I don't think it is a good idea to convert a photo to the colour space
of the printing machine. These profiles should be used for soft proofing
only and this has nothing to do with the workspace colour profile (these
must not and mostly do not match the display profile).

For soft proofing you can use the softproof funktion of digikam. At
least in DK 1.9 you can set up a soft proof profile and switch between
soft proof and normal view (in showview).
