What Greeny Interscreen does
Grünig-SignTronic AG, operating under the brand Grünig Interscreen, is a privately held Swiss mechanical engineering company founded in 1967 in Schwarzenburg, Switzerland, specializing in screen printing stencil preparation and digital direct imaging equipment. The company manufactures a modular portfolio organized into four product families: stretching machines (G-STRETCH series 201–281), coating machines (G-COAT series 401–421), washing/decoating/developing systems (G-WASH series 034–175XS), and ancillary process equipment including G-DRY drying cabinets, G-PREP high-pressure frame cleaning, G-PROOF inspection/packaging, and G-GATEWAY process automation. Through the SignTronic brand (merged in 2025), it also offers Computer-to-Screen (CtS) direct exposing units (StencilMaster STM series). All mechanical fabrication, controls, software programming, and final assembly are performed in-house at Schwarzenburg, with an engineering/R&D site in Rüthi.
The business operates a capital equipment model: machines are sold worldwide (over 5,000 cumulative units, >90% exported to 50+ countries) through a hybrid channel of regional distribution partners (Marabu in France/Scandinavia/Italy/Netherlands, Simon in Germany, Sefar in Brazil/Mexico, Kiwo Inc and NBC Meshtec in the USA, Kissel & Wolf in Australia) and direct sales (e.g., Canada). Revenue streams include new equipment sales, refurbished/pre-owned machines with six-month warranty, spare parts, and multi-year service/support contracts with customized pricing. Customers span industrial printing (automotive, solar, electronics, glass), textile printing, and graphic sectors, with named enterprise users including Fischer Sports, Glaswerke Haller, Remigius Schneider, CeNTI SCREEN LAB, and Ruy de Lacerda. Industry 4.0 compatibility is delivered via OPC-UA architecture on flagship products such as the G-COAT 414.

Greeny Interscreen competitors and assessment
Company assessmentDirect peers
- ATMA Champ Ent. Corp. Taiwanese manufacturer specializing in precision screen printing equipment, including automatic screen printing machines, exposure units, and associated prepress/preparation equipment. Directly comparable product overlap with Grünig's stretching, coating, washing, and exposing portfolio, particularly for industrial and electronics applications.
- M&R Companies: US-based global manufacturer of screen printing equipment (presses, dryers, conveyor dryers, exposure units, and prepress equipment). Direct peer to Grünig-SignTronic in the screen printing equipment market, with overlapping product categories including prepress and exposure, though M&R is broader in scope across presses.
- INO INO Industrie Officine Meccaniche: Italian manufacturer of industrial screen printing machines and complete production lines. Direct competitor in the industrial screen printing equipment space, with similar focus on automation and turnkey lines for ceramic, glass, and electronics applications.
- Sakurai Graphic Systems Corporation: Japanese manufacturer of screen printing presses and related equipment for graphic, electronics, and industrial applications. Comparable as a specialized screen printing equipment maker with similar end-market exposure to electronics and industrial printing.
Others
- Nazdar Ink Technologies: US-based manufacturer of screen printing inks and specialty printing inks. Adjacent consumables supplier serving the same screen printing customer base as Grünig-SignTronic, with potential overlap in customer relationships though not a direct equipment competitor.
- Marabu GmbH & Co. KG: German manufacturer of screen printing, pad printing, and digital printing inks. Serves as a multi-country distribution partner for Grünig/SignTronic equipment in France, Scandinavia, Italy, and the Netherlands. Adjacent player offering complementary consumables rather than competing equipment.
- KIWO (Kissel + Wolf): German manufacturer of screen printing consumables (emulsions, chemicals, stencil-making supplies) and equipment. Distributes Grünig/SignTronic equipment in the US alongside its chemical product line; an adjacent supplier rather than direct competitor, but its installed-base leverage makes it a relevant ecosystem peer.
- Autotype (MacDermid Enthone Electronics Solutions): Supplier of screen printing consumables, mesh, and stencil-making materials for industrial and electronics printing. Adjacent ecosystem player rather than direct equipment competitor, but its products sit alongside Grünig's equipment in customer screen-prep workflows.
- Sefar Group: Swiss-headquartered global leader in precision woven screen printing fabrics/mesh and screen-making consumables. Functions as both a complementary supplier (mesh is core input to Grünig's stretching machines) and a distribution partner for Grünig/SignTronic in Brazil and Mexico; not a direct equipment competitor but a key adjacent player in the screen-making ecosystem.
Broad incumbents
- Gallus Group (Heidelberg): Swiss-based manufacturer of narrow-web label presses and associated finishing equipment, part of the broader Heidelberg industrial printing ecosystem. Operates in adjacent label and packaging printing rather than screen preparation, but its scale and Heidelberg backing make it a benchmark for what a larger industrial printing player could attempt in adjacent categories.
