1. Cyrel ® DigiCorr Higher Quality Graphics for Corrugated Board

2. 2 Around the year 2000 flexo plate making moved Digital Driver for this was higher print quality achievable first of all in the Market Segments ‘Flexible Packaging’ and ‘Tag&Label’ Very quickly 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 Background

3. 3 Move from analog to digital in the Corrugated Industry has always lagged behind the other Market Segments mentioned – here the share of digital is only around 50% This has been 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, which was more apparent fluting as compared to analog plate printing Now 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 DigiCorr The DuPont Cyrel ® answer to this challenge is DigiCorr Background

4. 4 A workflow innovation to produce a Digital Cyrel® plate that is optimized for the needs of the corrugated printer. What is DigiCorr? What Does DigiCorr Do? The DuPont DigiCorr modified workflow produces a hybrid dot profile for corrugated printing resulting in: Reduced fluting (washboarding) Improved solid ink density Superior highlights & vignettes Improved run length The DigiCorr Solution

5. 5 Cyrel® DPC or DEC is imaged on a standard CDI in the normal manner How DigiCorr Works The imaged plate is UV exposed on a DuPont ETL Exposure Unit with DigiCorr unit in place The DigiCorr unit is a controlled atmosphere chamber with its corresponding control unit When DigiCorr is in use, the main UV exposure of the digital plate takes place in an “inert atmosphere” free of O 2. This produces the unique Hybrid Digital Dot.

14. 14 DigiCorr Benefits Simple to use process Switchable, only use when altered dot profile preferred No additional plate material needed Superior corrugated print quality DuPont DigiCorr will provide the Corrugated Tradeshops and Converters with a competitive quality advantage

15. 15 DigiCorr Benefits Some printers still think that very thick printing plates are necessary in order to successfully print on corrugated board in order to allow for it to adapt to the wavy surface With DigiCorr this for sure is not necessary anymore Combine DigiCorr and Thin Cyrel® Plates and you will enjoy Better Print Quality Ease of Handling Environmental Sustainability When doing your next investment into new printing presses, consider to not go thicker than 155 mil / 3.94 mm for your printing plates!
