If you realy don't want any shadow, remove ALL light and set ambient 1 
in the finish, but it will look flat.
You can keep your light(s) and add "no_shadow" to your ribon. It supress 
the casting of shadow and you keep the angle dependent lighting. Bind 
the whole ribon in an union and add the no_shadow to the whole thing.
