Greyscale itself cannot be the source of the problem if white is
converted to 0xFF and black is converted to 0.00. Using greyscale makes
the file larger but should not change 'colours' here.

I have the same problem since I use scribus and use colour printers for
output. Are you sure that it happens during the import? I have made
last week a PDF with black and white scans of drawings. Of course, the
scans were either been taken as 1 bit scans or have been converted
afterwards. If I look at the PDF on screen, nothing seems to be wrong
with them. But the print of the same file looks horrible.

I must add here that my part of the work was all done on FreeBSD 10.0
while the print was done on some Windows machine using some Canon

As I never printed these files directly from a FreeBSD machine, I can
only tell that the prints looked since 2007 as you described it. I have
the feeling that the latest prints are the worst ever despite that the
images have been exported with a resolution of 1200dpi. 

With other words, I am not too sure if the fault is on scribus' side.

What experience do others have here?
