How are books bound?
Every bookbinder knows that the spine is where the pages of a book are bound together.

But is this always the case?
A new market development indicates that there is a totally new kind of bookbinding which is becoming more and more attractive: The LayFlat method. This unconventional method is used for coating each underside of a page which was previously printed (folded like a conventional 4-sided page) with adhesive and this is attached by bonding underside to underside.

Why all of this effort?
This is the only way of creating a book item which folds open perfectly flat and shows the print continuously from the left to the right side. No contour trapping, no misaligned printing registrations, no colour differences: one print, one picture, a double page of perfect appearance without a centre fold.
There are multiple applications for this technology. Currently, the introduction and first successes in the sector photo books are under way. In this application, an uninterrupted print and a good flat opening performance are most valued. Experience has shown clearly that the end customer accepts the production cost without questioning if he gets the respective quality in turn. But other applications can also be imagined and have already found market entry. Here an example which could be found in advertising: A car is photographed on a beach for an advertising campaign. The expenses for such an action are enormous. Since a car is represented in landscape format, this would be a perfect scenario for a lay-flat book. The expensive advertisement photo can be displayed across the entire double page without any restrictions. A great achievement for Marketing!
