Faded- Loss of colour brilliance due to length of exposure, weather conditions, or technical problem with production.
Flagging- A tear in paper used on the advertising structure, causing the paper to hang loose and "flag".
Flex face Vinyl- One piece vinyl used on billboards, can be computer or hand painted.
