No...use the contrast setting you like to use for color and tone corrections and general imaging work then soft proof using the final output profile. Make sure you use the paper white and black ink and you'll have soft proofing in the dynamic range of the final output.
And seriously, 90? What, you live in a cave? With LCDs that seriously isn't needed nor desirable. Standard is 140 and I run my 3090's at 180. This is because I have carefully elevated the ambient lighting so I no longer need to work in a cave like I did with CRTs...and I have a GTI digital dimmer on my lightbox for viewing so I can match up white point luminosity between soft proof and lightbox.
Thanks for the soft proof info...I'll make sure I've got it set up correctly...
no cave...I started some test calibrations when i received the monitor about three weeks ago...went slowly down from around 140 and my photos, color and tone, look fine to me even at 90...
much of my work till now has been book covers...i've kept my lighting real basic...60 watt overhead bulb, desk lamp behind monitor area...checking color here in varying 'real world' conditions and i've gotten very good matches for color when the final print is done...this has been with the older tube tech for monitors...this is my first quality lcd...
will usually check/verify final color at the printers where their art department takes my files, creates plates, proofs, and then be on press to make sure the color is in the ball park of acceptable to me and client...
however, I'm about to start printing my photos, will use a print studio near home who uses an Epson 9900...he scared me though on my first visit to talk about procedure...I asked if he provided profiles for me so I could soft proof at home...he said no...'bring your file, we'll make some test prints so you know you're color is what you want and then I'll make a final print'...
I'm still gonna try and soft proof my files at home...get as close as i can to what i want and then bring my files to him to maybe 'fine tune'...this printers space did look like a cave to me though...very dim lighting...
there is one other pro level printer I know of not too far from home, I live in a small town...and I'll visit him next week and see what kind of printers he uses, if he'll provide profiles, see how he works...
thanks for your help JS...I will try the Intensity at 140 again...try some new calibrations today...see if i can get better screen results...
