Watermark

Each currency note depicts a different bird as the watermark, which is the same bird portrayed on the note. In addition, the value in numerals appears vertically as a highlighted watermark.

Security Thread

The security threads are different for each denomination, and have the letters "CBSL" and the value. e.g.: Rs. 20, Rs. 100. The width of Starchrome® thread which changes colour from red to green in Rs. 5000, Rs. 1000 and Rs. 500 are 3mm, 2.5mm and 2mm, respectively. The thread in Rs. 100, Rs. 50 and Rs. 20 is embedded in the currency note.

Cornerstone®

Cornerstone® watermark appears in the form of diagonal bars at each corner of every currency note.

See through

When the note is held up to the light, the numeral value of the note on the front comes together with perfect register with the reverse on the back of the note.

Extra Small Text

When viewed closely, an area of text reading "CBSL" and the numeral value can be seen.

Blind Recognition Feature

A vertical order of heavily printed dots (with one dot for Rs. 20 currency note) progressing according to denomination appears on the left hand side of the currency note to help the visually impaired to recognise the denomination.

Run fingertips across the note and feel the raised printed areas. (e.g.: the Central Bank title, tactile bars, central images etc.).
