Rs.1000 notes introduced in October 2000 contain a readable, windowed
security thread alternately visible on the obverse with the inscriptions
‘Bharat’ (in Hindi), ‘1000’ and ‘RBI’,
but totally embedded on the reverse. The Rs.500 and Rs.100 notes
have a security thread with similar visible features and inscription
‘Bharat’ (in Hindi), and ‘RBI’. When held
against the light, the security thread on Rs.1000, Rs.500 and
Rs.100 can be seen as one continuous line. The Rs.5, Rs.10, Rs.20
and Rs.50 notes contain a readable, fully embedded windowed security
thread with the inscription ‘Bharat’ (in Hindi), and
‘RBI’. The security thread appears to the left of
the Mahatma's portrait. Notes issued prior to the introduction
of the Mahatma Gandhi Series have a plain, non-readable fully
embedded security thread.
On the obverse side of Rs.1000, Rs.500, Rs.100, Rs.50 and Rs.20
notes, a vertical band on the right side of the Mahatma Gandhi’s
portrait contains a latent image showing the respective denominational
value in numeral. The latent image is visible only when the note
is held horizontally at eye level.
This feature appears between the vertical band and Mahatma Gandhi
portrait. It contains the word ‘RBI’ in Rs.5 and Rs.10.
The notes of Rs.20 and above also contain the denominational value
of the notes in microletters. This feature can be seen better
under a magnifying glass.
The portrait of Mahatma Gandhi, the Reserve
Bank seal, guarantee and promise clause, Ashoka Pillar Emblem
on the left, RBI Governor's signature are printed in intaglio
i.e. in raised prints, which can be felt by touch, in Rs.20, Rs.50,
Rs.100, Rs.500 and Rs.1000 notes.
A special feature in intaglio has been introduced
on the left of the watermark window on all notes except Rs.10/-
note. This feature is in different shapes for various denominations
(Rs. 20-Vertical Rectangle, Rs.50-Square, Rs.100-Triangle, Rs.500-Circle,
Rs.1000-Diamond) and helps the visually impaired to identify the
Number panels of the notes are printed in
fluorescent ink. The notes also have optical fibres. Both can
be seen when the notes are exposed to ultra-violet lamp.
This is a new security feature incorporated
in the Rs.1000 and Rs.500 notes with revised colour scheme introduced
in November 2000. The numeral 1000 and 500 on the obverse of Rs.1000
and Rs.500 notes respectively is printed in optically variable
ink viz., a colour-shifting ink. The colour of the numeral 1000/500
appears green when the note is held flat but would change to blue
when the note is held at an angle.
The small floral design printed both on the
front (hollow) and back (filled up) of the note in the middle
of the vertical band next to the Watermark has an accurate back
to back registration. The design will appear as one floral design
when seen against the light.
Printing and circulation of forged notes
are offences under Sections 489A to 489E of the Indian Penal Code
and are punishable in the courts of law by fine or imprisonment
