If you're getting too much magenta: that implies you're not building,
creating, or using the profiles properly.

Usually, a printer will have a green cast when it's running
uncalibrated. The profile will compensate for this by adjusting
the image more towards magenta when you make the print. The two
effects (uncalibrated green cast from the printer, plus magenta
cast coming from the profile to offset this) cancel each other out.

Magenta cast in your PRINTS through the profile implies that when
you're printing, your driver is not running with color management
turned off. So you get the profile adjustment, without the
uncalibrated driver to balance it off, and the result is a magenta
print.
