How did you produce this? Scan three images, convert those to PDF, 
put PDFs into imageframes in Scribus, produce PDF?

Dont Do That!

Bitmap images are extremely sensitive when being scaled to near 100% but not
exactly 100%.
That's why you scan at least at 400 dpi if your output is 300 dpi. 

In your case the image on the first page is probably scaled twice: once when
the PDF is placed 
(likely at 99,5% or 101% or someting similar) and the second time when the
page is output.
To avoid this, use the images (tiffs?) you get directly from the scan
process and place those
in Scribus. If you need to scale, avoid percentages near 50%, 100% or 200%.

Scanning at a higher resolution might also help.
