红外激发油墨
经红外光( 940 — 1060nm )激发而发出刺眼、鲜艳可见光的油墨称为红外激发油墨,颜色有红、绿、兰等。此油墨技术含量高,不易仿制,具有较高的防伪能力,适合在防伪印刷中广泛应用。现人民币、汽油票使用该技术。适用于所有印刷方式,例如,胶印、凹印、丝印、柔版印刷、凸印等。
1、 隐形无色荧光防伪油墨(UV and fluorescent security inks for invisible)
性能:紫外荧光油墨在紫外光(200-400nm)照射下,能发出可见(400-800nm)的油墨。通常指的短波紫外线激发可见荧光防伪印刷油墨,激发波长为254nm,长波紫外线激发可见荧光防伪印刷油墨,激发波长为365nm。这是一种技术成熟、使用方便的防伪油墨。适用于所有印刷方式,例如,胶印、凹印、丝印、柔版印刷、凸印等。胶印油墨包装为标准一公斤铁罐,凹印油墨包装为5升或10升塑料桶。

2、 有色荧光防伪油墨(UV and fluorescent security inks for visible)
有色荧光防伪油墨在日光下显示出油墨的本色,在验钞机或紫外光下可显示出与油墨原有颜色一样或者不一样的鲜艳的荧光颜色,该油墨有不同的颜色可供用户选择。适用于所有印刷方式,例如,胶印、凹印、丝印、柔版印刷、凸印等。胶印油墨包装为标准一公斤铁罐,凹印油墨包装为5升或10升塑料桶。

The Inks are formulated for Silkscreen, Flexographic, Rotogravure, Intaglio, Letterpress and Offset printing press methods.
3、 红外防伪油墨(IR security inks for invisible or visible)
性能:红外防伪油墨是在红外光(780-980nm)激发下,能发出鲜艳黄绿色光的油墨。适用于所有印刷方式,例如,胶印、凹印、丝印、柔版印刷、凸印等。 胶印油墨包装为标准一公斤铁罐,凹印油墨包装为5升或10升塑料桶。

4、 热敏油墨(Thermo-chromic Inks)
热敏油墨又称热变色油墨、温变油墨。指在10-60℃摄氏度加热作用下,能发生变色效果的油墨。热致变色的原理是在加热情况下使变色化合物发生物理构象变化带来自身的吸光性变化。 主要适用于凹印、丝印印刷方式,也可以胶印、柔版印刷、凸印等。胶印油墨包装为标准一公斤铁罐,凹印油墨包装为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、 日光激发变色油墨(Sun-light sensitive security ink)
性能:日光激发变色油墨是在太阳光(也可在紫外光)照射下,能发出可见光400-800nm的防伪印刷油墨。这种油墨从应用来看是由于太阳光作用而变色,实质上也是受紫外线照射而变色的。适用于所有印刷方式,例如,胶印、凹印、丝印、柔版印刷、凸印等。胶印油墨包装为标准一公斤铁罐,凹印油墨包装为5升或10升塑料桶。
