So I've had my NEC PA 301W monitor for 10-15 yrs. I've calibrated it for years with the xrite Spectra Sensor Pro and Spectraview II that came with the monitor. I print on 5 yr old Canon IPF 8400. I use Photoshop CC to process. I used a Canon for years but now shoot with a Fujifilfm 100S with Fuji GFX lenses. I'm not a pro so I don't use the monitor 24/7 but I have used it a lot over the years. Not sure how many hours or if there is a way to check the hours on the monitor. I'd say I'm somewhere around an advanced amateur level of photographer. I've been calibrating monthly over the past 6 months using the following settings in a moderately darkened room: White point: D50, Gama 2.2, Intensity 90 cd/m2, Contrast 200:1, Color gamut Native.
I process in photoshop till I get what I like on screen. Use factory profiles for printing. My problem is that now the print is always significantly overall darker than what is on the monitor. I usually have to go back and use curves to lighten up what I'm seeing on the monitor to where it's almost too bright on the monitor in order to get the print to come out at a reasonable brightness. The darkness with the first print is most notable in the darker areas of the picture where color and detail are being lost, but it is also darker overall than what is on the monitor. I've noticed this problem for years but it seems it's getting worse.
So I'm not sure if I have the calibration settings wrong? Or is my monitor and/or xrite sensor getting too old to reproduce brightness accurately? Any thoughts or suggestions?
