| New Currency Note Series of Central Bank of Sri Lanka |
Security Features
The notes contain several following current and new advanced security features
|
| 1. Note Printing Paper |
All currency notes manufactured with 100% cotton pulp. Therefore, these notes are harder and have a rough texture when touched than the normal printing paper and they also have a longer lifespan. Because of this features the genuine notes can be identified easily by touching them and feeling them with the fingers. These special security papers are manufactured securely by only a few producers in the world and therefore they are not available in the open market. |
| 2. Watermark |
The watermark is a feature which is inserted technologically to the paper at the stage of paper manufacturing. The watermark in the new note series is seen on the left corner on the obverse of each note. Significantly, it is the mirror image of the bird printed on the right on the obverse of the note. Accordingly, the watermark in each denomination is different. Unlike with notes issued up to now, the watermarks in the notes of new series vary from note to note with its denomination. In addition, an electro type watermark which includes the denomination in numerals appears vertically alongside with the watermark of the bird. All the watermarks can be seen with three dimensional effects. |
