[texhax] Using other colors than black in monochrome bitmap pictures

I have a monochrome TIFF picture that, according to a typography manual 
that I try to follow, should be typeset with "6% black". That is, the 
black colour of my monochrome TIFF picture should be light gray.

Converting to a grey-scaled TIFF and then to EPS is obvious, but with 
the drawback that both the TIFF and EPS files grows significantly and 
later processing by GhostScript is slower. I guess this is due to the 
increased color depth that is needed for grey-scaled images.

I guess there must be a better way? Is it possible to specify the two 
colors used by a monochrome TIFF or EPS file? Can it even be handled 
from within LaTeX? Or can I patch the TIFF/EPS file?


PS: Is there a safe way of converting Pantone PMS colors to 
corresponding color.sty colors without having to guess too much? DS
