Abstract: A phosphorescent writing sheet and system along with methods of production and use are provided. The writing/drawing system includes a writing sheet and a light source. The writing sheet includes a generally transparent substrate sheet or film, phosphorescent paint, and a generally transparent covering sheet or film. To create the writing sheet, a thin layer of the phosphorescent paint is deposited onto the inner surface of the substrate. When the paint is dry, the covering sheet is positioned above the paint layer. The layers are then laminated to adhere the substrate layer to the covering layer with the paint enclosed between them to form the transparent or translucent writing sheet. To use, the light source is run along either the front or back outer surface to create a track, which triggers the phosphorescent paint to luminesce to create glowing traces along the track of the light source.
