Digital BW, The Print

Yes, I agree with you and Clayton's comments. I should have 
originally specified color casts as opposed to metamerism issues.   
The custom profiles do remove color casts.  Concerning metamerism the 
4000 prints in daylight and a light box (5000 K I believe) showed 
little difernce with my eyeballs so it's subjective.  And, thats  
what I like about the option of using both methods, you can alway's 
fully eliminate metamerism with BO.
