Zusammenfassung:	A system for storing information (20) including a first partial portion (24) of a printed marking, and a second partial portion (22) of the printed marking. The printed marking comprises first information in a first information storage format. The first partial portion (24) is printed with a first ink. The second partial portion (22) is intermixed with the first partial portion to form the printed marking. The second partial portion (22) is printed with at least one second different ink. The second ink comprises a metameric ink which becomes excited when exposed to an excitation source such that the printed marking contains second different information in a second different information storage format which can be read when the printed marking is exposed to the excitation source.
