Maker KBA says new inks for its 762 mm-wide RotaJet L-Series inkjet web have been INGEDE certified.

The International Association of the Deinking Industry checked test prints from the newly developed inks used to print on coated stock at DRUPA were shown to be "extremely deinkable".

The process of removing ink or toner from paper is an important part of the recycling process, and certification follows tests in 2014 when RotaColor inks from the earlier RotaJet 76 were certified as extremely deinkable.

"The very good results achieved once again by the high-volume inkjet press from KBA clearly show that it is possible to design inkjet print work in such a way that they can be easily integrated into existing recycling chains," says INGEDE recycling print products expert Axel Fischer.

Samples were evaluated according to the European Recovered Paper Council's Deinkability Scorecard (ERPC 2015), soring 100 out of 100 points. Polymer technology prevents the pigments from penetrating the fibres, with pigmentation ensuring cellulose fibres retain their natural characteristics.
