Abstract: The present invention comprises a light emissive display comprising one or more photoluminescent printed waveguides. The waveguides are coated with one or more layers of an overprint varnish. The overprint varnish eliminates surface texture produced by the photoluminescent printing, rendering the waveguides transparent when in the non-energized state.
