The evolution of communications technologies exercises substantial influence on graphic communications products, too. In the world of printing, one group of the iconic products, notably books need to adapt to the challenges posed by digital developments of the 21st century.

The emergence and the extremely swift spread of photo books clearly demonstrate the synthesis and synergy of the two systems.

Novel solutions surface from time to time to enable readers to associate printed information in books

with further information that is available in the digital world. The use of smartphones as a basic device to have access to information seems to be a general trend nowadays, especially among people of younger generations. Such devices are suitable for using certain special symbols, QR codes, passive or active electronic elements that are inserted in the books to become connected to the world of virtual and/or augmented reality.

These solutions raise new demands for binding technologies, as well. Photo books call for special binding solutions that allow or at least approximate full lay-flat binding.
