It matters, but either of those should work for these particular curves. They were made for Martin, he was using sRGB, so 
they were developed for that. Since Adobe RGB is the same gamma, and gamut is not an issue for this workflow, it should 
work the same. Just stick to an RGB space with a 2.2 gamma for these curves and all should be well.

They affect things a lot. They put down different amounts of ink and ramp differently to account for the different dot gain of 
those different media. They also remove CMY and bring in K differently, so curves developed for one setting can't be 
counted on to work for others. I don't know if the curves are valid for 2880, Martin told me there was no advantage to that 
setting, and we didn't use it making the curves. Just try it if you are interested.

It sounds like all is right, including color space, so I don't know. I don't have OSX here, but I've heard there is no way to turn 
off color management, someone elses words and advice so I'm not sure what to make of that. You might try printing out of 
classic to double check. Beyond that, if no one else experiences the problem, it's specific to your printer and current ink or 
paper. Solving that would require tweaking the curves.

you got that one already, good catch
