燙(tang)金(jin)基本工藝是在壓力(li)(li)狀態，即電(dian)(dian)化(hua)鋁(lv)被(bei)燙(tang)印版(ban)、承(cheng)(cheng)印物(wu)(wu)壓住的狀態下(xia)，電(dian)(dian)化(hua)鋁(lv)受熱(re)使其上(shang)(shang)熱(re)熔(rong)(rong)(rong)(rong)性的有(you)機硅樹(shu)脂(zhi)層和膠牯劑(ji)熔(rong)(rong)(rong)(rong)化(hua)，此時受熱(re)熔(rong)(rong)(rong)(rong)化(hua)的有(you)機硅樹(shu)脂(zhi)粘(zhan)性變(bian)小(xiao)，而特(te)種(zhong)熱(re)敏膠粘(zhan)劑(ji)受熱(re)熔(rong)(rong)(rong)(rong)化(hua)后(hou)粘(zhan)性增加(jia)，使得鋁(lv)層與電(dian)(dian)化(hua)鋁(lv)基膜剝離的同(tong)時轉印到了承(cheng)(cheng)印物(wu)(wu)上(shang)(shang)。隨著壓力(li)(li)的卸除，膠粘(zhan)劑(ji)迅速冷卻固(gu)化(hua)，鋁(lv)層牢(lao)固(gu)地附著在承(cheng)(cheng)印物(wu)(wu)上(shang)(shang)，完(wan)成(cheng)一個燙(tang)印過程。
