[Scribus] duotone or bichrome publications

[Vic Mortelmans]

Hallo,

can scribus handle duotone (bichrome) publications? I'm not a 
professional, but I want to design posters or flyers for a concert and 
out budget is limited to printing 2-colors (black + orange).

For regular drawing entities, I can of course restrict to those colors, 
but it would be far more easy, if I could tell scribus beforehand to 
restrict to specific colors.

What about bitmap elements? Duotone images seem very hard to create. The 
Gimp can't (as far as I figured out searching documenation and the 
inernet). Can scribus help me out for that?

Groeten,

Vic
