All text files will be processed and stored in our digital library with a page count that is divisible by two. The last page facing the inside back cover must be blank for insertion of Lightning Source’s barcode containing manufacturing information. If necessary, Lightning Source will automatically add additional pages to achieve appropriate page counts. These additional pages are included in the book’s final page count and the print cost is charged for these additional pages.
Books that are 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 that are larger than 6.14” x 9.21” (234 x 156) will be printed in four-page (two front/two back) single sheet signatures.
