PRINTED OBJECT

A printed object 100 comprises a substrate 10 and a first information code disposed on the substrate 10, wherein: the first information code is constituted of an infrared ray-absorptive ink layer 11 that has been printed with an infrared ray absorptive ink; and the infrared ray absorptive ink layer...

Zusammenfassung:	A printed object 100 comprises a substrate 10 and a first information code disposed on the substrate 10, wherein: the first information code is constituted of an infrared ray-absorptive ink layer 11 that has been printed with an infrared ray absorptive ink; and the infrared ray absorptive ink layer 11 is configured such that, when a laminated body constituted of a test substrate made of the same material as that of the substrate 10, and a test infrared absorptive ink layer made of the same material as that of the infrared ray absorptive ink layer 11 and disposed on the test substrate is subjected to a relative spectral reflectivity measurement on the test infrared ray absorptive ink layer side, with the test substrate as the reference (100% reflectivity), the minimum relative reflectivity in the visible region is 50% or higher, and the minimum relative reflectivity in the infrared region is 75% or lower.
