I am still experimenting/playing with printer profiles
using not-so-good (= cheapish) paper qualities.
How on earth do I produce a good profile for a printer that has
CcMmYK inks? Argyll can not handle a 6-color printer (or is there
something that I have not understood?).

I used a commercial provider. They sent me the files (sample charts), I printed them (all colour management off), posted them off, and they analysed them with their (hopefully) good quality scanner hardware. Then they sent the profile by email. Cost was around £15. Of course it’s only for one printer / ink / paper combo.
It’s do-able, but ArgyllCMS is missing some of the tools you will need. You need to create a (device link) separation that converts CMYK to CcMmYK. For light inks typically a couple of curves suffices.
Gaps in the ArgyllCMS tool chain:
- Creating separation curves with tuneable overlap between the curves
- Converting curves into a device link separation.
- Applying separation during test chart printing
- Applying separation ink limits during profile creation
- Combining CMYK device profile and separation into an N-channel device profile.
But you would also need to confirm your printer driver workflow. i.e. can you
- print N channel test charts ? If so, using what format and conventions (i.e. PS, TIFF, details ??)
- Does your print driver handle N-Color ICC device profiles ?
(We used ArgyllCMS extensively for creating profiles for light ink printers at ColorBus, but the
separation curves were part of the printing system/drivers, not part of the ICC workflow.)
