Digital BW, The Print

Grady,
 
I don't know, too. Yet I think that you need some workflow to print with
quads, whatever the ink position is. I made this very simple experiment: I
created an image in Photoshop with three patches of 100% Cyan, 100% Magenta
and 100% Yellow (image in CMYK mode), and then changed the mode to
grayscale. Now Cyan reads 41% gray, Magenta 55% gray and Yellow 7% gray. I
don't know how the Epson driver mixes CMYK inks in order to get different
shades of gray, and I don't know if these inks are 100% C, M and Y, either,
yet I can't think of an easy way to match 7% to 25%, 41% to 50% and 55% to
75%. Remember that it's not enough to have an acceptable print, what we're
after is a close as possible match between monitor and print (and you also
have the advantage of less visible dots if you separate inks).
 
Regards,
Alessandro Pardi

Grady,

I have no idea. Perhaps some of the people who have been at this 
longer have an explaination. The only think that occures to me is 
that they may have wanted to be sure that the lighter grey inks 
always fell on top of the darker ones but this is a shot in the dark.
