Chocolate is too strong a description, more like slightly magenta 
leaning towards blue.  I ran a K only test strip on my DJ90, using HP 
Prem Plus Glossy thru Imageprint (the three values are L,A,B), read 
in spot mode with my Eye-one Spectro (non-reflective black background 
underneath print):

100%   2.5  .5  -1.9
 90%   4.2  .6  -3.2
 80%   7.4  .7  -4.8
 70%  12.5  .5  -5.2
 60%  19.1  .3  -5.4
 50%  27.8  .0  -5.4
 40%  36.9 -.1  -5.2
 30%  48.2 -.3  -4.9
 20%  61.3 -.4  -4.5
 10%  76.8 -.5  -3.8
  0%  93.7 -.7  -3.3

Of course, at 0% I'm measuring paper only.  I will agree the "tint" 
is small enough so that using only K will result in a nice B&W, 
assuming a satisfactory dither pattern.
