Abstract
A double-sided edge-lit display sign (10) comprises an opaque core sheet (13) and a sheet (12) formed from a material having a high light transmissivity mounted to each surface of the core sheet (13) and carrying a design applied to the outer surface thereof, in which an array of essentially opaque dots (15) is applied to the outer surface of each light-transmissive sheet (12), beneath the design. Preferably, the dots (15) are white and are painted or screen printed, the density increasing towards the centre of the sheets. Increased surface illumination is achieved for a given light source.
