Photoluminescent Signs with PermaLight

The signs store and emit energy under darkness.

Big Picture

Using the photoluminescent PermaLight flexible and rigid media from American Permalight, shops can use wide-format printers to print safety signs. The resultant photoluminescent signs absorb light from sunlight (or from an interior light source), store the energy, and then emit the energy as light under dark conditions over an extended period of time.

For use with both solvent and UV-curable rollfed and flatbed printers, PermaLight comes in a variety of styles"? including self-adhesive and non-adhesive flexible vinyl and polyester film, as well as rigid PVC and aluminum. It also is available in a range of luminance, for specific code and safety compliance.

The self-adhesive flexible vinyl films and colored vinyl films are 0.018-in. thick, including the paper liner; the selfadhesive polyester film is 0.012-in. thick with paper liner. The flexible vinyl and polyester films feature a glossy or matte surface and are available in rolls from 24- to 39 3.8-in. wide. These flexible films can be die-cut, kiss-cut, and punched.

The non-adhesive rigid PVCs are 0.045- to 0.059-in. thick, feature glossy or matte surfaces, and are available in 39 3.8 x 47 1.4-in. sheets. The rigid PVC can be cut to size using a process cutter or guillotine shears (or 3D signage can be created by heat-forming using a strip heater). The 48 x 40-in. rigid aluminum sheets have a matte surface and are 0.7- mm thick.

PermaLight's photoluminescent products are non-radioactive, non-toxic, lead-free, and contain no phosphor ingredients. In general, PermaLight is recommended for indoor use with a 25-yr life expectancy.
