燙(tang)金(jin)基本工藝是在壓力狀態(tai)，即電(dian)化鋁被燙(tang)印版、承(cheng)(cheng)印物壓住(zhu)的(de)(de)(de)狀態(tai)下，電(dian)化鋁受(shou)熱使其上(shang)熱熔(rong)性(xing)的(de)(de)(de)有機硅樹(shu)脂(zhi)(zhi)層(ceng)(ceng)和膠牯劑熔(rong)化，此時(shi)(shi)受(shou)熱熔(rong)化的(de)(de)(de)有機硅樹(shu)脂(zhi)(zhi)粘(zhan)(zhan)性(xing)變小，而特種熱敏(min)膠粘(zhan)(zhan)劑受(shou)熱熔(rong)化后(hou)粘(zhan)(zhan)性(xing)增加，使得鋁層(ceng)(ceng)與電(dian)化鋁基膜剝(bo)離的(de)(de)(de)同時(shi)(shi)轉(zhuan)印到了承(cheng)(cheng)印物上(shang)。隨著壓力的(de)(de)(de)卸除(chu)，膠粘(zhan)(zhan)劑迅速(su)冷卻固化，鋁層(ceng)(ceng)牢固地附著在承(cheng)(cheng)印物上(shang)，完(wan)成(cheng)一個燙(tang)印過程。
