Must be able to handle the area of Platen 14 x 16 (355.6 mm x 406.4 mm) and maintain heat production of
356 °F (180 °C) for 35 seconds. Pretreatment must be cured with the heat press instead of oven to keep the
surface flat and smooth.

When you print with White ink, we recommend using oven instead of heat press. (320°F (160 °C), 3 and half
minutes with the tunnel 2.4 meter long as a rough indication.
Separator sheet (parchment):
Be sure to use this to make the surface smooth and flat in curing the Pretreatment and Ink, especially with
White Ink.
Urethane mat (continuous foam):
Use this to release the hot air quickly in curing Pretreatment.
T-shirt (printed material)
Cotton 100%
Light-colored polyester-mixed cotton (cotton should be 50% or more)
Dark-colored polyester-mixed cotton (cotton should be 70% or more)
<Note>
 Some manufacturing brands may not work as good as 100% cotton garment.
You need to test prior to your production, especially when you print on something new and unknown
materials.
 Pretreatment on some T-shirts may be seen after applied and cured. In that case, wash lightly with water
to remove the mark.
 The following issues may occur with Pretreatment. Test before you print.
* Some of the dyes used for some manufacturing brands or the models, or even the difference of lots,
may be decolorized by Pretreatment; we recommend you test the garment before printing.
* The dye in dark-colored polyester-mixed garment can easily come out, called “dye migration" and may
color the White Ink (especially the garment with 70% or less cotton mixed).
