Blank End Pages

If necessary, Lightning Source will automatically add blank pages when processing the files or when printing and binding the book.

Reasons why blank pages are added to the book’s interior/text file:

All interior/text files for print books are processed and stored in our digital library and the page count must be divisible by two. Pages that are added during the processing of the files are included in the book’s final page count and the additional pages will incur print fees.   

The last page of the book, facing the inside back cover, must be completely blank for the barcode that is added. This barcode allows the interior book block to be matched up with the proper book cover during the manufacturing process. 

If your interior file does not have a blank page at the end, we will automatically adjust the file. A blank page is defined as totally absent of any content; this includes headers, footers, page numbers, and blank fields. Blank fields, which you can’t see, can be caused by pressing the space bar or not deleting all the blank spaces on the page.

Reasons why blank pages are added during the manufacturing process:

There are times during the manufacturing processes of printing and binding when a book may need to have additional pages added, which you are not charged for. (Example: the stored file is 26 pages (not divisible by 4 or 6) and 2 pages are added when printing as four-page or 4 pages are added when printing as six-page).

Books files created with a trim size of 6.14” x 9.21” (234 x 156) and smaller will be printed in either six-page (three front/three back) or four-page (two front/two back) single sheet signatures.

Books files created with a trim size larger than 6.14” x 9.21” (234 x 156) will be printed in four-page (two front/two back) single sheet signatures.

Premium Color book interior files are processed with page counts divisible by 2 and printed with page counts divisible by 4.

If you want to ensure no blank pages are added during the manufacturing process, the book’s page count should be divisible by 12.
