When I pcl-unprint a CMYK PCL file, the black is "smudged", i.e.
there is unwanted black getting in somewhere. I assumed I had
made a coding mistake.

I've just done some recompiling of pcl-unprint to output either
the CMY part or the K part, and it looks rather like the
problem is not in pcl-unprint, but in dither_cmyk().

I tried with the output of print-2.0.2 and the CMY part
contains no black at all, but in all the 3.x versions back to
20000131, the CMY part contains black smears or shadows (the
K part is fine).

Robert - help!
