Digital BW, The Print

I was already down the road to getting demo, but I am using 3rd 
party (MIS) pigments in a 1290 for colour work and UTs in a second 
1290 for B&W.  Therefore the demo was not much use. 
What if you converted a greyscale file to RGB and printed it with a 
colour profile - then compared it with the same file printed in 
greyscale with the B&W profile - REALLY any difference?? Would love 
to know - this is basically what I was getting at in the first post -
 does RGB work for B&W ouptut with IP - what real differences / 
losses are there?

I agree with Paul aswell, can't wait to see what is made of the 
4000!!
Thanks again

Steve

print the color when it "sees" it? I know it would if a color paper 
profile is selected--and I suspect the gray portions would print as 
gray--but, then you would have metamerism, etc.

print "DEMO" all over the image in large letters, which is kind of a 
pain, but an evaluation of the print is still possible.
