I'm working on a 'coffee table book' with a lot of images and 320 pages. Am I good keeping all as one document due to file size?
It is going to print but also going to be an ebook. So I'm hesitant to say split in to two documents. i.e. Chapters 1-10 and then 11 - 23.
Concerned about file size. I need to send files to printer electronically.
1. Be sure to link, not embed graphics.
2. Since (if you send InDesign files) you have to send a package of file + all graphics to the printer, the overall size will come from the graphics more than the INDD.
3. Serious printers will be used to receiving multi-gigabyte jobs, ask them what they support.
4. Perhaps most printers these days will want instead a PDF made with very specific settings - ask.
If you decided to break the book into individual InDesign documents (as chapters, for example), you can export the whole book as a single PDF or ebook. It's safer to work with a large book in chapters, because if a document goes bad, it isn't the whole book. Use the Book feature (File>New>Book) to synchronize the chapters together and you can do things like change page counts in chapters and have other chapters page numbers adjust automatically. You can also sync styles so that they can be uniform throughout the book.
