Ensuring Digital = Sustainable Growth
•The Digital Advantage
•Reduced inventory, spoilage, over-runs – helps reduce carbon footprint
•Targeted, customizable applications ensure high value prints – better use of resources •Opportunities for greatly reduced VOC emissions
•Highly scalable solutions, well-suited to distributed print models – reduced transportation footprint
•Digital Print Recyclability/Deinkability
•Digital prints currently very small percentage of total paper stream
•But ensuring a smooth transition for paper recycling / deinking industry toward a ‘more digital print’ future is essential
•The Digital Print Deinking Alliance (DPDA) formed in 2008 to address that responsibility for inkjet press mfgers
•Current members include HP, Infoprint Solutions Company, Kodak, and Océ Printing Systems
•HP-sponsored independent lab results showing encouraging deinkability results for HP Indigo Electroink (LEP) and HP Inkjet Web Press pigment inks (see next slides)

Ensuring Digital = Sustainable Growth
The digital opportunity for the overall print industry is compelling
•Digital = Business Growth…for print providers, printer mfg’ers, paper mfg’ers•Analog to Digital print transformation technologies such as LEP and Inkjet provide opportunity for environmental impact reduction
•DEP is an important A to D component but does not fully address the market needs
•Data show that HP LEP & Inkjet inks are well-suited to deinking processes in general •Collaboration is essential to find the optimum overall solution
Printer Design/ Mfg Deinking/ Recycling Paper Making
• Ink, Paper, Deinking – finding pragmatic, cost-effective compatible solutions • Brilliant output on
recycled grades • Digital printing for
sustainable growth
Chemical Additives
• Pulp supply should enable high recycled content in various grades
