Oh, I've read the comment already, of course.  I wouldn't post without
at least having skimmed the code and a comment that long is pretty hard to
miss.

Knew that, too.  It would be an incredible feat of engineering to get them
spaced that closely.  I think it's pretty incredible as it is, with only
1/6th that density.

I could've told you that, too.  You can see it clearly in the ghostscript
uniprint stc740*.upp files.


The thing is that I just can't quite get unprint to unprint the the
softweave correctly.  I'd adjusted the parsing of multi-line raster data
to print every 6th/8th row, and that, AFAICT, is really all that's needed
for unprint to understand softweave data, but, it comes out such that
1/6th of the lines are printed to 6 times and 5/6ths not at all.  (not quite,
but almost)  It seemed like something was off somewhere in the head motion.

I don't know.  I guess I'll just try playing with it some more and try
printing as the EX or one of the other older models.
