Abstract
An information based indicia (IBI) that does not require a FIM and is able to be read by Advanced Facer Canceller Systems. The foregoing is accomplished by printing on the mail piece an upper layer IBI indicia over a lower layer invisible ink. The lower layer ink is a dual luminescent ink that is invisible to the naked eye and the upper layer IBI indicia is printed with an ink that is visible to the naked eye. The lower layer may also be produced by two inks, one of which is fluorescent and the other of which is phosphorescent. The fluorescent ink will be printed in one area of the lower layer and the phosphorescent inks will be printed in another area of the lower layer.
