Swiss Precision for More Than 55 Years. [Our history ](/en/company/history)

# Perfection in Screen Making.

For decades, Grünig and SignTronic have redefined the boundaries of screen printing. What began as two specialized companies in Switzerland has become the world's strongest alliance for automated screen making. While Grünig perfected the mechanics of screen handling, SignTronic set new standards in digital screen making with Computer-to-Screen (CtS) technology. Today, we combine these two worlds into one seamless workflow – delivering the 'Perfect Screen' for our customers.
