Understanding Holograms
Uniqueness is inherent in the very process of Holographic Recording. If a holographer
makes the same hologram at two different times, or two holographers make the same hologram
at the same time, recording from the same positive” for each layer, minute examination will
reveal subtle differences between each version of the same hologram.
A Hologram is the “Interference Pattern” on the photosensitive coating on the surface of
the glass plate, created by the interaction of two beams of coherent light from a laser. Each time
a holographic recording is undertaken, there will be subtle variations in the above referred
“Interference Pattern”, making such patterns unique. Thus, uniqueness is inherent in the very
process of holographic recording. It is not possible to make an exact replica of a hologram
and hence it is regarded as virtually impossible to replicate.
A special chemical coating known as Tamper-Evident Coating applied on the Base
Polyester Film, imparts an additional security feature to the hologram to detect any attempt at its
unauthorized removal from the surface of a product or its packaging, or from a document.
Additional Security Features, other than Holographic Features, which can be
incorporated in a Hologram
 DNA printing: We provide full printing service of synthetic invisible DNA which assures
its originality. It is impossible to replicate.
 Inkjet Numbering: We can provide continuous inkjet alphanumeric numbering or
separate codes like year of manufacturing etc. on each hologram to ensure 100%
accountability of each and every hologram.
 UV Numbering: We can provide continuous UV alphanumeric numbering or separate
codes like year of manufacturing etc. on each hologram which will not be visible to the
naked eye and can be seen using an Ultra Violet Light.
 Laser etching: We can provide laser etching on the holograms which is a permanent
impression on the hologram. The laser etched portion in the hologram adapts the colour
of the substrate on which it is etched. Laser etching can include codes, alphanumeric
continuous numbering, year, signature etc.
 Thermal Numbering: We can provide continuous thermal alphanumeric numbering or
separate codes like year of manufacturing etc. on each hologram to ensure 100%
accountability of each and every hologram.

Manufacturing Process
Described below is the process of making a typical two-layer “Embossing Reflection
Hologram”, by far the most common and cost-effective hologram with two common sub-
types, namely the two layer hologram (with a background image and a foreground image) and
the three layer hologram (with a background image, a middle ground image and a foreground
image).
Artwork Design: Using computer graphics, the artwork is generated on the computer as
a conceptual design, wherein certain parts of graphical elements of an image which the
customer would like to appear in his hologram are recorded in the background (the bottom
layer) and other parts of the graphic elements in the foreground (the top layer).
Making the artwork “camera ready”: Using the computer graphics and working with
the shape and size chosen by the customer for his hologram, the graphic components of each
layer are separately recorded on paper as many times as can be accommodated on an area of
roughly six square inches.
Image-Setting: Photo images are taken using a special cameras to capture “the
positive” and “the negative” of each layer from the camera-ready artwork.
Holographic Recording and Master Origination: Exposing “the positive” of each layer
one after the another to laser light, with the aid of specialized imaging devices such as
specialized lenses and mirrors, records those images on the surface of an ultra-clean, photo
sensitive and specialized glass plate, to originate “the Glass Master”. At the end of this intricate
and time-consuming process, the original two dimensional image elements of the artwork gets
“transformed’” into a “three dimensional” impression on the surface of “the glass master”, called
the hologram. The hologram will diffract the seven colours of the spectrum (colours seen in a
rainbow) and will produce “the depth effect”, or the three dimensional (3D) effect, which if
viewed from different angles under any type of natural or artificial light, gives the hologram its
extraordinary visual appeal. During holographic recording, secret information (e.g. code
numbers) can be recorded and concealed in any one of the layers of the hologram to
make it machine readable (that is, it can only be viewed under special lighting conditions and
with the aid of special viewing instruments) impart the unique “optical security feature” to the
hologram.

