In your subjective opinion.   Lots of other people DON'T like the way 
BO printing handles contrast.

AH-HA!!

That's your problem.   As I said, do the math.  The problem with BO 
printing is that it can only represent "a few shades of gray".   In 
other words, as I described above, it doesn't have enough tonal 
resolution to represent every possible shade of gray in your image.
