  • Logo Remigius Schneider GmbH

    With the G-Prep 370, we successfully standardized our frame preparation process. The cleaning results for bonding are absolutely consistent, the operation is intuitive, and the system runs very reliably.

  • Logo SERTIP group

    Before installation, we were managing crazy storage of films - more than 40,000 - with all costs and quality issues related. With the solution from Grünig-SignTronic, we have definitely killed this.

  • Logo Siebdruckbedarf W. Schmitz GmbH

    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. With Grünig screen printing machines, we see the best opportunity to combine automated and standardized work in the future.

    With the SignTronic system, we were able to noticeably improve our print quality while simultaneously reducing time and costs in our print shop. We were particularly impressed by the competent consulting, the smooth delivery and installation, and the thorough training of our team.

  • Logo THERMOTEX DRUCKVISIONEN GmbH

    Due to capacity demands in single-shift operation, we had to completely restructure our screen-making department. Today, with our three fully automated lines for screen coating, screen exposure, and screen cleaning, we are ideally positioned to continue growing while maintaining single-shift production. We value the quality and the long-standing partnership with Grünig-SignTronic.

  • Logo BEG BARBOSA ESTEVES & GONCALVES LDA

    At BEG-Printhouse, we are extremely satisfied with our investment in the CtS system from Grünig-SignTronic, which we have been using since 2024. Compared to our previous laser-ink solution, this system represents a significant improvement. We were able to significantly increase the quality of our screens as well as the production speed.
