17. Slide 17 drupa 2016
Absorbent substrates
•Good print hold out, cost effectiveness,
excellent printability characterize water-
based inks. Traditional limitations are
being overcome e.g. high speed printing,
chemical resistances.
•Can be used advantageously in
combination with other ink technologies
and print techniques in a wide range of
applications.
Non Absorbent substrates
•Market requirements for technical
performance can be achieved, eg
printing speed, print resistance, bond
strength. Water-based inks gain ground
as a complementing technology in this
application field.
•Technology is characterised by High
colour strength coloured bases.
Consequently low ink film weights can be
applied with associated advantages.
Broad Technical scope

18. Slide 18 drupa 2016
Environmental profile
•VOC emissions are very low.
•Waste water produced can be readily
cleaned limiting the impact of water
consumption.
•Work to develop monomers produced
from bio-reactors is well advanced,
leading to a possibility to decrease
dependence of fossil fuel based
feedstocks in the future.
Workplace safety
•Water-based inks are non flammable and
do not require special workplace
precautions relating to flammability.
•Solvent contents are reduced to a
minimum - need for surveillance of
workers health with respect to solvent
exposure is low.

21. Slide 21 drupa 2016
Summary and conclusion
Water-based inks gain in importance:
•Modern ink formulations and adjusted printing/technical parameters open up a broad
variety of applications.
•Water-based inks are in accordance with EuPIA Exclusion Policy and can fulfill regulatory
requirements for food packaging if neccessary.
•Main applications are flexo and gravure printing with a large product range including
laminated food packaging.
•Water-based inks offer a positive environmental profile.
•Due to their composition handling of waterbased inks is non-critical.
•Total cost profile is competitive.

22. Slide 22 drupa 2016
Summary and conclusion
Water-based inks are already being used widely due to
their strengths today.
In the future they will take their rightful place in each application.
