为使印刷在PET上的紫外一热成型丝网印刷油墨有较好的附着效果，研究了油墨配方的改变、颜料种类改变及颜料颗粒大小改变对墨膜在PET表面的柔韧性和附着力的影响。实验结果表明，油墨中PUA含量的改变、颜料种类的不同及颜料颗粒大小对墨膜的柔韧性和附着力均有一定影响。当PUA含量为36％时，油墨柔韧性和附着力均达到最佳，柔韧性为1．0mm，附着力为97％；颜料颗粒大小为25μm时，油墨柔韧性和附着力较好；同时发现不同种类的颜料也会对实验结果产生影响。

The experiment researches the changing of formulation of the UV screen printing ink for hot moulding, different kinds of colorant and the measurements of colorant grain influence flexibility and adherence of the ink. The result shows that when PUA contents increase to 36%, both of flexibility and adherence achieve the best, the record of flexibility is 1. Omm and the adherence is 97% ; flexibility and adherence of the ink are good when the measurements of colorant grain have reached 25μm. In the meantime,different kinds of colorant have different influences as the result.
