WFT's Tooling department is known in the embossing industry for producing high quality and accurate step and repeat (recombine) holographic images. Unlike many other step and repeat systems that are limited by size, WFT can work with images as small as 0.25" x 0.25" and larger than 24" x 24". Working from photo-resist or nickel plates, a recombine (tiling up of images) can be made ready for electroforming up to 40" x 65". Surface relief structures that are holographic, computer generated, grayscale originated, E-beam generated, or diamond cut with structure depths from 0.01 micron to 150 microns have been recombined. Because of WFT's unique process, completed recombines can be back to the customer in as little as one day instead of weeks.
Drop-in
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. |
