| Going
green with printing solutions
These days doing
activities associated with reducing
the risk of global warming similarly
activities concerned with the
are also demanding more attention
towards the efforts concerned with
green activities. It is always essential
to remember that printing
activities can be made
green with the usage of soy inks
that are environmentally responsible
and are quite hygienic as it does
not provide any effects that harm
the environment. The only answer
that has arrived towards the process
of environmentally friendly printing
solutions is the usage of soy inks;
however this is not the only answer
to the entire problem of environmental
pollution.
 The
printers who have
been concentrating towards this
effort of reducing the environmental
pollution have been working on the
process of removing the dangerous
chemicals in their press rooms for
years together. The inks and the
solutions which are used today have
eliminated the usage of the chemicals
like lead, chromium, silver and
they are working hard today to reduce
the harmful volatile organic content.
The process is also under the close
check to monitor and reduce the
waste streams. All these efforts
are very much important for the
fact whether or not they are involved
in the usage of soy inks.
Why has printing with soy
ink become very important
Soy oil based inks
became very much popular several
years ago when they were used as
a replacement for petrochemicals
oils, they are a popular crop grown
by the farmers widely available
in capacity. Soy based inks were
used as a replacement for the petroleum
oils. This issue has gained popularity
as it addresses the various environmental
issues and they have even reduced
the dependence on petrochemical
based inks, they have even reduced
the dependence on the foreign based
products. Other home based products
which are used in the preparation
of inks are cottonseed, vernonia,
sunflower, tung, linseed and canola.
The printing
inks used these days are used in
different classes:
Sheet fed ink which is dried by
the process of oxidation or polymerization Newspaper inks which are dried by
the process of absorption and oxidation.
Heat set inks which are dried by
the different actions of heat.
The American Soybean
association has remained very instrumental
in the late 1980’s in promoting
the usage of soy oils in the printing
inks. They have also established
the minimum percentages of the usage
of the soy oils so as to use the
soy seal which could be used on
the printing base. The minimum levels
of the have been displayed
in the following ways like:
The heat set ink
manufacturers these days are substituted
by the soy oil today instead of
the linseed oil. It is important
to understand that the ink manufacturers
these days are replacing one vegetable
oil for another.
