Digital BW, The Print

One of the major problems with any Epson printer --including the 
4000 -- that uses UltraChrome ink is with the ink itself. The 
metamerism in the yellow ink makes UltraChrome ink unusable for a 
print for sale in my opinion (unless some work-around is employed 
like the ImagePrint RIP which doesn't use the yellow ink, I 
understand, for B&W prints). I know its off topic, but these printers 
aren't cheap and when you look at the same Ultrachrome flesh tones in 
incandescent light vs. daylight its startling. No excuse for this in 
a $3000 7600 or an $1800 4000, and for what Epson is charging for 
their ink.

The other major problem with the 7600 is with swapping out photo 
black for matte black or the other way around. I do this all the time 
in my 2200, but this would go through $100 of ink a pop in the 7600 --
 again, no excuse. This, fortunately, has been addressed in the 4000 
with its extra ink position. 

Both these issues are showstoppers on the 7600 for me, and the 
UltraChrome ink is a showstopper for me on the 4000. Epson needs a 
new generation of inks that address metamerism issues.
