Hot stamping involves a process in which a negative image consisting of
multiple layers of lacquer (one on top of the other) is applied to a foil.
The coated foil is then turned around and pressed onto the desired product
with a great deal of pressure and heat. Thanks to the adhesive layer,
the lacquer package detaches from the foil and adheres to the intended
surface

foils are used in the graphics industry, of course, but also in
the wood-processing and furniture-making industries.
DEGALAN® can help to create an incredibly realistic rootwood
design, for example, such as is used on the center consoles
in automobiles.
Ensuring that originals stay originals
This printing method serves not only to produce particularly
handsome and detailed designs; it also gives products effective
protection against counterfeiting. An example is the
hologram on the euro bills that represents one of the security
features. Tilt the note to a certain angle and what you see
on the film strip is the nominal value of the note, plus the
euro symbol, against a rainbow-colored background. This
hologram allows to check the authenticity of the notes. It,
too, is produced using the hot-stamping method.
Hence, DEGALAN® is found in paper currencies, bank
and credit cards, ID cards, and other documents. These
shiny images also feature on admission tickets for concerts
or sporting events. Just about everyone carries them around.
Because they are highly counterfeit-proof and to this day
non-reproducible, holograms are increasingly used to provide
protection against brand and product piracy. The trafficking
of fake and imitation products has now taken on an

Admission tickets for, say, a soccer match are particularly susceptible
to reproduction and counterfeiting. Holograms on the tickets in the form
of hot-stamped security foil make them forgery-proof
economic dimension that should not be underestimated.
This fact is reflected in significant losses in profit and puts a
serious strain on the economy.
Fakes are often times not discernible at first glance if the
packaging they come in has been really well reproduced.
Hot-steaming foils are used to print optical authenticity and
security features such as holograms on products. These holograms
have highly specific features; they are extremely
complex and difficult to copy. And so DEGALAN® is offering
a hand in protecting brands and products in that it makes it
possible for customers to distinguish between genuine and
fake goods. l
