Hello all, BikerJim here again.
I received such a great answer to my last question I thought I'd try another question. The trouble is I'm not even sure what the question is! But I'll try asking anyway. 
Lets say I build a profile for HP Advanced Photo Paper Glossy. Now what am I looking for in my print and/or screen to tell if it is better or worst than the canned HP Glossy profile. They look different, one is slightly more saturated than than the other. How do I tell if one is better than the other. What am I looking for in my new profile? When I softproof the image I can change the saturation to match the other profile. If it appears that I'm very confused, then appearances are right!

Thanks, Jim
