I just recently upgraded my XP system to a Vista 64 bit system. I print digital photos using Adobe Lightroom 1.4. With my XP system, I had a good match between my calibrated monitor (NEC 2690) and my printer (HP B9180) working in the ProPhoto RGB color space. I use ICC profiles and let the Lightroom application manage the color. With Vista, I've lost my match. Skin tones look great on my monitor and now print with a red tint. A blue sky prints with a purple cast. I tried Lightroom Beta 2 (64 bit software) but no difference. I played with some advanced settings in Vista's Color Management without success. I'm using NEC's SpectraView II calibration software which is 64 bit compatible. The graphics card that came with the computer is a NVIDIA GeForce 8600 GT. Thanks in advance for any help.
