This guidance also forms part of the second edition of theFingermark Visualisation Manual (FVM). Further research has since been completed on 20 and 50 polymer banknotes.
As the initial research only focussed on uncirculated 5 and 10 notes, the Defence Science and Technology Laboratory (Dstl) has conducted additional work to ensure this guidance is still fit for purpose now that all denominations are in circulation.
The results of the study concur with the original research conducted on the Bank of England polymer banknotes by the team whereby Black Magnetic Powder (BMP) was the most effective as a single process, and was used in the most effective sequence. This study supports the current guidelines in the FVM with some additional considerations and conclusions.
