Ah, now I understand better what you are trying to accomplish John. Makes perfect sense.
I have no experience with the Pro9500 so I was speaking in generalities. Perhaps trial and error by trying various Canon-supplied profiles might be your best alternative.
Of course, you could always have a custom profile made for whatever plain paper you tend to use if you wanted to. If you tend towards obsessive/compulsive (as do I, sadly), then this may be your solution.
