True, it would only change the pixels from 0 and 1 to 0 and 255.

I think the issue must be resampling. I don't think Scribus will
resample unless told so (setting the maximum DPI), so the resampling
(or anti-aliasing?) might take place during print.

A good way to test is probably to view the PDF on screen and zoom in
(400-800% zoom).
