Cugher Glass is excited to present its latest innovation, the Compact 4C & PQVS Series a machine designed to revolutionize the world of printing on square and rectangular glass. Engineered for glass manufacturers requiring reliability and high performance, the Compact 4C stands out for its ability to process glass of varying sizes, from a minimum of 150×50 mm to a maximum of 1300×700 mm, ensuring high and consistent productivity.
Compact 4C Printing Machine: Versatility and High Performance
A key innovation of this series is the ability to handle larger glass sizes compared to the base model while maintaining unaffected printing performance. The print module, equipped with the Cugher E2E (Edge to Edge) system, allows for edge-to-edge printing achievable only through screen printing.
Advanced Features and Printing Precision
Compared to the basic model, the Compact 4C has been equipped with the following features:
The frame washing with extraction without losing registration and the rotation of the printing carriage for squeegee and scraper replacement are just some of the innovations designed to improve operational efficiency and reduce format setup times.
The printing phase is highly precise, with a tolerance between pieces of +/- 0.08 mm. All printing parameters, from pressure to squeegee and scraper speed, are set through the operator panel, making machine setup extremely fast.
Efficiency and Quality in One Machine
The Compact 4C is not only fast and precise but also extremely efficient. It can process up to 550 pieces per hour for glass sizes of 1150×700 mm, making it ideal for high-volume production in shorter times. Additionally, the machine can be integrated with innovative vision systems for quality control, both for glass and print, ensuring high and consistent standards.
A Competitive Advantage
One of the main advantages is the extraordinary flexibility offered at an incredibly affordable cost. This means you can achieve exceptional results while saving at the same time. The Compact 4C transforms your production process efficiently and economically.
Discover the versatility of our machine
The machine is ideal not only for the home appliance sector but also for all industries requiring printing on rigid materials and symmetrical shapes. With this machine, you can undertake any production challenge with ease and precision.
Discover how to take your production to the next level by integrating print quality control (PQVS) into Cugher machines.
With our system, every detail of your print will be monitored with precision, ensuring flawless results and minimizing waste.
The PQVS (Print Quality Vision System) is an automated system for print quality verification on glass, suitable for both screen printing and digital printing. Designed for use in automotive, home appliance, and architectural applications, it can also ensure print quality on other rigid materials, both transparent and opaque, such as polycarbonate or aluminum. Various sensitivity zones can be defined across the glass surface, allowing for higher sensitivity settings in specific areas like logos, barcodes, and other critical elements. All areas of the glass will be inspected and compared with the tolerances specified in the glass inspection recipe.
Key Features:
- Installation: The system can be installed at the center of the precision conveyor belt, provided there is sufficient space for the cameras and illuminator. The system is available in four standard sizes (1000-1300-2000-2600 mm).
- Technical Specifications: The system offers a resolution of 80μm (300 DPI) @2600mm and can accurately verify the quality of the design, detecting circular spots as small as 0.15 mm².
It can identify:
- “Stains” or “spreading” of design details caused by excess ink in screen printing.
- Discolored spots, holes, or missing parts of the design.
Different sensitivity zones can be defined across the entire surface of the glass, allowing higher settings in specific areas such as logos and barcodes.
An additional optional metrological control is available to measure the distance between the print and the edge of rectangular glass.
- Automation and quality control management: The PQVS software can communicate with the printing machine’s PLC, sending predefined signals to activate specific functions. Defective areas and captured images can be displayed on a high-resolution 42″ monitor (optional). The operator can navigate the entire glass surface and, if necessary, zoom in on selected areas to analyze image details.
Once acquired, the image is analyzed using a specially designed and created inspection recipe established during the initial setup. Image processing is handled by a dedicated computer system. The system automatically divides the reference image of the glass into specific areas such as ‘Near the Edge,’ ‘Print Spots,’ ‘Black,’ and ‘Clear Glass.’ For each of these areas, the operator can set different defect tolerance levels, allowing for precise quality control tailored to the various parts of the glass.
With an additional software option, metrology algorithms can be used to measure and verify the external dimensions of the glass. This includes checking the width, height, as well as the positioning and diameters of holes, ensuring that all measurements precisely meet the design specifications.
Don’t settle for less: choose a Cugher machine for superior printing quality and total control over the production process.
