Presentation of a New Environmental Rating Scale for Evaluating the Sustainability of Digital Printing Systems

摘要

The paper is dealing with an overall rating system for digital printing systems putting different parameters in consideration. Different parameters are used to form a sustainability number of 100, which is a system completely sustainable in use. From 60-100 a system can berated as an environmental friendly ans sustainable system. Different parameters are rated for the number 100 like deinkability, paper quality (FSC, PEFC, paper profiles) energy consumption, CO2 output, VOC figures, toner, inks, used chemicals, percentage of waste paper in production, air pollution, archive quality. All this figures are rated according their importance for the complete environmental process and deinking and paper re more important as energy consumption as an example. Beside this number 100 there are facts like especially toxic and carcinogenic substance or not deinkable which exclude a system to be rated at all. This list will be added as an addendum to this rating system. Different systems will be rated according our new rating system.
