Umm, the colors have to be more blakish for printing, because offset colors 
are a little transparent (they still show the white from the paper). So the 
picture on the left hand side looks like a document intended to be printed 
for me.

Why your Acrobat did not correct the display with the embedded color profiles 
is a mystery to me though. Are you sure your whole workflow is color 
corrected? Can you get a proof from your printer? A proof would be the only 
definitive answer if your colors will look as intended or not (at least as 
far as I know).
