[Inkscape-user] Exported gradients and Adobe Reader 8

Hi all,

Last year, I have used Inkscape to make a nice A0 poster with gradients. I exported the original svg to pdf and sent the file to my favorite printing shop. One year later, when I open the pdf file, I don't see the gradients any more. Of course when I open the svg file with Inkscape 0.45 the gradients are here. So my question is : if I ask them to reprint the file (I don't know what is the application they use) will the gradients be printed ? Is there a problem in the way that Inkscape export the gradients which could be broken by recent versions pdf software ?

Thanks for your help

S.
