That was easy, when I commented away #1, I got the regular b/w
positive image that I wanted all along.
So.
It seem the cm-calibration plays a role in this. Of course, I
understand that it could be a good thing to have it true, but does
that mean that I should do some sort of color calibration of my
printer (which, I'll remind you, is a b/w laser printer, and with
pretty few levels of grey to boot...)? How do I do that?
(Yup, I'm ready to try that, if there's a way)
Cheers,
Richard
