I've done everything recommended by you fellow list members and there are
some observations. I finally did find the 'precal' section of photocal
which is when you lie to the program and say you have individually
adjustable guns. There has been a thread about this and sony monitors on
the epson-leben list.
It seems like there are an infinite number of combinations of contrast and
white balance that will give you a screen luminance between 85-95 and a gun
differential less that 0.5. I can't remember the units. But each 10k
adjustment in the white balance produces a very different screen image. i
think to get it where I have it now, and it looks a little magenta now,
(very subjective) I ended up at 6640k and about 83% of max contrast. My
luminance was 90 and variance 0.4. Should I go for the best compromise
nearest 6500k, or go for the best numbers overall?
In addition, when I go back in the monitors control panel and select my old
profile, it does not look the same as as before the calibration. Again,
subjective impression. Does the calibration do something to the guns or the
luts such that they cannot reproduce old profiles, or is this an alias
problem in colorsync, pointing to the wrong profile? I'm pretty sure its
not an alias problem though.
When the rubber meets the road, on my old profile, the monitor was very
close to the output of my 1160 on premQglossy using the glossy film setting
in profiles and glossy setting in media. The archmat also looks good on its
respective settings. On the new profile, I'll have to do some more printing
and looking to know. Overall the difference between the two profiles seems
to be in the green magenta bias.
Someone on the epson list suggested I create a grey-scale gradient in ps and
look at it on screen. There were alternating magenta and green 'bands' in
the 3/4 tone-midtone. I did not know what to make of it.
sorry to be so long winded.
