I don't know the resolution of the PDF that iTunes creates.  Is there any way to find out?
For scribus, I was creating the PDF with 300 dpi resolution.  ghostscript is 8.00 (via fink).

Your questions triggered a thought, and I tried generating the PDF from scribus with 600 dpi.
The results were much better, but not quite as crisp as printing the iTunes PDF.  I showed the
Scribus PDF printout to my husband who said, "It looks like an image."  By pulling a PDF file
into an image box in Scribus, does it turn the contents into an image?  Does it matter if you
have the whole PDF visible or if you effectively crop it (like I am doing) by having the image
box size smaller than the PDF?  Is there any way around this?  Or am I just stuck with this
problem because Scribus is doing what it is supposed to do -- treat the imported PDF as an image?

Now for the oddities I discovered in this process.
I printed out the file directly from Scribus.  Under "Options..." the resolution was 600 dpi.
The iTunes PDF part of the printout was grayscaled and fuzzy, about the same as the PDF
generated by Scribus at 300 dpi.  I also generated a PDF from Scribus with a resolution of 600 dpi.
This took quite a while to generate.  I then printed out that PDF.  This printout differed from printing
directly from Scribus in two ways.  First, the iTunes PDF part was much crisper -- not quite as crisp as
printing the iTunes PDF directly but close.  Shouldn't the two outputs be the same?

Second, the portion of some lines which extend into the
margins in the Scribus file were printed.  I specified not to print stuff that was outside the margins, but
the generated PDF ignored that directive.  Printing directly from Scribus obeyed it.  Is this a known bug
or something I should report?

Thanks for pointing me in the right direction.
