Hello Ben,
When I asked if your booth was dimmable I was thinking on your Kino Flo, not in a Solux. Kino Flo uses fluorescent bulbs that may be dimmed without changing ( I think ) the color temperature . That is not true for incandescent bulbs likeSolux. If your Kino is not electronically dimmable you may still adjust the intensity of the light that hits the proof by means of a neutral filter ( a dangerous way since "neutral" filters may be not neutral for the color temp. of your bulb ) , using black tape around the bulbs or adjusting the distance from the fixture to the proofs among other possibilities. I'm not sure that Kino lamps, although optimized for shooting are good for softproofing . There are better bulbs for this, like JustNormlicht or GTI. They, both, make lighting booths ( dimmable or not ) but their products although excellents, are a bit expensive for me, so I bought their bulbs ( D50 ) and make my own with
electronic dimmable ballasts from Philips orOsram .

Is you lighting booth dimmable and strong enough to compare to your screen when the screen is adjusted to 80( or max. 100 ) Cpsm ? In my opinion with a proper setup a white document soft proofed with a good QTR profile ( checking Perceptual with BPC and Paper White and Black Ink ) using a good monitor profile ( gamma 2.2, 80 Csm, white point of your booth, 5500 K in this case, if the bulbs are good ) must match the paper used when you adjust the booth ( not the screen ) for the same intensity of your screen . The color of the paper and it's luminosity will be well represented .

>>>I made up a linearized printing
curve in QTR, customized to my printer and custom inks. Then I converted this profile to an icc profile. I can use this icc profile in Photoshop or in Eizo Colornavigator to emulate the printing environment. The problem is that the screen is too bright and the paper is very low contrast (matte). So, it doesn't make sense to use soft proofing if the screen contrast is 4 to 5 times higher then the paper I am printing on. That's why I wanted to find out the best screen settings to come close to the paper's specifications (white point, contrast, etc..).

>>>
>>>Our monitor is an RGB device. The white point we set is a hardware white point that is intended to match a viewing spectrum in this case 5500K .. ..The key here is to realize that when you view B&W on your monitor your monitor is emulating it using RGB technology.. In my mind when you drive the white point to a setting that you feel matches your paper white your throwing a wrench into the works.. The proof of this would be to use the soft proof process in PS which now would not work properly.. It seems your trying to "manually" adjust the monitor to meet a single viewing experience.. Yes you may succeed at achieving the visual for this one particular instance but then wouldn't everything else be incorrect..
>>>
>>>So how about a different path to get there..Maximize your hardware to its design intent setting the white point where it should be for 5500k and them build a great profile for that device.. also required will be a printer profile that you feel delivers the bacon for your printer.. When viewing this in the soft proof process in PS if you feel that it is not representing your visual of the print your looking at.. You could then take your monitor profile make a copy of it (The software I use does this automatically in a profile adjustment module) and adjust that profile to match your visual.. Save that profile then your done..
>>>In my mind if you start screwing around with hardware settings it would be to easy to get lost.. I feel that if you have a proper profile for your monitor and also a proper print profile... these are foundation items that you can stand on and get back to.. If you make a copy of the monitor profile and adjust it your in a better position to get to the other side... also it makes sense if you want to print on a material that has a different paper white..
