Thanks Pierre!

Yes, you are right. I should of course have typed 'rasterized' or: 'not 
full black'

Sounds strange but could not think of another non-proprietary way to 
check the color of the font after converting the .sla to .pdf -- the 
font is 100% CMYK black when we check the .sla in Scribus; when 
re-opening the pdf in Scribus (1.3.4) it crashes ;-)

I'm trying to find the similar mention in 
  (the test file that seems to come up correct) to understand what you 
mean / to see the difference. Which tool are you using to look at the

I understant it is normal when black is not defined as CMYK (but it is). 
and sorry, only now I find back this thread:
http://lists.scribus.net/pipermail/scribus/2007-July/024349.html plus 
many discussions on color management but I'm a bit lost.

Scribus is compiled with littlecms support but color management settings 
do not show up in preferences (I'm not too interested for this 
straightforward black and white job). Maybe that's why pdf's come out 
correctly now?

Yes, which I understand if we had decided to choose a 99% gray / RGB 
black for text. But we did not

Still a bit puzzled
