Roger, I agree with you that the ICC process should not be limited to one
perspective. I believe the poster feels the same. However, if we want to
have our profiles work in the real world realm of color output, we have to
get serious about inkjet. With Donnelly developing its own 1200 dpi inkjet
web presses, and HP's expressed intention of replacing all electrostatic
(laser printers and copiers) with high speed, wide pass inkjets, and on the
horizon, two-D matrix inkjet heads that can blast a full color page 200
times per minute at desktop prices, it appears to me that most of the color
output devices of the future will be inkjet. Electrostatic is going away
gradually and will accelerate soon. So let's not keep our heads in the sand
- color management has more to do with generating good real world color than
academic equations about transforms. If we have customers, results are what
count - not how we get there.

Inkjet printing is a rough process. The case you cite, Mark, those EcoUltra
is a prime example. I agree with you that the business of setting ink limits
on anykind of inkjet device is key for the subsequent success of color
management. But I am not sure I agree completely with the opinion of the
poster when he writes that the ICC should do more to help smoothen out ink
limiting. But that's me. Otherwise, in my view, to be fair, the ICC would
have to speak to all kinds of color reproduction process, not only inkjet
but also laser, dye sub, photographic and who knows. And get involved at the
"driver" levels for all these devices to do a complete job. And I'm afraid,
then, that it wouldn't take long for the ICC to get bogged down in all the
nitty gritty of those processes that, frankly, the whole color side of the
ICC work would come to a halt. To me, Mark, it would deter too much from its
core mandate which remains, IMO, to model color transforms between devices
and build processing infrastructure around those transforms for the rest of
us.
