A blacklight poster is printed with inks which fluoresce under blacklight. The inks contain phosphors which cause them to glow when exposed to the ultraviolet light emitted from black light bulbs.
Originating from the psychedelic 60s and 70s blacklights have seen a huge resurgence in the last couple of years and blacklights bulbs are now readily available through all good lighting and diy shops. Great for partys and dens.
THIS IS NON-FLOCKED WHICH MEANS IT IS NOT VELVET IT IS PAPER.
