Printing security with OVI inks

OVI – color that changes with the change in the viewing angle OVI (Optically Variable) inks are an advanced security technology that is based on changing the color of the print depending on the viewing angle. This effect is possible thanks to special pigments that reflect light in a way unique to this technology, changing color depending on the angle of view. Security features made with OVI paints are easy to verify visually and extremely difficult to counterfeit, making them ideal for protecting securities and other products that require anti-counterfeiting. They enable the creation of dynamic security that is visible to the naked eye, which makes it much more difficult for counterfeiters to operate.
