[scribus] Saving as PDF with a smaller file size

[Christopher A. Zaino, PT, PhD]

I am using Scribus 1.4.0.r5 on linux mint 10. I have a two page 
newsletter with 2 small pictures, some graphic shapes, some PDF 
hyperlinks, 5 layers. When I export this newsletter to a PDF format, it 
is quite large (19 mb). This is a problem because I need to email this 
newsletter to a group of people. So I need a smaller file size.

I have tried saving in various ways - PDF 1.3, 1.4, 1.5, I have changed 
the resolution of the pictures to 100, 125, 150 dpi (originally it was 
300 dpi) and it always saves at the same 19 mb. However, twice I have 
tried something and it will save at 1.3 mb or 1.8 mb, but when I try it 
again using the same (?) settings, it is back to 19 mb.

Does anybody have any suggestions on how to save the file to PDF with a 
smaller size - any settings I should be aware of or should I decrease 
the number of layers. I like the layers because I can move about the 
document easier with the layers - I have text on one layer, graphics on 
another, pictures on another.....

Also, any clue as to why I would get one size file most of the time and 
then have a drastically smaller file, but can't duplicate it within 
seconds of saving the first (smaller file)?

thanks

Chris
