Actually, the above is incorrect. A color file that is in 8-bit rgb
mode converted to BW only has 256 tones (levels) even if still in rgb
mode. This is because all three of the rgb values become the same for
each pixel (r = b = g in that scenario).

Clayton, yes I do believe that posterization and histogram combing are
diretly related to one another. Also Clayton, I sent you a direct
email with questions about a replacement for Epson enhanced matte
(Kayenta?) yesterday. Maybe it went to your spam folder?
