Abstract

Today we are facing many situations where the genuineness of the products and documents is questioned. Counterfeiting the original products has become a business of few people, which result in the degradation of quality of products, loss of money and loss of faith of end user. To prevent such malicious act, security features are added in the final product. Security printing is one of those methods that help in preventing counterfeit products and treachery. There are many different security features, which can be added in the security printing. Apart from those features, an embossed hologram is also included in prints to improve security features. However an embossed hologram is not a printed product.

In this Research for Master's Thesis I worked on the possibility of reproducing a hologram by printing. Initially we had an idea of using Collotype printing process, which uses the same base materials as of the holographic recording plate i.e. a Dichromated Gelatin (DCG) layer on a glass plate. However, it was found that this method is not suitable for reproduction of holograms. Then another method was tested which uses surface relief properties of holograms generated in DCG. The results give us the hope of Printing a Hologram, which is generated by IR Laser.
