[Scribus] Pdf exporting

[s20031701 at tuks.co.za]

I have a pdf problem but its not really a scribus problem.

Our printers rip rejects our pdfs. To start of with, they only take pdf 1.3 
(cmyk) (x-1a) but scribus 1.2(RC and final) pdfs got rejected (and I did export 
it as 1.3) the problem is with a certain command. Their rip's output looks like 
this:
"Subject: Not Available
Author: 
Keywords: 
Creator: Scribus 1.2
Producer: Libpdf for Scribus 1.2
CreationDate: D:20040902103151
ModDate: D:20040902103151
Total time: 3 seconds
%%[ Error: rangecheck; OffendingCommand: Tj(PDF); File: %ip:Spread% ]%%
%%[ Flushing: rest of job (to end of file) will be ignored ]%%
Job Not Completed: test1.pdf"

BUT, i sent them a scribus 1.1.6 pdf and it didnt give problems. Also 1.2's pdfs 
distills ok. Why does this happen? Can I get a 1.2 that doesnt use this command 
(or can I maybe shut it off manually?)


Thanks,
Kobus

P.S. They use GRAPIX or something like that as rip software.
