Microlettering:
| This
print appears as a thin line to the naked eye, but
the lettering easily can be read using a low-power
magnifier. The resolution of most current copiers
is not sufficient to copy such fine print. |

Color
shifting ink:
These
inks, used in the numeral on the lower right corner of the
face of the note, change color when the note is viewed from
different angles. The ink appears green when viewed directly
and changes to black when the note is tilted.

Security
thread:
A
security thread is a thin thread or ribbon running
through a bank note substrate. All 1990 series and later
notes, except the $1, include this feature. The note’s
denomination is printed on the thread. The denomination
number appears in the star field of the flag printed on
the thread. The thread in the new notes glows when held
under a long-wave ultraviolet light. Since it is visible
in transmitted light, but not in reflected light, the
thread is difficult to copy with a color copier which
uses reflected light to generate an image. Using a
unique thread position for each denomination guards
against certain counterfeit techniques, such as
bleaching ink off a lower denomination and using the
paper to "reprint" the bill as a higher value
note. |

|
Watermark
The
watermark is formed by varying paper density in a small
area during the papermaking process. The image is
visible as darker and lighter areas when held up to the
light. Since the watermark does not copy on color
copiers or scanners, it makes it harder to use lower
denomination paper to print counterfeit notes in higher
denominations and is a good way to authenticate the
note. It depicts the same historical figure as the
engraved portrait. |

UV
Flouroescence:
|
Ultra
Violet inks are used in the printing process of
the note. The security thread and special colors
of the note are visible when the note is lighted
by an UV light making the note difficult to falsificate. |
Infreared
features:
The
latest feature in the banknote printing process is represented
by the INFRA-RED ink. It's use has increased in the last years,
since the properties of this special ink make the banknote
difficult to falsificate. The IR ink, not visible at naked eye,
can only be seen by lighting the note with an infra-red light.
