Digital BW, The Print

In my opinion, a RIP with really good ink control is the only way to 
print, at least until Epson allows us to adjust the limits and 
linearization through the firmware. The cave paints may work fairly 
well, people seem to be happy with them in 1280 up to 7600 printers. I 
can't say as I've heard from too many people using them in the larger 
printers though. If your machine has upgraded firmware to use the UC 
inks, then I would say that several of them UC replacements would work. 
It's also possible that the heads in the 10K are designed very much 
like the UC heads, and it might work well for you. If you have firmware 
for the Archival pigment inks, then I would suggest the GP Archival 
type inks. This is all based on my printer, which I'm beginning to 
think has an abnormally high ink output. These new inks have a huge 
pigment load for my printer, one of the colors cuts out at 37% for 
correct limiting. Going to send an email off to the manufacturer today 
and see what they think.
