    HDR monitor for printing?.
    on: October 30, 2023 at 2:34 pm

    Also, when it comes to monitors and printers… they are two different technologies for reproducing color.  As such they have vastly different gamuts.  Attached is an illustration of a luster profile on a P900 poking out of an AdobeRGB gamut.  (The Eizo 2700S can hit approximately 99% of the AdobeRGB space.)  There are colors the monitor can produce that the printer cannot – and surprisingly it is true the other way around also.P900

    That is kinda old for a colorimeter.  They usually have plastic filters that get brittle over time.

    But really, the first thing to do is try the calibration again.  Sometimes weird things happen with computer and instruments.

    The control of the panel that Andrew was referring to can best be thought of as a built-in graphics card.  These high end monitors, especially those with an extended gamut, make use of built-in graphic processing that is better than what’s built into the computer – so that you get 1024 points of “adjustment” of color – a more precise adjustment than what is available with most 8-bit graphics cards (256) that are in your computer.   Each manufacturer (NEC, Eizo) makes available its own software that can calibrate while talking to this built-in graphics card.     You obviously don’t want to calibrate these high end monitors without using software that will work with these advanced graphic processors.   basICColor Display is an independent software which supports many of these displays.  It might not support every NEC or every Eizo –  so do check to see if your model is supported.

    My, it sounds like you are doing everything right.  Here are a few ideas off the top of my head that you could look into:
    – The different backlit technologies could affect the way the instrument measures the white.  If the iMac is consistently too bright, choose a lower luminance to calibrate it to, like 80 cd/m2 and calibrate only the iMac to that.   See if this makes a difference.   You would probably have to open up a blank white page on both displays to visually compare them to see which setting gets your iMac to where you want it.
    – When calibrating monitors we preferably like to have them roughly set up mechanically before we ask the software to step in and fine-tune the color.  I’m not sure if your iMac has a way to consistently reduce the backlight of the display before calibration?
    – Does the i1Profiler ADC feature (Automatic Display Control) interact with the iMac? (I’m not sure if it does or not.)  Are you using that?  If it works, it would take over the job of interacting with the hardware to control the display backlight.

    I am drooling with color geek envy!  That Kodak Custom Color Tools plug-in was amazingly simple and effective.  But, yeah.  We would not really have that much use for it these days.
