I reported here quite some time ago problems where illustrator patterns
would simply vanish with many PDF RIPs, although they would show OK on
screen. This problem is very specific to versions pre-7 of illustrator
(where patterns were internally coded as type 3 fonts, if I remember
well). Then, saving as AI-EPS 6 may be the wrongest choice! I have
encountered no difficulty with patterns in illustrator since version 8
(saved as version 8 !). The next problem being with transparency &

That's _my_ way of preflighting. It _is_ useful: you can predict most

correct settings) and looking to things that were converted to bitmap
[transparencies...], disappeared [fonts or patterns troubles...], colors
that changed...
