Thanks for your replies. Probably the best thing to do is to re-measure the patches or to tweak the current profile. 

The current profile is not bad. When used to print a standard printer evaluation image, with out comparing to a soft proofed screen version, the colors look normal. However when compared to the screen version the colors including the neutrals are warmer. This is more noticeable with images that have lots of browns/tans. I have always found it difficult to get a good screen match of these colors whether printing on my Epson 7900 or 3800.

My monitor is calibrated using the Spyder3Pro. I am not sure how I could incorrectly perform the spectro's white calibration, since this is such a simple straightforward step. Also, I am very careful when I do the measurement readings.

I wonder if the new Spyder3Print SR Spectrocolorimeter is more accurate than my unit?

Thanks for your help,

Ken
