Once you can measure, the calibrations could greatly improve. If I 
understand correctly you do a basic calibration anyway. The next minor 
step is to create a profile.
I'd like to add, as hardware I thought of a automatic xy chart table.
Such device allowes to place the printed, dry chart on the table, tell 
about start and end points and continue with other things until the 
measurements are finished.

Yes of course should experts be able to create own profiles. I think 
about good defaults. It is much expected to print in sRGB or apply the 
necessary conversions. Without any knowledge about the printer 
characteristic in the driver, this is complete nonsense.

You already tried to keep the colour rendering stable or inform about it. 
Thats a good direction.
The next step of colour support could be to provide conversion or 
reversive profiles after changing the drivers colouring. This would help 
in using older profiles for newer drivers. The profiles must not at all be 
ICC, but a somehow documented format with the according values.


I am still working on the device settings in ICC profile side. Then we 
should agree about a way to communicate calibration states and influence 
them in a hopefully generic way. This should be the time where installing 
of ICC profiles would become much easier with the appropriate 
applications. To promise not too much, decission would still be needed to 
match the paper and possibly inksets and walk to the right web site for 
the downloads.
