Optically variable pigments

光學變色顏料

光變油墨又稱光學變色油墨和變色龍，印品色塊呈現一對顏色，例如：紅—綠、綠—藍、金—銀等。

Photovarying ink is also known as Optically variable pigments or chameleon, printing things present a pair of colors, such as red - green, green - blue, gold - silver and so on.

在白光下正視或側視，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，其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。

As the angle of view of the eye changes, the optical color-changing pigment will appear two different colors when viewed directly or laterally under white light. It has the characteristics of strong light variation and large color difference, which does not need any equipment to identify. This effect cannot be replicated with any high definition scanner, color copier or other equipment, and its printing characteristics cannot be replicated by any other ink or printing method.

其防偽可靠性極強，所以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已用于包裝防偽。

It’s security reliability is very strong, so many countries designated for the most stringent requirements, such as currency and securities security.Some famous domestic manufacturers have also been used for packaging security.
