Digital BW, The Print

Thanks, Clayton
I used your settings and got a beautiful print on EAM. (6x8)
Now I'm going to print a big one! Do you find this BO has size 
limitations based on the dots? 
Have you by any chance compared this method to using  the 
OPM driver(which I am assuming uses more of the Ultrachrome 
inks)? Oh, I think that only works with OS 9 on Mac.
How about color shifting, fading or longevity?
Thanks again for your time and explainations.
