[Gimp-user] Color Separations

[The Bold Look]

Hi there… I’ve been playing with the Gimp for the last couple of weeks and I found it an amazing tool, however when I tried to output my designs to my postscript printer I found that I can’t setup screen angle for the printing, which I need for my business (screenprinting)… does anyone knows how to accomplish this within the gimp?. I googled but couldn’t really find anything.
