We here at Selfpublishbooks.ie just got a lovely book report back from the Henkel Lab Graphic Arts service. They tested one of our Otabind books for bind quality, and this – in a nutshell – is what they found:
The strength of the bind of the pages is almost three times the UK minimum standard. Furthermore, this outstanding result is achieved using only .2 mm (point 2 of a millimetre) of PVA on the page edge. This minimum amount of glue, combined with the unique Otabind feature (the gauze on the book block), and deep notching, gives us not only this superior strength, but also the “lie flat” finish to the book which is so attractive.
