目的 制备环保油墨并研究该环保油墨在不同承印材料上的褪色效果。方法 以蒸馏水为溶剂，超细指示剂染料为呈色物质，自制乳液为连接料，加入多种助剂制得环保油墨，研究该环保油墨在不同承印材料上的褪色效果。结果 该环保油墨在不同的承印材料上采用丝网印刷工艺进行印刷，墨迹一段时间后能完全褪色。结论 使用该环保油墨印刷有利于承印物的重复使用。

The work aims to make environmental ink and research the fading effect of environmental ink on different printing materials. Environmental ink was prepared with distilled water as solvent, ultrafine grinding good indicator pigment as color material and home-made emulsion as connection material, and various additives were added. Fading effect of environmental ink on printing materials was studied. Environmental ink printed on printing material by screen printing technology could completely fade after a while. In conclusion, the use of environmental ink is beneficial to the reuse of printing materials.
