[...] How are you profiling your display, what display profiling parameters are you using, what ambient light do you work with and view prints with?
I profile the display with an I1 Display, D65, 100 cd/m2. Work room is subdued supposedly neutral lighting, walls are beige, no sunlight or other bright lights distracting. Viewing environment is daylight in a studio with north facing windows (the only fussy client has a similar environment).
I think my uncertainty arose just after receiving the P5000 and I had 50 prints to deliver to an exhibit that week. I panicked when I saw how the impressive DMax of the inkset affected the deep shadows (25 of the prints were B&W), and to get the job delivered I made the Print Adjustment. Once that crutch was in place, I never bothered to take the time to analyze what was going on and happily printed without always going through the soft proof adjustment step. *slaps self*
I'm sure now that the printer and Epson profiles are fine, although I believe I will get custom profiles made anyway. Thanks for your help!
