Thermal Transfer Overprinting

DataFlex® 6420

The DataFlex® 6420 is a superior thermal transfer coding solution for flexible packaging applications that demand high performance, ultrafast throughput, and coding flexibility

When uptime and performance are critical and throughput is your goal, the DataFlex® 6420 is the ideal solution. The patented clutchless ribbon drive provides superior uptime by maintaining consistent ribbon tension which virtually eliminates ribbon breaks, while simultaneously ensuring high quality print. The DataFlex® 6420 is available in two print widths, 53mm and 107mm, to meet your specific application needs. The 53mm format is ideal for a range of flexible packaging applications including ultrafast horizontal form fill seal applications with throughput up to 400ppm. When coding applications require a significant amount of content, such as ingredient lists and traceability information, the 107mm format offers the ideal wide format capability.

Uptime Advantage

  • Clutchless ribbon drive maintains consistent ribbon tension, virtually eliminating ribbon breaks and ribbon related downtime
  • Simplest ribbon cassette design on the market, that makes ribbon replenishment fast, ensuring the coder is back on-line and coding with minimum impact to production

Built-in productivity

  • Longer 1200m ribbon length provides more throughput of coded products between ribbon changes
  • A wide ranging selection of ribbons, designed specifically to meet the challenges of flexible packaging applications
  • Patented bi-directional ribbon drive helps ensure that the absolute minimum ribbon is used during each print cycle, providing more prints per roll of ribbon
  • Consistent 0.02” (0.5mm) gap between prints helps ensure highest ribbon efficiency and minimum waste

Code Assurance

  • Advanced coder software virtually eliminates set-up errors
  • Simple message selection reduces the potential for operator errors
  • Range of customer selectable rules and permissions that help to prevent operator error with the printed code

Simple usability

  • Seamless mechanical integration with a range of OEM equipment
  • Comprehensive communications package for host packaging and control
  • Easy to use interface with 8.4” icon based color touch screen
  • Intuitive design features make training and operation quick and easy
