Abstract (en)
[origin: WO9843229A1] The invention relates to a method for manufacturing traffic sign boards reflecting back light (L) and including sign figures. In the method a light-retroreflective layer (2) is attached on the base material (3), and colour materials (7) forming the sign figures are arranged on the outer surface of the layer. In accordance with the invention, the light-retroreflective layer is arranged uniformly over the entire traffic sign figure area so that it does not substantially change the colour of the reflected light. The necessary sign figures are arranged on one side of a separate coating film (4) in mirror image. The coating film is then adhered onto a retroreflective layer on the base material so that the reversed sign figures face the retroreflective layer. Thus, the sign figures consisting of colour materials are between the retroreflective layer (2) and the coating film (4) and protected from detrimental effects of the environment.
