Minting Company says Ink Stains from New Naira Notes are Security Features

According to the Nigerian Security Printing and Minting (NSPM), the newly colored naira notes' ink stains serve as security measures that make it simple for Nigerians to spot counterfeit notes.

As Nigerians continue to voice concern about the new naira notes’ durability, the managing director of NSPM, Ahmed Halilu, revealed this information in a statement on Friday in response to Nigerians' concerns about the quality of the newly designed naira notes. 

He also confirmed that the ink-staining naira notes were made of the same materials as the old ones and underwent the same printing and finishing procedures.

Mr. Halilu claims that the new naira notes' security feature, which makes it simple to identify counterfeit money, is their capacity to leave intaglio ink traces when rubbed on totally white surfaces.

"The second stage of currency printing (intaglio) requires a heavy deposit of special inks with fairly large particles to give a tactile feeling of the portraits as well as other raised prints by way of design.

"One of the properties of intaglio inks is non-solubility in water and ease of transfer (light stain) on plain white materials owing to the size of the particles.

"This is generally a security feature of all banknotes that easily differentiates them from forged or counterfeited notes," the NSPM MD said.
