Customization of holograms can be made with WFT's drop-in capability long after the hologram has been originated. Drop-ins can be in the form of text, custom graphics such as a logo, or even a simple dot; the possibilities are endless. Typical images are simple diffraction gratings with various frequencies, matte white, dot matrix images, or patterns, and holographic optical elements (HOE) or Computer Generated Holograms (CGH). This technique greatly increases the difficulty of counterfeiting holograms and allows for a hologram to be updated with new information without the high cost of a new origination. All services are provided on a short lead-time, fast turn-around basis.
