Abstract
A ink that is printed under a printed information-based indicia so that the information-based indicia will not require a Facing Identification Mark (FIM). The ink provides the foregoing result by being both fluorescent and phosphorescent. Current desk top printers and color photocopiers are not capable of duplicating fluorescence and phosphorescence at the same time.