Plate/Shim Making: This process transfers the multi-coloured, three-dimensional
impression of the hologram from the surface of the glass master to the surface of a nickel plate
to create “the nickel master”. (After this, the glass master cannot be used any further and has
to be discarded). By the same process and from “the nickel master”, additional nickel plates,
also called “shims” are prepared for ultimate use in the embossing machine for mass
production.
Embossing: By transferring the multi-coloured, three-dimensional impression of the
hologram from the surface of the shim to the surface of very thin, metallised polyester film roll,
through optimal application of heat and pressure, the holographic film is created. A special
chemical coating known as “Tamper Evident Coating’” on the base of the polyester film imparts
an important additional security feature to the hologram, to detect any attempt at its
unauthorized removal from the surface of a product or its packaging, or from a document.
Adhesive-coating and lamination (for pressure sensitive labels only): The
“embossed” roll is continuously coated on its reverse with a water-based / solvent-based
pressure sensitive adhesive and dried and is then continuously laminated with the silicon-coated
surface of the release paper to make a laminated roll.
Die-Cutting: After lamination, the laminated roll is cut through the hologram layer, but
not through the backing release paper layer, to the size and the shape required by the customer
using a very specialized automatic die-cutting machine. For jobs required in Roll Form the
laminated rolls are slit to the required width. Holograms remaining in the Sheet Form are
suitable for manual application while Roll Form is best for automatic application or for use by
hand applicators similar to supermarket price applicators.
Overprinting: If required, any additional security elements are added at this stage while
the film is still in its large roll form. The addition of DNA, UV, Security Optical Markers,
Alphanumeric numbering (inkjet, thermal or laser) are all added at this point in the production
process.

5. 5
Finishing: This required the removal of the un-embossed portions of the metallised
polyester film from around each stamped shape allowing the removal of each hologram - one by
one from the surface of the sheet or roll.
Quality Control: The holograms are then passed through the quality control
department, where each and every property of the hologram is thoroughly checked before the
holograms are counted, packaged and shipped.

Origination Techniques
Holograms can be made using both Traditional (Analogue) Holographic Techniques and
Digital Holographic Manufacturing Techniques. We offer both Traditional and Digital Holograms,
details of which are given below:
2D/3D: These are by far the most common type of holograms. These holograms (and
therefore the artwork of these holograms) may be of two layers (i.e. with a background and a
foreground) or of three-layers (with a background, a middle ground and a foreground). The
image elements of the middle ground and the foreground in the case of three-layer holograms
and the image elements of the foreground in the case of the two-layer holograms are usually
superimposed over the image elements of the background of the hologram. These holograms
display a unique multilevel, multi-colour effect and typically have one or two levels of flat
graphics “floating” above or at the surface of the hologram. The graphic elements in the
background appear to be “under” or “behind” the hologram, giving the illusion of depth.
Apart from being the most cost-effective type of holograms, the 2D/3D Holograms, when viewed
under a variety of sources of light, are extremely eye-catching.
Dot Matrix Technology: The holograms produced using Dot Matrix technology are
considered to be one of the most secure holograms internationally. These holograms are
originated using a highly sophisticated and very expensive Dot Matrix System. This kind of
technology allows the creation or originals of holograms with a resolution of up to 10 microns.
Dot Matrix technology makes it possible to create originals of computer synthesized holograms
with a high level of protection. The hologram includes elements that cannot be manufactured
using other optical or printing technologies as it incorporates the development of various
algorithms for designing the optical elements that shape the scattered radiation patterns.
E-Beam Technology: The holograms produced using electronic beam technology, are
considered to be the most secure holograms internationally. These holograms are originated
using highly sophisticated and very expensive E-Bean Lithography systems. This sophisticated
level technology allows creation of originals of holograms with a resolution of up to 0.1 micron.
Electron Bean technology makes it possible to create originals of computer synthesized
holograms with even higher levels of protection. The hologram includes elements that cannot be
manufactured using other optical or printing technologies as the technique requires the
development of various algorithms for designing the optical elements that shape the scattered
radiation patterns. This origination technique offers many possibilities for combining various
security features. The technology of computer synthesis of holograms opens ample
opportunities for the creation of OVD with the highest level of security.

Our Holographic Products
Holograms on sheets: The holograms are supplied in sheet form suitable for manual
application. Each Sheet is serially numbered (if require) for proper accountability of the
holograms. There is no gap required between adjacent hologram for square hologram with
sharp edge corners, but a gap of 3 mm is required for circular and rounded corner holograms.
In Rolls: The holograms are supplied in rolls with a gap of minimum 2.5-3 mm between
each hologram. These holograms can be applied both manually and automatically using
automatic labelling machines.

8. 8
Holographic Strip: The impression/ images of the hologram are embossed on
lacquered (tamper evident coating), metalized polyester film and then a special heat activated
adhesive coating is provided in the foil which enables the user to laminate the holographic strip
to the substrate using an attachment in the customer's existing lamination machine or using an
automatic lamination machine.
