Yes, that is correct. With the screen luminance set at 120cd/m2, I adjusted the images to my satisfaction. When the prints returned from the lab, they were somewhat darker than the screen image in. After re-calibrating the display to 80 cd/m2 & re-ajusting the images in Lightroom, the returned prints were brighter & a better match to my screen images. Simultaneously, however, the prints were also clearly "warmer" without any changes to the white point. My initial reaction was to increase the white point to cool the color temperature of the prints. However, I think that I recall reading in Andrew's book (or in an X-Rite article written by him) that he recommends that the white point be left at D65. I would value some thoughts on this.

Thank you for your help & your patience.

Warmer, it's the CCT value you need to adjust. There is no 'right value' expect the value that produces a match.
As to the brightness, I'm not sure what your test, adjusting the image based upon a cd/m2 setting does useful. I'd set the cd/m2 value based on the print viewing conditions next to the display:

Thank you, Andrew. Raising the CCT above D65 (my current setting) sounds logical in an effort to reduce the "warmth" of the print compared to the on-screen soft proofed version. My only reservation has been that I vaguely recall that you had advised against changing the CCT value from D65 (the so-called industry standard). But, I might be mistaken.

It's not an “industry standard” there is only one object that can produce this that is 93 million miles away, that is based on the average of many measurements and there is no reason to target such a value if it doesn't provide a match to the print.

I concur, but deferred my decision on re-calibrating based on your input. Color management is not my forte. Now if you want to discuss classic cocktails, I can hold my ground. :-)

Thank you kindly.

Sounds like a PM to me. If that option is available on LuLa, let me know. There is an alternative life after color management.   ;)

Enjoy the evening!
