Bookblock PDF Requirements

  • 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.
