I don't think circulating 2 different PDF versions of the same KDE promo
file (which even will not display any visible difference on users' screens)
would work. People will not micro-manage 2 versions for themselves. Murphy's
law should tell us that people then will always use the wrong file for
printing  ;-)

My point is: whichever version we distribute should work on all (even older)
PDF viewers and on (also older) Linux printers. And before distributing, let
people run some tests. (It may even be that the current file is working fine
in all viewers and through all printer drivers, and the message in my
cmd.exe console was fake. I've just had bad experience with CS3/4/5-PDFs...)

If you want to retain/restore the InDesign signature in the metadata even
after running it through a sanitizing Ghostscript re-distillation, I can
give you some additional commandline which would do just that. Try this:

    gs \
      -o Kde_booklet_redistilled_by_Ghostscript.pdf \
      -sDEVICE=pdfwrite \
      -c  "[/Creator (Adobe InDesign CS3 \(5.0\)) /Author (KDE Promo Team)
/Title (foobar) /Subject (something) /Keywords (blabla, so-and-so) /DOCINFO
pdfmark" \
 -dPDFSETTINGS=/printer \
      -f Kde_booklet.pdf

This will produce the following metadata as displayed by 'pdfinfo':

Title:          foobar
Subject:        something
Keywords:       blabla, so-and-so
Author:         KDE Promo Team
Creator:        Adobe InDesign CS3 (5.0)
Producer:       GPL Ghostscript 8.71
CreationDate:   09/15/10 16:53:49
ModDate:        09/15/10 16:53:49
Tagged:         no
Pages:          7
Encrypted:      no
Page size:      419.528 x 595.276 pts
File size:      192151 bytes
Optimized:      no
PDF version:    1.4

You could play with the -dPDFSETTINGS= parameter to see some filesize and
quality differences. Supported values to use are "/screen", "/ebook",
"/default", "/printer" and "/prepress". You could even replace the
"Creator:" thingie if you want...

Cheers,
Kurt
