3. Background Around the year 2000 flexo plate making moved Digital Good cause for it was higher print quality achievable first of all in the Market Segments ‘Flexible Packaging’ and ‘Tag&Label’ Very soon it became apparent that, apart from the quality improvement, there were also work flow advantages by going digital Today, around 75% of all flexo plates used in the printing industry are digital plates 2

4. Background Move from analog to digital in the Corrugated Industry has always lagged behind the above mentioned Market Segments – the share of digital here is only about 50% It’s due to the fact that for a large portion of the Corrugated work there was no apparent quality advantage in going digital – in some cases even adverse effects became visible, such as more fluting visible compared to analog plate printing The challenge is to reduce this fluting effect in order for the Corrugated Industry to be able to catch up with the developments in digital plate making The DuPont answer to it is Cyrel ® DigiCorr™ 3

5. The Cyrel ® DigiCorr™ Solution What is DigiCorr? A modified digital workflow to produce a Digital Cyrel ® plate that is optimized for the needs of the corrugated printer. What does DigiCorr do? The DuPont DigiCorr modified workflow produces a hybrid dot profile for corrugated printing resulting in: Reduced fluting (washboarding) 4

6. 5 How DigiCorr™ works? Cyrel ® DPC or DEC is imaged on a standard CDI as normal. The imaged plate is UV exposed on a DuPont ETL-n Exposure Unit with DigiCorr unit in place The DigiCorr unit is a controlled atmosphere chamber with a corresponding control unit When DigiCorr is in use, the main UV exposure of the digital plate takes place in an controlled atmosphere, free of Oxygen. This produces the unique Hybrid Digital Dot.
