PURPOSE: If we make light in a sign permeate regularly, as the color distinction of the whole sign, and the characters or figures of the sign improves, the efficiency with the use of the sign becomes high. By carving the characters and figures on the sign in relief, we can discriminate the sign easily, the manufacturing process becomes simple, and the cost to make the sign is reduced. CONSTITUTION: A flange is stuck on the fringe of the board for a sign. After sticking the flange, on the surface of the board characters or figures are carved in relief so that they protrude from the board. A sheet having the color which a user wants is cut in the same size with the characters or figures formed on th relief part. The cut sheet is adhered to eh characters or figures of the relief part by a bonding agent, so fixed to them.
