Using SpyderrPrint v 3.5b9 I created a profile of Museo Portfolio Rag
printed on my Epson 3800 using the high quality target plus gray. 

After tweaking the shadow detail slider to open up the shadows in the
print plus adjusting the reference black to improve the soft proofing
in Photoshop, I am happy with the print quality the new profile provides. 

Soft proofing in Photoshop looks good except that the soft proof clips
the highlights. The actual print has nice highlight gradation, but the
soft proof clips a couple of steps off the scale. In the soft proof,
step 250 is the last step to show separation from pure white. On the
print, step 252 is the last step to show separation from pure white,
so the soft proof clips a couple of steps. I am not sure how to
correct the soft proof so that it shows the the actual print's fuller
highlight detail. 

Any suggestions on how to tweak the soft proof highlight detail? I am
using the Printer Evaluation Image available at outbackprint.com.
