This is only a "mathematical" conversion. Recent ImageMagick versions which
have been compiled properly (that is with lcms) do much better with
convert RGB.tiff -profile RGB.icc -profile CMYK.icc CMYK.tiff
with RGB.icc and CMYK.icc being appropriate profiles (e.g Adobe RGB and
EuroscaleCoated). ImageMagick is available for Windows, too.
