INSIGHT
ENVIRONMENTAL
THINKING
ON A BIGGER SCALE
BY LAUREL BRUNNER
Imagination, ideas and technological innovation are what progress is all about. We care about
what we understand, what we know, so we generally focus only on what directly impacts us. It is
time for this narrow view to change. When it comes to graphics industry inventions that reduce
the impact on the environment, we must start thinking bigger as well as thinking differently.
New technologies for reducing environmental impact cannot be considered in isolation. What
improves a carbon footprint in one way might make it much worse in another.
This is why it is so important to consider all aspects of a machine or system’s
performance when investing. In the printing business it is particularly urgent.
A press for instance may use water based inks that are considered to be less
environmentally hostile than solvent based ones. But if those inks require more
energy to dry, they may not be such an improvement after all.
Water based inks may also have a negative effect on the press itself. A large
packaging provider in Scandinavia has run extensive tests and found that water
can be corrosive to metals in the press. Tests found that excess copper and other
metals were transferred to the cleaning materials, which did not happen with
solvent based inks. The conclusion was that 'water attacks the press in a way
that solvents do not'. This does not mean that we should abandon water based
inks in favour of solvents. But it illustrates the need for more understanding
of what’s going on. We need far more comprehensive evaluations of the
environmental impacts of technological advances.
Balance is very hard to strike if we are to manage environmental impacts
effectively. It can only be established on the basis of verifiable, consistent,
comprehensive and repeatable data, so much more investment is needed into
data collection and analyses. We must not make claims about environmental
friendliness on the basis of a single and isolated data set, as this amounts to the
ultimate in greenwashing. The graphics industry has some tools available to it
for data collection, but not enough. We should be looking more closely at all
parts of graphics production, from prepress through to distribution, so that the
industry can develop datasets to confirm its sustainability claims.
This requires all manufacturers of machinery, software, substrates and
consumables to take a much broader view of sustainability. The big players
have equally big responsibilities. We need lifecycle thinking, starting with raw
materials, manufacturing processes, application, use and end of life. Fresh

approaches to recycling, especially by the sclerotic paper industry would also
help a great deal.
The scale of sustainability concerns facing graphics professionals are huge. But
with a more holistic approach to environmental thinking, the long term future of
the graphics business can be assured.
