Screen printing represents MCS’s first true production process – a milestone that marked the company’s transformation from a pure PCB Master design firm into a specialized manufacturing centre.
It was 1989 when, thanks to the collaboration with a “master of silk screen printer” – as we still respectfully call him today – who had gained experience in the demanding German market, the company embarked on this path.
The initial choice to invest in second-hand equipment reflected the entrepreneurial prudence of the time, but also confidence in a process that, despite its apparent simplicity, requires skill, experience, and vision (more than cutting-edge technology).
The Screen-Printing Process: Technical Precision and Quality Control
Screen printing is a technology that, in essence, transfers ink through a fine mesh screen onto a substrate. However, this simple definition hardly captures the technical complexity and the high level of control required in an industrial environment.
In-House Screen Preparation: A Guarantee of Quality
At MCS, all screen frames are prepared internally through a photographic imaging process.
This approach ensures:
- Total control over stencil quality;
- Micrometric precision in defining ink passage areas;
- Absolute repeatability for series production;
- Rapid response times for design changes or new implementations.
The open areas of the mesh – the “uncoated screen” – determine the selective passage of ink, allowing the desired graphic to be transferred onto the substrate.
Ink Versatility: Tailored Solutions for Every Industrial Need
Our screen-printing department uses a wide range of ink formulations, each optimized for specific applications:
- Solvent-based inks: for applications requiring maximum adhesion and chemical resistance;
- UV-curable inks: instant polymerization for faster, more flexible production, ideal for film materials;
- Conductive inks: essential for creating circuits in membrane keyboards.
Production Capabilities: From Flat Sheets to 3D Components
The versatility of our screen-printing department is reflected in its ability to process a wide variety of materials and geometries.
Film materials (sheet form):
- Polyester and polycarbonate: for overlays, labels, and flexible circuits;
- PVC and adhesive materials: for simple label applications.
Rigid sheets:
- Anodized aluminium and coated metals: for front panels, rack panels, and electronic enclosures;
- PMMA (plexiglass) and polycarbonate: for transparent applications;
- Rigid PVC, HIPS, ABS, etc., in various standard colours;
- Stainless steel: for metalwork panels and enclosures.
Printing on three-dimensional objects:
One of our department’s distinctive skills is the ability to print directly onto formed metal housings and enclosures for electronics.
This eliminates the need for adhesive labels after production, ensuring a permanent, professional marking directly integrated into the product.
The Team: Experience and Specialization Serving Quality
Three specialized technicians work in the department, each with many years of experience. This stability guarantees:
- Consistent quality across production runs;
- Consolidated know-how for solving technical challenges;
- Process optimization through accumulated experience;
- Continuous training on new technologies and materials.
Screen printing requires not only technical knowledge but also manual skill, precision, and attention to detail – qualities that can only be developed through years of direct experience and genuine passion.
Sector Specialization: A Strategic Choice
While many competitors have diversified into advertising graphics, promotional printing, or textiles, MCS has made a deliberate strategic choice: to remain exclusively focused on the electronics and instrumentation industry.
This specialization brings concrete advantages for our customers:
- Technical expertise specific to electronic applications;
- In-depth knowledge of industrial standards and regulations;
- Careful selection of materials and inks compliant with electronic requirements;
- The ability to communicate effectively with engineers and designers, speaking the same technical language.
Screen Printing and Digital Printing: A Strategic Complementarity
A common question concerns the relationship between screen printing and digital printing.
At MCS, we operate both technologies – and our answer is clear: they are complementary, not competing processes.
Unique Advantages of Screen Printing
Superior colour performance
- Metallic colours;
- Fluorescent tones;
- Fully opaque inks;
- High chromatic accuracy with RAL and Pantone references;
- Perfectly uniform solid colours (unlike digital printing, where colours are created from dense CMYK dots, always slightly visible).
Exclusive technical functionalities
- Conductive inks for flexible printed circuits;
- Full control over ink chemistry for compatibility with diverse materials and substrates;
- Resistance to solvents and aggressive chemicals;
- UV stability for outdoor applications.
When Screen Printing Is the Optimal Choice
Screen printing proves technically and economically advantageous for:
- Series production with identical graphics and limited colour ranges;
- Flat colour graphics without photographic gradients;
- Applications requiring extreme durability;
- Metallic or fluorescent effects not reproducible digitally;
- Difficult substrates requiring specific inks.
Practical Applications in the MCS Portfolio
Industrial membrane keyboards
Screen printing is the core technology behind our membrane keyboard production. It enables:
- Reverse-side (second surface) printing on polyester and polycarbonate for maximum protection;
- Precise, repeatable deposition of silver conductive tracks;
- Permanent readability even after millions of actuations;
- Transparent coatings for display areas.
Front panels and customized enclosures
For electronic housings, screen printing allows professional customizations such as:
- Corporate logos with exact Pantone/RAL matching;
- Aesthetic and functional personalization;
- Technical symbols;
- Graduated scales;
- Connection schematics.
Added Value for Our Customers
Choosing MCS for screen printing means benefiting from:
Integrated process control
- Complete in-house production chain: from design to manufacturing;
- Reliable lead times: no dependence on external suppliers;
- On-the-fly modifications: immediate flexibility and responsiveness.
Certified and consistent quality
- Colour consistency guaranteed batch after batch;
- Spectrophotometric colour control;
- Dimensional checks with calibrated instruments;
- Adhesion and resistance testing in compliance with industry standards.
Economic optimization
- Economies of scale in series production;
- Fast amortization of setup costs;
- Waste reduction through consolidated experience;
- Technical consultancy to identify the most efficient solution.
Continuous Innovation, Rooted in Tradition
Our screen-printing department perfectly blends craftsmanship tradition and technological innovation.
While the fundamental principles remain those established decades ago by our “master of screen printer,” continuous evolution is reflected in:
- Selection of high-performance inks;
- Advanced control systems ensuring repeatability;
- Integration with other in-house manufacturing technologies;
- Ongoing staff training on industry best practices.
Conclusions: A Strategic Department for Integrated Solutions
At MCS, screen printing is not merely an accessory service – it is a strategic asset that enables us to deliver complete, integrated solutions for the industrial electronics sector.
The combination of over thirty years of experience, sector specialization, and integration with our other technologies (CNC milling, 3D printing, digital printing) allows us to position ourselves not just as a supplier, but as a technical partner capable of transforming design specifications into finished products of excellence.
