Hello to all,
Some comments at the end.

Michael Vrhel:
Could you please comment, if GhostScript is able to embedd the target 
profile of an ICC based color transformation into the rasterfile handled 
over to rastertogutenprint

If yes, which command has to used for doing this ?

Best regards

I would recommend, that gstoraster embedds the printer profile in the 
raster-file which is handled over to rastertogutenprint and Gutenprint 
checks the incoming raster-file for an embedded profile and than looks 
for the DICT Metadata.
