Environmental
Breakthroughs
Clean air. Clean,
adequate water supply. Forest conservation. Safe working conditions.
These
environmental goals are universal, though the degree of concern
may vary from country to country. In some parts of the world, the
printing industry has been specifically cited for its contribution
to the degrading environment.
Waterless printers
worldwide are winning national and international environmental awards
in recognition of their environmental standards, and many have received
ISO 14001 certification for their Environmental Management programs.
VOC-less
Printing Milestone
Many printers
have been drawn to waterless printing because it eliminates dampening-related
volatile organic compounds (VOCs) from the printing process. Some
VOCs have been linked to the deterioration of the earth's protective
ozone layer and, consequently, to global warming. Now,
with the release of water-washable inks, the waterless pressroom
can be virtually VOC-free.
This revolutionary
ink technology, eliminates the need for solvent-based press and
blanket wash solutions, which typically account for a large portion
of a printer's VOC output. The press wash solution is 93 percent
water and 7 percent mild surfactant (soap), with the ultimate goal
of a 100 percent water-washable product.
The environmental
benefits of water-washable inks are far reaching. In some cases
the elimination of pressroom VOCs may even result in expansion opportunities
that were previously limited due to emission restrictions.
Water Conservation
In 1995, 92
percent of the global population had a sufficient supply of water.
If the world continues to consume water at its current rate, it
is projected that water sufficiency in 2050 will be only 58 percent.
It is further predicted that nations will go to war over water supplies
within the next two decades.
Waterless printers
have recorded dramatic conservation of our water resources. A printer
in Switzerland, operating one of the world's first waterless web
presses, eliminated the use of approximately 250,000 litres (about
66,000 gallons) of water in one year. That water would normally
have come from a nearby lake, which is a source of drinking water
for tens of thousands of people.
Forest Conservation
It takes 17
pulpwood market-sized trees to make a ton (907 kg) of paper. Barely
enough to provide a daily newspaper to 20 people for a year. Besides
depleting our supply of virgin fibers for papermaking, deforestation
destroys the natural habitats of countless plants and animals, one
of which may have otherwise provided a cure for cancer.
Because presses
running waterless come up to color and register so much faster,
and hold those consistently throughout the press run, paper savings
of 30 percent to 40 percent have been reported. In addition to saving
trees, that also represents a significant manufacturing and paper
cost savings.
Cleaner Environment,
Better Health
According to
the National Officer for Health and Safety and the Environment,
of the UK's Graphical, Paper and Media Union (GPMU), printers inhale
organic solvents all day long. As reported in the November/December
1998 premier issue of the Environmental Print Journal, the undisputed
effects of occupational exposure to organic solvents include damage
to liver, kidneys and lungs, degreasing of the skin and dermatitis,
mild and reversible effects on the nervous system and more severe
effects from large acute exposure.
The GPMU stipulates
that exposure is highest when printers clean the printing machines
with highly volatile organic solvents, and that exposure increases
where alcohol dampening is used.
Obviously, removing
dampening from the press and eliminating the need for the toxic
substances found in blanket wash solutions will not only ease the
burden on our air, soil and water, it will help protect our most
precious natural resource: Mankind
