糊版(ban)(ban)(ban)和(he)燙(tang)印(yin)后(hou)電(dian)化(hua)(hua)鋁(lv)變色糊版(ban)(ban)(ban)主要是(shi)由于(yu)燙(tang)金版(ban)(ban)(ban)制(zhi)作(zuo)不良，電(dian)化(hua)(hua)鋁(lv)安裝(zhuang)得松弛(chi)或電(dian)化(hua)(hua)鋁(lv)走(zou)箔不正(zheng)確造(zao)成的(de)。燙(tang)印(yin)后(hou)電(dian)化(hua)(hua)鋁(lv)變色主要是(shi)燙(tang)印(yin)溫度過高造(zao)成的(de)。另外(wai)，電(dian)化(hua)(hua)鋁(lv)起皺也易造(zao)成燙(tang)印(yin)疊色不勻(yun)而變色，可(ke)通過適當(dang)降低溫度加以(yi)解決(jue)。對于(yu)圓壓平(ping)機(ji)型可(ke)在送箔處加裝(zhuang)風扇(shan)，保持拉箔飄(piao)挺，避免在燙(tang)印(yin)前電(dian)化(hua)(hua)鋁(lv)觸及燙(tang)金版(ban)(ban)(ban)而烤焦(jiao)。
