Sounds like a good start.  If you want to investigate better RGB <-> CMYK
conversion, then the littlecms library is a good choice to do the heavy

profiles.


Yes, great library and easy to use.



A default conversion from sRGB to SWOP-Coated seems to be the combination most
houses use when no "proper" profiles are available,

SWOP is fine for US, but Europe, Japan, etc. use different - so you give folks the choice...



and will generally give
considerably better results than a [c,m,y]=1-[r,g,b] type algorithm...

MUCH better...


There are also some better algorithms for conversion as well.
