6 The Digital Advantage Ensuring Digital = Sustainable Growth 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)
