Poly Pretreat can be used for 100% polyester or poly blended substrates.
Direct-to-garment inks are waterbased and, before now, could only to
be printed on a natural, absorbent fiber. If the waterbase
direct-to-garment ink was printed onto a synthetic or blended fiber, the
image would bleed and washout.
With the release of the new Poly Pretreat, direct-to-garment users have
the flexibility to print onto polyester and polyester blends. The fluid
is designed to work with FastInk or Brother’s GT CMYK inks. (Please
note, Poly Pretreat is not designed to work with white ink.)
APPLICATION:
1. Using a hand-held spray bottle or sprayer, apply the appropriate
amount of pretreatment fluid depending on the fabric content for a full
14” x 16” print. (NEVER spray pretreatment on the platen of the
printer.)
- 100% Polyester- 18-20 grams
- 50/50 Blends- 16-18 grams
NOTE: If too little Poly Pretreat is applied, during the wash
test, the image will fade.
If too much Poly Pretreat is applied, the garment will have poor
wash-ability and the garment will stain where the Poly Pretreat was
applied.
2. Heat press the garment for 5 seconds at 356 degrees F (or
approximately 8 seconds for 330 degrees F). Changes in the time and
temperature may be used depending on the results of the wash test.
3. Print using the CYMK inks (Poly Pretreat does not work with white
ink) and cure the garment using the recommended settings for your
direct-to-garment printer.
4. Store Poly Pretreat at room temperature, out of direct sunlight.
IMPORTANT NOTE:
Poly Pretreat acts as a primer by giving inks the ability to be absorbed
by the garment fibers. If you soak the shirt with pretreatment, the
fibers will be so saturated that the ink can not bind at all. This will
cause the ink to wash out or fade very quickly. Several test shirts may
be required before the amount of pretreatment needed is perfected.
