Hi Rapha?l,

One thing that strikes me is the 600 dpi for text and images...

A PDF as such is an unRIPped file. So fonts should remain vectors 
thus not carrying any resolution until the RIPping process where it 
will gain it's final output resolution of at least 1200 dpi or 2400 
dpi.

Images are OK at 300 dpi. Some dual resolution RIPs such as the one 
we use will RIP these images at no more than 300 dpi... UNLESS your 
images are line art, which is closer to vector and yes you'd need 600 
dpi (I would recommend 800 dpi for such images) and then we make the 
custom settings on the RIP to accomodate these pages, when it happens.

All this to say that your PDF must be very heavy and for this reason 
won't go through the printing process. This seems to be confirmed 
when you say "small pdf is ok".

I would suggest you discuss the issue with your printer. Why 600 dpi? 
Try with a lower resolution. Images at 100% and 300 dpi will be just 
fine. Some vendors in this industry even claim that at 150 linescreen 
we do not need more than 200 dpi at reproduction size (100%). Don't 
forget that linescreen, even 150 line per inch, "destroy" an image to 
a point where it is hardly usable for any other use than print. Try 
scanning a printed, screened image at a high resolution and see the 
results!

HTH
