Oh, I see. Separation of PostScript is not a quite easy issue. And I 
think, there are some problems in the use of setcustomcolor and 
customcolorimage in the original xpdf code. As far as I remember, a 
collegue of mine gave me some hints in 2007 and I uploaded a patch to 
xpdf to make ps output separable which was never inserted. But because 
PostScript is not my favorite subject, I didn't care. If You're 
interested, I can look if I can find it again, adapt it to the actual 
code and we can work together to get it running.

Cheers,
Thomas
