Today most of the popular brands, big departmental stores, as well as manufacturers of electronic items, etc. are worried about the safety of their brand as well as products. Their popularity has increased the risk of being copied or forged which can directly affect their revenue. Holographic security stickers have gained popularity for the last few years due to this increasing insecure feeling of business houses. The introduction of holographic stickers has revolutionized the entire world as most of the industries are using these stickers for the security of their business and products as they are difficult to copy due to their complex design and structure.
Before discussing the techniques used to make holographic stickers you must know what they are, how they are produced and how they work. The information provided in this write-up can help you in this regard.
What Is a Holographic sticker?
An image designed with a 3D effect printed on a 2D surface is known as a hologram. The process of making these holograms is known as holography and for that reason, they are also called holographic stickers. These stickers include complete information about the brand and its products and for that reason, they are used as security stickers to enhance the security of the products.
The techniques used for making these complex stickers must be something extraordinary. Brief information in this regard is provided hereunder for your consideration.
Techniques used for making holographic stickers
Two laser beams are used to produce a photograph with a 3D effect to be printed on a 2D surface to create holographic security stickers. A laser beam emits light of different colors depending upon its wavelength. To create colorful images, a laser beam is passed through a shutter to throw light on the surface at an angle of 90 degrees. When the shutter is activated then it splits the light into two beams or blocks the light to create images with different color effects.
When the shutter splits the laser beam into two beams then one beam, known as reference beam’, radiates on the film directly and the second beam is reflected away from the object of which you want to create a holographic sticker.
A pattern known as an interference pattern is created when both of these beams intersect each other. You can see well-defined fringes on the screen created by the interference of these two beams. The beam should be highly stable because the interference pattern projected on the screen is very sensitive and the image can be spoiled even with a little vibration of any kind.
Once you have a stable laser beam you can easily record the reference pattern on the film. You can see the entire 3D image of the object on the film after developing it. You can use this film to create holographic stickers for your company.
