Gradient disappears when postscript from Indesign CS3

[Conni...@adobeforums.com]

Hi there, I am using a OSX 10.4.11 on a mac. I have made a gradient using 2 spot colours (metallic 8920 copper and and 8602 silver) and a transparency of 50%. When I postscript it using postcript file and prinery refiner ppd and then distill it to pdf I lose the bottom gradient (being the silver colour) it just turns to white. When I open it in Acrobat it has created 2 boxes - the one on top has the copper gradient going to white and when I delete this the silver is sitting underneath it in its own box going from silver to white. I have exported it as an eps and it seems to hold the transparency but I am reading threads where it says that eps's don't handle live transparency. Can anyone help as to what is going on - I am very new at this tranparency stuff and it tends to confuse me a bit at the moment.

Thanks in advance for your help.
