燙金(jin)基本(ben)工藝是在壓(ya)力(li)狀態，即電化(hua)鋁(lv)被(bei)燙印版、承印物壓(ya)住的(de)狀態下，電化(hua)鋁(lv)受熱(re)(re)(re)使其上(shang)熱(re)(re)(re)熔(rong)(rong)(rong)性的(de)有機(ji)硅樹(shu)脂層(ceng)(ceng)和膠牯劑熔(rong)(rong)(rong)化(hua)，此時(shi)受熱(re)(re)(re)熔(rong)(rong)(rong)化(hua)的(de)有機(ji)硅樹(shu)脂粘(zhan)性變小(xiao)，而(er)特(te)種(zhong)熱(re)(re)(re)敏膠粘(zhan)劑受熱(re)(re)(re)熔(rong)(rong)(rong)化(hua)后粘(zhan)性增加，使得鋁(lv)層(ceng)(ceng)與電化(hua)鋁(lv)基膜剝(bo)離(li)的(de)同(tong)時(shi)轉(zhuan)印到了承印物上(shang)。隨(sui)著壓(ya)力(li)的(de)卸除，膠粘(zhan)劑迅速冷卻固化(hua)，鋁(lv)層(ceng)(ceng)牢固地附(fu)著在承印物上(shang)，完成一個燙印過程(cheng)。
