How to Make Hologram?
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.
