Carl,

I haven't done exhaustive tests with the 2200. From looking at my grayscales 
and discussing with Robert, I expect that on glossy papers highlights will be 
dotty, especially if only the black and gray is used.  Papers like Hahnemuehle 
German Etching hide the dots quite a bit.

 In that respect, the realities of the hardware are the same regardless of 
software. I personally have an aversion to seing little bright dots of color in the 
highlights, but I guess one could bring in Light Cyan or L.Magenta as a way to 
blend out the dots. Better yet... use the MIS Ultratones when they become 
"official" and blend out the dots with gray.  The 2200 has a significant 
advantage over previous generation machines in putting down finer dots, but I 
think it still needs one more gray to match a 4 ink grayscale.

As for crossover, it is not an issue because of the way profiles are built in IJC.  
Unlike ICC-based complex calculations for maintaining the gray axis and 
dealing with color temperature and the like, here you have a simple curve for 
each of  the color inks you wish to use.  You simply put more or less color in 
parts of the gray scale as you wish.  In fact, you can see the curves for all 
active inks at the same time and decide how your color inks relate to the gray 
ones. It's more a matter of user- choice than an accidental result of internal 
calculations of a color profile making app.
