Title: Re: 2 questions about monitors
I may have an answer to one of your questions.
We use a 5000 K viewing booth next to our scanning workstation.
The best "match" visually for us is 5500 K on our Apple
Cinema Display (LCD). I'm told this is common and ok to do. The
important thing is that a white sheet of paper in the booth should
look like the "white" on your screen. This should then show
you an image on your screen that will visually match the final printed
piece in your booth (the objective of soft proofing).
I hope your booth is dimmable. The other critical factor in
viewing conditions is that the luminance of each match each other
(booth and monitor, that is).
Sincerely,
Richard

Hi,
I have two questions about monitors - the first one pretty basic, I
have to admit.
First one: Comparing to a printed picture on a 5000K booth, why the
best match is achieved with the monitor set up at 6500K? Theoretically
I don't have to mantain the same color temperature in both?
Second one: Where I find more information about the beforementioned L*
monitor calibration?
Thanks in advance,

I strongly and enthusiastically vouch for the use of L* in monitor
calibration and profiling. I am getting outstanding profiles using L*:
long,
even grayscale gradations with neglectable color seepage, very good
detail
in shadows and highlights, excellent neutrality.
Kudos to Karl Koch for his very good work.
