Wary of
White DTG Ink?
Understanding chemistry and clogging
can make printing with this ink type easier.
By John LeDreW, ConTrIBuTInG WrITer

With direct-to-garment (DTG) printing,
white ink always is a focal point. Its detractors routinely point out the following: it
doesn't work well, is expensive, clogs systems and is not sustainable for production.
These valid concerns historically have
been the bane of DTG owners' existence
far and wide.Technology has evolved, however, and nearly every DTG equipment
manufacturer has taken steps to mitigate the
issues associated with white-ink delivery.
Using white ink effectively requires
examining the characteristics that make
it problematic, what is required to make
it work properly in a DTG system and
what manufacturers are doing to address
these difficulties.
Encapsulation Chemistry
"All white ink is the same; it's all DuPont."
I routinely hear this statement at industry
trade shows, but it's only half true.All ink
requires pigment (dye molecules) to define
color, and a high percentage of printer-ink
pigment is made by DuPont. This is the
sole characteristic that most printer inks
have in common.
White-ink pigment is composed of
titanium dioxide (TiO2), which often
is referred to as "the perfect white" due
to it's high refractive index. It is used in
toothpaste, paint, sunscreen, pills, plastics,
finishes and more.
The major difference among the
available white inks is the chemistry of
the encapsulation of the DuPont pigment in the carrier or solution, which is

proprietary by each manufacturer. Simply
put, some DTG ink encapsulation chemistry is better than others. Let's examine
some key components of chemistry that
increases white-ink reliability in a textile
application.
There are two types of printer ink: sol-

vent and aqueous.Textile ink is aqueous
(water-based) and must be used in a system
that is designed to sustain water's degrading
properties.A good example would be adhesive labels on a container. Some - when
submerged in water - continue to stick,
while some peel away.
