Test prints with newly developed inks that were used to print on coated stock at this year’s drupa and were evaluated by INGEDE were shown to be extremely deinkable. Deinking, the process of removing ink or toner from paper, is of great importance when it comes to an orderly recycling chain.
“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,” said Axel Fischer, expert for recycling print products at INGEDE. RotaColor inks from the previous press series the RotaJET 76 were certified as extremely deinkable in 2014.
The print samples were inspected in accordance with INGEDE Method 11 and evaluated according to the European Recovered Paper Council’s Deinkability Scorecard (ERPC 2015). The RotaJET L-Series received 100 out of 100 points.
The KBA RotaColor polymer pigment inks have been constantly improved to build on the very good result achieved in 2014 even further. The KBA RotaColor inkjet inks benefit from polymer technology that prevents the pigments from penetrating the fibers. The pigmentation of the inks has been perfected to ensure that the paper’s cellulose fibers retain their natural characteristics and are not compromised.
