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. On the
$50 notes, microprinting appears on the side borders
and in Ulysses Grant's collar. In 1990, 1993 and
1995 series notes, "The United States of
America" is printed repeatedly in a line outside
the portrait frame

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. |

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. 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. |
