Hi,
I'd like to read peoples' opinions about using Apple's DigitalColor Meter to
analyze monitor profiles. I'm interested in how similar our group of
monitors are at displaying color. It's one thing to look at a group of
monitors and make a subjective judgment, but to be able to analyze them
objectively would be very useful. Here's a breakdown of our tests:
- Three workstations with NEC 2080UX LDC's were calibrated and profiled with
OptiCal 3.7.5 and ColorVision Spyder.
- A CMYK file was viewed in Photoshop, tagged and soft proofed with paper
white and ink black with a custom press profile.
- On each of the workstations, we used the DigitalColor Meter to read the
RGB and CIELab values of the paper white, 100%k, and 50%k of the Photoshop
file.
- According to each ColorMeter, the RGB's the monitors displayed were
slightly different (which makes sense), and the Lab's were virtually the
same, give or take a few 1/10th's or 1/100th's.
Questions:
- Am I correct in saying that, the CIELab values that the Color Meter is
calculating are derived from the RGB's as viewed through the monitor
profile?
- If so, then are the Lab numbers from the DigitalColor Meters telling me
that the monitors are, in fact, displaying color virtually "by-the-numbers"
the same?
- Would there be any use to using the Tristimulus values to analyze monitors
color in this fashion?
Thanks,
Carl Stawicki
