The new series has it all: it is just as durable and you can open it flat to your viewing pleasure. Flatbooks are available with all types of finish offered by Krubook.

Thanks to additional creasing at the spine, Flatbooks show reduced paper tension and open with ease. This makes it possible to open the book almost completely flat! Now you can create albums with an entire image over the entire spread without losing parts of the image at the spine (you just need to adjust the design for varying bleed at the spine). Flatbooks are available in all types of finish offered by Krukbook.



  • FlatBook is our enhanced standard book – creasing makes it possible to open it flat
  • recommended solution for thin or narrow book designs.
  • when open, the book does not ‚close by itself’ because of paper tension.
  • full bleed designs possible (only after manual adjustment of the appropriate bleed value at the spine!)
  • up to 120 pages
  • all types of finish offered by Krubook.
  • enhanced mechanical durability (glue free binding!)
  • attention: we advise against using black background at the creasing

How to order?

Just click the „flatbook” option when you order through the client panel.

How do I design a Flatbook?

The easiest way is to use our software, but you can use third party software as well.

The important thing to know is that books are sewn parallel to the spine and that is why part of a page near the spine will be used up by the area of the page that is sewn. In other words we need a bleed area near the spine of the book. For seamless spread designs – so that an entire image is visible on both pages when the book is opened flat – this bleed value needs to be taken into account when you design your book. The tricky part is that the bleed value changes with the number of pages (due to the thickness of paper). The greater the number of pages – the greater the bleed value near the spine:

for 150g paper: 1mm with every 6 sheets of paper (12 pages)

for 170 g paper: 1mm with every 7 sheets of paper (14 pages)

The way to design a seamless spread (so that no image area is lost at the spine area) you need to duplicate and adjust the image so that bleed areas at the spine on both facing pages contain the same (duplicated) part if the image you want to show on a spread.

If you are having problems with this type of design just e-mail us for detailed guidelines.



Images show 40 to 60 page books. Every Flatbook opens easier and shows reduced paper tension thanks to additional creasing and unique sewing process. However, this unique manufacturing process requires a special design process which takes into account the varying bleed at the spine.
