No, that's incorrect.
I use an Apple Cinema Display 23" monitor which has been calibrated
to white point 5500K and gamma 1.8 with a Gretag-Macbeth Eye One
Display 2 unit. It's what I do all my serious image processing and
printing from, and is extraordinarily consistent with what I see
coming out of the Epson R2400 with a full a color managed workflow.
I'm using Apple's Safari browser as well, which is fully color
managed and honors embedded profiles when available. On this setup
configuration, the grayscale blend and step wedges shown on
http://homepage.mac.com/ramarren/calibration/cal.html
are fully expressed and neutral in color. Printed, they render
*exactly* what my screen displays.
