How to achieve color accuracy...the age-old question.
Good luck with those rich blues. Always a nightmare. Even for professionals that (sort-of) know what they're doing.
If you are using your home printer (or even a print house) I'd suggest printing a page with a bunch of swatches of your rich blue colors that vary differently in shade, saturation, etc. Whichever looks closest to what you want... use that, instead of what your monitor is telling you is correct. Working within the limitations of your ouput unit is sometimes easier / better / more reliable than technology to correct the problem.
You can try to calibrate your monitor with tools, but I've never found them to be accurate enough. You might be able to tweak your settings to work with one printer, but every time you output to a different unit, you'll need to recalibrate to that unit. Some caveats to all of this, of course... it all depends on your budget, equipment, and requirements.
I've always had better luck working against the values from a "known correct" sample, especially when I'm working with rich blues.
