What version of Profile Maker Pro did you start with? I think back 
with version 3 they started to correct automatically for the extra 
blue that shows up on papers with lots of OBA (like EEM). It would be 
very obvious if the software wasn't helping you out, the yellow cast 
is very visible under nearly every lighting condition. If you only 
ever use things like Photo Rag or German Etching, those don't have 
enough to cause problems. Even Innova Photo Fiba may not cause a huge 
problem. But EEM and many of the glossy papers will give you grief 
for your color work.

I really like Printopen, but the out of gamut clipping really puts a 
lot of people off. There's a comment waiting to be said about that, 
but I'll leave it alone. Even the older Printopen 4 works really 
well, at least for CMYK (I don't ever really use the RGB part). I'm 
moving to Monaco Profiler 4.8 for the profiling service, not sure 
exactly what I'm going to use for my printer yet. The one thing about 
Profiler is that I can make a GCR that gives me real world Black Only 
printing through my RIP without having to turn off the other inks. 
That was a real advantage before I could turn off the inks (old Fiery 
RIP). However, Profiler really requires a UV spectro (I now have an 
i1UV, and a Pulse UV in addition to my regular i1, almost time for a 
sale). Before I bought Profiler, I was going to upgrade to the 
Prinect toolbox, Printopen 5 has some really nice new features to 
handle OBA, as well as some new graphing features that would come in 
handy. It's also ICC v4 for the printer profiles, and finally 
supports direct scanning measurement from an i1, I've been using 
Colorport to get around that.

The one thing I like the most about Printopen is the quality of the 
profiles from the tiny 210 patch target. I can print a small 
linearization target on one end of a 8.5x11 sheet, and the 210 target 
on the rest. So with three sheets of each sample I can get a good 
test print put onto the other 2 sheets. Comes in REAL handy when 
doing a large batch of testing. The IT8 and ECI2002 do much better of 
course, but it gives you a good enough idea of what to expect when 
you put a bunch of time into optimizing a set up.

If you have a measuring device that works with Colorport, drop me an 
email and I'll send you a text file to make one of the PO targets. 
You measure, and I'll make, then you can compared directly what they 
look like with your setup. Colorport works with i1, most Xrite 
spectros, and a couple of the other Gretag spectros.
