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. Yours sincerely Tobias Hilbricht
