According to the Nigerian Security Printing and Minting (NSPM), the ink stains on the newly recolored naira notes are security features that will allow Nigerians to easily identify counterfeit naira notes.
In response to Nigerians’ concerns about the quality of the newly designed naira notes, the managing director of NSPM, Ahmed Halilu, confirmed in a statement on Friday that the ink-staining naira notes were made of the same materials as the old ones and went through the same printing and finishing processes.
Mr Halilu claims that the ability of the new naira notes to leave intaglio ink traces when rubbed on completely white surfaces serves as a security feature that makes counterfeit money easy to detect.
“The second stage of currency printing necessitates a heavy deposit of special inks with relatively large particles to provide a tactile feeling of the portraits as well as other raised prints by design,” the NSPM MD explained.
