溫變油墨 溫變油墨和熱敏油墨、感溫變色油墨、遇熱變色油墨、溫度變色油墨 溫變油墨、熱敏油墨和感溫變色油墨 溫變油墨是一種能隨溫度變化而發(fā)生顏色變化的油墨,分為可逆消色、可逆顯色、可逆變色,記憶型、區(qū)間顯色、不可逆顯色、不可逆變色七大系列。
·可逆溫變消色:溫變油墨經(jīng)加溫后顏色退去變成無色,冷卻后立即恢復(fù)到原有顏色; ·可逆溫變顯色:在常溫下顯示無色,經(jīng)加溫后變成另一種顏色,冷卻后又恢復(fù)原來的無色; ·可逆溫變轉(zhuǎn)色:油墨在常溫下顯示顏色,加溫后變成另一種顏色,冷卻后復(fù)原; ·不可逆溫變油墨:加溫后從無色或從某種特定顏色轉(zhuǎn)變成另外一種顏色,冷卻后其顏色也不再消失。 注:可逆溫變消色系列 顏色 | 印刷方式 | 溫度 | 紅色系列 | 金紅、大紅、玫紅 | 絲印、凹印 柔版、膠印 | 5℃-50℃
常用: 31℃-33℃、50℃ | 綠色系列 | 草綠、中綠、墨綠、孔雀綠 | 藍(lán)色系列 | 天藍(lán)、寶藍(lán)、深藍(lán) | 其它色系 | 土黃 | 黑 | 其它顏色可訂做 |
注:可逆溫變顯色系列 注:不可逆溫變顯色系列 顏色 | 印刷方式 | 溫度 | 黑 | 水性絲印 | 65℃、80℃、95℃、110℃、120℃、135℃ | 藍(lán) | 紅 |
目前市場(chǎng)上的遇熱會(huì)變色的杯子乃溫變油墨一大杰作! | |
注意事項(xiàng) | 1、可逆型可做水性和油性絲印油墨及部分顏色可做膠印柔版;不可逆型只能做水性絲印油墨。
2、所有絲印類型油墨建議用200目絲網(wǎng)印刷;
3、膠印溫變油墨一般不用添加助劑,如太稠可加膠印調(diào)墨油,要提高干燥速度可添加0.5-1%的紅燥油和白燥油;絲印按干燥要求使用719快干、783慢干等溶劑;凹印用丁酯、乙酯、異丙醇、二甲苯等溶劑;水性絲印溫變油墨以水作為溶劑。 |
(1). Irreversible temperature sensitive ink Irreversible temperature sensitive ink includes coloration ink and discoloration ink. Irreversible coloration temperature sensitive ink is colorless in appearance but shows colors after being heated and can’t restore colorless once again after cooling off. The original color of Irreversible discoloration temperature sensitive ink can be changed into another one and it can’t restore its original colors after being cooled once again.
(2). Reversible temperature sensitive inkReversible temperature sensitive ink includes three kinds: coloration, fading and discoloration ones. Reversible coloration temperature sensitive ink is colorless in appearance but shows colors after being heated and can restore colorless after being cooled. The original color of reversible fading temperature sensitive ink disappears after being heated and it can restore its original color after being cooled. The original color of reversible discoloration temperature sensitive ink can be changed into another one and it can restore its original color after being cooled. | |
