Clearing the air on speculation over quality control measures in currency note printing, the Reserve Bank of India on Friday said that the process and system followed for production of Indian banknotes are at par with the best practices adopted globally.
In line with the same, banknote quality is maintained well within the various tolerance parameters for dimension, placement of design, print features etc. The currency printing presses are equipped with state of the art machinery, documented systems and technically qualified personnel through which quality control is ensured at each stage of banknote production, it said.
The central bank said that there are integrated systems in place for inspection of each single note at high speed. These systems validate the security features and print quality of the notes. The stringent quality control procedures also include various online and offline systems for inspection of final product quality. Labs with specialized paper and ink testing facilities, which verifies the specification parameters are available in the presses.
There are standard tolerance limits prescribed for certain features of the note, viz., security thread width, wandering of watermark and security thread, and cutting accuracy. RBI rarely receives complaints from the members of public on banknotes with features beyond the acceptable tolerance levels. A standard operating procedure is in place for dealing with such rare cases wherein each such note is examined and corrective steps taken, if necessary, it added.
