HoloSeal™ authentication labels feature JDSU holographic imaging technology, as well as a customized tamper-apparent break pattern, black light verification system, and machine-readable embedded code to protect against counterfeiting, tampering, and product diversion. In addition, HoloSeal can be manufactured as transparent or semitransparent to allow printed regulatory or marketing copy to be visible through the hologram. HoloSeal labels are manufactured to meet the requirements of most commercial application environments.
