Holographic Printing

  Hologram is a three-dimensional image created by lasers.
White light reflection holograms are monochromatic, and white light
transmission (or rainbow) holograms show a spectrum of colours. The
latter may be mass produced by embossing it on polyester film and thus
called “embossed hologram”, which is used as an authenticating feature in
credit cards to prevent forgery or as decoration in promotional literature.
Holographic printing was among the first process to introduce laser
technology in the field of anti-counterfeiting. In addition to the prevention
of forgery in securities and documents, holographic printing is widely
applied in packaging, covering anti-counterfeiting labels for commodities
and anti-counterfeiting packaging materials. At present, packaging using
laser holographic image can be divided into packaging boxes, forming
packaging, flexible packaging, labels, wrapping paper and so on.
In recent years, laser hologram labels have developed rapidly with
very high potentiality. Laser tags can apply to a variety of different
products to achieve the purpose of anti-counterfeiting, such as the
commonly used drugs, clothing tags, cash coupons, cell phone
batteries and limited editions of toys. Besides, holographic image
technology can also apply to a lot of materials, such as typical credit
cards, certificates and even bank notes of
some countries can be hot-stamped with
laser holograms instead of sticking in the
form of labels.
  In addition to providing identification
information, laser tag has also become part
of the overall image and brand recognition
of a product, and is playing an increasingly
important role. Besides the anti-counterfeiting
effects brought to the packaging of products,
laser hologram paper can also beautify the
products, improve product quality, and enhance
the promotion and sales of products. Growing
popularity of application of laser hologram
labels is expected in future market, and through
the use of laser holographic paper together with
spot foil-stamping and cold stamping, both the
purposes of security and beautification can be
realized from the effects of the labels.
The current 3-dimensional holographic
laser printing technology uses composite
holographic photography to improve 3D sense
of printed materials, that is, the printing of
four-dimensional laser holograms. It combines
laser, precision machinery and chemical physics, and many other up-to-date
scientific and technological achievements, adopting hundreds of frames
of original information (obtained through collection, coding and modeling)
and combining them together with laser holography system, leaving almost
no chance for imitation of the hologram. At the same time, its feature of
strong three-dimensional images will allow consumers easily identify the
authenticity of goods with their naked eyes.
The application of holographic printing in publications include the use
of 3D holographic effects and the brilliant colours of rainbow hologram
to produce special holographic arts, book covers, illustrations, greeting
cards, calendars, and other works with high artistic appreciation value.
The application of holographic printing in interior decoration and
packaging also include the diffraction pattern of the embossed foil
(also known as laser foil), the diamond film or crystal rainbow film. As
a result of their unique brilliant colours and rich patterns of changes,
they are widely used in interior decoration, beautification of furniture
edges, gift packaging, and decoration of commodities.
As a supplementary means of marketing, embossed holograms are
receiving special attention by the food industry. Many food manufacturers
stamp embossed holograms onto the packaging and decoration of their
products, and some put the holograms inside the packing to attract
buyer’s (especially children’s) interest in purchasing the food.
Beijing is a strong and diversified production base for laser
holographic trademarks. In addition to holograms, the scope of application
of laser technology in anti-counterfeit includes carved numbering, colour
numbering and three-dimensional holographic true colour.
