Malaysia 12th Series RM10 Banknote With "Ink Drop" Inking Error.
Last year, Mr. Wei Notes, a Malaysia numismatist sent me a piece of Malaysia 12th series RM10 banknote with half of the Agong's face on the portrait is dark in colour. The Rafflesia flower on the reverse is also in black-dark colour. (Normal colour:Yellow).
They have tried with many attempts to find out from our Bank Negara Malaysia (BNM), whether this banknote is an original error banknote or a post print error banknote. Mr.Wei Notes told me that a spoke men from BNM told them it is a real banknote but he can't explain why half of the Agong's face on the portrait is dark in colour and the Rafflesia flower on the reverse is in black-dark color.
Today, I met a very experience printer. I took the chance to show him the error RM10 banknote. He told me, it is likely a "Ink Drop" inking error printed banknote. An over-inking error occurs when a surplus of ink is delivered to the plate or accumulates at a particular location on the plate.
He explained to me in more details. A banknote is printed by many runs, the Agong's portrait is printed in one run and the Rafflesia flower design is printed in an other run by a different nylon plate. He said that it was likely a large drip of dark ink was dropped on to the nylon plate that was having a raised image of the Rafflesia flower design by mistake during the printing proses. Hence, the early printed banknotes with the dark inked Rafflesia flower nylon plate will produced a dark coloured Rafflesia flower. The dark colour on the Rafflesia flower will be faded on the subsequent pieces of the RM10 banknotes. The same inking errors was happened on the Agong's portrait.
A note will be under-inked when the engraved plate pressing on a sheet of currency paper does not received a sufficient supply of ink. Under-inking may occur for a single colour or different colour inks, in which case correspondingly different design portions of a note will appear with weak, faded or even no colour design.

Last year, during the Chinese New Year, many pieces of Malaysia RM10 banknotes were found with the Portrait of Agong printed without any colour. There were  occurred likely the nylon plate used to print the Portrait of Agong was not received a supply of ink during the printing process. It was a under-inked error banknote.

This RM10 Banknote is a courtesy of Wei Notes. Thank you very much.
