Plate/Shim Making: Transferring 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: 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. 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 of its packaging or of a document.
Adhesive-coating and lamination: (only for pressure
sensitive label only): The “embossed” roll is continuously
coated on its reverse with a water-based / solvent-based
pressure sensitive adhesive and dried and is thereafter
continuously laminated with the silicon-coated surface of
the release paper to make a laminated roll.
Die-Cutting: After lamination, the laminated roll is
then duly in the size and the shape required by the customer
by a very specialized automatic die-cutting machine. For
jobs required in Spool Form the laminated rolls are slitted
as per size. Holograms in Sheet Form are best suitable for
manual affixations while Spool Form for automatic
affixations.
Finishing: Removal of the un-embossed portions of the
metallised polyester film from and side-trimming of each
sheet bearing several pieces of the hologram to make the
sheet uniform in size and facilitate removal of holograms,
one by one from the surface of the sheet.
The holograms are then sent to quality control
department, where each and every property of the hologram is
thoroughly checked and are finally these holograms are
counted, packaged and shipped.
