Infrared-Absorbing Ink: The Cutting-Edge Technology for Security and Printing Applications
Infrared absorbing (IR-absorbing) ink is a specialized type of ink that absorbs infrared light while remaining transparent or covert under visible light. This unique property makes it invaluable in security printing, anti-counterfeiting, and advanced industrial applications. Unlike conventional inks, IR-absorbing ink interacts selectively with specific wavelengths of light, enabling features such as machine-readable codes, invisible markings, and secure authentication.
