用特殊的热转印油墨把各种图案印刷在特殊的一种纸上面，然后通过温度和压力将图案再转移到产品上。这种特殊的在热转印工艺中的纸张就叫做热转印纸:

热转印是指将中间载体薄膜上的图文采用相应的压力转移到承接物上的一种印刷方法，所以可翻译为：Heat Transfer Printing Paper is a necessity used as an interfacial layer in hot extension technology.Using particular Heat Transfer Printing Ink ,pinter prints various patterns on its surface in advance and the patterns finally will be transferred and infiltrated to other media under required temperature and pressure.

好吧。。。希望有人来帮你翻译那么专业的说法。。。不过就算无语法错误，不是这个行业的人也不一定懂你要表达的意思。

弱弱的理解一下，那个Polyester Film是不是就是幻灯片啊？
