Traditional screen printing is a very old but proven process
for printing t-shirts. the quality is great but you still need to burn
multiple 'screens' and squeegee ink through each one to get a multi-color
design. Thus, there is A LOT of physical
set-up for a screenprint run. This is
why screenprinters impose minimum order sizes….so they can spread the cost of
their time to set the machine up over a lot of t-shirts.
DTG or direct-to-garment printing came out a few years ago
as a way to avoid this set-up. They are
essentially inkjet printers but the paper is a t-shirt. The big problem is printing white ink. For a whole host of technical reasons that I don’t
even fully understand, white ink must have plastic in it in order to adhere to
a t-shirt. Since inkjet printers use
printheads with tiny nozzles, pushing ink with plastic in it through a print
head is difficult and creates a residue which ‘gums up’ the print head making
it inoperable.
Anyway, a company named Kornit came out with a really expensive
alternative a few years back which the VC funded companies like cafepress,
zazzle, etc bought to produce single unique t-shirts. Now Brother has come out with a less
expensive alternative. We are excited to
see it in action and hope to offer dark colored t-shirts and sweatshirts
soon. Below is a video someone took at
the recent SGIA show:
