Hologram
was invented by Physicist Denis Gabor in 1948.
A Hologram is not made by printing or by some kind of ink as
is commonly supposed but by the sophisticated technology of
Laser Optics.
A Hologram is a visual medium providing a high potential
image in three dimensions (3 D) making it instantly
recognizable to the naked eye and uniquely resistant to
counterfeiting. Holograms, with their high-quality,
high-definition optical image, are very effective in
combating fraud.
Apart from the three-dimensional Effect and the depth effect
which are the basic features of the hologram, during the
process of holographic recording (which is the same as the
process of Master Origination) it is possible to create
other effects such as The Animation Effect, The Dynamic
Effect, The Kinetic Effect etc. and also to conceal code
letters or numbers or secret images or incorporate
Micro-Lettering in one of the layers of the Hologram. These
are some of the typical optical security features
incorporated in Holograms to make them impossible to
replicate. Some of these features can be viewed only with
the aid of special viewing instruments or under special
lighting conditions.
The lacquering on the film is done to impart an additional
security feature, namely the property of “Tamper-Evidence”.
If any one tries to remove a hologram, only the bare
polyester film will come off in his fingers, leaving the
impression/ image of the hologram on the surface on which it
was originally affixed, thus revealing the evidence of
tamper with the hologram.
Being a three dimensional impression and virtually
impossible to replicate, a security hologram is an
inimitable symbol of genuineness and has extra-ordinary
visual appeal when viewed under any type of natural or
artificial light as it displays the different colours of the
spectrum i.e. colours seen in a rainbow.
 In Today’s world every manufacturer and organization would
obviously like to protect his or her brand or document
against spoiling its spurious duplicates, imitations or
look-alikes thus eating into its profit and brand name. This
is where the security hologram comes in, providing that
extra protection a brand or document.
