光變油墨光變油墨又稱光學變色油墨
光變油墨的印品色塊呈現一對顏色,例如:紅—綠、綠—藍、金—銀等。在白光下正看或側視,隨著人眼視角的改變,呈現兩種不同的顏色,光變特性強,色差變化大,特征明顯,不需要任何儀器設備都可以識別,光變油墨顏色角度效應無法用任何高清晰度的掃描儀、彩色復印機及其它設備復制,印刷特征用任何其他油墨和印刷方式都無法效仿,防偽可靠性極強,所以光變油墨被世界上多個國家指定用于要求最嚴、難度最大的貨幣和有價證券的防偽上,國內一些著名的廠家也將光變油墨用于包裝防偽上。
光變油墨按類型分為:干涉型、云母型、液晶型。

Optical variable ink is the most complicated intervention-type anti-forgery ink. The printing products using this ink has colorful metal luster in which color lump shows a pair of colors, red-green, green-blue and golden-silver, for example. Seen from the front or lateral side under sunlight, the ink glows two different colors varying with the viewing angle, characterized by intense optical variation and sharp color changes, whose color angular effect can’t be duplicated by high resolution scanner, color copying machine and other devices, and printing features can't be emulated by any other printing inks and printing types. With the unique design and special charm, it has become the rarely excellent anti-forgery ink and is recognizable without any devices. Furthermore, due to its complicated ink production process, huge investment, high anti-forgery reliability and involving high-technology in fields such as machinery, optics, electron, vacuum, superfine grinding, surface chemistry and high molecular material, it is applied in strictest and most difficult anti-forgery in currency and securities by many countries and in packing anti-forgery by some famous manufacturers.
