Company information

Grünig-SignTronic AG – Together. Precise. Progressive.

Grünig-SignTronic AG is globally recognized for absolute precision, Swiss innovation, and uncompromising efficiency in industrial screen-making. Through the official merger of the two pioneering companies Grünig-Interscreen AG and SignTronic AG, the world's leading full-service provider for fully automated solutions in the screen pre-press workflow has been established. What grew over more than a decade as a close technical alliance now provides customers with a seamless, perfectly synchronized product portfolio from a single source.

With production facilities in Schwarzenburg and Rüthi, the company – led by CEO Marcel Grünig – remains deeply committed to a high level of in-house manufacturing and uncompromising "Swiss Made" quality. The modular product range covers every step from frame preparation to the press-ready screen, transforming a traditionally craft-based process into a highly economical, high-tech operation:

• Stretching (G-STRETCH Series): Guarantees an absolutely constant and reproducible screen tension – the very foundation for registration accuracy on the press.
• Coating (G-COAT Series): Offers maximum repeatability in emulsion application to ensure a homogeneous ink deposit.
• Digital Exposure (SignTronic StencilMaster): Completely eliminates the traditional film process. Utilizing state-of-the-art UV-LED technology, it delivers sharp Direct-to-Screen (CtS) exposure without pixel interpolation errors.
• Washing & Reclaiming (G-WASH Series): Ensures eco-friendly, thorough cleaning and precise development of the printed image.

Maximum efficiency is achieved through the MODULAR IN-LINE Systems. These systems physically and digitally link all individual components into a smooth, automated workflow, reducing error rates close to zero. Via intelligent interfaces like the G-Gateway, the installations are fully compatible with modern Industry 4.0 environments.

High-tech solutions from Grünig-SignTronic AG are deployed wherever ultimate quality is required: in technical screen printing (electronics/PCB, photovoltaics), the industrial glass and automotive sectors, as well as packaging and textile printing. With more than 7,000 machines installed worldwide, the company ensures measurable competitive advantages for print shops: superior print quality, drastically reduced setup times, minimized production costs, and reduced waste.
