离型剂膜层的最佳厚度，可使转印油墨在转印过程中的附着力达到理想值。在室温（25 ℃）条件下，利用不同涂布压力和涂布速度，在PET塑料薄膜表面涂布了不同厚度及不同质量配比的离型剂，干燥后再涂布了转印油墨。针对不同实验条件下得到的涂布薄膜进行了剥离实验，结果表明：离型剂涂布速度为0.1 m/s，涂布压力为300 N，膜层厚度为9 μm，质量配比为3∶1时，转印油墨的剥离效果最理想。

The best thickness of release agent was researched in order to get ideal adhesion of transfer printing ink in the process of transfer printing. The surface of PET film was coated with release agent of different thickness and different mass ratio under 25 ℃, different pressures, and different spread speeds. The surface of release agent was coated with transfer printing ink after drying. Peeling experiments were carried out on the coated films. The results showed that ideal peeling effect can be achieved when coating speed 0.1 m/s, pressure 300 N, thickness 9 μm, and mass ratio 3∶1.
