Sounds like a flaw in your profile logic. The convert to profile route should
give the same result as the printing dialog, given the same source and
printer profiles, and the same intent and CMM. Are you actually tagging the
CMYK image with the Waterproof profile to begin with? Or is there another
profile tagged to it, by chance? Or are you prehaps printing the *proof* not
the original, such that you are applying the profiles twice?

The paper white and ink black check boxes are not for printing, but for the
return tables, for proofing only. So if you want to *print* the tone of your
biege paper and the dull gray of your weak black ink (say on a glossy proof
of something that will be on uncoated stock in the final run) then use
Absolute Colorimetric, and you won't need these boxes. If you wish to print
it *on* the biege uncoated stock (not use ink to simulate that tone), and are
going to get the weak black already, due to the absorbant paper, then you
simply want the Absolute values in the *return* table, which is what the
check boxes give you. This is the first time Photoshop has allowed
asymetrical intents: you can use RelCol or Perceptual to the printer, and
AbCol for the proofing view return table. Gee, almost as good as LinoColor
<G>...
