What's the downside?

Using holograms for security measures sounds almost perfect, but it is just that … almost perfect. There are some negatives that converters need to keep in mind before they start using holographic substrates.

One main factor, like everything else in today's world, is cost. But, as Gettinger said, "The increased use of holograms has helped drive costs down through both the better manufacturing scale of existing suppliers and the entrance of new hologram manufacturers, which increases supply," she said. Gettinger also suggests to anyone getting into the holographic business for the first time to spend the capital up front, to make sure they buy the best equipment and materials possible. "By purchasing ready-to-print materials, many headaches and costs can be eliminated," she said.
