Don’t know why. No room for either a small Fluorescent booth or one Solux task lamp?
Well, yes, but I still don't have a "print" as such to match. I do get to see the final result, but usually days or weeks later. That said, the result is nearly always spot on with the "paper white/contrast ratio" strategy. I usually know the type of paper in advance.
I'm sure the "up the print viewing conditions"-strategy will work perfectly well as long as you control the entire process in a closed loop - IOW you print the file yourself. But instinctively I don't see how I could work with luminance in the 150 range - for that to work I'd have to raise the overall ambient light to a very uncomfortable level. I need to visualize on screen what the result will look like under "average" conditions, and for that 100 -110 cd is fine where I sit.
It's true that many monitors perform poorly below 120 cd or so. But I'm sure the NEC PAs can handle down to well below 100. Eizo in fact defaults to 80 with the CG/CX, but I really don't see what they're getting at there. That has to be way too low for anything but a very dark room. Maybe it's just a holdover from CRT.
