紅外激發(fā)油墨經(jīng)紅外光( 940 — 1060nm )激發(fā)而發(fā)出刺眼、鮮艷可見光的油墨稱為紅外激發(fā)油墨,顏色有紅、綠、蘭等。此油墨技術(shù)含量高,不易仿制,具有較高的防偽能力,適合在防偽印刷中廣泛應用?,F(xiàn)人民幣、汽油票使用該技術(shù)。適用于所有印刷方式,例如,膠印、凹印、絲印、柔版印刷、凸印等。1、 隱形無色熒光防偽油墨(UV and fluorescent security inks for invisible) 性能:紫外熒光油墨在紫外光(200-400nm)照射下,能發(fā)出可見(400-800nm)的油墨。通常指的短波紫外線激發(fā)可見熒光防偽印刷油墨,激發(fā)波長為254nm,長波紫外線激發(fā)可見熒光防偽印刷油墨,激發(fā)波長為365nm。這是一種技術(shù)成熟、使用方便的防偽油墨。適用于所有印刷方式,例如,膠印、凹印、絲印、柔版印刷、凸印等。膠印油墨包裝為標準一公斤鐵罐,凹印油墨包裝為5升或10升塑料桶。Description: UV and fluorescent security inks for invisible which are visible only under the right lighting(254nm or 365nm). The Inks are formulated for Silkscreen, Flexographic, Rotogravure, Intaglio, Letterpress and Offset printing press methods.2、 有色熒光防偽油墨(UV and fluorescent security inks for visible) 有色熒光防偽油墨在日光下顯示出油墨的本色,在驗鈔機或紫外光下可顯示出與油墨原有顏色一樣或者不一樣的鮮艷的熒光顏色,該油墨有不同的顏色可供用戶選擇。適用于所有印刷方式,例如,膠印、凹印、絲印、柔版印刷、凸印等。膠印油墨包裝為標準一公斤鐵罐,凹印油墨包裝為5升或10升塑料桶。Description: The security inks display light fluorescent color different from orangeal only under the right lighting(254nm or 365nm).UV and fluorescent security inks for visible which are visible only under the right lighting. The Inks are formulated for Silkscreen, Flexographic, Rotogravure, Intaglio, Letterpress and Offset printing press methods.3、 紅外防偽油墨(IR security inks for invisible or visible) 性能:紅外防偽油墨是在紅外光(780-980nm)激發(fā)下,能發(fā)出鮮艷黃綠色光的油墨。適用于所有印刷方式,例如,膠印、凹印、絲印、柔版印刷、凸印等。 膠印油墨包裝為標準一公斤鐵罐,凹印油墨包裝為5升或10升塑料桶。Description: IR security inks are visible only under the laser lighting(780-980nm).The Inks are formulated for Silkscreen, Flexo-graphic, Rotogravure, Intaglio, Letterpress and Offset printing press methods.4、 熱敏油墨(Thermo-chromic Inks) 熱敏油墨又稱熱變色油墨、溫變油墨。指在10-60℃攝氏度加熱作用下,能發(fā)生變色效果的油墨。熱致變色的原理是在加熱情況下使變色化合物發(fā)生物理構(gòu)象變化帶來自身的吸光性變化。 主要適用于凹印、絲印印刷方式,也可以膠印、柔版印刷、凸印等。膠印油墨包裝為標準一公斤鐵罐,凹印油墨包裝為5升或10升塑料桶。Description: Thermo-chromic Inks are respond to changes in temperature by changing from 'colored to colorless' or 'colored to colored' with a rise in temperature and from 'colorless to colored' when the printed image is exposed to a drop in temperature. The Inks are formulated for Silkscreen, Flexo-graphic, Rotogravure, Intaglio, Letterpress and Off-set printing press methods.5、 日光激發(fā)變色油墨(Sun-light sensitive security ink) 性能:日光激發(fā)變色油墨是在太陽光(也可在紫外光)照射下,能發(fā)出可見光400-800nm的防偽印刷油墨。這種油墨從應用來看是由于太陽光作用而變色,實質(zhì)上也是受紫外線照射而變色的。適用于所有印刷方式,例如,膠印、凹印、絲印、柔版印刷、凸印等。膠印油墨包裝為標準一公斤鐵罐,凹印油墨包裝為5升或10升塑料桶。Description: Sun-light sensitive security ink are visible only under the sun-light or UV light. lighting(365nm). The Inks are formulated for Silkscreen, Flexo-graphic, Rotogravure, Intaglio, Letterpress and Offset printing press methods6、光學變色油墨(角度變色油墨)
