Thank you, Daniel
It's been pointed out to me out to me, that Graeme was referring to the
difference between 8 bit vs. 12 bit. So I must assume that he means anything
above 12 bits is superfluous and that I would see the same difference
between 8 bit and 12 bit that I see between 8 bit and 16 bit printing. As I
really have no intention of doing the old 8 bit vs.16 bit scenario, I
apologize for misunderstanding.
