Inkjet Prints Are Not Deinkable
Inkjet
prints cannot be recycled for new newsprint or copying paper just as
old newspapers or magazines. The ink cannot be removed during the
recycling process; it leaves a dark shade for the new paper. The
recycling paper mills can still cope with single inkjet prints from
households or offices. But what printer manufacturers plan to introduce
at the “drupa” fair poses a danger to the paper recycling cycle: Direct
mail or newspapers printed with inkjet act like a sponge full of ink –
and even in small amounts this kind of printed products can cause the
system of graphic paper recycling to collapse.For a couple of
years INGEDE has been trying to solve this problem together with
printer manufacturers and other mem-bers of the paper chain, but
without any success yet. On the contrary – even printer manufacturers
that had focused on excellent recyclable dry toners so far now also
offer inkjet systems for high volumes, blaming market requirements for
this move.“We have to inform publishers and mailing designers”, says
INGEDE’s Press Officer Axel Fischer. “Even a single pub-lisher
investing in this kind of equipment could severely harm paper recycling
all over Europe”. INGEDE plans an in-tensive information campaign in
the forefront of the “drupa” fair, the world’s largest exhibition about
printing and paper early this summer in Düsseldorf in Germany. “We have
to make clear that inkjet printed news and direct mail do not fit into
the higher-grade paper recycling system”, Fischer says. That is why
possibly this kind of printed products have to be clearly visible
marked as “not recyclable”. Fischer adds: “Today, when climate
protection has top political priority, undeinkable print products are a
gross aberration.”At a European Round Table representatives of
the paper industry discuss these issues with members of the digital
printer industry already. For the first time, this year also inkjet
manufacturers want to join the talks. INGEDE hopes that this helps at
least in the long run to direct further development towards better
deinkable systems. “Already when designing a print product, a publisher
or as marketing agent has to take recycling into concern”, Fischer says.Dry
toners perform very well in the paper recycling process that originally
has been developed for the removal of offset and gravure inks. A series
of tests by different European research institutes on behalf of INGEDE
has confirmed these findings.INGEDE is an association of leading
European paper manu-facturers founded in 1989. INGEDE aims at promoting
utilisa-tion of recovered graphic paper (newsprint, magazines and
office paper) and improving the conditions for an extended use of
recovered paper for the production of graphic and hygiene papers.
