Andy, thanks. I am aware of Digital Dog site - lots of terrific helpful information.
I use the papers ICC profile when printing. When I soft proff in LR I use the paper profile. and L L Out to view the print against a white background.
I am familiar with the LAB values and use them. I do not use the Print Adjustment in LR.
Unfortunately, I no longer have my NEC PA 272, am now using a recent iMac w/retina display. Values are set to cd/m^2.
Light source is a problem when viewing prints as you mentioned. I will dig into the issue some more. Interestingly, this problem ocurrs on my older, 2009 images as opposed to more recent shots. Different camera now - and - these images were processed in Aperture!
thanks for your thoughts.
