我们是一家长期致力于光学变色颜料研发和生产的高新技术企业，多项关键指标达到国际领先水平。
We are a high-tech enterprise that has long been committed to the R& D and production of optically variable pigments, whichmany key indicators have reached the international leading level.
Optically variable pigments
光学变色颜料
光变油墨又称光学变色油墨和变色龙，印品色块呈现一对颜色，例如：红—绿、绿—蓝、金—银等。
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.
在白光下正视或侧视，随着人眼视角的改变，呈现两种不同的颜色，光变特性强，色差变化大，特征明显，不需要任何仪器设备都可以识别，其颜色角度效应无法用任何高清晰度的扫描仪、彩色复印机及其它设备复制，印刷特征用任何其他油墨和印刷方式都无法效仿。
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.
其防伪可靠性极强，所以被世界上多个国家指定用于要求最严、难度最大的货币和有价证券的防伪上，国内一些著名的厂家也已用于包装防伪。
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.
