摘要
提出将环保型添加剂加入光变油墨中,通过复配实验得到适用于各种印刷方式的环保型光变油墨。调整环保型光变油墨的质量配比得到3种配方,再采用相关的检测手段和设备对3种配方油墨样品进行印刷适应性测试,主要包括油墨细度、黏度、干燥度、VOCs含量和印刷质量等测试。检测结果表明:3种配方油墨的细度均小于20μm,流出时间为18.5~30.0 s,干燥性能良好,VOCs含量低;丝网印刷、单张纸凹版印刷、卷筒纸轮转凹版印刷3种印刷方式下,3种配方墨样得到的印刷品干燥后,具有较佳的绿色变紫红色光变防伪效果,且印刷后的墨样无裂痕。通过优化后的光变油墨,各种印刷方式均表现出良好的印刷适应性及环保性。
The environmentally friendly additives were added into the optical variable ink,and the environmentally friendly printing ink suitable for various printing methods was made through compounding experiments.Three formulas were obtained by adjusting the quality ratio of the environmentally friendly optical variable ink.Then samples of the three kinds of ink were tested for printing adaptability by relevant means of detection and equipments,including ink fineness,viscosity,dryness,VOCs content and printing quality,etc..The detection results showed that the fineness of the three ink samples was less than 20 μm,the time was 18.5~30.0 s,with good drying performance and low VOCs content.With the printing methods of screen printing,sheet fed gravure printing,and web gravure printing,the dried prints using the three kinds of ink possessed good green purple red light anti-counterfeiting effect,with the printed ink sample crack-free.Through optimizing,the optical variable ink demonstrated a variety of printing adaptabilities and environmental protection performances.
