Managing dual color properties with the Z-parameter in the visual and NIR spectrum

► Value Z is added for color description for managing dual color properties. ► It is the numerical value of matter absorption in the NIR-Z spectrum. ► It is suggested to incorporate Z values in all commercial inks. ► Inks are planned for two independent graphics, each in its own wavelength area. ► The new application of inks in industrial, art and security purposes is achieved.
