# Customer References from Real Production Environments

With the solution from Grünig-SignTronic, we have definitely killed this.” Jehan Garnier Industrialization and Order Handling Mgr SERTIP group · France](https://www.groupesertip.fr)

[“Since 2015, we have been using the G-PREP 370 system for automatic frame cleaning. It accelerated the prepress preparation process so significantly that we invested in another system in 2021\. In addition, we use G-BOND on the 275 system, three coating machines (406, 415, and 421), as well as the 280 stretching system.” Salvatore Giuffrida Operations Management Remigius Schneider GmbH · Germany](https://www.remigius-schneider.de)
