Beschreibung
Zusammenfassung:	An ink set with near infrared detection capability is disclosed. The ink set includes a cyan ink including a cyan colorant, a magenta ink including a magenta colorant, and a yellow ink including a yellow colorant, each of the colorants having maximum light absorbance in the visible wavelength range of about 400 to 750 nm, wherein each of the cyan, magenta and yellow inks includes a near infrared (NIR) absorbing pigment, which is different in spectral absorption characteristic from the colorant and absorbs light in the wavelength range of about 750 to 1200 nm.
