Color Seperation in PDf Files: wrong

[gottwavo]

Hi,

I am producing a two color business card in XaraXtreme Pro, but had similar problems with other kind of documents before. This is the situation:

The business card has a logo using a spot color Pantone something. The text is black. I have "colored" the logo in 100% Cyan and the printer will use the right ink to get the right color.

When I produce a PDF file from my Xara document either with Xara itself or with distiller, the color separation does not work as expected and consequently the print will fail.

When I check the single plates with Acrobat (I have Version 7, but I had the same problem with older versions) I see this:

- the Cyan plate shoes black as well, so do the other color plates, they should show nothing and the Cayn plate should show the logo only
- the black plate shows black, fine.

Is there a trick I don not know?
What do you all do out there in such a case?
Change to an other software from Adobe or Corel?

Any quick help is appreciated.
