燙(tang)金基本工藝是在壓(ya)力狀(zhuang)態，即電化(hua)(hua)鋁被(bei)燙(tang)印版、承(cheng)(cheng)印物(wu)(wu)(wu)壓(ya)住的(de)狀(zhuang)態下，電化(hua)(hua)鋁受(shou)熱(re)(re)使(shi)其(qi)上(shang)熱(re)(re)熔(rong)(rong)性(xing)的(de)有機硅樹脂層和膠牯劑熔(rong)(rong)化(hua)(hua)，此時(shi)受(shou)熱(re)(re)熔(rong)(rong)化(hua)(hua)的(de)有機硅樹脂粘(zhan)性(xing)變小，而(er)特(te)種熱(re)(re)敏膠粘(zhan)劑受(shou)熱(re)(re)熔(rong)(rong)化(hua)(hua)后粘(zhan)性(xing)增加，使(shi)得鋁層與(yu)電化(hua)(hua)鋁基膜剝離的(de)同(tong)時(shi)轉印到了承(cheng)(cheng)印物(wu)(wu)(wu)上(shang)。隨著(zhu)壓(ya)力的(de)卸除(chu)，膠粘(zhan)劑迅速冷卻固化(hua)(hua)，鋁層牢(lao)固地附著(zhu)在承(cheng)(cheng)印物(wu)(wu)(wu)上(shang)，完成一個燙(tang)印過程。
