  1. Advancements in Flexo Technology Paul MacdonaldSales Manager Mark Andy UK

  2. 1973 pressure sensitive press. Look how far we have come....

  3. Issues with older Flexo Technology • Many improvements over the years • However – issues remain • Longer changeover times • Extensive setup material waste • Poor and inconsistent print quality • Higher running material waste • Inconsistent output between operators • Long training curves for new operators

  4. Converter Challenges • Increasing substrate costs • Increasing ink costs • Increasing plate costs • Commoditized business • Price pressures • Shorter run lengths • Difficulty finding/keeping skilled operators Converter

  5. What has changed with flexo press technology? • Over the past few years, new flexo presses have hit the market: • Elimination of multiple adjustments • Discrete, repeatable settings • Automatic positioning of all print head components • Elimination of time consuming adjustments for repeat changes • Servo driven • Ultra-short web paths

  6. Outcomes of new flexo technology • Improved and more consistent print quality • Faster changeover times • Reduction in waste • Enhanced capability • More consistent production output – from lower skilled operators • Two for one replacement of old flexo technology • Pushing back on digital breakeven for shorter runs First colorimpression First good label

  7. Digital/Flexo breakeven New flexo Traditional flexo Typical digital solution Job cost Job size

  8. What are the challenges going forward? • Eliminate remaining bottlenecks • Energy conservation/environmental focus • Reduction in waste • Enhanced capability • Down-gauged liners • Continued price pressure • Increasing costs • Shrinking labor pool New technologies are on the way to help...

  9. Diecutting • Single biggest remaining bottleneck in converting today • New solutions offer several benefits • Single minute changeovers • Improved ergonomics • More consistent die cut quality • High speed stripping • Difficult die shapes • Results • 60% setup reduction • Increase in press speeds by 150 fpm or greater • Elimination of potential injuries

  10. LED UV • The future in UV curing • Many benefits • Instant on/off • No ozone generation • Low heat – No IR energy • High energy efficiency • Longer lamp life 22,000 hrs plus • Dependability • Durability – fewer moving parts • Full ink sets now coming to market • Technology on display at UK Show Room and Labelexpo 2013

  11. Advanced Drying Systems • Press speed is often limited by drying capability • Growth into short run flexible packaging has brought more attention • New technology allows high speed drying with several advantages • Low energy consumption – significant reduction compared to compressed air • Small footprint – ability to dry heavy coverage in 1/3 of typical web distance • Low heat output – good compatibility with filmic and other heat sensitive materials

  12. Future focus • Predictive performance • In-line measurement and control • Full system integration • Enhanced capability • Continued process simplicity

  13. Automation • Automation currently exists on current newer press models • Typical automation approach has been focused on traditional manual operations • Incremental improvements through servo implementations • No unique value unlocked The future: • Total system approach to automation • Unlock values previously unavailable to converters • Full integration of tooling and system

  14. Unlocking value – an example • Dies are made with important information in mind Blade depth Die repeat Liner thickness Blade angle • Imagine if – the press could “communicate” with the die • How could this information be used? • Set anvil depth for liner thickness • Track die revolutions/die life • Automatic compensation for die wear • Set appropriate die cutting pressure • This is just one example of future developments....

  15. The future of flexo is bright • Significant strides have been made in over the past couple of years • New flexo presses have significantly increased productivity • Near term developments will help break down existing bottlenecks • Future developments will unlock unique value for the converters
