[Scribus] pdf printing problem

[Wayne]

I run ads in two of our daily newspapers for our 
production and I use Scribus to create the pdf files. 
I've been doing this for the past several years. 
Recently, I submitted 2 ads, one in black & white to 
one newspaper and a spot color ad to another paper. The 
black & white ad printed fine but the one with spot 
color shifted two of the letter "A"s in the ad. This 
shift was  enough to cause one word to be illegible.

The production person said that the pdf file looked 
good before the print but came out mangled after the 
print and that there was no way that they could fix it. 
I asked if his software was the current version and he 
said it was. He tried to find out what was causing it 
but could not do it.
His suggestion was that I use InDesign or Quark. I 
previewed the files on Acrobat Reader and they both 
looked fine.

My question is this: Is the problem on my side (Scribus 
1.3.3.10cvs) or his? Has anyone else experienced this 
kind of problem?

The black and white ad, which was virtually identical 
(except without the spot color) to the color one 
printed fine at a different newspaper. I embedded all 
fonts in the pdf files.
