If what worries you is the  background reflections in the letters, you could
try to put a  white plane behind the letters with the keyword no_reflection
so it doesn't reflects in the letters

plane{-z, 100 // or any orientation or distance you want
texture{
            pigment{color rgb 1}
            finish{ambient 1 diffuse 0}// not light-dependant
            }
no_reflection
}

Another way is to choose an output file format that supports alpha channel
( transparency channel) and put  +UA in your command line (or "Output_Alpha=
on" in your .ini file)
TGA and PNG support alpha channel.
render with a black background.
Then you can paste your output file including alpha channel on a white
background in an image editing software

Hope that helps

Marc
