In this market of false and fabricated products the use of hologram sticker for security benefits are unparallel. Such stickers are more popular and highly in demand compared to other visual mediums that represent visuals on a two-dimensional surface, as they are holographed with an added dimension of depth.
These days hologram stickers are used to carry a multiplicity of messages in a wide range of shapes, sizes and forms across a large spectrum of products and objects. Such stickers are self-adhesive and tamper proof hologram stickers, offering verification, security and protection against imitation.
What are its types?
DOT- MATRIX Holographic sticker – The dot- Matrix hologram features unlimited computer controlled and laser beam engraved dots. Each dot means a separate diffraction grating that creates a striking impact of variable images on a single sticker. Such hologram stickers can have lots of zooming, moving and flipping effect that adds as bonus to their popularity.
True color Holographic sticker – True color holograms are such holograms that are made up of photographic quality artwork. These stickers are much in demand, as they are a very good way to achieve anti-counterfeit performance.
2D/3D hologram stickers – These hologram stickers are made up of multiple two-dimension layers. Here you will find images lying one over other with visual depth which create an effect of three dimensional structure on the stickers.
Flip-Flop holographic sticker – Flip-flop holograms are unique holograms that boast of displaying two images from two different viewing angles. In other words, when the viewing angle changes left to right or upside and down, different images are seen emerging through hologram.
Application of Hologram stickers
Hologram stickers are mainly used to improve security and brand image in various types of industries. Such stickers are used as a very attractive and practical option in product packaging and security applications. Its applications are found in fine jewelry, watches, automotive or engineering machine parts, driving licenses, certificates, bank cheques, passport, revenue stamps etc.
Make hologram in the most easiest way as it is nothing more than illuminating the 3-D object with help of a powerful laser light. The object reflects the light rays and the pattern is recorded on a particular type of plate which is also known as holographic plate. On being developed it recreates the original object. The image gives the impression of a 3D object. This is indeed an easy way to make a hologram by yourself. Moreover, they can be used a wonderful gift too. However, there are certain steps involved in the making of holograms. They are as follows:
Make Hologram – Mastering
The laser which illuminates the object actually helps the reflected ray to fall on the photoresist plate. Another reference light beam falls on the light beam directly and this causes interference between two rays to react with the photosensitive coating and provide a holographic image. The plate where the original hologram is located is given a chemical bath with the help of standard photographic developers.

Make Hologram – Electroforming
The plate is then sprayed with silver paint to make it a better electrical conductor and is then finally electroplated with nickel. Once it’s electroplated, it is washed with deionized water and the thin nickel coating or shim is removed. The negative image of the hologram is intact in the master hologram. The process is used to produce several shims and these shims are called “mothers,” “daughters,” and “stamper shims, in accordance to the generation. The stamper shims, having negative images are used in the later part when the final product holograms are printed.
Make Hologram – Embossing
The embossing machine is responsible in making the shim push the holographic image on to the film. The embossing machine has the stamper shims, a roll of polyester film which is coated with acrylic coating. All these work under tremendous heat and pressure to serve the purpose.
Make Hologram – Metallizing
The aluminum wire is heated to 2000°F or 1,093°C inside the vacuum chamber and the roll is exposed to the vaporising wire. Then the film is treated to provide the moisture it has lost in the vacuum. The last step involves applying a coating of lacquer so that it can be imprinted with ink.
Make Hologram – Converting
Steps may be different for different types of film. There are films which needs to be laminated by paper board or printed with messages. Moreover, there are pressure sensitive adhesives added to holograms so that it can be later fixed to a particular product.
Make Hologram – Finishing
The finishing part involves fixation of it to other products or packaging for shipment.
