For Müller Martini, the buzzword Finishing 4.0 meant digital connectivity and the ability to change between formats - and even individual products - almost instantaneously.

Nine different solutions were to be seen around the show producing 20 different jobs with a claimed 100 different end products.

Chief executive Bruno Müller (left) says half of all the systems now sold have some provision for digital production. 'Touchless' workflow has the machines preparing themselves automatically for each new product based on job data and stopping only for rare manual interventions. Demonstrations also showed how digitally-produced and offset elements could be integrated.

At DRUPA, nine connected production lines in saddlestitching, perfect binding, hardcover production and newspaper inserting segments were producing a wide range of different products, which might include single-copy products with different sizes, pagination and formats. An educational book with a range of titles and content was one example, produced from the web on a line comprising SigmaLine, Vareo and InfiniTrim elements, as well as partner components.

Personalised book blocks were also produced in sequence in runs of one copy with the company's SigmaLine book system under Connex VDP control, with eight titles perfect bound by the servo-driven Vareo.
