How are holograms designed and printed?
Hologram is based on the principle of optics and requires a laser to make holograms. In fact, Dr. Gabor invented the process and gave the name hologram in 1948 and he was awarded a Nobel Physics prize in 1970. Dr. Gabor had to wait for the development of the laser to prove his theory and get recognition. Today holograms can be easily designed on the computer using any of the various drawings software and utilising the data to produce computer generated holograms on special optical equipment. Though the computer can be used to design a hologram it cannot transmit a holographic image nor can it reproduce a hologram on its screen. Hologram master is the key to security, it is like buying a lock, greater the specification, greater the security. A master is produced once so it is advisable to get the most appropriate specification for the application. The hologram master is used to make embossing plates to emboss metallised PET film and then it is treated with various coatings to suit end a
