photometer,measured the L a b value,chromatism,and anti-counterfeiting properties of off-set printing ink of reversible thermochromism ink under off-set printing pattern.Finally,using test,it obtained the best preparation program of reversible themochromism off-set printing ink,reached the goal of optimal anti-counterfeit printing properties.更多还原
