Digital BW, The Print

My driver, for Windows, and with MK loaded in the printer does not have 
a BO (or three-black) mode available.  The options are "Color 
Controls," "Photo Enhance" (there's a scary thought), ABW or "ICM."  
There is also no BO within any of those selections.

What the latest version of the Epson driver (5.52 as of 8/22) does 
offer is a much more complex ICM setup.  It essentially provides the 
capabilities of PS color management:  ICM Mode (Basic or Advanced, the 
latter providing a very complex range of settings), Input Profile, 
Intent, and Printer Profile.  The Input and Printer selections offer 
all the ICC profiles in the Color folder (Windows).  So, if you use PS 
(and anyone who didn't wouldn't know what this new stuff was all about 
anyway), I don't think this adds much to the mix.  One thought, at 
least possible, is that letting the printer designers make these 
conversions might provide something that the PS conversions don't.  
Maybe someone else wants to look at all this in more detail.  Epson has 
an odd way of constucting this stuff without really discussing its 
purpose.  Incidentally, on the possibility that it was not clear, if 
you select "No Color Management" in the Epson driver, none of what I 
have discussed is available.
