Bookblock PDF Requirements – BAM! Publishing

Your bookblock must be PDF/X-1:2001, PDF/X-1a:2001, or PDF/X-3:2002.
Your bookblock must be between 40 and 800 pages.
Your bookblock must be one of the following 5 trim sizes (in inches): 5 x 8, 5.5 x 8.5, 6 x 9, 7 x 10, 8 x 10.
The page size of your bookblock PDF must match the intended trim size for your book exactly. For example, if your book will be 6" x 9", then your PDF must also be exactly 6" x 9".
All pages within your bookblock must be the intended trim size for your book.
All pages must be oriented the same way, and in a way that matches your trim size. For example, if your book will be 6" x 9", then your PDF must be oriented 6" x 9" and cannot be oriented as 9" x 6".
We cannot accept PDFs laid out in double-page spreads.
We cannot take text formatted as 8.5" x 11" and shrink it down to a smaller trim size.
We cannot include bookblocks with bleed. The PDF page size must be exactly the same as the trim size.
Uploading your file to the book machine will not change it in any way (we don't add extra pages, etc.). The one exception is that if you upload a bookblock with an odd number of pages, one blank page will be added at the end of your book.
Crop / registration marks must not be included.
Your bookblock PDF does not include the cover. You will upload or create a cover at a later step in the publication process.
