To Edmund's point, I would add: is there any reason why an OEM driver could not include ink-limiting and linearization utilities?

As long as it isn't a CMYK driver (or a 12c driver) there are very compelling reasons and many of them.


Why would it be so hard to implement there?

Because it takes a lot of work figuring out where to fade down one ink and start using another - think whi to fade a light magenta and yellow to a red to a black. HP spend the better part of a year working on this and improvements are still emerging. If you start limiting certain colors you would screw up this carefully balanced act.


Or is it just that the printer companies don't see enough of a Return On Investment to justify the necessary R&D?

I think the main issue would be usability. Adding in functions only a very small fraction of users would be able to comprehend and all the others burn their fingers on (think back to color management in PS 5 for a short while) doesn't make much sense from a commercial point of view.


If you want inklimiting you have to go advanced and get a CMYK driver (often postscript is just an added bonus) for the simple reason that you send a different stream of data to the printer - CMYK as opposed to RGB in quickdraw/GDI.

That would be hard to comprehend, because HP, for example, spent lots of time and man-hours to develop the Z3100 in Barcelona. Spain, going as far as to put a spectrophotometer in it, only to stop, if I'm not mistaken, and not go that extra tenth of a mile to include ink limiting (though there is a linearization-like calibration procedure of sorts, from what I read).

It's not an extra tenth of a mile but an extra half marathon that very few poeple would need/expect in a "basic" driver-
