2.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.

3.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.
