There is an interesting reason for that. Hologram labels exist as an anti counterfitting device. Hence, the companies that invest hundreds of thousands of dollars in hologram printing machines have a vested interest in maintaining the efficacy of holgrams for anti counterfitting... so they don't print holograms for counterfitters. They actually call the companies... verify the order... verify the shipping address etc... to make sure the holograms are going to the real company.
In order to get fake holograms... counterfitters have to go with cheap print press sheets in cheap shops. They rarely get access to the good quality materials and presses.
