Two strong brands, one shared path
Grünig-Interscreen AG and SignTronic AG merged retroactively as of 1 January 2025 to form Grünig-SignTronic AG. Contacts, support and both sites remain.


Grünig-Interscreen AG and SignTronic AG become Grünig-SignTronic AG.
After more than ten years of successful partnership, Grünig-Interscreen AG and SignTronic AG are taking the next logical step:
Retroactively as of January 1, 2025, we have merged – and from now on, we operate together under the new name Grünig-SignTronic AG.
💡 Why this step?
Because we firmly believe that the whole is greater than the sum of its parts.
By combining our strengths – screen preparation and digital direct imaging – we’re creating clearer processes, seamless interfaces, and fully integrated solutions from a single source.
For our customers & partners, everything you value remains unchanged:
✔️ Your trusted points of contact
✔️ Ongoing support for all existing systems
✔️ Both locations – Schwarzenburg & Rüthi – will remain
✔️ Quality, service, and availability at the same high level
🗓️ The organizational and visual transition will be rolled out gradually by the end of 2025.
🤝 This merger is more than just a new name.
It is a clear commitment to long-term stability, technical excellence – and to our customers around the globe.
Grünig-SignTronic AG – thinking ahead. Together. For more efficiency, precision, and partnership.
