The Netherlands have gone where no man has gone before, in releasing a new generation of postage stamps. Lenticular “video” stamp uses a special printing process on a stamp-sized piece of plastic. The price is quite reasonable too, at €.39 (.46-cents US), especially when you think of how special this stamp really is.
Lenticular “video” is not the usual flat panel display, like the plastic hologram cards you tilt back and forth. Instead this is a technique that brings us as close to a real video, as you might expect from watching a video clip on your computer. According to an interview on Gizmodo, a website that specialises in hi-tech gadgets “It uses a specialised printing process that can show depth, motion, HD video, film or combinations of these. The lenticular material is made up of tiny ridges or lenses (hence the name “lenticular” printing). We take raw images and process them through a computer algorithm, which matches the lens surface of the lenticular material. When the two work together it enables the image to be replayed back to you. The printing is always on the reverse side of the Lenticular lens material, as this is where the focal point is, allowing the images to be replayed back to the human eye as the viewing angle changes.”
As this might go over the heads of many, we will simply go with the age old adage “A picture is worth a thousand words”.
