I am trying to create a pdf for Blurb.com (book printing online). I am using their plugin for Indesign which provides their specs for proper layout. I designed the book, got my client's approval and now that it's time to creat the pdf it holds up. When looking at background tasks I was able to get to 18% done last week but now it's not showing any progress. I've tried their pdf settings as well as PDF/x-3:2002 which they say will also work but I get the same results. I've checked my images and made them as small as possible. I've worked with them on the problem and after a week they said it's not their problem and I should contact Indesign. I am desperate here because my client is waiting for her books and is getting impatient. Thank you.
PDF/X-4 is nearly identical, except that it uses Acrobat 5 compatibility (which leaves transparency live). You can try that and then run the PDF optimizer to flatten the transparency, or make a new preset based on it and change the compatibility. Be sure you set the flattener to High Resolution.

I am checking your suggestion now to see if it's my file or their settings. So far I was able to create the pdf/x-4. Now I'm looking up the transparency flattening. Just found the instructions and I'm going to do that then check the pdf according to Blurb's instructions.
