The same with me, I do not have problems with the color - it is really more that the prints are a bit to dark.
I own the colormunki and I will give the 100 setting a try. Right now I use a print-filter that is lifting the brightness a bit.
I was also thinking about sending a few images to a professional photo lab to see the result and then being able to check if it is the printer or the monitor...
Best Regards,
