Endpaper or endsheet — To Print or leave plain.
An endpaper or endsheet is seen in the photo. “Ends” glue to the inside front and inside back cover of a hard case book. They may print or not. If they do not print with a solid color, a Pantone ink, a design or photo, they will be white, or the color of the paper. Uncoated paper stock is standard, but ends can also be made coated stock.
An Endpaper or endsheet for Print on-Demand books versus Printing on Press books
Unlike print on-demand books, books printing on press have the endpaper or endsheet that are twice the width of the text page dimensions.
One or both sides may print. When calling out the dimensions of a book, we use just the size of the text page. If the text pages are 6 x 9, a hardcover book will be slightly larger because the boards are larger than the text pages.
But, what about the ends, because POD hardcover books do not bind in the same way as with traditional book printing and binding. The endsheet of a 6 x 9 book that prints on-demand, will be 6 x 9. The endsheet of a book that prints on press will be twice the width. The size is 12 x 9.
The 8 page endsheets file is comprised of:
Page 1. Glues to inside of front board (always blank)
Page 2. Inside of front board (page 1 of front spread)
Page 3. Facing front board (page 2 of front spread)
Page 4. Facing first page of text block (blank if printing ends 4C/0C or 1C/0C)
Text block lies between the front and rear endsheets
Page 5. Facing last page of text block (blank if printing endpapers 4C/0C or 1C/0C)
Page 6. Facing back board (page 1 of rear spread)
Page 7. Inside of back board (page 2 of rear spread)
Page 8. Glues to inside of rear board (always blank)
Presenting the final PDF in this manner eliminates any source of confusion for the printer regarding pagination of your ends.
Page 1 is always a right-hand page as viewed in InDesign. See more in the Endpapers Guide.
