This was of course rather not meant as a final, exact solution, but rather as a quick and dirty hack, based on your assumption that most of your color spaces are similar to ISOcoated. Eventually the above procedure results in printing a proof for ISOcoated on your printer, which uses not absolute, but perceptual intent for proofing (so that the ISOcoated gamut will be remapped to your printer's gamut; in particular the netural axis will be stretched or compressed as necessary). I.e. the transformation behind the scenes is eventually source color space -> perceptual -> ISOcoated -> perceptual -> your printer Regards, Gerhard
