Sorry about the delay in getting back to you; I thought I'd already 
responded.

I'm not sure if that was the right thing to use, but in the end, I don't 
think it would have mattered.

IIRC Ubuntu 12.04 doesn't have an ICC-managed printing stack, so I don't 
think it's Ubuntu specifically screwing things up here.

I'm guessing we're going to need to implement some sort of color curve 
for the Mitsubishi printers inside of Gutenprint.  Right now it's 
linear, and that's clearly no good.  The complication is figuring out 
what the curve should be, and that's going to require a fair amount of 
trial and error, preferably with a coloriometer.

At this point I'm not sure where to go next.  I'm trying to get my hands 
on a D70/D707/K60, but that's not likely to happen anytime soon.

Oh, one other question -- When you printed, did you select matte finish?  
If you did, can you repeat it without it and tell me if the printer 
generated a glossy print?

Thanks,

 - Solomon
