19-20 September 2018
IMI Europe Digital Printing Conference
In his presentation at the IMI Conference, Axel Fischer of INGEDE asked Is Inkjet Still a Challenge for Paper Recycling and Deinking?
Printers want to go green. Some think, water is green, just because it is water? It isn’t always.
Water soluble inks in printing are not necessarily environmentally friendly. Cheap dye-based inks dissolve during the recycling process, staining the fibre rather than leaving the mix in a process designed to remove 1) hydrophobic 2) ink particles.
Deinking has soap bubbles rise to the surface, pulling hydrophobic ink particles up and away. Here dyes and inks with hydrophilic small particles make a print behave like a red sock in a washing machine – staining all the fibres in the system, not just the one they are intended to colour.
Better systems are available: The presentation gave an idea how to do it. You can download the pdf here.
