Print ready files: PDFs won't convert (keep having an error)
So, I am using Indesign CC to make a print book. I'm using Lulu's full bleed PDF job options. I've used these job options before on the same indesign files I'm using now, but have started having problems.
The problem I am having is, I recently updated my Indesign document (corrected some typos) and exported it the same way as usual, but when I get to the stage where I have to convert the PDF to a print ready file... it takes several hours, and then gives me an unexpected internal error message.
I've tried re-exporting the PDF from indesign a few times and doing this again, I've tried making a new project from scratch. Same problem.
I've found I can get the PDFs if I export them as separate chapters to convert into individual print ready files, but the conversion process breaks when I try to export them all together.
I also tried making a print ready file by adding all the separate chapters to the book and then running the converter, but while it can handle them individually, it fails if I try to add them all to the project together. This would not be ideal in any case because I need the document to have bleed, and combining individual chapters results in losing that.
The files are well under the maximum, at just slightly over 80mb, so I know that's not the issue.
I really really need to get this book ready this week and make an order, I've sent an email to Lulu, but haven't heard from them yet. I know they try to get back to people ASAP and I would give them that I've actually been impressed by their customer service thus far.. but this is a situation where I'm really in a hurry to update the project with typos fixed and get it shipped off. I've been trying for 2 days to get the file to convert to print ready.
What should I do?
