Printing from Below
For a packaging manufacturer, recycling codes needed to be printed onto carton blanks before the folding process. The challenge: the printhead had to be installed below the production line and print upwards onto moving material.
Most industrial printing systems are designed to print from above. But what happens when the application requires printing from underneath the production line?
The Challenge
The Challenge
The application required:
- Bottom-up printing
- Integration into an existing folding machine
- High print quality
- Production speeds up to 80 m/min
- Flexibility for future applications
Not every marking technology can reliably support such an installation.
The Solution
The Solution
Matthews implemented a solution based on:
- MPERIA® V-Series 32-valve printhead
- MPERIA® controller
- Fast-drying industrial ink
Installed directly beneath the folding line, the system applies recycling codes before the cartons enter the folding process.
Key Features of the Solution
- Built for the environment: Printheads are designed to handle vibration and hold up in demanding industrial conditions
- Flexible setup: The 32-valve printhead is mounted on a movable axis, allowing precise marking along the full length of each pipe
- High-contrast results: The white pigmented ink delivers clear, readable marks on dark metal, even in outdoor environments
- Scalable control: The MPERIA® controller makes it easy to manage multiple printers across one or more production lines
- Simplified maintenance: Integrated flushing systems help extend printhead life and make cleaning more straightforward
The Results
The Result
The customer achieved:
- Reliable bottom-up printing
- High-quality recycling code marking
- Seamless integration into the existing machine
- Production speeds up to 80 m/min
- Flexibility for future applications
